2016 ACURA MDX Engine Problems

NHTSA Incident Report Vehicle: 2016 Acura MDX Date of Incident: [XXX] Location: Oregon (Oregon Coast to Portland) Mileage: 110, XXX Incident: During a 60-mile road trip, the vehicle unexpectedly shut off and shifted into neutral. The car coasted safely to a stop. Earlier, we had noticed a slight knocking sound when starting the engine, but no other issues were present. A tow truck attempted to jump-start the vehicle without success. Ron Tonkin Acura later confirmed engine failure. The vehicle has been regularly maintained, with documentation, and had no prior engine problems. Acura has stated that this failure is not part of their rod bearing recall. No warning lights appeared before or during the incident. Safety Concern: The sudden engine shutdown created a serious safety risk while driving. Requested Action: Investigation into potential defect causing unexpected engine shutdown in the 2016 Acura MDX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While my teenage son was driving on busy interstate highway the engine began making extremely loud noises and smoking while losing power. Driver was unable to make it to a safe exit and had to pull over with limited shoulder, in a very dangerous spot. All oil leaked out of the engine an onto the roadway, also a hazardous and dangerous situation. Car was towed to Acura dealership and inspected. Catastrophic engine damage - part of the engine rod assembly was launched through the oil pan and lodged in the air conditioning compressor. Vehicle had 87K miles and all service was performed. Complaints that the engine was lagging and making noises at low RPM's had been expressed to Acura for years. I was told that unless a check engine light came on there was no way to know what was wrong.

I purchased a 2016 Acura MDX during the summer of 2025. I am the second owner. In November 2025, the engine starting experiencing engine knock later to be confirmed as rod bearing knock. This vehicle if a 2016 MDX and the manufacturing date is October 2015. There is a rod bearing recall for 2016 MDX's however, my VIN is not included in this recall which is ludicrous as it is experiencing the same issues as the recall with only 80,000 miles on the engine. I urge you to widen the recall to include 2015 MDX vehicles as there is no way this Acura MDX should be experiencing rod bearing issues on a well taken care of vehicle.

​On November 28th at 10:00 AM, my 2016 Acura MDX suffered a catastrophic and sudden engine failure that resulted in a total loss of motive power. I was driving on Scott Boulevard in Santa Clara, just after exiting the Central Expressway. ​I first heard a loud metallic noise, and the engine immediately seized and shut down. The vehicle started slowing rapidly on a busy street, creating a life-threatening safety hazard for myself and other drivers. The car spontaneously shifted into Park and it was difficult to manually shift into Neutral for towing. Thankfully, no accident occurred. ​The failure is due to a connecting rod bearing failure and engine seizure. This is the identical safety-related manufacturing defect acknowledged in Safety Recall 23V-751 and is currently the subject of the ongoing NHTSA Preliminary Evaluation (PE25008), which covers the same 3.5L V6 engine in vehicles outside the original recall, including the 2016 MDX. I feel responsible to report the incident to NHTSA to take precautions on the matter. Regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2016 Acura MDX. The contact stated that while driving approximately 15 MPH, there was an abnormal sound coming from the engine compartment. There were no warning lights available. The vehicle was taken to a dealer, where it was diagnosed with a fractured connecting rod bearing, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 97,000.

Mileage: 97,000

When car is started, attempting to slowly accelerate in reverse or forward you will experience a loss of drive power, transmission does nothing. Then all of a sudden transmission responds and you lurch forward or reverse. Very unsafe situation. Other cars not sure if your moving or stationary.

Started hearing a "knocking" sound from the engine compartment, whose frequency clearly was proportional to engine RPM. Took vehicle to local trusted mechanic who diagnosed that it was likely related to known crankshaft bearing issue, which is the subject of a widespread recall on Acura vehicles. Found that the vehicle does not fall within the recall window. Sent vehicle by tow truck to nearest dealer who confirmed diagnosis. They claim poor maintenance, but all required maintenance, and definitely all engine oil changes were completed at required intervals with proper fluids and filters. Since dealer is 60 miles away, most maintenance was done with local trusted mechanic, although some oil changes were done personally or at a quick lube service. The vehicle is a 2016 model year, consistent with the model years affected by the known defect and recall. Dealer is advising that a new engine is required. There is no reason a properly maintained vehicle with only 150,000 miles should have a failed engine.

I have a 2016 Acura MDX with 87,000 miles that has bad rod knock. Service Bulletin 23-036 talks about it. Even though my MDX's VIN is not listed in the recall, I am having the exact same problem the recall is supposed to be for. I feel this recall should be expanded to cover my vehicle as it is listed in several places that the recall is for all 2016 Acura MDX's which is what my vehicle is. ------------------------ Subject: Safety Recall: 2015–20 Multi-Model Connecting Rod Bearing Stop Sale. Affected vehicles: Certain 2015–2020 Acura TLX V6 and 2016–2020 Acura MDX models. Cause: A manufacturing defect in the crankshaft can lead to connecting rod bearing wear due to lack of lubrication and excessive heat, potentially causing engine damage and failure. Action: The bulletin initiates a stop-sale order for affected vehicles and provides instructions for inspection and repair, which may include replacing the connecting rod bearings, crankshaft, or short/long block. Status: The bulletin has been revised. Version 1 was issued on November 9, 2023, and was replaced by Version 2 on February 9, 2024. Parts Availability: Parts and repair kits became available in early 2024, with repairs being prioritized for vehicles showing symptoms like engine rod knock or stalling.

The MDX drove perfectly until out of sudden there as a stall, knocking and ticking sound in the Engine. It is diagnosed with the connecting rod failure and needs a new engine replacement. The car was well and regularly maintained with oil changes and services as recommended. The following codes were pulled from the ECM: Code P0301, P32638

The vehicle frequently experiences problems while idling at red lights or stop signs. Specifically, the engine suddenly shuts off after displaying a message that "Idle Mode is unavailable." This has occurred multiple times, and on five separate occasions, the vehicle became completely immobile, requiring towing to the nearest mechanic. Initially, I had the flywheel and starter motor replaced, which cost me approximately $5,000. However, just three months later, the same issue reappeared. Most recently, while driving home from work, the idle mode failed again at a stop sign, and the engine stopped running. I contacted Acura/Honda regarding this issue, but they informed me that it is not their responsibility. At this point, I am unsure how to proceed or where to seek a reliable fix, and I am concerned about the safety implications of this recurring failure.

Car broke down driving from Dallas to Oklahoma on the highway while at cruising speed. We were able to pull over safely and after towing the car home, the engine produced a knocking sound. Upon further investigation, there is a recall for rod/bearing issues with 2016-2020 Acura MDX's and other various models like the Acura TLX, Honda Pilot, etc. This only extended to certain models and there has been more affected by it than what the recall covers. Maintenance such as regular oil changes to big services like timing belt and water pump was done according to the service manual interval. Investigation RQ24013 was open on 11/08/2024 by Investigator Richard Lawrence, Reviewer Sharon Yukevich, and Approver Tanya Topka. There have been about 173 incidents and pose a great safety hazard. Once the car is stopped, the car is not able to go into neutral without the engine on. The only way to override this is through the engine bay with a tool of some sort to manually engage the neutral switch. If the car stops in the middle of the road with this engine failed, this could lead to a more severe casualty

Engine cut out on the middle of a pitch black highway in Virginia. Few seconds lights flashing on dashboard check engine light started flashing then low engine oil and then the rest of the standard "CHRISTMAS TREE LIGHTS" experience as I was finally able to pull the vehicle over. Vehicle seemed as if it was dead. When got vehicle JUMPED 2 hours later I started engine because it wouldn't start. It was making all the noises consistent with ENGINE recall that MY ENGINE was so conveniently not included in the recall. ACURA WON'T DO ANYTHING for me. I was stuck on the side of the highway in the pitch black with cars and trucks flying by at 70+MPH with my 3 kids and spouse. ENGINE is chattering and has no power. ALMOST ABOUT TO SEIZE. I was stranded in a small town for 2 days with no way to get home no rental companies with cars available. ALL VIDEOS online consistentfor engine recall consistent with my experience. NO lights no hestitation perfect engine oil level filled tank of gas minutes with 93 as always not even 2 minutes before this situation. ENGINE WAS PERFECT. Was glad I wasn't apart of recall initially. I thought I had a "GOOD ONE" then boom complete catastrophe. NHTSA NEEDS to expedite this. THIS IS NOT ROCKET SCIENCE! Acura knows the issue they are running form it. I spent over $1,100 to tow my vehicle home and get my family home safely.

Hello. I went to the Acura dealership because I got a recall letter. I lost the letter itself a few days ago. I also had the check engine light come on once while driving. But then it went out on its own during the same trip. At the moment of checking my car by my foreman, he heard a knocking noise in the engine. He said that they will check my car on the recall and see what's wrong with the engine. After some time, he called me and said: I am very sorry, but you need to replace the complete motor as this knock is caused by a problem in the bearing. And alas your car does not fall under the recall to replace this bearing. I asked him which bearing he was talking about. And they answered that it was the one that goes into the recall under which my car did not fall. I clarified that its name sounds like: connecting rod bearing? He said: Yes. I've had all my maintenance done on time. Engine oil changes every 5,000 miles. Even before the 8,000 to 10,000 miles. I have all the paperwork with receipts and dates in my car paperwork bag. At every oil change no one has ever told me there was an engine problem. The car was purchased from a dealership in Libertyville, Illinois. The car is currently at a dealership in Naperville, Illinois. I wrote a complaint to Acura of California on 9/26/2025. To date, all I have gotten is a response: we have a lot of work to do, we will respond when we can. Very rude and disrespectful. Considering I could have been in an accident if the engine had seized up. That's what my foreman at the dealership said. Or even worse, my daughter could have had an accident. I was planning to give this car to my daughter since she got her driver's license. She really liked this car. Now I don't know what to tell her. I am asking for your help to resolve this problem. They still haven't contacted me or told me what to do. Appreciate it.

No prior issues with vehicle when all of a sudden/out of the blue the check engine light started flashing and felt decreased power. Pulled over, had it towed to dealership. After it was diagnosed they advised of a rod bearing failure, crankshaft failure and metal shavings in the oil which went through the engine. There is a recall for 2016 Acura MDX for this EXACT issue, however for some reason my VIN is not included?? The recall was effective Nov of 2023. I purchased vehicle Feb of 2023. Vehicle is still at shop as a complaint has been filed with Acura.

On 9/12/2025 driving on the highway in stop and go traffic, the idle stop feature engaged, but the engine would not restart upon taking foot off break. Put vehicle into park and held start/stop button for couple seconds to turn off, then was able to restart vehicle by pushing start button. Couple days later went to start vehicle while parked and accessories came on, but engine wouldn’t start. After a few attempts, got vehicle to start.

I have a 2016 Acura MDX, recently took it to Oh Acura in Temecula for a check due to a noise coming from the engine. Acura determined I need a new engine.. the issue being rod bearing failure Acura determined I need a new engine.. the issue being rod bearing failure. Upon research, this is a known issue from 2023. Also, a new investigation with engine failures in Honda and Acura vehicles linked to the rod bearings has been opened.

One morning I noticed the engine in 2016 Acura MDX was making a loud knocking noise. The check engine light immediately came on. As such, I immediately drove to Acura of Baton Rouge to report the problem to get it fixed. They ran a diagnostic on the car and didn't find anything. For some reason they said they needed to take the oil pan off to see if there was metal in the oil pan. I said ok. I got a call a few days later from the service department stating that I needed a new engine at the price of $8,000 because they said a connecting road bearing had failed which destroyed the 6th cylinder. The vehicle only had 78,000 miles on it. The oil had always been timely changed. There is no reason the connecting rod bearing should fail on an engine with 78,000 miles on it. I contacted Honda and Honda eventually came back to me and said they would not do anything to help replace the engine because the car was not under warranty, despite the Office of Defect having an ongoing investigation into connecting rod bearing failures in 2016 Acura MDX's. Honda has not operated in good faith, this is a major safety issue and the federal government must do something before people are hurt as a result of Honda's negligence.

While driving on the freeway with my children, the vehicle started to shake and the emission system problem, transmission system problem and blind spot problem lights came on. The safety of myself and children were at risk due to being on the freeway and having to pull over on the side of the road. There were zero signs leading to this.

Engine failure. McGrath confirmed the engine had the same rod issues as described in the recall. Corporate refused to cover the repair.

The contact owns a 2016 Acura MDX. The contact stated that while driving at 65 MPH, there was an abnormal knocking sound coming from the engine compartment. The vehicle was taken to a dealer to be diagnosed, and it was determined that there were metal shavings inside the oil pan and that the engine needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 87,172.

The contact owns a 2016 Acura MDX. The contact stated while driving 65 MPH, the vehicle stalled. Additionally, there was loud popping noise coming from the engine compartment, with the check engine warning light illuminated. The vehicle was able to restart. The vehicle was towed to the dealer, where it was diagnosed and determined that the connecting rod inside cylinder #2 had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 109,311.

Catastrophic engine failure occurred while driving on July 4, 2025, resulting in the car briefly stopping at 60mph skidding tires on I-70 (a major highway in colorado), then tires unlocked and now engine moving again but with a check engine light, and acceleration was sluggish. It freaked out the family and we pulled over at the next exit to find the engine was knocking like crazy. No injuries occurred, but the sudden engine failure while driving created a serious safety hazard. Complete loss of power could have resulted in accident if this had occurred in traffic, on highway, or during emergency maneuver. We later found out engine the rod bearing failed on cylinder 4 and shattered in several pieces. We took it to both independent auto repair shop, then the dealer, both confirmed rod bearing problem, and engine replacement now required. Dealer is quoting us $24000. Failure was due to connecting rod bearing failure - a known defect currently under NHTSA Investigation RQ24-013. This failure is consistent with NHTSA Investigation RQ24-013 covering connecting rod bearing failures in 1.4 million Honda/Acura vehicles including 2016 MDX. The failure appears related to unaddressed ATF warmer defect covered under Acura's KG9 warranty extension (Service Bulletin 17-026) that compromised cooling system in December 2024, leading to thermal stress and bearing failure. Acura was aware this defect was serious enough to warrant 10-year unlimited mileage warranty coverage but failed to honor it. We had the car serviced June 25th 2025 at the dealer just 9 days prior to the July 4th 2025 incident for its regular maintenance oil change, brake fluid flush, and valve adjustment.

While driving on the highway this vehicle shifted into neutral and lost power. Once pulled to the side of the road, the vehicle was able to be turned off and re started. This happened to my teenage daughter without warning.

My vehicle is showing the exact same symptoms that the 2016-2018 MDX fuel pump recall is stating but my VIN number is not part of the vehicles being recalled. I reached out to Acura relations and unfortunately, they cannot provide authorization to repair my fuel pump even though my vehicle falls under the same years that this model is being recalled for. I went to an independent shop to try and understand what the problem with my vehicle is and I was told that the high pressure fuel pump seems to be failing and was asked why I have not taken the vehicle to the dealership for the fuel pump recall. Due to this issue I am unable to properly use my vehicle. If i step on the accelerator too hard, the vehicle gets engine misfires and immediately goes on limp mode.

On August 29, 2024 my vehicle stopped working. I was driving through a busy Costco parking lot. We stopped to wait for a car to turn, the auto engine idle turned on. When we removed our foot from the brake that car wouldn't move. It wouldn't start again, everything seized up. We couldn't push the car because the tires locked up. We called a tow truck, luckily we were not in a parking spot because the tow truck driver had to pull it on the bed. The vehicle was towed to Stephen Wade Honda, they have always maintained our vehicle and done the recalls when able to. The nearest Acura dealership is 127 miles away. We were told that the engine suffered catastrophic engine failure. I reached out to Acura and a lady on the phone said she was sorry there was nothing Acura could do. I want to know why my vehicle is not under recall for catastrophic engine failure.

driving on freeway at 65mph and check engine light flashed as vehicle started to studder and turned off while driving. vehicle would not even try to start afterwards. vehicle got towed off freeway to my home. I continued to try to start, it sounded like a bad starter or dead battery, so I charged the battery and got the vehicle to crank and start. engine was knocking and squealing and pinging. immediately turned off and did some research. found out about recall and my engine is not on it . I found a local shop and had it towed there. it ended up being a bad rod/bearing in the engine. I had to have the engine replaced.

On Sunday, while driving approximately 70 mph on the highway with my two young children in the car, the check engine light began flashing, the vehicle suddenly lost power, and would not accelerate past 60 mph. The engine then began producing loud clanking or knocking noises. I pulled over as quickly as I could and had the vehicle towed to my local Acura dealership. The technician who inspected the vehicle indicated it is in the early stages of catastrophic engine failure—likely due to a spun rod bearing. These symptoms are nearly identical to those described in NHTSA Recall 23V751000, which addresses rod bearing failure, sudden loss of power, and potential engine seizure in certain Acura models. A less severe version of this issue occurred a few days earlier, on Thursday, also while driving on the highway. The check engine light began flashing and the vehicle experienced a noticeable loss of power. I pulled over and restarted the vehicle, and that resolved the issue. I drove the vehicle multiple times—including on the highway—between Thursday and Sunday with no further issues until the much more severe failure occurred. Despite the clear safety concerns—and the fact that both incidents closely mirror the description in Recall 23V751000—my VIN is not currently included in the recall. The vehicle has fewer than 90,000 miles and has been maintained exclusively at Acura dealerships. I’ve reported this to Acura, and my case has been escalated for internal review. An Acura representative encouraged me to contact NHTSA directly, as your agency is responsible for determining whether the scope of the recall should be expanded. This is a serious safety issue that occurred without warning—at highway speeds, with children in the car – and put my family at risk. I respectfully request that NHTSA investigate and consider expanding Recall 23V751000 to include similarly affected vehicles like mine. Thank you for your attention to this matter.

While driving southbound on I-5 from San Francisco to Anaheim, the vehicle began making rattling and squeaking noises from the engine compartment. Within minutes, multiple warning systems activated, including alerts for power steering, brake system, ABS, and other critical components. The vehicle quickly lost power and could no longer shift gears. We were forced to exit the highway near Kettleman City, but the engine completely shut off as we were exiting. Brake pressure was lost, and the vehicle could not be stopped using the primary braking system. We had to use the emergency brake to avoid a collision. The vehicle was towed by roadside assistance to a dealership for inspection. The dealer confirmed that the engine had spun a connecting rod bearing in cylinders #3 and #4, which caused piston damage and full engine seizure. The service department acknowledged this failure matched a known recall (Recall No. 23V-751), but stated the vehicle was not eligible for repair due to its VIN not being listed. Despite this, the failure is identical in cause and outcome to those covered by the recall and poses the same safety risks.

Driving up a hill, new knocking noise, car lost engine power, steered the car to the curb and turned engine off. Got car towed to mechanic, ultimately diagnosed as connecting rod bearing failure at cylinder 1. No noted leaks nor other issues at engine nor transmission, this appeared to be defect of the connect rod itself.

Mileage: 66,701

The contact owns a 2016 Acura MDX. The contact stated while driving 65 MPH, the contact felt a big bang with an abnormal sound coming from the engine compartment before the vehicle lost motive power. The contact stated that the vehicle then stalled. The contact inspected the vehicle and observed a liquid pouring out from the engine compartment onto the ground. The vehicle was not able to restart. The vehicle was towed to an independent mechanic where it was diagnosed that the engine needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 92,380.

Recall 23V-751 affecting certain or maybe all 2016 Acura MDX SH-AWD connecting rod bearing failure. The vehicle came to a sudden stop on the freeway after a loud terrible sound from the engine. This left my wife and child on a freeway exit ramp with no way to navigate the car to safety. The vehicle won't start, it makes a terrible clanging noise and stops. It has a seized connecting rod bearing and now a broken connecting rod and several holes punched from the broken rod. It was immediately towed to an Acura Service Center where it was confirmed. Recall 23V-751 described this failure exactly yet my car VIN is not included in the recall even though it is clearly affected by that recall. Acura Client relations refused to add the VIN even after saying they would if the problem was confirmed by an Acura Service Technician which it was but they refuse to add the VIN and repair the SUV.

This specific vehicle has an issue with the starter and flywheel breaking up for no reason. After being replaced twice, they were broken again in three months. The suspension has also been broken many times, and even after replacing the entire four sides, it still did not fix the problem. It also produces a rubber smell when driven over than 1 hour non stop

The engine light came on more than 12 times in the past 3 months. I tried to have the dealer check, but they found nothing. Then the light started to of on and off every time I drive in the rain

I purchased a used 2016 Acura MDX and shortly afterward began experiencing a rhythmic metallic knocking noise under load, particularly at low RPMs (e.g., accelerating in low gears or when the engine is bogged). The noise is not present at idle or during coasting, and it closely matches the symptoms described in recall 21V-215, which affects certain 2016–2018 Acura/Honda models for premature connecting rod bearing wear. However, my vehicle’s VIN is not included in the existing recall. I purchased a used 2016 Acura MDX and shortly afterward began experiencing a rhythmic metallic knocking noise under load, particularly at low RPMs (e.g., accelerating in low gears or when the engine is bogged).

However, my vehicle’s VIN is not included in the existing recall. This vehicle has received on-time oil changes using high-quality synthetic oil, and I have taken care to immediately investigate any new or unusual noises. The knock has persisted across multiple oil changes and several thousand miles without worsening, but recently I noticed metallic sparkles in the used oil—potential signs of rod bearing wear. There has been no Check Engine Light, but based on the symptom pattern, operating conditions, and consistency with the defect description in recall 21V-215, I believe this vehicle may be experiencing the same issue and is simply outside the current recall range. I am submitting this report in support of the ongoing Recall Query (RQ) into whether Honda failed to include all affected VINs. This appears to be the same failure mode as those already recalled, and it presents a serious long-term risk to engine safety and reliability.

***THIS IS A RESUBMIT WITH CORRECTED INFORMATION*** I purchased a used 2016 Acura MDX from a family member, and shortly afterward began experiencing a rhythmic metallic knocking noise under load, particularly at low RPMs (e.g., accelerating in low gears or when the engine is bogged). The noise is not present at idle or during coasting, and it closely matches the symptoms described in recall 23V-751, which addresses premature connecting rod bearing wear that may lead to engine failure in certain Honda and Acura vehicles. However, my vehicle’s VIN is not included in the existing recall. The knocking has persisted across several thousand miles and multiple oil changes. I recently inspected the drained oil and found metallic sparkles/particles, which may indicate active bearing wear. There has been no Check Engine Light, and the vehicle has received on-time oil changes using high-quality synthetic oil, with immediate mechanical inspection when the noise first appeared. I know for certain the previous owner maintained the vehicle properly, as he is a family member and I occasionally helped with maintenance myself. Based on the symptom pattern, operating conditions, and consistency with the failure mode described in 23V-751, I believe this vehicle may be affected by the same underlying defect, but is excluded due to an overly narrow recall scope. I am submitting this complaint in support of Recall Query RQ24-013, which is currently under review to determine whether Honda failed to include all affected vehicles. I am concerned this poses a long-term safety and reliability risk, and that vehicles like mine are being improperly excluded from coverage. It is available for inspection. I am deeply concerned for my significant other to drive my vehicle in any capacity, and myself as well. I have videos as well. Please reach out if you need them because the bearing has not spun out yet.

Engine shut off due to rod bearing failure

The rod bearing went on this car. I don't understand how there was an open recall but this car was NOT included with the issue. This makes no sense to me. This was a huge cost to my hard working family to fix and Acura was less than helpful esp considering it was an actual recall for our car year. But due to our luck, our car was NOT included. I feel that this needs to be investigated further because more cars were impacted by this recall than were deemed to be included. I reached out previously on this matter to this organization and received NO response.

I purchased the vehicle in 2017. It was certified used by acura dealer but it was practically new; less than a year old with 10,000 miles on it. About a month or so after purchasing I started noticing a an issue when pressing on the gas and the vehicle not responding and a few seconds later it would suddenly jerk trying to catch up to the gear it should be on. Right away I took it to dealership for them to inspect and they said the vehicle needed a "software update" and it should be fine after that. Long story short, it is now 2025 I've taken the vehicle in for a "software update" more times than I can count and I am still living with the same problem. On occasion it gets better and sometimes it gets worse. Especially at higher speeds when the gears seem to go to neutral for a few seconds and then re-engage again on its own which cause jerking/stalling motion.

My Acura MDX 2016, when stopped in traffic or at a red light will randomly shut down or switch to neutral. It started 2-3 years back. This has happened frequently last few months. Last time i was stuck in the exit of a parking garage blocking the exit. After around 20-30 mins the car decided to start on its own. I took the car directly to a dealer who found no issues with the car. I had the battery replaced recently with a new battery Upon searching the internet, i found this link where each person is describing the same issue [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I drive a 2016 Acura MDX, with less than 80K mileage. My car has an idle stop feature which was not working and I was having trouble starting my car in the mornings when it was cold. I assumed the battery was getting low, replaced to a new battery and the idle stop began working again momentarily. However, after coming to a stop and the idle stop feature engages, the vehicle was not always automatically restarting. More than once a day it turns off engine as intended with idle stop, but then my car shifts into Neutral and the engine fully dies. I'm left at stop lights or stop signs with a car that is off and will not restart. The last instance I was almost hit by a car when the light turned green and I could not drive forward. I have to shift into park, turn the on/off button, press my foot on the brake and push on/off button 2-3 times to get the car to start back up. All of this on a battery that’s less than a week old. More often then not the idle stop is not working at all. I’m left with a message on my dashboard “auto engine idle stop unavailable.” My VIN was not listed under the Acura SB to “update the PGM-FI software that may affect the idle stop operation and starter under certain conditions.”

Due to a manufacturing defect of the engine crankshaft, the connecting rod bearing prematurely wore and could seize. This is a recall for 2016 MDX V6 engines, my VIN is not included for some reason.

My Acura mdx 2016 has always had oil changes on time . Also only 93 octane gas . Online there are 100’s of people complaining about my issue which there is a recall for same year make and model but my vin is not included. The recall is for rod knock , and this is what I’m experiencing right now out of nowhere. And Acura will not own up to it very upset . This is a very dangerous situation that can cause an accident with my family in the vehicle . Do to engine lock up .

Connecting rod failure causing the need for engine replacement. This connecting rod has been part of a recall campaign by Honda for 2016-2020 MDX models, but this 2016 engine VIN [XXX] is not part of the recall, even though the SAME EXACT issue as the recall is what occurred. Acura is refusing to honor the recall. This happened while on a highway in the California mountains, going uphill, putting my entire family at risk as the vehicle lost power and became inoperable. The dealership confirmed the connecting rod failure, but informed me of Acura's denial on the recall claim. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2016 Acura MDX with only 120,000 miles on it. Recently I started hearing a knock coming from the engine. I have taken it to three different mechanics, including an Acura dealership mechanic. I was informed by all three to not drive the car due to the fact that it was a rod bearing defect/problem. They all commented that I was lucky that it had not thrown a rod or I could have been injured or possibly had my engine freeze up while driving injuring myself or someone else. After some thorough investigation/research, I have been informed that my make and model has been recalled for the same issue, unfortunately, my Vin number is not included in the recall for whatever reason.

What component or system failed or malfunctioned, and is it available for inspection upon request? The motor's rod bearing spun. It is available for inspection. How was your safety or the safety of others put at risk? The failure could have created enough friction between the bearing sleeve, rod and/or journal bearing to seize the motor and the drivetrain while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes the vehicle was taken to the Acura dealership to be inspected, diagnosed and repaired. There is a recall for the same year, make and model but my vehicle's VIN is not included in the recall. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has only been inspected by the Acura dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There was a check engine light that produced code P0430 (Catalyst System Efficiency Below Threshold Bank 2) and P0306 (Cylinder 6 Misfire Detected). The vehicle had a loss of power and troubles accelerating under load. The first time the problem was noticed was January 18th, 2025.

My Acura mdx 2016 is well maintained, only 42500 miles,bought brand new from dealer, problem started 6 months ago, accelerator, rpm goes up even on 20 miles driving, and car just stops and gear goes to park mode..dealer inspected, they said transmission needs to be replaced, contacted NCDS, their respond I passed the warranty of 7 years, not covered. Dealer charging 7100 to fix issues.

Mileage: 43,000

After starting the engine, when attempting to slowly accelerate, the engine almost dies or hesitates to respond to accelerator. Dangerous situation.

Problem started with Check Engine light coming on, then going off, then coming on again followed by what seemed like all system failure lights getting reported. A clicking/rattling started to be heard in the engine. When driving the vehicle to the dealer to get it inspected the vehicle engine cut out while cruising at 45 MPH. I was able to roll to a stop on the side of the road luckily, it would not start and needed a tow to a more local related dealer (Honda) repair. Honda repair did not move past reading the codes, so I transported the vehicle via a service to the nearest Acura dealer, where they diagnosed the internal rod problem, with the fix being a replacement engine. The vehicle remains at this Acura dealer service.

Mileage: 115,911

I was driving down the road & without any warnings my car suddenly loss power. Engine started a really bad knocking sound then stalled out , took to certified mechanic and he told me I need a new engine. Prior to this there were no boarding likes or issues related to the car.

Loud Clicking sound, engine light blinking, car was shaking horribly almost caused an accident.

“Emissions system problem” warning light has lit up on dashboard twice. This was checked and found to be a faulty code both times however, the second time it occurred, it correlated with the sway bars needing to be replaced.

Engine knocking noise, irritable shaking while on road, dangerous driving conditions. Engine Failed and diagnosed at Acura Dealership as failing bearings and connector rod. This issue is under investigation NHTSA Action Number: RQ24013 and I am currently being forced to pay out of pocket for the repair amounting to several thousand dollars. Acura needs to recall these engines NOW and get it fixed. This driving condition is EXTREMELY unsafe, the entire car shakes uncontrollably. This car was bought brand new from dealership by myself. 1 owner. Always serviced at Acura or Honda dealerships.

I have a 2016 Acura MDX with nearly 79,000 miles on it. It died without warning late at night while on the freeway on [XXX], leaving my [XXX] son stranded alone in a dark, remote area for about an hour. Not a safe situation! I had it towed to Shadetree Auto in Layton, Utah. They informed me that the engine had seized. What!? It was well maintained and just had the oil changed a few days previously. They wanted over $11,000 for a used engine. (See Attached Invoice & Report). They couldn't figure out why a well-maintained engine with only 79,000 miles on it would just seize up. Coolant was also not the issue. I couldn't afford it, so it sat for a couple of months until I discovered that there was a Recall on that year for faulty connecting rod bearings that was causing engines to seize. So, I checked into it, but my particular VIN # was not included in the recall. I found a copy of a letter from Acura stating that they were still determining the extent of the problem, nevertheless, they rejected my claim as not included, rather than extending the recall to include my vehicle's documented problem. (See the attached Acura letter dated Feb 7, 2024). I had my car towed to Jody Wilkinson Acura in Salt Lake City for a detailed inspection and second opinion and they confirmed that the engine was seized and that it I had a broken connecting rod on cylinder #1 due to a spun bearing (See photos at the end of attached email). But Acura continued to deny my claim. Jody Wilkinson's quoted me over $20,000 for a new engine. I asked Acura what the appeals process was and they said "there isn't one, we just won't cover it". Seems like Acura may be [XXX] a lot of people. Why would I put another known faulty engine in my car? Absurd! I have attached the following documents: •Shadetree Auto Inspection Report & Invoice •Acura Letter Feb 7, 2024 •Jody Wilkinson Inspection Report Your help in obtaining justice would be greatly appreciated!

While driving on an interstate highway at 73 mph, under cruise control, at night, as the road started to incline up a hill my vehicle started losing power. The highway is two lanes each way, and I was in the left-hand lane passing a slower vehicle that was in the right-hand lane. There were cars behind me in my lane. When my car started losing power, the check-engine light came on along with some other indicators. I attempted to maintain speed by depressing the accelerator, but the car continued to slow down. It was nighttime when this happened, on a pitch-black highway that had been freshly paved. I was able to finally get behind the car I had been attempting to pass and was then able to get into the emergency lane and stop. My car was making a ticking noise. I turned off the car, opened the hood, but it all looked fine. I looked under the car - there were no fluids running out of the car. I checked the oil, and it was at the full mark on the dipstick - I had changed the oil about 1000 miles prior to this event. When I took the car to a local Acura dealer, they told me that the noise I was hearing was "rod knock", and that it would cost about $8000 to repair by purchasing a short block and having them install it. When I started researching the issue I learned that some 2016 Acura MDXs have a known issue of incorrect rod bearing size, but that my vehicle is excluded because it was evidently manufactured before a certain date. My car has only 125,116 miles on it. It is maintained meticulously. Please investigate.

Vehicle always smells hot or as if something electric is burning in the engine compartment. Have always had scheduled maintenance and have taken it in on time for all oil changes and maintenance to be performed. Have asked for this to be checked at that time and when the smell has become over powering. Engine lights have popped up and then all lights have shut off two separate times previously to the point where I had to turn off the vehicle. I have taken it to two dealerships and another mechanic to look for the cause. They are not able to determine the cause but recommend I contact Acura as this sounds like a warranty issue.

This occurrence with the vehicle happened in October of 2023 and I no longer own it. The only reason I'm reporting it today is because of the news reports I've been seeing about a possible investigation into the exact issue I experienced. I started to hear a knock from the engine that got progressively worse over the course of a week. I made an appointment to have it looked at, but before I could even make it to that appointment multiple dash lights and warnings started showing up on the meter combi. Engine light was the first to appear followed by the transmission light, then the vehicle went into "limp mode." It wouldn't go over 30mph and eventually just shut itself off; every warning lamp on the dash was on. It was towed to a local Acura dealership where the service tech diagnosed the issue and stated it was a connecting rod bearing that had worn prematurely and there was movement in the piston. I had them check for a recall then and my VIN was not on the list so I proceeded to source a motor and have another shop swap it for much cheaper. That being said, I would very much like to be reimbursed for the costs I incurred. I have multiple documents and at one point had a video that the dealership tech sent me showing the defect. Not sure if they can provide that now or not.

The engine started to make noise, drove it to the Acura Dealership. The engine seized at the repair bay. The technician initially said they just had a recall on these engines then after looking up the ID notified me that the blown engine was not covered under the recall. After several calls to Honda corporate customer service they informed me that they knew it had a faulty engine however it was not under the recall and they didn't have to repair or replace. I paid the dealership to install another engine at my own expense.

The contact owns a 2016 Acura MDX. The contact stated that while driving on several occasions at various speeds, the vehicle lost power. The vehicle was steered to the side of the road after each failure and restarted. The contact stated that an unknown fault code was displayed occasionally. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 70,000.

Mileage: 70,000

Engine blew a rod at 130,000 miles. Replaced engine. Maintained vehicle correctly And changed oil regularly. contacted Acura, but no help. Other vehicles reported similar problems and recalls issued., but not for my particular vehicle.

Driving on [XXX], car began to make a loud noise, began to lose power and smoke was pouring out of the engine. No check engine lights came on. Pulled over immediately and turned off engine, and smoking continued. Car was in a unsafe location and we had to wait an hour with traffic very close for a tow truck. Large quantities of oil leaked out of the engine. Car was towed to Niello Acura in Roseville CA. They diagnosed Catastrophic Engine Failure. Large hole in oil pan and wrist pin found lodged between A/C compressor bracket and engine block. Wrist pin secures the piston to the connecting rod (there is a recall on Acura MDX's for this but my car was not included) Needs new engine.

I am [XXX] and I have owned Honda/Acura since I was 16 yrs old. My last vehicle was a Honda Odyssey minivan with 423K when I donated it, running well to a family that fostered kids! I bought a new 2016 Acura MDX and now it is 8 years old and has 180K on it. I get the oil changed and other normal service maintenance done only at Honda or Acura dealerships. I have never had a car accident and I take care of the maintenance early. All of a sudden, on Friday, [XXX], I had just started driving ( ~20 minutes in the car) and every light started flashing and the car sounded funny and it was hard to drive. I immediately got off the highway and found a repair place (Red's auto repair) right off the exit. They had me shut off the car. Then they checked the oil, which was showing 70%, and I had just had it changed less than 1000 miles earlier, and it had plenty of oil. They told me I could not drive the car! They said "something is wrong with the engine". Currently, LaFontaine Acura has my car. I have a loaner from them. They said it "spun a bearing" in the engine. Apparently there is a recall for this same problem for my year, make and model, but "currently" my VIN number is not included? And, it is the exact same problem bearing from the recall! THIS IS CRAZY! My car has been well taken care of and I would expect it to get at least 350k miles at least before any issues. If the same problem was recalled for other cars, why not mine? It is un-drivable now. I think that Honda has changed their manufacturing because in 43 years of driving Hondas they always are reliable and work well for years and years. My 5 adult kids drive Hondas as well! Never a problem. I think I got a vehicle with a defect that should not be, especially when the car has always been maintained so well, with the service records to show that. PLEASE HELP GET THIS INCLUDED IN THE RECALL FOR SAFETY! What is my next step to ensure that my car is included? Thank you very much INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

I was driving on the interstate going 80 when the car shut off. I coasted to the shoulder and had the car towed to the mechanic shop. The connecting rod broke, going through the engine causing me to need a new engine. When I contacted Acura they said my car wasn’t in the recall even though it’s exactly what was happening to other cars the same year and make as my car.

Failure of connecting rod bearings leading to complete engine failure.

I was driving my 2016 Acura MDX (approximately 87,000 miles) at around 60 mph on the freeway when the engine began making a metallic clanking noise. Shortly after, the check engine light started flashing, and the vehicle lost acceleration, eventually coming to a complete stop. This created a potentially dangerous situation, but I was fortunately able to pull over safely. After the vehicle stopped, the engine would not restart. The mechanic who inspected the vehicle confirmed that the engine has seized. This incident occurred without any prior warning signs and could have resulted in a severe accident. I believe this issue poses a significant safety risk to drivers and passengers. I request an investigation into whether this problem could be due to a manufacturing defect or systemic issue with this model.

I am the owner of a 2016 Acura MDX Advance. While driving, I noticed an unusual knocking sound coming from the engine, despite no warning lights or error messages prior to this incident. Concerned about the noise, I promptly brought the vehicle to an Acura dealership for inspection. The initial diagnosis revealed a camshaft issue, which was replaced. However, upon reassembly, the technician detected a persistent knock that required further investigation. After a week of detailed inspection, the dealership traced the problem to a defect with the rod bearing, an issue that has been part of previous recalls, though my vehicle was not listed. This rod bearing defect caused significant internal damage to the engine, ultimately requiring a complete short-block replacement to restore proper functionality. While the dealership has since resolved the issue, I am deeply concerned about the safety implications of such a defect. Had the rod bearing failed entirely, it could have led to an engine blowout, risking sudden loss of power at highway speeds and potentially endangering my safety.

Car had a failed crankshaft causing a rod bearing issue with the motor. The check engine light came on during use and car was taken to a local repair shop. The independent repair shop determined the issue is associated with recall TSB 24-001, and advised it be transported to a Honda dealership for repair. Honda confirmed that although the 2016 is under this recall this specific VIN is not. Car was repaired at Honda dealership with same exact repair kit and work done to fix the TSB 24-001 recall notice. Reached out to Honda customer service to understand why the car was not repaired under this current recall but was not given any additional information, case #14733117.

My 2016 Acura MDX with 113,000 miles on it suddenly experienced engine failure while driving my son to college in Salisbury, MD. The engine lost all power as I was coming off of the highway onto a side street in Salisbury. Fortunately no other vehicles were around me at the time and I was able to drift into a safe parking area. If it had happened on the highway or in traffic, it could have caused an accident. There were no warning lights on and the vehicle seemed to be running normally right up until it lost power. After having the vehicle towed to an Acura dealership, the mechanic found a broken rod that was likely due to a bad rod bearing. Other 2016 Acura MDX's have been recalled due to a defective rod bearing resulting in engine failure, but my VIN is not covered under the recall. Honda National just confirmed that it will not cover my MDX's repair under the recall. Prior to this, I had done all required maintenance on the vehicle.

The car began making a front end noise and running shoddy and when we took it to the dealer they had to replace bearings/short block at 121k miles. We were told our VIN was outside of the previous recall so it wouldn’t be covered under that. We ended up paying a portion of that very large bill which inconvenienced our family. We were without our own vehicle for many weeks due to back ordered parts for the major repair. This car has always been serviced by Acura at regular intervals.

In July of 2024 my vehicle began to make a knocking sound from the engine. I started a claim through my third party warranty company and brought it to a repair shop. The shop informed me about the recall for my model and year vehicle, but my VIN was not included in the recall. It was determined that the connecting rod bearings failed, and after waiting for 6 weeks the engine was replaced with a used engine from the same year and model vehicle. I drove for about 1900 miles and the engine began knocking again. I returned the to the repair shop and the supplier of the engine provided another used engine. I am terrified that the same problem will occur again and feel the engine can fail at any time.

The engine failed and was unable to be repaired like old Honda and they had no interest in resolving the issue, nor do they offer any replacement with.

Engine started knocking and quit working while driving on the freeway. Was a connected rod bearing failure that was not included under the warranty or recall. Honda paid 75% of repairs but I had to pay $3300 myself.

While waiting to turn left from a busy street onto a highway, the engine seized. The car was unable to be moved from it's location in the center of the busy street with cars approaching quickly from behind and weaving around my stopped vehicle. I had the vehicle towed to Metro Acura in Montclair, CA and they confirmed that the connecting rod bearing had failed causing the engine to seize. They also confirmed that the vehicle is not part of the existing recall. The engine produced some rough noise prior to failing but otherwise did not provide any warning lamps or other messages.

We were on a highway drive to a state park 45 minutes from our house on [XXX]. 40 Minutes into the drive the check engine light flashed. We had just taken a long road trip from Minnesota to Ohio (and back again) the week before (10/15-10/20) and had NO problems whatsoever. We parked and read what we could online as to what to do. Checked the gas cap tightness, the oil, etc. and let the engine cool for 2 hours. Started the car and no lights came on. So we started driving home. 35 Minutes later ALL the lights on the dash came on. Scrolling through every system in the car-transmission, brakes, lane assist, etc. We pulled Over almost immediately. Turned the car off checked under the hood but nothing seemed glaringly wrong. It wasn’t overheating or smoking or anything. We tried to drive it directly to our mechanic. Got back on the highway and the engine would not get up to speed, just groaning. Worried we would be in danger on the highway we pulled over and called for a tow. The first mechanic that reviewed (just local not Honda) could hear a knocking in the engine. Towed it to an Acura dealership on 10/28/2024. The Acura mechanic there confirmed that it is a rod/rod bearing issue—but we don’t fall under the recall. The rod came loose in the engine, banged around, damaging the engine. Cost to fix is $10,000. This information came to us on 11/4. We filed a complaint with the Acura/Honda recall department that day. We have been waiting to hear their verdict (after their investigation) for the last week. We have been told multiple times that our car doesn’t fall under the original recall. But the Acura mechanic has confirmed it is the same issue.

Driving on the highway for the car to idle, slow down and shut off, causing us to go to the shoulder in a busy intersection. No fore warning just died and won’t start. Waited 20-30 minute to restart. The car will start but will not shift to neutral or drive.

The auto engine idle feature activated at a stoplight as normal, but when I lifted my foot from the brake to accelerate, the car shut down, shifted into neutral, and wouldn’t restart. This happenwd 3 times in the last two days , leaving me stalled in heavy traffic for several minutes before i can get the car started again. This is extremely dangerous.

I have the same issue but my vin does not meet the requirement. reading multiple forum and a lot of people having the same issue. NHTSA RECALL NUMBER:23V-751 MFR CAMPAIGN ID:OH6 CAMPAIGN DESCRIPTION:2016-20 MDX Conn Rod Inspect Recall RECALL DATE:11/08/2023 RECALL STATUS:17 Character VIN Required SUMMARY: American Honda Motor Co., Inc. (Honda) is recalling certain 2016-2020 model year MDX vehicles. Due to a manufacturing defect of the engine crankshaft, the connecting rod bearing can prematurely wear and seize. SAFETY RISK: If the connecting rod bearing seizes, the engine can be damaged and run improperly, stall, stop while driving, and/or not start, increasing the risk of a fire, crash or injury.

Our engine is exhibiting symptoms currently related to an open recall by Acura for Connecting Rod Bearings. Our 2016 MDX is one of the affected model years but as of now our VIN is not included in the recall. I don't believe this is coincidence. I believe the mechanical issue is more widespread than Acura wants to reveal and is subsequently limiting the VIV numbers it includes. I am trying to be proactive in this regard prior to an incident taking place.

The contact owns a 2016 Acura MDX. The contact stated while driving at an undisclosed speed, the vehicle stalled. There was no warning light illuminated. The vehicle was towed to an independent mechanic, but the vehicle was not diagnosed or repaired. The vehicle was then towed to the dealer, but the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was not available.

The connecting rod and bearing failed, causing the engine to immediately seize while in full operation on the highway. Components are available. The engine rod catastrophically failed and shot through the oil pan. Engine seized and lost power while on highway, cruising at 75mph. Flying engine components and the immediately loss of power was a major safety risk. The car was towed to the dealer and they found the rod bearing had sheared off. American Honda has been sent pictures. My model and year were affected by a recall on the failed components but my VIN was not identified. The car had no warning lights on the dash and was been recently serviced.

The contact owns a 2016 Acura MDX. The contact stated that while driving at an undisclosed speed, the vehicle made a rattling sound with the check engine warning light illuminated. The vehicle failed to accelerate properly. The vehicle was taken to a nearby independent mechanic; however, the vehicle was not diagnosed. The vehicle was towed to a dealer, where it was diagnosed, and the contact was informed that there were metal shavings at the bottom of the oil pan. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact related the failure to Technical Service Bulletin: 23-036. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 108,500.

We have a 2016 Acura MDX and it has automatically shifted to Neutral 3 times (twice while driving on the freeway and 1x yesterday while driving on the street at normal speeds) in the last 2 months. On the MDX dashboard, it will display "Emissions System Problem" and then display "Stop Driving When Safe. Transmission Problem. See Manual." However, the car will automatically shift to Neutral within seconds. My children's lives (7 y/o and 5 y/o) were placed in danger as a result of this system failure. I have contacted the Acura Honda Recall Specialists and Client Relations Representatives. The car is being diagnosed at Cerritos Acura dealership at the present time. A case number has been filed since our VIN shows no recall, despite it having recalls for other 2016 Acura MDXs.

I was driving the car, when I saw a sign pop up on the dash saying " Emission Systems problem" and the car completely stopped within a 100 feet. The car passed the Emissions and Inspection the previous day and I have a registration till June 30, 2026 now. There was a clicking noise that I heard when driving during the morning. I had never heard it previously. There was an oil change sign for about 3-4 days buy there were no other warning lamps. Here is the video of the problem from the dealer - [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After traveling about on a 4 hour drive, my daughter who was driving the vehicle slowed down to make a turn. That's when she heard a loud clanking noise coming from the engine. She immediately pulled over and turned off the engine/vehicle. I went to meet her, and replicated the same problem when I turned the ignition switch to to on. It sounded as if there was some large piece of metal loose inside the engine -- it did not have consistency and was highly variable with regards to the sound it was making. The "Check Engine" light was on. Fortunately this did not occurr going at high/freeway speeds, yet the safety was compromised when my daughter was fortunate enough to leverage the momentum to get to the side of the road. Additionally, she was not in a spot where there was a shoulder/it was under an overpass, so she had to be careful and turned on her emergency lights. We had the vehicle towed to the nearby Honda Dealer. I am attaching their report and findings. They recommended engine be replaced; which we agreed to have done. Additionally, we continue to have problems due to the mounting and shacking which we believe comes from the installment of the new engine. We are submitting that report as well. At present, my daughter is not driving the vehicle and is relying on rides or borrowing other people's vehicles.

While driving our well-maintained 2016 Acura MDX on a 30-minute drive on [XXX] , I heard a pop, and then the engine lost power. I couldn't get the RPMs over 2500. A fluttering noise evolved into knocking and the vehicle became increasingly sluggish and heavy. The check engine light started blinking, but the vehicle's temperature gauge showed no changes. There wasn't any smoke or unusual smells. I felt terrified trying to get safely onto the side of the road with cars driving at full speed. I had the car dropped off at our local service station and the owner determined that the engine cylinder was loose and lost compression with a knock. He says that the engine light did not give a code. The owner determined that we need to replace the engine. A rebuilt engine will cost us $8,000. When I called Acura, the service person I spoke with seemed surprised that our 8-year-old car with only 77,000 miles needed a new engine. Since Acura has so many cars to deal with on the latest recall, he said it would be weeks before anyone can look at it. I researched and found that our VPN was NOT included in the recent recall of 2016-2020 model year MDX vehicles all with the same problems. How can that be????

I am writing to bring to your immediate attention a critical safety issue with my 2016 Acura MDX, and the subsequent exclusion of my vehicle from a known recall that directly addresses the problems we are experiencing. Without any prior warning, we began hearing a fluttering sound coming from the engine whenever we accelerated. This noise progressively worsened and evolved into a pronounced knocking noise.Concurrently, the vehicle became increasingly sluggish and heavy, resulting in significant difficulty when accelerating. Despite these alarming symptoms, the vehicle's temperature gauge showed no changes, there was no smoke or unusual smells, and the check engine light did not activate. Gravely concerned for our safety, we promptly took the vehicle to our local mechanic for a thorough inspection.The diagnosis revealed significant engine damage, specifically to the connecting rod bearings and the crankshaft. Given the severity of the issue, we then brought the vehicle to the closest Acura dealership, Pohanka Acura. The service advisor informed us of a recall affecting the engine and rod bearings in the 2016 Acura MDX model. They also confirmed that our vehicle's engine was indeed damaged due to the same rod bearings and crankshaft issue described in the recall. However, despite this clear evidence, we were informed that our vehicle's VIN was excluded from the recall repair. The technician who performed the diagnostic on our vehicle recommended a new short engine block, which is was concerning especially since it mirrors the known recall issue. I am requesting that the NHTSA urgently investigate this matter. I hope the NHTSA treats this issue with the utmost urgency and seriousness it warrants. The safety of Acura MDX owners is at stake, and immediate action is essential to prevent further incidents and ensure our safety. Thank you for your prompt attention to this critical matter. I await your swift response and resolution. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

Acura MDX 2016 SH-AWD with 113366 miles diagnosis according to warning lights. DTC test certification codes: P0301 Misfire No. 1 cylinder P0306 Misfire No. 6 cylinder P0300 Random Misfire P0420 Catalyst System efficiency below threshold B1 Recommendation was that the Catalytic converter be replaced. All these codes were identified under Honda's TSB 20-100 dated 2/2021 on Odyssey, Pilot and Ridgeline models where AH extended warranty to 10 years from date of purchase or 150K. These V6 engines are pretty close to that of the 2016 MDX. Is there a remote possibility that these DTC codes could exist in MDX V6 engines when an issue arises similar to those in the Honda vehicles? These DTC codes appeared 24 hours/37 miles after a routine oil service on 3/26/2024 at Advantage Acura of Naperville with a perfect inspection report. The malfunction occurred in the vicinity of McGrath Acura of Westmont on the following day of 3/27/2024. The concern is if any of the emission system components were damaged during the routine oil service. Advantage Acura have in the past installed brake pads backwards on my Acura TL 2010 for which I do have proof.

Engine rod bearing knocking. Will eventually fail and engine stop running at anytime. My independent service center did confirm the problem. The car has not been to the Dealer as they refuse to include my VIN # in the current recall for this very problem. No warning lights appeared, but slight ticking sound shortly turned into a loud knocking.

There is a current recall on Acura/Hondas with the issue that we are having with our car. Knocking engine, car diagnosed with connecting rod bearing issue. Apparently not included in recall. This makes no sense. Car has been undriveable since 11/9/23 with no help from Acura/Honda Corporate. We have been trying to come to a resolution with no help. This should fall under the recall and where our car was manufactured should be looked into because on car forums there are many cars with our VINS having the same issue. This issue has affected more cars than Acura is saying and needs to be looked into before someone gets seriously injured. Acura/Honda are NOT taking this seriously at ALL.

My 2016 Acura MDX, which was well maintained, locked up while driving at around 45 mph this past September. Upon a certified mechanics evaluation, it was reported that the vehicle would require a new engine as it was "locked up". Shortly afterward, I read that certain model/makes of Acura vehicles were being recalled for this very reason/problem. I called Acura recall client support who informed me that the final list of recalled vehicles would not be available until January 2024 and that I would receive a letter in the mail. When I did not receive a letter, I called again and was informed that my VIN was not included in the recall. This is despite that thousands of other 2016 Acura MDXs were recalled. I find it difficult to accept that a known issue that necessitated a substantial recall of vehicles did not apply to my Acura since it was the exact issue being addressed. Especially since the vehicle was maintained very well from the time of purchase. My teenage son was driving the vehicle and was stranded along a dark highway until I could pick him up about 45 minutes later. There were not warning lights or notices of this pending failure. The vehicle could only partially be removed from the traffic lane at the time it locked up which resulted in a hazard, not only for my son, but for other travelers as well.

The connecting rod bearing has failed in my vehicle. It is causing damage to the engine, there are metal shavings found in the oil, and the engine is producing a strange and unusual sound. It's causing the engine damage and wear and causing it to seize. The incident has been reported to the dealer and has been confirmed in an inspection report. There is a CURRENT recall from NHTSA and Honda/Acura for this exact issue that includes the same make, year and model of my vehicle, however when VIN numbers were split, my vehicle was not included in the recall. The recall should be expanded to not only include more vehicles but those that are actually being impacted.

WHILE DRIVING ON THE HIGHWAY THE ENGINE LOST POWER. THERE WAS NO WARNING.THE CAR BECAME INOPERABLE. THE SAFETY OF PASSENGERS AND OTHERS TRAVELING THE HIGHWAY WERE AT RISK. THE DEALER CONFIRMED THAT THE ENGINE FAILED AND ADVISED THAT THE ROD BEARING SPUN. THE VEHICLE IS AVAILABLE FOR INSPECTION AND IT IS UNKNOWN AS TO WHETHER THE MANUFACTURER INSPECTED THE VEHICLE.

The car suffer complete engine failure while driving on the highway. I had the car towed to an acura dealer . The acura dealer has informed me that the engine rod failed There is a recall by acura for 250,000 vehicles incuding the same year and model for the same problem . The engine is availble for inspection . My vehicle is not under recall . i was informed by Acura customer relatiins that they will not help me . I was informed by a acura dealer that they will can replace the engine with a used engine for 9000$ . i said ok but then wondered if the engine they would replace it with was under recall. The looked into it and have informed me that the engine is in fact one of the recalled engines and then asked me if i wanted to proceed with the replacement with an engine that is dangerous ... This seems incredible to me and should be illegal and certainly dangerous..

while driving on a local road (not highway), engine began to make a very loud sound. sounds like metal on metal inside engine. called local ACURA dealer and they said that the connecting rod recall/problem that was announced in November 2023 "does not apply to my VIN".

Ticking Sound in Engine Diagnosed by Dealer as same issue reported in recall for Year Make and Model of Vehicle. Diagnosed with need for engine replacement ($8,700). All service requirements by manufacturer done by dealer. Dealer says it is unsafe to drive. Vin not covered under recall NHTSA # 23V-751

My engine light enabled & my car slowed < 30 mph while driving on a frwy on 2/4/23. I exited & turned the engine off. It was late at night in a rural area, so I waited a bit & turned the car back on. Engine light was no longer on, so I continued to my destination (GA). On 2/5/23, while driving on the frwy, my engine light enabled & my car quickly slowed to < 20 mph. The light stayed on & my car had little power (limped along). After a few hours, there was no change & my car was not drivable. I got a hotel for the night & took my car to the nearest Honda dealer on 2/6/23. The service dept told me my car needed a new engine because the bearing or rod had gone bad (terminology may be slightly off). My car had UNDER 100K miles & I was told it needed a new engine. The Honda serviceman told me he had 3 other vehicles in house with the same issue & he wouldn’t be able to get to my car for a while. I called the nearest Acura dealer & spoke with a serviceman there, he told me to ask the Honda serviceman to clear engine code & slowly drive the car to the Acura dealership. The Honda serviceman warned me that my car may not make it to the Acura dealership but might if slowly. He cleared the code & I slowly drove to the Acura dealership. I reached the Acura dealership shortly before closing time on 2/6/23, I dropped my car off with the service dept & got a hotel room. I was contacted the following day, 2/7/23, by the Acura serviceman & he confirmed a new engine was required. There’s now a recall on the same issue my car experienced for same make, model & year, however Acura states my VIN was not affected. It is highly unlikely that my same make, model & year vehicle that experienced the exact issue for the recall is simply coincidence.

First on off glitching when ever accessory mode is used WHILE IN MOTION, FIRST BRAKELIGHT HAD WARNING THEN WARNING ABOUT TRAILER STABILITY ASSIST. WHEN I WENT IN REVERSE, THE WHOLE DASHBOARD INCLUDING THE NAVIGATION SCREEN WENT BLACK AND THE CAR FELT LIKE THE ENGINE STOPPED. THIS HAPPENED A FEW TIMES. I DON'T THINK THE ENGINE ACTUALLY STOPPED THOUGH BECAUSE I DID NOT HAVE TO RESTART THE CAR. THE BRAKE LIGHT ERROR MESSAGE HAS OCCURRED DRIVING FORWARD AS WELL, BUT NOT ACCOMPANIED BY THE BLACKOUT OF THE DASH AND NAV PANEL. Steering becane stiffer ALL OF THIS HAPPENED WHILE IN MOTION.

On a multi-day road trip, the car had a temporary complete loss of power on two separate days. Both times this happened after several hours of driving at highway speeds on I-15 in California, outside temperatures were in the 90s. After a slight deceleration and then applying the accelerator again, there was a 'clunk' like sound possibly from the transmission, and then a complete loss of power. The first time I tried to pull over to the breakdown lane, and then regained power after about 2-3 seconds. The second time, we were in the middle of traffic and were not able to pull over, but again after 2-3 seconds, the power came back. The engine did not rev up when applying the accelerator and there were no dashboard lights. This appeared to be either a transmission, fuel delivery, or engine management/drive by wire issue. While we luckily did not get into an accident, we did slow down significantly on the highway, requiring other drivers around us to break, or change lanes. I have made an appointment with my independent mechanic, but the car has not been inspected yet and I am not able to forcibly reproduce the issue.

This 2016 Acura MDX with the 9 speed automatic transmission and the Auto Engine Shut Off function will sometimes fail to restart the engine after cutting off. This presents a safety issue as the car stalls in traffic. This has happened multiple times over the last 4 years (most recently 06/02/2022). This issue was noted to the Acura service department who stated they could not find an issue.

when air conditioner is running in hot summer days, the car hesitates to restart (sometimes) following idle stop engine shutoff after coming to a full stop at a stop sign or red light. I strongly feel this is a safety concern as this impedes traffic and can causes road rage. If needed I can share video of this situation recurring time to time. Car starts just fine every single time outside of idle stop situations and battery health is near perfect. There are hundreds of forums talking about this exact condition across acura models.

Acura has an open recall that shows the symptoms or malfunctions my vehicle is having for my year, make, and model, but the vehicle I.D number doesn't show this type of recall for it. Now, these things do not add up give the malfunctions I'm experiencing. First and foremost, the car stalls, I could be on the NJ turnpike and as soon as traffic slows down car goes into neutral on its own and engine just shuts off in the middle of traffic, do not know when its going to happen, it just happens. Car then turns on once fully stopped and foot is on break but probably after another hour same thing and it is continuous. I have replaced a number of things and it is still malfunctioning. NHTSA Recall # 19V-060. No check engine light recorded since i bought the car and when running, car runs smoothly. It is preowned vehicle, called Acura and I was told that the fuel pump was replaced, but according to the recall it also needs a software update to fix the malfunction. At this point I just need help on taking the proper steps on getting this safety issue fixed.

The contact owns a 2016 Acura MDX. The contact stated while driving at various speeds, the vehicle would stall. The contact also stated that the vehicle would jerk when the accelerator pedal was depressed. The contact stated the information and engine warning lights were illuminated on the control panel. The vehicle was taken to a local dealer where it was diagnosed with the transmission needing to be updated. The vehicle was repaired but the failure still occurred. The contact was relating the failure to NHTSA campaign number: 19V060000 (Fuel System, Other). The manufacturer had been informed of the failure and the contact filed a claim. The failure mileage was approximately 41,000.

SINCE I WAS GOING OUT OF TOWN THE NEXT MORNING, I PUT IT IN REVERSE AND DROVE DIRECTLY TO THE DEALER. THE CAR WAS IN "LIMP MODE" AND I COULD ONLY DRIVE 35-40 MPH. I SHOWED THE TECH IN THE SERVICE DEPT. ALL THE WARNING LIGHTS GOING OFF, AND HE SAID HE HAD NEVER SEEN ANYTHING LIKE THIS BEFORE. HE WROTE UP A WORK ORDER WITH THE FOLLOWING INFO: INSPECT FOR CHECK ENGINE LIGHT ON, CHECK ENGINE LIGHT FLASHING AND EVERY WARNING LIGHT IN THE VEHICLE IS ON, WOULD NOT ACCELERATE OVER 35 MPH. THE FOLLOWING DAY I WAS CONTACTED BY THE SERVICE DEPT. AND WAS TOLD THEY COULD NOT FIND A PROBLEM; THERE WERE NO LIGHTS ON, THEY EVEN DROVE IT FOR 40 MILES. THE SERVICE DEPT. SAID THEY ARE ONLY ALLOWED TO HOLD THE CAR FOR FIVE DAYS. TODAY, 9/8/25 I PICKED UP THE CAR. THE DEALER'S INVOICE READS: CAUSE: LIGHT ON 123505 DIAGNOSTIC TROUBLE CODES/PROGRAMMED FUEL INJECTION (PGM-FI) RETRIEVE CODES WITH THE HDS, READ DATA, 74 WA3.

SINCE THE SERVICE DEPT. COULD NOT FIND THE PROBLEM AND FIX IT, THIS MEANS THE CAR HAS NOT BEEN REPAIRED AND I AM DRIVING A DEFECTIVE CAR. THE NEXT TIME THE WARNING LIGHTS GO ON, I COULD BE TRAVELLING ON A CROWDED FREEWAY AT A HIGH RATE OF SPEED (WITH MY FAMILY INSIDE), THE CAR GOES IN TO "LIMP MODE - 35 MPH AND AN ACCIDENT OCCURS. THIS IS A SAFETY ISSUE. HOW CAN ACURA MANUFACTURE A $50,000.00 CAR AND THEIR DEALERSHIP NOT BE ABLE TO FIND THE PROBLEM AND REPAIR IT?
