2020 ACURA TLX Engine Problems

Recall performed on 2020 Acura TLX 3.5 for rod bearing recall. Crankshaft and bearings were replaced. 24000 miles later, the engine spun a bearing again with all the new internals. All maintenance records were supplied when the car was brought in. Acura is wanting me to pay 40% of the cost for a short block.

49,622 mark on my 2020 Acura tlx AWD… auto stop was enabled, car was at stoplight, engine attempted to re-engage but did not and car went into “neutral”… and the lights stayed on. I immediately turned on blinkers to avoid crash and and attempted to re start car, I shifted into Park, shut down car and re-started it successfully. I am seeking repair or disablement of the auto stop system, this is a safety hazard to myself and my family as well as others who had to go around while the issue was being troubleshooted. This appears to be related to Investigation:EA25004

On or about October 21–22, 2025, I brought my 2020 Acura TLX (brown, 99,000 miles, VIN [XXX] ) to Goodson Acura of Dallas for a recall repair related to engine concerns. The vehicle was returned to me on October 24, 2025. Shortly afterward, the car began to lag and hesitate while accelerating. On November 3, 2025, while driving to a doctor’s appointment on the Bypass Bridge in morning traffic, the vehicle suddenly stalled and lost power completely. This created a dangerous situation in active traffic. I recently underwent surgery following a serious burn injury, so limited mobility made this stall especially hazardous. After restarting the engine, multiple ADAS and system-fault warnings appeared. I contacted Goodson Acura and was advised to bring the vehicle in. Upon arrival, the service advisor confirmed the warning lights but required a $205 diagnostic fee despite the recall work. Acura Client Relations opened Case No. XXX and advised the charge should not apply if related to the recall. After waiting several hours, I was told the battery had died and that front camera/ADAS systems were returning codes. This stall occurred less than two weeks after recall repair and could easily have caused a serious crash or injury. I am requesting a full investigation into the recall repair, the stalling issue, and any related safety defects.

The recall impacting my fuel injection has not been fixed since 2023 i have been waiting. I was told parts are available now and would be called by someone but that has been more than a month ago.

the engine failed and lost all power to the car. It is available for inspection. My safety was put at risk because if i was going on a freeway and freeway speeds i probably would have crash and potentially crash into other people, causing a huge safety issue. The problem has been confirmed by dealer. They said it is very possible the engine rod bearing could have caused this. This is being inspected by Acura. Prior to failed there were no warning lamps or indicators. They all turned on once the car died.

I've received the recall notice for my car about 2 years ago. I've tried to schedule time with the dealership to get it fixed but they just keep telling me they don't have the parts or I have to wait till something "bad" happens first for them to prioritize me. This seems really unsafe and bad practice. I've reached out to Honda and they have open a case to review this but has not gotten back to me since. The car has stall once and a few times during the engine shut off while stopping, it takes a moment for the engine to come back, not normally like when I got the car. There has been a few time that there were cracking noise while I was driving. I stop driving the car as much as I can to avoid an accident happening. Please help me get some resolution with Honda, it's been almost 2 years.

I purchased a new Acura TLX in 2020. The following year it took it into get state inspected in Massachusetts. My care failed for emission 3 times. I brought it back to the dealer (Herb Connolly) in Framingham Massachusetts. They kept it for 3 weeks, worked on it and told me it was all set. The following year I brought it in for a state inspection. The same thing happened. They told me that they had seen a few of these cases. They found a way to get them to pass. They have to drive it at different speeds for a few hundred miles. I asked that they fix in properly and they noted that they did not have a fix. This was all after I picked it up. I told them I was concerned as I worried this could keep happening. They encouraged me to call Honda Motor Corp. I spoke to them several times and they denied the problem. I am not in my third year. Car is still under warranty and it again failed inspection. Below is an email from the service manager on how to get it to pass. From: Michael Brooks <[email protected]> Sent: Wednesday, July 26, 2023 4:05:38 PM To: [XXX] Subject: Passing Inspection Hi [XXX], As discussed we have not received any updated procedures or available software updates to get these cars to store the memory for the readiness flags. This is an issue what we have had to drive the car in very specific patterns to get it to pass. The main thing we do is DO NOT SHUT THE CAR OFF AFTER DRIVING IT JUST PULL IT INTO THE INSPECTION BAY AND LEAVE IT RUNNING DURING THE INSPECTION. There are a few flags that are notoriously tricky to get to flip. Usually we use our $20 “obd” tool that we got off amazon which monitors the flags in real time so we know when it is ready for inspection. Below are the driving patterns we follow to get the problem flags to turn over: O2 sensor This is one of the trickiest ones, we seem to have the most luck getting this one from continued driving so there is not a spec INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(

Software update completed June 2022 When coming to a stop light, my car shutdown. Went into neutral and took about five seconds to restart. It happened the following day and I was rear ended. No injuries occurred.

After coming to a stop at a red light, the vehicle engine turned off as designed with auto start stop. When the light turned green, the vehicle temporarily restarted when I released the brake pedal, but immediately stalled and would not restart. This is a major safety concern as I was on a four lane road with traffic all around and I was unable to move. I had place the vehicle into park, turn off the ignition fully, and attempt to restart the car. It eventually restarted, but it took nearly 90 seconds. This is a danger to myself, and to the traffic around me as I was fully stopped on a road with 40 MPH limits and a lot of traffic.

Car loses power on inclines. Stepping on gas and car decreases speed.

Two times in three weeks with the auto idle stop active the car failed to restart on a green light. Following all the prompts in the car it takes over a minute to re start the car while blocking traffic.

I was driving around 30miles/hr and the engines shut off unexpectedly. I was stuck in the middle of a highway and the engine didn’t turn back on. The dashboard showed total failure. The car was one year old with 11k miles. I just had it serviced by the dealer.
