The check engine light came on on my Chevy Tahoe, November 2023. The system started to fail it would say for collision not able service ESC system. I would bring it into the shop. They would hook it up to the computer and they would say oh nothing wrong we just reset it. Then it started to shut down and it would say proceed with caution, low acceleration, no front and collision service ESC and I would have. Luckily I was in a city so I took it to the shop. They gave me a print off. Said there was no technician cleared it. I was able to make it home and I made an appointment. They put it on the computer. they said oh nothing‘s wrong. Everything‘s fine then it did it again and I was going through the mountains. I noticed that my car smelled of gas and that the gas gauge was just sucking fuel and I knew this was a problem.. they finally found out what was going on, but I feel the damage had already been done. The part that got replaced was over $1000. I had to pay out-of-pocket for it. Now my vehicle’s engine is shot.

Failed coolant control valve and months-long wait for replacement part. Error code P1098. Service center informs us that the parts shortage is nation-wide. We must frequently monitor the engine temperature, which distracts from attentive driving.

The vehicle has a safety recall stating the vehicle has been affected and the engine could fail during operation and loose propulsion with an increase risk for a crash. There are not any precautions in place or offered neither is there any part available to repair the vehicle in the near future. The vehicle is a 2022 Tahoe with 60,000 miles and still under the manufactures extended warranty and they have no solution to offer any remedy at this time.

Check engine light with P1098 code for engine coolant control valve failure. This part has been on back order for months and manufacturer hasn’t declared a recall or provide any update to their customers.

Vehicle went into neutral while driving down the road, when trying to shift it back into drive a warning came up on the dash stating, "CONDITION NOT CORRECT FOR SHIFT" and the check engine light came on as the car shut off.

DURAMAX ENGINE - Coolant Control Valve malfunctioned on the Diesel Engine. Can Not Drive my 2022 Tahoe. In the Dealership for 2 Months now and waiting.

On May 9th, 2025 we had to have our 2022 Tahoe towed to the local dealership. There was a transmission error message and the battery was completely drained. The dealer put a new battery in it for $485 and we were told it was good to go. The next day, the car would not go into Reverse. Had to have it towed back to the dealership and was told that the Transmission failure was a recalled part and would be covered. Later we were called and told even though the part that had failed is in fact the same part in the open recall, that our VIN was not on the recall list and the cost to fix the vehicle would not be covered. In addition to all the headaches and money out of pocket (rental cars, tows, new battery) we now have to wait at least 4 - 6 weeks to receive the recalled part but since our VIN is not on the 2022 Tahoe recall list (even though it is the same part as the recall that failed), we are having to pay out of pocket for the repairs. Chevy needs to stand behind this recall and cover the cost.

Dear. My name is [XXX] . Phone # [XXX] . My email: [XXX] On [XXX] my Tahoe suddenly shut off while I was driving over 70 mph on the highway. It was towed to the South pointe chevrolet dealership in tulsa. I was told a fuse had failed and paid nearly $400. On April 17, 2025 they returned my Tahoe and said it fixed. [XXX] When i tried to start engine, then it acted like something almost can't start, then i text dealership and told them situation. On [XXX], the same failure occurred again — again at highway speed — nearly causing an accident with an 18-wheeler. The Tahoe was towed a second time. 2 times i was able to re-start engine drive until i stop then can't start it agian. Both time i smell something burned when i tried to re-start it. On April 21, I texted the service manager about GM TSB N252494000, which describes propulsion loss involving the L87 engine — the same engine in my Tahoe. Two days later, I was sent an invoice for $865.30 for a starter replacement. I was told the repair would not be covered under warranty — despite the vehicle still being under 60,000 miles at the time and the defect appearing to fall under a known GM issue. This is a recurring, life-threatening failure that GM and its dealer have not fixed. The vehicle is still under warranty, yet GM is refusing to cover the repairs.

Driving my Tahoe (67,000 miles) down the highway and everything is perfectly fine, suddenly all of the check engine lights began to flash. I wasn’t sure if it was an electrical glitch or not until the engine started knocking loudly. I was on a bridge in traffic and had no where to safely pull over. I had to drive a few miles further just to get to safety at which point the knocking became extremely loud and the entire car began shaking. I had the vehicle towed to the dealership where they informed me the lifters had gone out as well as the cam shaft. Apparently this is a very common occurrence among owners of this vehicle/similar vehicle. I am so grateful this is the one time my two small babies were not with me. It was a very scary situation and I was hours from home. This came completely out of no where without warning. Of course this happened 7,000 miles out of warranty. So now after paying over $70,000 for a vehicle that is barely 3 years old and only driven in town for the majority of that, I was stranded and now going to be out $10,000 to repair.

While driving from Boise, Idaho to Jackson, Wyoming our 2022 Tahoe 6.2L with 70K miles shut down at 85MPH on Highway 84 outside of Pocatello. Luckily, my wife was able to coast off the exit. We had the Tahoe towed to the Dealer and advised it would be 4 months for a new engine as our order was number 4,000 in line for an engine. Luckily, all of a sudden engines arrived from the supplier and was replaced in 3-4 weeks. Tariffs must have sped up the process. Downside, I paid 50% as we were out of warranty and GM would not cover the entire cost. Now I see the recall and would expect to be re-imbursed. We will see.

At 22,000 miles on the Interstate highway, vehicle suddenly lost all power, no throttle, went into neutral and we were lucky to be able pull it off to the shoulder without an accident. It had stalled and after multiple tries we were able to restart it. Then the check engine light came on and we drove it directly to dealer. There was a code for camshaft sensor and we were told all lifters needed to be replaced. Upon doing so, they found metal pieces in the engine and said entire engine needed to be replaced. The engine was on back order for up to several months. We waited a month then decided to trade due to loss of vehicle use. Dealer was very helpful during repair but no assistance from GM for a known issue on the 6.2L that could have had a negative outcome on the highway. This was not only a safety issue but a very expensive situation to trade out of for an almost new car.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that upon starting the vehicle, there was an abnormal knocking sound coming from the engine compartment. Upon acceleration, the RPMs rose significantly, and the vehicle hesitated while accelerating.

There was no warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed, and the contact was advised that the failure was likely related to NHTSA Campaign Number: 25V274000 (Engine). The part needed for the recall repair was not yet available. The vehicle was not repaired. The manufacturer was not made aware of the issue. The approximate failure mileage was 60,000.

Purchased brand new. Had for awhile and the veh shook. Took it in and the replaced with all brand new lifters. Still not correct than replaced with all new fuel injectors. Now when I take it in for the last several months it’s 1.5 to 2 quarts low on oil. Told that GM standard says 1.5 quarts low between oil changes is normal!!! I’m currently on an oil consumption test at each 1,000 miles snd I’m at 2 qrts with 1,500 til my next oil change. The volume on the radio goes up and the computer is stuck and you cannot turn the radio off or use the computer screen at all. You have to turn off the vehicle and start it again in order for the buttons to work.

At 30,534 miles, and still under warranty (5.3L V8) I had a complete engine failure without warning. Catastrophic and immediate engine failure. Latest word was a cam and lifter problem on a vehicle still under warranty. Repair time stated at 1-3 months. Engine failure occurred on a business trip en route to Dallas, TX in rural Oklahoma. Paid $275 for towining, $115 for a hotel and $360 for a rental car. Zero compensation.

On 2/27/25, I was driving down the highway and the dash stated "push start for engine" and began to lose all power. The engine seized with no other warning. I was able to safely pull over to the side of road and was then towed to the shop. This vehicle has been serviced on a regular basis. It was found that the engine had blown and am still waiting for a replacement.

3 Separate Major Problems: 03/23 - 8500 miles. Driving at 70mph on highway, received message on drivers display "Conditions Not Correct For Shift", car went into Neutral, no acceleration possible. Was able to safely get off highway. Stopped car, and restarted, error went away and car was able to be driven further without incident. Chose to not take in for service, 4/23 - 9000 miles. Noticed fluttering noise coming from engine bay when lifting off gas after acceleration. Service eventually found lifter/bearing issue. Whole engine was replaced under warranty. Was without car for 3 months. Further research online found that others experienced the same issue while driving and had engine failure at speed resulting in life threatening driving conditions. 4/25 - 31000 miles. Last weekend, driving at highway speeds and came to traffic standstill in left lane on major highway. Went to accelerate, and received "Conditions Not Correct for Shift" message, car went into Neutral and would not accelerate. Turned car off, and tried to restart and car was stuck in Park. No way to access Neutral, leading to blocking of left lane where cars were approaching and avoiding us at highway speeds. OnStar was notified immediately with the severity of danger stressed (2 adults, 2 children and dog remained buckled in the vehicle). However, CHP took over 1 hour to arrive, shut down highway and somehow was able to start the car one time and get into Neutral for CHP to push car safely to shoulder. Dealership alerted me to failed "Fuel Control Module" To have to 3 major engine related incidents that could have lead to accident or death is unacceptable. Online research shows these issues have been common for this vehicle engine and is absolutely unacceptable. For a driver to not be able to safely engage a Neutral override is absolutely unacceptable. I was informed by the tow truck driver that a special tool was needed and you had to crawl under the vehicle to engage neutral override.

Driving the Tahoe to work. All sudden motor started cutting out and died. Vehicle was towed to Chevy dealer. Was notified by them engine was locked up and needed to be replaced. 6.2 Motor

While driving on the highway the engine started to makes noise and shut down in seconds without warning- we glided down an off-ramp narrowly avoiding oncoming traffic and was towed away on the ramp - the engine only has 68,000 miles and it well maintained. It’s my understanding that the NHTSA is investigating problems with the 6.2 L engines on 2022 Tahoes that have sudden lost of power please add my name to the investigation- GM has refused to help I’m hoping that a recall which is warranted will help with the $11,869 cost to replace the engine.

Vehicle suddenly lost power at 70mph in heavy traffic. This was after a very brief flash of the electrical system off and then back on. Vehicle was safely pulled to the side of the road (luckily). The electrical system kept demanding to “push start” and then would shut off and then immediately come back on, but without the engine starting. The vehicle would not completely turn off, or turn back on from that point forward, killing the battery in the process. We called Onstar, who had it towed to Bill Estes Chevrolet in Carmel Indiana. Mark in the service department then informed us that the engine was completely seized up and would require an engine replacement.

While driving down the highway, the vehicle suddenly experienced multiple issues. The headlights went out, the vehicle would not continue to accelerate, and all interior lights shut off. The vehicle then shifted into neutral and stalled. There were no warning signs or indicators before this happened. Our safety was at risk as we barely managed to pull the vehicle over to the shoulder, with no working emergency lights. The highway had no street lights, and we were constantly worried about being hit by other cars since our vehicle was nearly invisible without the emergency lights. The malfunction left us stranded more than two hours from home. We had to have the vehicle towed to a Chevrolet dealership for inspection, which was also over two hours away. Prior to the failure, there were no warning lamps, messages, or other symptoms—everything happened suddenly without any notice.

I’ve done some research on the Chevy Tahoe 6.2L engine failures my Tahoe experienced the same thing our Tahoe just shut off in the middle of rush hour. 2 days ago we’ve started hearing slight knocking on higher RPMs and sometimes just idling and also would have a rough idle but it would go away with no check engine lights or warnings on the dash till today we haven’t taken it to the dealership to look at do to it having 61k miles just past its warranty and us not having the finances to get the truck fixed.

ENGINE QUIT RUNNING UNEXPECTEDLY, WITHOUT WARNING, AS WE WERE DRIVING DOWN THE FREEWAY ABOUT 30 MINUTES FROM OUR HOME. FORTUNATELY, WE WERE ABLE TO GET OFF TO THE SIDE OF THE ROAD BUT FACED DIFFICULTY IN GETTING THE VEHICLE ON THE TOW TRUCK. NO POWER SO ELECTRONIC PARKING BRAKE WOULD NOT DISENGAGE FOR MORE THAN A FEW SECONDS. PLUS THE REAR WHEELS WOULD NOT TURN AT ALL. WE DID GET FINALLY GET THE VEHICLE TOWED TO A NEARBY MECHANIC WHO INFORMED US THAT THE ENGINE HAD SIEZED AND WOULD HAVE TO BE COMPLETELY REPLACED WITH A BRAND NEW ENGINE. SUSPECTED MAIN BEARING FAILURE. I HAVE READ THAT YOU ARE INVESTIGATING PROBLEMS WITH THIS ENGINE, GM L87 6.2L V8. SINCE OUR VEHICLE HAS 75000 MILES AND IS OUT OF WARRANTY WE ARE FACING REPAIR CHARGES OF UP TO $15000 TO $20000. WE COULD USE A LITTLE JUSTICE. THANK YOU.

[XXX]. We dropped our vehicle off at Chevrolet on old Seward after our engine seized while on the highway. We had to exit the highway with our five children inside. We had it towed to Chevrolet for them to fix in which the car was finally ready for pick up [XXX]. Not to mention when GM sent the tow truck, it couldn’t even tow our vehicle. They had to order another tow truck because the manual override for the parking break wouldn’t release so I had to sit in the feeezing cold WITH MY KIDS for over an hour. #3 MAIN CAP SEIZED CAUSING ENGINE TO NOT TURN OVER AND ROD SEIZED AS WELL.

Driving on interstate (I55 - traveling South bound, Bridge over water) traveling at 70 MPH engine started to make loud noise and car was shuttering. We were able to take the immediate next exit. After taking the exit, within minute or two, the car/engine shut off with no way of restarting or steering. The engine did start to smoke when the hood was popped to inspect. Tow truck was called to transport us to the local Chevy dealer in Hammond LA - Ross Downing Chevrolet. Since it was a Saturday, we had to wait for the dealership to reopen on Monday. On Monday, I was called and told that there was indeed complete engine failure, and later in the day it was determined that it was due to a rod bearing issue. GM was contacted since I was 3,000 miles outside of my warranty, and the agreed to cover roughly $17,000 of the repair to completely replace the engine. I was out of pocket $3,227.56. All oil changes and maintenance were on time and kept up with. Just had an oil change roughly a week earlier before the engine failure. There were no lights that came on the dashboard even after the vehicle completely failed.

While driving under normal conditions, the 6.2L engine in our 2022 Chevy Tahoe seized and stopped running. We were lucky that it was early in the morning and without a lot of traffic and were able to coast the vehicle safely off of the road. Upon inspection from the dealership, they indicated that the engine experienced catastrophic failure. The dealership replaced the engine, Battery, Starter, Fuse box, and steering gear. We were lucky as the failure occurred just prior to us getting onto the interstate. Prior to the failure, there were no warning lights or issues with the vehicle. It was a sudden and catastrophic failure.

While driving 70mph on the interstate, my 2022 Tahoe stopped accelerating, the engine seized, and shifted in to neutral at 52,000. I was able to coast to the side of an extremely busy interstate, right before a bridge and wait for assistance. The dealer confirmed this is a problem known to this vehicle. The engine is on backorder, even under warranty. They say an SPAC has been filed and I had to make a claim to GM to reimburse them for the starter, battery block, and battery they decided to replace first. They said it could take up to 3 months to receive a new engine and there was a waitlist for a 10day loaner car. The vehicle had just been at the dealer for a 50,000 mile check up and warranty repair. There were no other symptoms prior to this catastrophic engine failure.

Exhaust system failure. Was told by manufacturer vehicle dealer service center that cause of the failure was not from normal use or misuse but due to manufacturing and weak metal/poor materials. No warning lights or messages ever appeared on vehicle information system. First report of exhaust smell in vehicle cabin on 4/9/24 at 38,874 miles. Vehicle dealer service center tested for leaks and found no leak. Second report of exhaust smell in vehicle cabin on 8/6/24 at 48,106 miles. Vehicle dealer service center tested for leaks and found no leak. Third report on exhaust smell in cabin on 10/31/24 to service manager who confirmed he could smell the exhaust in vehicle cabin. Car went to shop on 11/5/24 at 55,077 miles. Two exhaust leaks detected. From dealer: "Smoke tested exhaust system and checked for leaks, found a hole in the exhuast pipe right before the muffler and is likely the source of the smell." Additionally from dealer, after first repair: "After exhaust repair the vehicle was started and heard and audible exhaust leak on the drivers side. After further inspection found the drivers side exhaust manifold is leaking as well." I have been driving this vehicle for at least seven months with exhaust leaks and with exhaust coming into the cabin of my vehicle exposing myself and passengers to carbon monoxide. Reported twice to dealer and they reported no issues.

While driving the car, going 50 miles an hour down the highway the car slowly comes to a stop goes in the park and stops in the middle of the road. Wouldn’t go into any gear for me to get the vehicle out of the roadway kept flashing message about going into low power mode And vehicle had to be towed to the dealer

Our family of 5 (including 2 children and an infant) was driving 70 mph westbound on Interstate 40 east of Knoxville, TN when our 2022 Tahoe RST engine seized. For a few seconds, we had no steering, braking or acceleration and the dashboard began flashing. After a few seconds, the car shifted itself into the neural gear and we were able to brake on the shoulder of a busy highway. We were unable to restart the car. We called the police as well as AAA. The police came and sat behind us to deter oncoming cars to changes lanes. AAA came and towed our car to Reeder Chevrolet dealership in Knoxville, TN. There, it was determined that our engine had seized and needs to be replaced under warranty However, there is a backorder on the engine, and we are now driving a rental car. There are several other Tahoes in their service department with similar circumstances in need of a 6.2L ecotech V8 engine. There was no warning at all that the car had problems. Up until this point, there were no issues. I believe there is a widespread problem with these particular engines and this should be addressed on a national level. Our lives were at risk.

Lifters ticking Fuel Injector misfires

Car started ticking and loosing power Exited and car stalled and car towed to nearest dealer Capital Chevrolet in Montgomery Al. It has been there since 5-26-23. They first told us engine crankshaft blown, then said they will repair but parts on back order and no estimated EPA. GM customer service has been involved but no help.

Tahoe will not start nor will it allow to be jumped by another vechicle. Tahoe is kept in garage this is the 4th time this has happened. Dealer replaced the battery first time saying that was the culprit, second time they could not find a root cause, and same for third time. I see this is a common problem with engine, battery and electrical of the 2022 tahoe. I do not feel safe in it knowing this could cut off on me driving down the interstate.

On June 1st, I was put in a very dangerous situation while driving on the highway. Out of nowhere, my vehicle’s engine started clicking and immediately converted to a rough in the middle of highway traffic. I was terribly afraid from my life. I was headed to Duluth, GA for a meeting but had turn around and drive 31 miles back in rush hour traffic to Steve Reyman Chevrolet Dealership, in cobb county in this condition. I was extremely stressed; afraid that i could potentially be injured in an accident or fire, because of the engine. Several never before seen warning signals appeared. These signals included Service ESC, Service Traction Control, Forward Collision System Unavailable and the check engine light. I had just had my truck serviced on 5/26, as the dealership had been monitoring the oil consumption of my 2022 Tahoe. By the time, I arrived to the dealership, the service department was closed, so the vehicle was left overnight. I met with the service advisor in the morning and was told there was a cylinder 4 misfire and that a fuel injector and spark plugs was needed. After picking up, my vehicle on June 12th, the issued was not resolved and my vehicle was inoperable. I regularly service my vehicle including recommended service, so I’m not sure how something this extreme could happen. Looking back at my service records, there have been several occurrences where the vehicle stalled out and the dealer blamed the auto/start stop feature or a failed battery. All pretty ridiculous claims for a brand new truck. I’m convinced this vehicle was produced poorly. My truck has 72,325 miles on it, however I came across several forums with new body Tahoes & Suburbans with way less mileage (i.e. 4300 miles) that experienced the exact same issue. Attached, you will find all the times, I brought my vehicle in for service for a major concerning issue.

Driving on highway and car started making a loud noise and it completely stopped, had to tow to the dealer.

Will coming to a stop the vehicle would just stall. Didn’t notice the dash saying to restart and as let off of break the truck started to roll backwards almost hit car behind me. Did this about 7 more times. Made appointment with dealership and they told me there was no problem found.

With 8500 miles while driving the engine started ticking, jerks on acceleration, Trans shifting very slow and a light warning with “reduced acceleration while driving” came on. Then immediately after the Instrument panels warning lights indicated service traction control, forward collision system unavailable, and check engine light all illuminated. Then car stopped accelerating and was almost rear ended on highway. Luckily no one was hurt. What is GM/Chevy doing to fix this issue. Apparently, this is common issue with the new Tahoes.

While driving, I heard a ticking noise, that sounded like rocks being thrown in the fender well. The more I drove, the sound and frequency increased. Then, I started to lose power, like it was taking longer to shift. My safety and others were at risk because continuing to drive with lifter issues could’ve caused engine failure, which could’ve caused an accident. The problem was confirmed at a dealership. I don’t know if anyone else inspected it. No lights appeared until after I had it towed to the dealership. They said the warning lights came on for them.
