2023 Chevrolet Tahoe

We had car checked due to strange and erratic shifting in less than a year of owning. Then took in for recall, they stated it was fine and performed the remedy with higher grade oil. Still had issues and took to another dealership to look at and they stated it was fine as well. About 2 months later while I was driving it was hesitating and would kind of buck and when I was about to turn on to a busy road it just stopped. I couldn’t do anything at all, the entire car was locked up. The tow truck driver couldn’t even get it into neutral to tow. Dealership said it’s the engine and it needs to be completely replaced.

Space does not allow for a complete statement. However, here is a summary. I purchased my 2023 Tahoe on 07/19/23. On 07/27/23, the check engine light came on. Since then, there have been approximately 8-9 instances where the check on. Each time I took the vehicle in for service, however, the check engine light kept coming back on. There have been 2 instances in 2026 where the vehicle would not start, and then the check engine light came on. A Chevrolet dealer service advisor told me that this is a known issue with GM and Chevrolet; however, no remedy has been found yet.

Following a GM-initiated over-the-air (OTA) software update on May 18, 2026, my vehicle's windshield wipers became permanently inoperable — stuck in the "on" position with no ability to turn them off. This is not a gradual mechanical failure or wear-and-tear issue. The malfunction began immediately and directly as a result of a software update pushed by General Motors. Because the wipers cannot be controlled, I have been forced to remove the wiper fuse to make the vehicle driveable. This means I am currently operating a vehicle without functional windshield wipers — a federally mandated safety system. I want to be clear: this unsafe condition was caused entirely by a GM software update, not by any action or negligence on my part.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving at 40 MPH, a warning message advising to reduce acceleration was displayed, the Check Engine warning light illuminated, and the vehicle stalled. The contact was able to pull over safely. The contact stated that the failure was recurrent. The dealer was notified of the failure and diagnosed the vehicle with a valve failure. No further information was available. The manufacturer was notified of the failure. The failure mileage was approximately 57,000.

It has not been inspected yet but will call the dealer tomorrow morning since I just this vehicle on Friday

Total engine failure.

While traveling at 55mph yesterday, I experienced a full engine failure which shut the car off fully while traveling on a single lane double yellow road. I was able to coast to a secure location. The car will not start or go into neutral. There were no warning lights that occurred at any time prior to the failure. This all occurred while on vacation 2 hours away. I previously went to the dealership for the recommended "fix" for the recall but that obviously did not solve the problem. This was an extremely unsafe situation for me and my family. I also encountered towing costs and significant loss of time. In addition, the car is at a dealership over 2 hours from my home. Chevrolet should be held accountable well beyond a recall notice which didnt solve the problem.

Chevy Tahoe with 6.2 V-8 engine started making noise. Started rattling. Taken to dealership where I bought it. Oil changed found metal in the oil engine making all sorts of noise. Diagnosed to engine failure. New engine is ordered . It’s been 2 weeks and I am number 5 In order for engine replacement at the dealership

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving at 75 MPH, the vehicle shut off without warning. Due to the failure, the contact used excessive force to steer the vehicle off to the shoulder of the highway where the vehicle was then towed to a dealer. After the vehicle remained in the dealer's possession for over a week, the vehicle was diagnosed with an engine failure. The contact was then informed that the vehicle was placed under recall NHTSA Campaign Number: 25V274000 (Engine) and that the engine would be replaced. Despite the engine repair, the contact stated that an abnormal, rattling sound would emit from the vehicle upon start of the engine. In addition, the contact stated that the vehicle would violently jerk upon depression of the accelerator pedal while at a complete stop. The failure started intermittently; however, the contact stated that overtime the failure became more persistent. The vehicle was taken to the dealer where they claimed that the transmission was four quarts low on transmission fluid; they then informed the contact that they could not guarantee that remedy would repair the failure. The contact stated that failure improved; however, she would still experience a slight hesitation upon depression of the accelerator pedal. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 39,000.

Two years in a row my car leaked a significant amount of water through every light button any hole in the ceiling. It also leaked all over the center counsel while driving and came through the foot pedals all over my feet and the entire floor of the vehicle while driving. The value of my car has been destroyed and Chevrolet is not taking this seriously. They have told me they will only replace the roof liner and half the carpet. They are not acknowledging the potential damage done to the electrical system and the overall value of the car from bad smells that have been caused by dirty water soaking the entire interior. My car is ruined and it should be replaced.

Oil consumption- 1-3 qts low between oil change intervals at 5000k No burning or oil smoke.

Engine stopped while driving 70 mph down the highway and the car shifted into neutral. Had to cost to side of the road. Took car into dealership and even though the car was certified safe drive and the engine had no issues 5 months ago, I was told the engine was now locking up. The engine failed despite using the higher viscosity oil that chevy recommended. These greedy cunts at chevy placed me and my family's lives in danger to save a buck; they knew that the engines would fail and instead of replacing the engines, they put thicker oil in the cars to hopefully get the cars past warranty.

The car has cut off three time while at stoplights. I can get it restarted but the dealership cannot duplicate it even though there are codes in the system. Also the automatic braking will randomly stop when it shouldn’t and it is a hard braking.

Transmission has had a failure to shift problem on several occasions resulting in deceleration and a decreased ability to accelerate. This has occurred on most occasions at highway speeds while passing a vehicle causing a very unsafe condition. Dealer has evaluated and determined the transmission valve body is defective and needs replaced. Upon researching the problem, many similar GM vehicles are experiencing the same issue

The engine randomly shut off while driving down the interstate and wouldn’t start back up. The car had the recall “remedy” done to it. Inspection and thicker oil. The only warning I got was to restart the engine after it shut off. My safety was compromised by breaking down on a main interstate coming through Memphis with no emergency lane to pull over in.

2023 Tahoe Z71 had recently been put in the shop, and evaluated for engine failure recall. Dealership/GM deemed it failed test for replacement, we were given 0W40 oil and sent back out, this last weekend we had catastrophic engine failure while operating at 50+MPH.

On April 10th, while traveling approximately 7 hours from home on a very busy highway in [XXX] , my 2023 Chevrolet Tahoe (6.2L engine) suffered a complete and catastrophic engine failure, requiring a full engine replacement. The vehicle had to be towed and I was left stranded with no transportation. Prior to this failure, I had brought the vehicle to an authorized GM dealership for a recall inspection specifically related to the 6.2L engine on September 9, 2025 with 36,162 miles. The dealership technician inspected the vehicle and informed me that my engine was not defective and cleared it. Shortly after that inspection, the engine suffered a total failure at 46,6xx miles on the vehicle. I am currently leasing this vehicle at approximately $1,100 per month and have been without the vehicle for an extended period while it sits awaiting repair. GM customer care has been contracted and has indicated they cannot move forward with a buyback claim because the BBB is not taking my case because the vehicle is older then 2 years old which I know is a false legal claim. This is a serious safety concern, a catastrophic engine failure at highway speed poses significant risk to vehicle occupants and others on the road which appears consistent with other reported failures. I am aware that NHTSA has opened Recall Query RQ26001 investigating the adequacy of GM's remedy under recall 25V-274. My experience is consistent with the 36+ complaints that triggered this investigation, engine failure occurring after an authorized dealer performed the recall inspection and cleared the vehicle. I am requesting this complaint be added to the RQ26001 investigation file. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

As I was driving down the tollway in Dallas going 75 miles an hour, my engine completely shut down and went into neutral in rush hour traffic. I had to slowly get over from being in the left lane as my car was slowing and slowing. I was able to get over on the side of the tollway as cars zoomed past me. By the grace of God, I didn't get hit. Once it was towed, the service department confirmed that it is my engine that shut down and the entire engine needs to be replaced. Now the problem is they cannot find an engine or parts to fix it. No warning came on at all before this happened. Very dangerous situation.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The oil was changed at the local dealer. After 24 hours, the engine was blown after driving approximately 50 miles. No warning lights were illuminated. While accelerating from a stoplight, there was an abnormal squealing noise from the drivebelt. The vehicle was taken back to the local dealer, and the contact was informed that the flywheel was hitting the camshaft and changing the oil had disturbed the function of the vehicle. The vehicle was not fully diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 14,945.
