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.

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.

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.

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.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation.
