Description of the safety problem On XXX, shortly after starting the vehicle and beginning to drive, I attempted to apply the brakes and discovered that they had essentially frozen up and were not functioning properly. At the same time the vehicle displayed the following warnings: Service ESC, ABS warning light, brake system warning light, "Trailer Brakes Disabled – Service Required," traction/stability control warning, and check engine light. I shut the vehicle off and restarted it. After the restart the brakes appeared to function normally again and most warning indicators disappeared. However, the check engine light remains illuminated, and I have noticed a slight hesitation when starting the vehicle. I have photographs of the warnings taken at approximately 21,029 miles. Relevant history This vehicle was purchased new. The original 6.2L engine suffered a catastrophic failure at approximately 18,685 miles while traveling at highway speed and was replaced under warranty. None of the current problems existed before that engine replacement. Since the replacement, the vehicle has experienced multiple electrical failures, including windshield wipers becoming inoperative while driving in rain, intermittent loss of electrical power and starting problems, steering-related and collision-system warnings, and tire-pressure warning discrepancies. During a recent dealership visit to Ourisman Chevrolet (service advisor [XXX]) for multiple electrical malfunctions, I was told the problem was simply that the battery needed to be charged. The problems have continued, culminating in the XXX braking malfunction. Request I am reporting this as a potential safety defect affecting the braking, stability control, and electrical systems of this vehicle, and I request that the federal safety agency record and review this complaint.

Vehicle is a 2021 Chevrolet Tahoe Premier with under 50,000 miles. The vehicle experienced a sudden and complete loss of reverse gear, accompanied by violent lurching, sputtering, and dangerous hesitation/stuttering while accelerating between gears at speed. A certified dealership inspection physically diagnosed the vehicle with multiple stuck valves inside the transmission control valve body, requiring a complete valve body replacement. This exact mechanical failure completely mirrors the known safety defects outlined in GM Special Coverage Program N242454441, which details transmission pressure losses causing gear engagement conflicts and potential rear-wheel lock-up hazards. The replacement transmission component installed by the certified dealer failed catastrophically within four miles of pickup, again causing severe transmission sputtering and shifting failures that render the vehicle entirely unroadworthy and a safety hazard on public roads. The dealership has been forced to order an entirely new replacement valve body assembly under warranty due to a consecutive failure. General Motors Corporate Customer Assistance acknowledged that the vehicle is physically experiencing this transmission valve defect, but refused a voluntary warranty override solely because the vehicle's automated database VIN block falls just outside their pre-programmed list for Special Coverage N242454441. The corporate case representative explicitly instructed the consumer to file this federal safety report with the federal safety agency due to the systemic component failure.

The automatic transmission on my 2021 Chevrolet Tahoe (gasoline engine, 10-speed 10L80 transmission) has been exhibiting intermittent slipping/skipping during gear changes, particularly during acceleration and deceleration. The transmission component is available for inspection upon request. The malfunction poses a safety risk as the unexpected hesitation and rough shifting creates unpredictable vehicle behavior at highway speeds and during merging, increasing the risk of a collision with other vehicles. The problem has not yet been formally confirmed by a dealer or independent service center, however a knowledgeable automotive advisor has assessed the likely cause as moisture contamination of the transmission fluid, which degrades lubrication and causes erratic shifting behavior, known issue in several GM vehicles, but the only recall related to this issue is for just Diesel vehicles. I contacted General Motors customer service regarding this issue and was directed to file this complaint with the federal safety agency, as GM stated they were unable to attach or create a related existing recall to my vehicle. The vehicle has not been inspected by police, insurance representatives, or the manufacturer at this time. I am in the process of scheduling service at a transmission specialist. No warning lamps or dashboard messages appeared prior to or during the shifting malfunction. Symptoms first became noticeable at 85,000 miles, and have continued since.

I purchased my vehicle new in 2020. It presently has around 83,000 miles. From early on, it has occasionally hesitated, then jumped when putting the car in reverse. I spoke to the dealership years ago but they said it was nothing. On July 19, 2026, my car randomly would not shift above (probably) second gear on the highway. After parking, it would not shift into reverse at all. The vehicle was towed more than 30 miles to my hometown dealership as it was inoperable. It now requires something approaching a transmission replacement costing between $2500-4500, or more. I am aware that this is a recurring problem with GM vehicles of this type and era, and it seems absurd to have so many vehicles with failing transmissions before they even reach 100,000 miles.

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.

On June 17th, 2025 while driving from [XXX] back to my home state of [XXX] , I experienced an engine malfunction in Chester, Va where the 6.2 L87 engine was shaking and had severe hesitation. It was diagnosed by the Chevrolet dealership in Chester, VA as suffering severe failure of ALL 8 fuel injectors, fuel rails and connector harnesses, resulting in a 15 day repair wait and a $4,644.50 bill not including other expenses such as lodging/car rental. At this time my vehicle had 52,182 miles. After this I attempted for 3 months for GM to cover the repair as the vehicle was less than 5 years old and less than 60,000 miles under the 5 yr/60K warranty but denied it. On March 26th, 2026 while driving on the parkway at about 60 mph, my vehicle experienced loss of power (slow deceleration, shaking/hesitation) and I immediately took it to the repair shop where it was diagnosed as a P0308 code (misfire on cylinder 8) which caused a repair of the #8 spark plug, ignition coil and wire resulting in a $380. repair. Two days later, I experienced the same issue and then took it to an engine diagnostic specialty shop where I have been told that this issue will run about $4,000 due to valve and comprehension issues on an engine that has 60, 680 miles. I have seen numerous L87 engine complaints on Chevy Forums with no assurances that repairs or engine replacement will rectify the issue and feel that this is an issue that GM should be addressing for safety issues and an economic loss to its customers. I am hoping that your investigators can help the many people that have been left stranded by this incompetence and lack of admission of GM's part. Repair invoices available upon request.
