Driving the vehicle down the highway at approximately 65 miles per hour, the check engine light came on and the engine went into limp mode, slowing immediately. Upon getting the vehicle to the left shoulder on a busy highway, the vehicle displayed "engine overheating", "battery low", and 0% oil life. A full oil and filter change had been done less than 1000 miles ago and upon checking the oil, it was at the correct level. The engine completely failed and is not being replaced at a Chevrolet dealership. I completed the recall N252494003 on March 5th, 2026 which comprised of an engine inspection, higher viscosity oil, a new oil cap, filter replacement, and owner's manual insert. The engine still failed and required replacement despite having this done.

I am writing to formally report a critical safety defect regarding the OnStar Telematics Control Module in my 2022 Chevrolet Tahoe High Country VIN: [XXX] . My vehicle was recently diagnosed by SERRA CHEVROLET as having a failed module, which has rendered numerous essential features inoperative. This is not an isolated incident; there is clear evidence of a widespread failure affecting thousands of GM and Chevrolet owners. The failure of this module creates significant safety risks, including: * Loss of Emergency Services: The OnStar SOS button and automatic crash response are disabled, leaving me without a lifeline in the event of an accident. * Systemic Vehicle Malfunctions: This module is deeply integrated into the vehicle’s architecture. Its failure has caused [list your specific issues, e.g., "Check Engine" lights, heads-up display failure, and battery drainage]. * Disabled Connectivity: Core features I paid a premium for, such as navigation, remote start, and Wi-Fi, are now "bricked". It is unacceptable that a flagship $80,000+ vehicle is operating in a degraded and potentially dangerous state due to a known hardware defect. I am requesting that GM take immediate responsibility for this repair at no cost to me, regardless of warranty status, as this is a fundamental safety issue. Please provide a timeline on how GM intends to rectify this widespread defect. I look forward to your prompt response. Sincerely, [XXX] [XXX] 39,000 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle has suffered a Transmission Control Valve Failure (stuck open). This is the exact mechanical failure detailed in GM’s Nationwide Recall N24245441-02. It is deeply disheartening and illogical that my vehicle—which shares the exact year, make, model, and identical mechanical failure detailed in the safety bulletin—is excluded from the recall purely due to an arbitrary VIN filtering process

After a rain fall a "swooshing" sound is heard above, water will pour through the overhead lights where the onstar is, the seatbelts and the back interior lights. The drain tubes to the sunroof have been cleared and the problem still persist. When the water comes in the buttons start blinking and it causes a risk to the person driving when they are distracted by the water pouring in and the water pooling under your feet possibly causing your foot to slip while driving.

My 2022 Chevrolet Tahoe diesel unexpectedly lost power while driving. I was stopped, made a right turn, and accelerated to approximately 34–40 mph on a two-way street when the vehicle suddenly shook, shifted into neutral, and the engine shut off without warning. There were no warning lights, dashboard messages, or prior symptoms before the failure. I was driving with two young children secured in car seats at the time. This created a serious safety risk because the vehicle became disabled in the roadway, and I had limited control while traffic was present. The vehicle has not yet been diagnosed, and the exact failed component/system is unknown. The vehicle is available for inspection upon request. The incident has been reported to a dealer or service center, but the problem has not yet been confirmed or reproduced at this time.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at various speeds, the check engine warning light was flashing, and the vehicle was shuddering. The vehicle was taken to the dealer several times, and it was diagnosed with a misfire in cylinder #5. The dealer informed the contact that the engine was taken apart during the diagnostic process, and the vehicle was repaired; however, the contact expressed doubts that the engine was taken apart or repaired because the dealer had only sent pictures of the exterior of the vehicle to the warranty company. Additionally, the failure recurred while driving. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 85,000.
