The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the forward collision, check engine, and traction control warning lights illuminated, and the messages "Forward Collision Unavailable," "Service Traction Control," and "Service ESC" displayed on the instrument panel. An abnormal muffler sound was heard, the engine compartment vibrated, and the vehicle failed to accelerate above 35 MPH. The vehicle was taken to the dealer, where the engine was disassembled and it was determined that the lifters failed and the engine required replacement. Prior to the failure, the vehicle was taken to the dealer for an illuminated check engine warning light and an engine knocking sound; however, the dealer only cleared the diagnostic trouble codes while the vehicle was under warranty. The manufacturer was notified of the failure by phone. The failure mileage was unknown.

2022 Chevy Tahoe went into limp mode at 62,500 miles out of the blue and check engine light came on. At the certified Chevy dealership I was told it was the transmission control valve, Code P2732, which is a known widespread factory issue in these models. Upon further inspection, was told my transmission fluid was completely black and burned and it ruined the transmission and therefore it needs to be replaced. "Consequential Damage Policy: When a control valve body fails and stays "stuck on," it forces maximum line pressure through the system. Continuing to drive under these conditions quickly destroys the internal clutch packs, burns the fluid, and melts down the transmission." This is exactly what happened and my vehicle was never put on a recall list but clearly was a ticking time bomb.

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)

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.

My 2022 Chevrolet Tahoe has a recurring pattern of excessive oil consumption, smoke from the exhaust, repeated check engine light events, P0420 catalyst-efficiency faults, and repeated catalytic-converter-related repairs. At approximately 75,000 miles, the vehicle shut down on the freeway. At approximately 121,000 miles, the first catalytic converter failed. Chevrolet of Wesley Chapel documented P0420 and catalyst failure in November 2025, and GM service history reflects catalytic-converter replacements at 131,468 miles and approximately 141,082 miles. The vehicle also underwent major injector-related repair in early 2026. At 141,620 miles, Chevrolet of Wesley Chapel started an oil consumption test and stated in writing that oil consumption can lead to repeat failed converters and false oxygen sensor readings. Despite substantial repairs, the problem pattern continued. I am reporting this as a possible safety-related defect affecting engine operation, emissions-system failure, and drivability, and I am asking the federal safety agency to review whether this indicates a broader safety-related defect.

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.

During a normal acceleration from an on-Ramp onto a major interstate a Check Engine Light (CEL) came on with warnings of safety features no longer being active. The vehicle begin vibrating abnormally and the pedal was not very responsive. I took the next exit and stopped at an auto parts store to have the engine code checked. Cylinder #2 misfired due to an injector issue. The vehicle was confirmed to have this issue at a Chevrolet dealership. The car was a CPO through FORD and was covered. I owned the vehicle for 14 days. This unit has the L87 Motor, and had already undergone a motor replacement under the recall warranty. The injectors apparently were not replaced, only the O-Ring. Unlike many manufacturers GM has removed Fuel Injectors from their PowerTrain warranty. A motor with under 5,000 miles was not covered since the body and bolt-ons were original with 45,000 miles. GM has a very recent history of injector recalls and issues. These injectors should undergo the same scrutiny as previous GM injectors.

2022 Tahoe RST with 5.3 10 Speed. Bought new in Sept of 2021. The 2022 we have had problems with shuttering in the drivetrain from very low miles. We have brought it into the dealership atleast 3-4 times before for this issue. This was all while it was still under its 60k drivetrain warranty. Dealership always told us that since there was no check engine light or codes that they can’t fix what is not broke or broke yet. We needed to wait for it to break or light then bring it in. We also received a letter in the mail for the trans recall (program)last year which was preformed. That day after, my wife started to notice it shuttering more than usual and more often. I call the dealership that performed the recall which they said to bring it in. After looking it over. I get a call saying that I should get the transfer case fluid, front and rear diff fluid changed. It might be the transfer case slipping. Advisor told me that since it was about due for this service. Fast forward to May 9th of this year. My wife was at church. She parked it which it ran fine. Came out about 30-40 mins later put it into drive and wheels where locked up. She called me panicking that something was wrong. Go to her aid which I had to have it towed to the same dealership that serviced it before. Even check it in with the same advisor that helped us before after the recall issue. I should now mention our 22 Tahoe has 68,700 miles. Dealership called us a few days later saying it was the valve body. Especially since we had have problems before with the drivetrain and documented. The vehicle is still inoperable. We are waiting for a valve body with no ETA.
