Brake vacuum pump failed at 112k miles while doing 60 on the highway with no warning or way to stop. Very dangerous. Service brake assist light only come on after the fact of brake pump failure. Shrapnel from the failed part was sent into the engine block that had to be professionally cleaned out. This happened again 4 months later when I had to replace the brake vacuum pump AGAIN. I almost wrecked and lost my life then as well since again, it happened out of nowhere while driving no warnings. Brake assist light only came on after. This is DEADLY and should be recalled and rectified by GM promptly before someone is killed.

The contact stated that while driving approximately 45 MPH and depressing the brake pedal to reduce speed, the vehicle failed to respond as intended and crashed into the rear end of a second vehicle at approximately 5 MPH.

Engine temp gauge stops working causing the air to stop working and the cooling fan to rev to highest rpm. Also a warning that the steering assist is reduced. Eng check light comes on with a code P0208. This a known problem with an extended service # (N242484760) but only if your vin is listed. All vehicles with this problem should be covered. This seem to be a common problem, as my co-worker is having the same issue. This should be a recall as the steering is affected.

GM has a known recall and special coverage N242454441 to cover the exact same issue I experienced on my way home from work. However, I am informed my model is not included in this special coverage. The issue I experienced while attempting to turn into my apartment complex on a busy road [XXX] my rear wheels locked up mid turn no warning signs, no lamps, no messages or other symptoms were present. Almost causing me to get into an accident had traffic not stopped. I was able to shift it into park and then to drive to immediately pull off to the side into a parking lot and put my OBD reader I have P0747 solenoid 1 failed locked on. I was informed by GM that they could attempt to reprogram the transmission control model, however based on research this is not the root cause of the issue it is due to the soft aluminum bores causing the transmission module to ware and fail. I have a service appointment on 6-12-26 at 10 am at Bill Cramer GM in Panama City, FL INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The truck started backfiring and shuddering. Took it to the mechanic and with only 112000 miles I am being told it needs a new engine. It is the 6.2l motor.

As I was driving 75 mph down the highway my collision alert flashed all my lights turned off, including my headlights and all interior lights as it was dark time and they flashed back on a couple of times until they finally stayed on. I pulled over and as I came to zero, speed, the vehicle completely shut down. It did start back up, but this is not the first time I get a light on my dash that says stability track and then everything resets and I don’t have any lights on at all after that this has been happening off and on I also have three coworkers that have the same make, and year that experienced the same problems ! My situation on the highway was very dangerous. It was pitched dark outside and I lost vision due to my lights going off at 75 mph and my steering wheel also locking up. The next time the vehicle does it I will take a video for proof. I have heard that this problem is very common in these vehicles and believe something should be done because that is a dangerous situation if I was going around a corner and my steering wheel locked up, I could easily flip my car. I have small children that’s why I have the big space but we need safety for our family.

While driving my 2021 Chevrolet Tahoe, the check engine light illuminated. Shortly thereafter, the engine began shaking severely and I heard clicking and popping noises from the engine compartment. The following morning, the vehicle was barely operable, shaking excessively and unable to properly reverse. Due to the unsafe condition, I had the vehicle towed to the dealership. The dealership diagnosed a failure involving all 8 lifters on one side (bank) of the engine, requiring extensive engine repairs. My vehicle has approximately 74,000 miles, which I believe is low mileage for such a significant internal engine failure. The symptoms included severe engine vibration, misfiring, loss of performance, and the potential for loss of power while driving. This is not the first major failure I have experienced with this vehicle. In approximately April 2023, when the vehicle had about 32,000 miles, it unexpectedly shut off while I was reversing in a roadway. The dealership diagnosed a failed fuel pump control module (fuel pump modulator). Similar failures were later identified in recalls and corrective actions affecting other GM vehicles. I am concerned that my vehicle has experienced multiple failures involving components that appear to be associated with known issues affecting GM vehicles, yet my Tahoe was not included in applicable recalls. These failures created significant safety concerns, including unexpected engine shutdown, loss of vehicle operation, and potential loss of power while driving. I respectfully request that NHTSA investigate whether my 2021 Chevrolet Tahoe vehicles should have been included in existing and future safety recalls related to these defects and other known defects that GM vehicles are experiencing with the motor, transmission and other parts. Note: No invoice is available yet as I am seeking GM assistance due to no warranty status. Estimated repair cost from dealership is up to $8,900.

I am writing to formally report a critical safety defect in the vehicle’s transmission system. While driving, the vehicle began experiencing severe vibrations, accompanied by an abnormal increase in engine RPMs, while the vehicle failed to accelerate appropriately. The vehicle became unresponsive, limiting my speed to 15-20 mph. This forced me to make frequent stops every 6-7 minutes to allow the transmission to cool down, as the car would not sustain normal speeds. ?This failure created an extremely dangerous situation on the highway. Due to the sudden loss of power and inability to maintain traffic flow, I was subjected to aggressive behavior from other drivers, who were honking, gesturing, and clearly endangered by my inability to accelerate. This transmission failure is a major safety hazard that renders the vehicle unreliable and dangerous to operate in any traffic condition. I am requesting an immediate investigation into this transmission defect and a permanent resolution from General Motors, as this issue poses a significant risk of causing a collision. I spoke with the owner of AAMCO, and he showed me that they have 7 of these Chevy Suburbans, GMC Yukons, and Chevy Tahoes, Escalades, and they all have the same problem, the transmission needs to be replaced, and General Motors is not notifying car owners about this problem, but it should.
