2021 CHEVROLET TAHOE Complaints

I was driving along the highway at 11pm when I the vehicle started shaking and I heard strange sounds coming from outside the vehicle. I pulled over to inspect and realized it was coming from the engine bay. The engine was making knocking, rattling, and belt slipping noises and the entire vehicle was shaking and the engine also stuttering. I was able to drive the vehicle to a nearby plaza where I had it towed the following morning. There were no warning signs, the vehicle ran properly up until this occurred. The dealership inspected it and told me the engine needs to be replaced and it was likely that a rod bearing that went bad. This happened nearly 2 months ago and I am still waiting for a new engine.

Fuel Pump Module Failure at 27k miles, experienced total loss of power while driving. GM issued a recall for this part in other 2021 Tahoes, but said my vehicle is not included in the recall. Researching online this seems to be a large problem with this model year, yet they did not recall all vehicles. Clearly mine was effected.

I want to file a complaint on Chevy I have a high country, 2021, my dealership has had it for over 2 months, can't get the part to fix it - valve body- They have another one there, that's been there for 5 months, can't get the part. So, 2 Tahoes at same dealership, same problem, and can't get the part to fix. I have escalated to chevy, have a case number, chevy themselves can't get the part to fix my truck. But I still have to pay for it-big payment for something, I can't drive, isn't worth anything for trade and useless- I am furious. I have been a lifetime chevy owner-and this is changing my mind.

My vehichle will not go in reverse my wheels are locking up and also my car is going over 6000 rpm when going down the highway and not wanting to shift gears where it is a safety concern for myself and my kids well being

I'm [XXX] so not much night driving. The other night I left a meeting when I turned on headlights one is pointing down. Difficult to see and hard to stay between the lines. My vehicle has never ben in an accident nor had lights repaired. Checking online I see this is a problem for many Tahoe, Suburban and Yukon owners and perhaps even pickup trucks. In my opinion this represents a serious safety concern. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After I washed my 2021 Chevrolet Tahoe, I went to run some errands. As I pushed the start button, the car would try to start but did not. I tried several times without success. I had the truck towed to Ed Morse Chevrolet in Sunrise, Florida. My odometer is at approximately 43,000 miles. About 3-4 months ago, at 42,000 miles, I had the same situation. I had to have the truck towed to Ed Morse. At the time, the Service Writer told me it was probably the fuel cell module and that Chevy has been a problem with them. The Service Writer surprisingly admitted that this issue could cause the truck to stop in the middle of your commute! I told him that an issue this serious needs a recall. So, today, when AAA picked up my truck, he said that this happens frequently and he towed many Chevrolet Tahoes and pickup trucks with this issue. The AAA technician even reiterated that the fuel cell modular failure shuts down your vehicle while driving! This is insane and troubling. Within 1000 miles, I will need 2 fuel cell modules and there is no guarantee that this one will last.

2 incidents of complete engine power loss while driving. Luckily was able to roll off road safely to curb. Dashboard glitch/flashing multiple/various message, including check engine, conditions not ideal to shift, etc. Would not re-start/shift when attempted. Tried disconnecting battery cable completely and re-connecting and that seemed to 're-set' the system and engine re-started. Incidents were about 30 days apart. "This battery reset" was tried because approx 1 year prior after leaving Tahoe parked at airport for a 7 day trip, it would not start, completely dead. Battery charge/jump would not work...watched youtube videos and someone said to try disconnect/reconnect cable and it worked to start it up at that time & did take it into Dealership after that incident and no-cost repairs were made for that issue. Called Chevy 3/25/25 on this power loss while driving issue to ask for information/assistance, they advised to take to dealership for diagnostic info/report and depending on result/cause might assist with costs to repairs. Appointment set for 3/28/2025 with Salem Oregon Chevrolet.

Transmission control module failed. I was driving at about 40 mph on a 4 lane street and it begin to feel like something was pulling the steering wheel to the left and I could not control the speed. I then pulled off into a parking lot and was facing a drainage ditch and needed to back the car into a space out of the way, it would not go into reverse. My husband met with me and was able to drive it forward to drive it to a dealership. The diagnosis was a failed transmission control module that cost us $2,478.

The contact owns a 2021 Chevrolet Tahoe. The contact stated while driving at an undisclosed speed at night, the contact became aware that the headlamps failed to provide adequate illumination. After a visual inspection, the contact observed that the headlamps were loose within the assembly and were dramatically tilted at a downward angle. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The vehicle was taken to an independent mechanic, who diagnosed a failure with the headlamp adjuster. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 60,000.

Driving on a highway to Dallas and vehicle loss power and locked up in the middle of the highway.Was stranded on the highway for 4 hours. Vehicle would not start up and had to get towed to local dealership. Dealership diagnose the problem and stated that the engine has failed. I got the vehicle towed back home to my local dealership and they confirmed that the engine has failed. The vehicle showed no signs of engine issues. GM needs to recall this vehicle.
