2021 CHEVROLET TAHOE Complaints

I have has this vehicle for just over a year, and in the time i have accumulated 8,600 miles. Suddenly, yesterday after normal I stopped for a red light. The start/stop function came on (normally) and then all of a sudden the vehicle restarted it self, but, it started running rough, and misfiring. when i moved it backfired several time. I had to have the car flat bedded to the dealer, and apparently it has a known issue, with the lifters and the push rods. The dealer stated it will take a while to get the parts. h as 5 others in the shop for the same problem. My comment is, I am lucky this happened at a stop, I think this would be a major issue if this was to happened at 65 MPH ? You could end up in an accident while you deal with the issue.

While driving on a residential street during daylight hours, on a clear day at approximately 20 miles per hour the right wheel on my car dislodged.  This caused me to lose control of steering the vehicle and strike a parked car.  There were people walking about on the sidewalk at the time and other cars traveling.  When I exited the car I saw that the passenger side was completely on the ground and there were broken pieces and liquid coming from underneath the car.  The axel was broken with a clean break.  The car was then towed to the dealership where I was informed it could not stay.  My insurance company then towed it to their repair shop where upon assessing the damage they could tell that this was not caused by a collision.  General Motors along with our independent investigator examined the parts and vehicle. Leaving me without a vehicle for 4 months.  Our Insurance investigator determined this was a defect in manufacturing and GM did not agree.  General Motors will not communicate with us any further on this matter.  Some of the repairs that were made was the left front and CV axel, also the left front aluminum steering knuckle was missing.  This should be investigated for metallurgical discrepancies by an independent lab.  While the car was being inspected there was a recall to the power steering that may apply to the vehicle.  I would like for the NHTSA to investigate this issue.  The car has been repaired and is in my possession and my insurance company has all of the reports, documents, and parts regarding the investigation.  I also have pictures immediately following and a witness to the incident. Had a been traveling on a highway at a higher rate of speed this could have been fatal.  Your assistance in this matter would be greatly appreciated.

On 10/21/2021 while driving about 65 mph on highway 80 in Sacramento my sunroof glass exploded. It was not struck by any object. The weather at the time was rain and about 60 degrees. Traffic was light and nothing near that could have caused this to happen. Fortunately the shade was closed preventing any glass to enter the interior. Its been in at the dealer Stevens Creek Chevrolet in San Jose since 10/21/2021 waiting for a replacement glass. This incident could have injured anyone in the vehicle if the shade had not been drawn. So far it appears it is being handled as a warranty issue.

Traction control and forward collision warning lights stared to go crazy in August 2021 (3800 miles), five months after buying my Tahoe. Sales rep indicated his new 2021 Silverado did the same and he was able to get it to reset by turning off and restating his engine. So I did the same and thought my issue may have resolved itself. Yesterday, the warning lights started to go haywire again (6700 miles) This time my vehicle felt as though it was going to stall and was making a clicking noise under the hood. The warning lights continue to flash regardless of how many times I turn on and off the engine. The engine also revs loudly.

Valve lifter damaged. Caused poor engine performance and lack of acceleration. Vehicle at dealer, who is very aware of this issue with GM V8 engines. Replacement parts on multi-week back-order. Check engine and other warning lights appear, as well as audible noises from engine compartment. Symptoms appeared on 10/8/21. 9,000 on vehicle

I purchased a 2021 Chevy Tahoe from Autonation Chevrolet 11-3-2020. I have taken my Tahoe to the service department numerous times - as my truck has had a stubborn service safety restraint system warning error code that continues to come on and off. I have taken it to have all recalls serviced as per recall request. The service safety restraint system warning code has not been corrected after more than 5-6 visits if not more as not all visits have been logged properly. I have had this truck for less than 12 months and have experienced too many conflicting issues. I do NOT feel safe driving my Tahoe with the SRS light on. There's obviously a malfunction that you all have not been able to figure out. This is extremely dangerous!! What if I were to get involved in an accident or collision and my airbags do not deploy? I may have a problem with the airbags themselves, a loose wire, a faulty seat belt buckle, or a problem with the engine control unit which is causing the airbag warning to come on. There is obviously a major problem. I am putting my children and family at risk. I have not received an email or phone call from anyone at Autonation Chevrolet. The service safety restraint system warning code has come on and off 7x since I was last at the dealership (9/10/21) and I have pictures to support.

2021 CHEVROLET TAHOE. CONSUMERSTATED THAT THE THIRD ROW SEATS HEADREST DOES NOT STAY ON POSITION. THE CONSUMER STATED THE GRAPHICS ON THE VEHICLE WERE NOT CLEAR. THE DEALER WAS NOTIFIED AND AKNOWLEDGED THE FAILURE. THE CONSUMER REFERENCED RECALLS N212338110 AND N212333900.

The contact owns a 2021 Chevrolet Tahoe. The contact stated while driving approximately 45-50 MPH, the vehicle stalled with the check engine warning light flashing. The vehicle was towed to the contact's residence. The vehicle was then towed to the local dealer but was not diagnosed or repaired. The manufacturer was notified of the failure however, no further assistance was provided. The failure mileage was 14,170.

In late May, 2021, an "over-the-air" software update was forced onto our vehicle by GM. This update was initiated, and resulted in a failure of the over-the-air system. We brought our vehicle in to our dealer, who indicated that the "module" is bad and a part is required to fix it. This part is reportedly "on backorder" with no known ETA. This has resulted in various notifications (turn signal indicators, and unknown other notifications on the dash) as well as our center console (music, nav, etc.) to become unresponsive. Since the "module" failure, GM has issued two additional safety recalls. In the paper notices we received for the safety recalls, GM indicates that they had been "prompting owners through the vehicle's radio screen" for a month, via this over-the air system, of which, ours has not been functional since late May 2021. The last of which is a power steering recall, which may result if loss of power steering functionality. Due to our inability to know the recall existed, resulting from the faulty "over-the-air" system, my family took a trip through the mountains only to return home to this recall notice. GM has been unresponsive in repairing the system used to notify us safety hazards related to the vehicle that we have purchased, beyond noting that they are trying to "get the part as soon as possible". No one has been able to indicate what this "part" actually is, to date. The possibility of this module failure, and our non-functioning module, presents a serious safety hazard to drivers with this technology who are not made aware of recalls and other safety concerns which may result in crashes and serious injury or death.

The engine started knocking and running rough. My wife pulled the car over. She could tell from the sound it was not a minor issue. We had the 2021 Tahoe toed to Vaden Chevrolet in Beaufort, SC, where we purchased the vehicle. The dealer confirmed it was an engine problem. 8 lifters along with other associated parts need to be replace. This is a major engine repair. The vehicle is 8 months old and has approximately 10,000 miles on it. Doing internet search, the failure of engine lifters in Tahoes and Silverados appears to be a known problem. The service department manager told me that they have already done 10 of these this year. Failure of an engine while driving is a major safety issue. The vehicle is in for repair, now.
