2021 Chevrolet Tahoe Suspension Problems

I purchased my vehicle new in 2020. It presently has around 83,000 miles. From early on, it has occasionally hesitated, then jumped when putting the car in reverse. I spoke to the dealership years ago but they said it was nothing. On July 19, 2026, my car randomly would not shift above (probably) second gear on the highway. After parking, it would not shift into reverse at all. The vehicle was towed more than 30 miles to my hometown dealership as it was inoperable. It now requires something approaching a transmission replacement costing between $2500-4500, or more. I am aware that this is a recurring problem with GM vehicles of this type and era, and it seems absurd to have so many vehicles with failing transmissions before they even reach 100,000 miles.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while turning left or right, there was a grinding and scratching sound coming from underneath the front-end of the vehicle. The vehicle was taken to the dealer to be diagnosed and the contact was informed that the wheel was rubbing against the wheel well. The dealer completed a tire adjustment. The contact noticed over time that the tread on the front tires had been wearing very quickly. The vehicle was returned to the dealer who determined that the lower control arms had failed. The lower control arms were replaced, and the front wheels were re-aligned. The failure persisted causing the contact to have the wheels aligned 6 to 8 times. The manufacturer was made aware of the failure. The approximate failure mileage was 32,000.

I’ve been dealing with an alignment issue since last June when I took in my 2021 Tahoe z71 with air ride suspension. It’s chewed up the stock tires at just 25,000 miles. It’s came out of alignment 3-4 times since then and Chevrolet is doing nothing about it. I’ve spoke with others that have the same vehicle and the same problem. I just purchased tires for $1,100 just over a month ago and I checked the alignment last week and it was out again after City Chevrolet fixed it on January 17th of 23.

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.
