The headlight adjustment screws fail causing the projector adjustment to bottom out leaving limited visibility when driving in the dark. The headlights then do not raise back up any longer.
Engine and engine cooling, Power train, Apr 30, 2025
The contact owns a 2021 Chevrolet Tahoe. The contact stated that while her husband was driving at an undisclosed speed, several unknown warning lights illuminated, and the engine made knocking sounds. The message "Service Transmission" was displayed. The contact's husband pulled over and turned off the vehicle. The vehicle failed to restart immediately. The vehicle was taken to the dealer, who replaced the camshaft retainer, valve tensioner kit, gaskets, seals, lifters, engine bolts, rods, and pipes; however, the "Service Transmission" message displayed again while driving. The dealer was made aware of the failure, but the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 89,678.
Power train, Apr 30, 2025
My vehicle has a little over 15000 miles on it. On Thursday April 3rd, while driving 35 mph in town, my RPMs shot up to 4 and the vehicle would not respond to accelleration. A few seconds later the engine light appeared. I managed to get the vehicle home going no faster than 42 mph off and on. Upon arriving home I realized I had no reverse in the vehicle. I immediately called the dealership and was told to bring it in. They didn't look at it until the following Monday April 7th when they determined the Transmission Control Module went out. GM told them they "couldn't find that part anywhere". Thr vehicle still sits behind the dealership and GM has no answers and has already hinted that it may be at least 60 days. This is unacceptable.
Engine, Apr 30, 2025
Sudden engine failure while driving. Was able to pull to the side of the road with a few hundred feet. Repair required full engine replacement. Have to other friends that drive similar gm products that also experience engine failure with 3 weeks of our incident.
Engine, Apr 27, 2025
Engine burning through oil excessively. Has been noted on multiple occasions and requires early changes and top off. Is also happening with 3 friends with the same make and model with the 6.2L. No warnings but was informed it is common at shop.
Engine, Forward collision avoidance, Apr 27, 2025
We had a failed lifter that caused bent rods which caused scratches on the crank shaft which caused us to have to replace the engine. After a simple internet search I have found the lifter failure is very common with gms 5.3 v8. We were told oil needs to be changed at least every 5000 miles although the vehicle prompts you around 7000.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving 15 MPH, the vehicle lost automotive power and stalled.

Engine, Apr 10, 2025
Traction control light came on and the vehicle felt like it was going to die/low idle. I took to dealership on 9/13/22 (5months after getting vehicle) and the codes P03000 00 which is an engine misfire, P050D 00 which is cold start rough idle and it was noted by service tech that engine making a clunk and ticking noise. There was a misfire on cylinder 6. They removed the valve cover and the intake valve rocker arm was not moving at all and when the rocker arm was removed they noticed the push rod was also bent. They verified the DFM lifter was collapsed.
Fuel/propulsion system, Apr 3, 2025
I was driving the vehicle, exiting the parking lot when the engine and all electrical components turned off. This could have easily caused and accident as there were multiple vehicles that had to go around me while I tried to restart the vehicle. The engine would crank but not start up and left me stranded in the middle of the road AND in the middle of two lanes. When I finally got the vehicle towed several days later (which was not easy because in order to put the transmission in neutral without the engine being on, a special tool is needed) I took it to the dealership. They confirmed it was the fuel controller that went bad for the second time. The first time the vehicle was stuck in my garage at home with the same symptoms. They apparently replaced it with another faulty part that is a ticking time bomb. I have no faith that this won't happen again.
Power train, Engine, Apr 3, 2025
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/propulsion system, Apr 2, 2025
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.

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.

Engine, Mar 5, 2025
Approximately 4/14/24 while I was driving home from being out of town with my child the check engine light came on with a message “Reduced acceleration drive with care.” The car was not shifting and I couldn’t go over 45 mph and the rpm’s were about 3000 at that speed. The light went off and the car seemed to be driving normally. While on the interstate traveling at approximately 70 mph the car did a hard shift and drastically slowed while the rpm’s spiked. I took it to the dealership who determined the valve body needed to be replaced. Approximately August 2024 it happened again but the light went off. December 2024 same issues with the check engine light, reduced acceleration and not shifting happened. Took the car back 12/9/24 where a wire was replaced. Picked the car up 12/12/24 and 12/18/24 while driving in the car rider line picking my child up the car had a hard shift, check engine light came on, reduced acceleration message and the car would not shift. Notified the dealership immediately and took it back 12/26/24 where they did a second valve body replacement. 1/28/25 on my way home from running errands and was stopped at a red light and the car shifted hard, check engine light came on, reduced acceleration message and engine would not shift causing me to drive slowly to get home (40 mph or less). Dealership was notified immediately and took in the following day. Dealership had a week and had me pick it up because they “couldn’t replicate the issue.” 2/15/25 after driving 2 hours we pulled in a parking lot and the car shifted hard hard, check engine light came on, reduced acceleration and would not go into reverse. The dealership picked the car up and have had it since trying to replicate it. It occurs without warning while driving and will drastically slows the car down putting us a risk of being rear ended due to the rapid and speed change. It also is a safety risk due to lack of warning that a power failure is about to occur while driving.
