• 12/22/2025· EXTERIOR LIGHTING

  As many have already complained, the headlight adjuster screw for the drivers side of the headlights of the vehicle always break or get stripped out even at low mileage, causing the headlight of the drivers side to point down onto the road and being unable to illuminate anything past the very front of the vehicle at night. This is a serious hazard that is not possible to fix or adjust without a large bill at the dealership. The drivers side headlight is pointed down and me myself, has resorted to adjusting the passenger side headlight to point up to compensate for this issue. This is causing many safety issues as I cannot see anything past 1-2 feet from the front.

  2021 Tahoe Z71 with 70000 miles making a roaring and whining noise on reverse and turning, especially when cold. Took to shop and they changed the rear differential fluid. Now its worse. Needs a whole new rear end. This veicle is 4 years old and does not tow or use four wheel drive. The shop said there has been so many complaints and services on the same issue.

It was stuck in Park, the electronic Parking Brake could not be disengaged, the door locks could not be operated and left unlocked, no lights, no warning lights, the emergency lights did not function, no horn, and most everything else. The only things still working were the radio, the driver's side powered seat would move, and the light came on for the Parking Brake. The battery was fully charged. I also started receiving messages through my Chevrolet APP that the vehicle had no air in the tires, no oil in the engine, and many other items that needed servicing. I am not sure what exact components or computers have failed yet. GM could not find any dealer to render aid and come to my location to reprogram the vehicle. It had to be towed to a dealer. With the electronic Parking Brake engaged, GM had a hard time trying to find a tow truck that wouldn't just drag the vehicle down my driveway and onto a flatbed.

  On November 9th, 2022 my wife was returning from the store when our Tahoe lost power and the engine shut off. She was able to pull off the highway onto a side street prior to the engine shutting off. I met her at that spot to see what was going on with the vehicle. The car was parked on a slight hill and after checking the oil and other fluids I could not see an issue with the car and the car would still not start. I was able to tow the car to a flat spot and checked the fluids again. After about 45 minutes the car did restart with the check engine light on. We were able to get the vehicle to an auto shop about a 1/4 mile down the road where they were able to hook up their reader and see what the check engine light was for. A code of P129F came up which is the fuel pump module, pictures attached of screen. We then were able to get the car home and it was towed to a Chevy dealership the following day. There techs were able to find a recall number of 21V739000 which was issued on 9-23-2021 showed that this happened in certain 2021 Tahoe's. While our vin number did not fit into the vin numbers on the recall number I still feel this was the issue. I feel this could be a bigger safety issue with other vehicles on the road that did not fit into that recall could still have the issue. While we were lucky and know one was injured the next people may not be so lucky. Also since our Tahoe was not in the range of VIN numbers on the recall we are being forced to pay out of pocket 521.81. Which I will be fighting Chevrolet to pay us back.

  The sunroof made a very loud popping noise and exploded while driving on the interstate on November 30th around 12:15pm in about 40-50 degree temperatures. There were no warnings or noises or any indications that something was wrong. The safety of myself and children were put at risk, as the glass came down into the car while driving on the interstate, and presumably the safety of other drivers if some of the glass flew off onto the interstate. A local body shop has taken photos, as have I, and we have filed a claim with our insurance company. Our local GM dealer did not want to cover the cost under warranty, claiming there was no way to prove exactly what happened.

  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.

  I am writing to formally document serious engine defects I have experienced with my 2021 Chevrolet Tahoe equipped with the 5.3L L84 V8 engine. 1.Crankshaft Failure: My Tahoe suffered a catastrophic crankshaft failure that required major repair/replacement. I am aware that GM has recalled certain vehicles equipped with the 6.2L L87 engine for crankshaft and rod-bearing defects. Based on my experience, the same or a very similar defect has also occurred in my 5.3L engine, which is currently not included in that recall. 2.Valve Lifter Failure: In addition, my vehicle has suffered from valve lifter collapse—a well-documented problem in 2021–2022 GM trucks and SUVs with both the 5.3L and 6.2L engines. This caused severe misfiring, drivability issues, and expensive repair needs. Why this is a concern: •Both failures occurred well before what would be expected of a modern engine. •The crankshaft failure raises a safety risk: sudden loss of propulsion while driving could lead to accidents. •The lifter issue is widely reported by other owners and has been the subject of GM service bulletins. •Taken together, these problems suggest systemic defects in the 2021 Tahoe’s 5.3L engine that have not been adequately addressed by GM. Requested Action: •I ask GM to extend recall and warranty coverage to include the 5.3L L84 engine in addition to the 6.2L L87. •I ask NHTSA to consider investigating whether the scope of the current 6.2L recall should be broadened to include 5.3L engines, given failures like mine. •At minimum, I request assistance in covering repair/replacement costs for both the crankshaft and lifter defects, which are clearly not due to normal wear and tear.

• 11/14/2025· ENGINE,FUEL/PROPULSION SYSTEM

  1. What component or system failed or malfunctioned, and is it available for inspection upon request? Answer: The vehicle’s 6.2L L87 V8 engine suffered a sudden internal mechanical failure involving the connecting rod, rod bearings, and crankshaft assembly, resulting in catastrophic engine damage. The failure mode is consistent with the defect described in GM Recall N252494001. The engine and all damaged components are fully available for inspection upon request. 2. How was your safety or the safety of others put at risk? Answer: The engine failed without warning while the vehicle was in motion, causing an immediate loss of propulsion. This created a hazardous situation where the vehicle could no longer accelerate or maintain speed in traffic, increasing the risk of a rear-end collision or loss of vehicle control. GM’s own recall documentation identifies this exact failure mode as a significant crash risk, and that same hazard occurred in my case. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Answer: Yes. A service technician confirmed catastrophic internal engine failure consistent with connecting-rod or crankshaft damage. The dealer also verified that the engine is inoperable and requires full replacement. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Answer: No, the engine failed while in motion and was taken to the closest mechanic. Inspections by an insurance representative or manufacturer representative can be arranged. The vehicle and damaged engine remain available for further examination. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Answer: No. There were no warning lamps, diagnostic messages, or drivability symptoms prior to the catastrophic engine failure. The failure occurred suddenly and without any advance indication. All service records are available

However, based on the recall description and the symptoms outlined, I believe my vehicle experienced related issues and should be considered for inclusion. While driving down the highway my vehicle experienced power failure leading to a full stop in the middle of the highway, resulting in a 9-1-1 call due to safety concerns for myself and oncoming traffic. The car was later diagnosed with the fuel pump module failure that other vehicles within the same year & model experienced, which were included in the recall.

  I am submitting this complaint to the National Highway Traffic Safety Administration (NHTSA) regarding a sudden engine failure in my 2021 Chevrolet Tahoe equipped with a 6.2L V8 engine, which posed a serious safety risk. I was driving on the highway at approximately 65 mph with cruise control engaged. Suddenly, the vehicle lost all power, disengaging the cruise control, and the check engine light began flashing rapidly. I managed to exit the highway safely. While stopped at a traffic light, preparing to turn into a nearby repair shop, the car started shaking violently from side to side, making it difficult to control. I took the vehicle to a Firestone shop and a local Chevrolet dealer, both of which diagnosed massive engine failure and indicated that the engine will most likely need to be replaced. The symptoms I experienced—sudden loss of power at highway speeds, flashing check engine light, and violent shaking—are in line with issues reported in other GM 6.2L engines that have been recalled.  For whatever reason, my 2021 Tahoe, which falls in the middle of the affected model years for these recalls (e.g., GM recall N252494001 for 2021-2024 vehicles with 6.2L V8 engines due to defects in connecting rods and crankshafts leading to engine damage and loss of propulsion), is not included under the broader GM 6.2L engine recall,  although I experienced very similar issues. The biggest safety concern was the engine essentially losing power at highway speeds, which could have led to a crash. I urge NHTSA to investigate and expand coverage if necessary to ensure public safety.

  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.
