2022 Chevrolet Tahoe engine problems

ENGINE

2022 Chevy Tahoe went into limp mode at 62,500 miles out of the blue and check engine light came on. At the certified Chevy dealership I was told it was the transmission control valve, Code P2732, which is a known widespread factory issue in these models. Upon further inspection, was told my transmission fluid was completely black and burned and it ruined the transmission and therefore it needs to be replaced. "Consequential Damage Policy: When a control valve body fails and stays "stuck on," it forces maximum line pressure through the system. Continuing to drive under these conditions quickly destroys the internal clutch packs, burns the fluid, and melts down the transmission." This is exactly what happened and my vehicle was never put on a recall list but clearly was a ticking time bomb.

ENGINE

Driving the vehicle down the highway at approximately 65 miles per hour, the check engine light came on and the engine went into limp mode, slowing immediately. Upon getting the vehicle to the left shoulder on a busy highway, the vehicle displayed "engine overheating", "battery low", and 0% oil life. A full oil and filter change had been done less than 1000 miles ago and upon checking the oil, it was at the correct level. The engine completely failed and is not being replaced at a Chevrolet dealership. I completed the recall N252494003 on March 5th, 2026 which comprised of an engine inspection, higher viscosity oil, a new oil cap, filter replacement, and owner's manual insert. The engine still failed and required replacement despite having this done.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at various speeds, the check engine warning light was flashing, and the vehicle was shuddering. The vehicle was taken to the dealer several times, and it was diagnosed with a misfire in cylinder #5. The dealer informed the contact that the engine was taken apart during the diagnostic process, and the vehicle was repaired; however, the contact expressed doubts that the engine was taken apart or repaired because the dealer had only sent pictures of the exterior of the vehicle to the warranty company. Additionally, the failure recurred while driving. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 85,000.

ENGINE

The contact owns a 2022 Chevrolet Tahoe. The contact stated that at approximately 55,000 miles, the vehicle experienced a torque converter failure, and the torque converter was replaced under the factory warranty. The contact stated that four months later, the failure reoccurred, and the dealer declined to cover the repair. Subsequently, the camshaft failed, leading to a recommendation for a complete engine replacement. The contact stated that old parts from the original engine were installed on the new engine without authorization. Two months after the engine replacement, the transmission valve body failed while the vehicle was 237th on a back-order list. Three months after a second transmission repair, the vehicle suffered another transmission failure. The contact was informed that the transmission was new but discovered but was being charged for the installation of old, faulty parts from the original engine onto the new powertrain. The vehicle was currently at the dealer, and the contact was without transportation. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 130,000.

I had the recall for the Momentary Rear Wheel Lock-up completed on 2025-05-04. While I was driving March 2026 my Tahoe went into limp mode and I had to have it towed because it wouldn’t reverse it was towed a day after this happened to Lynch Chevrolet. It has sat there ever since with no fix in site. I had to get a rental vehicle that GM is paying for but they have stipulations to what they pay for and the vehicle they gave is not comparable or better than MY car. Not only is this an inconvenience but they are doing the bare minimum to help with their mistakes.

ENGINE

My 2022 Chevrolet Tahoe has a recurring pattern of excessive oil consumption, smoke from the exhaust, repeated check engine light events, P0420 catalyst-efficiency faults, and repeated catalytic-converter-related repairs. At approximately 75,000 miles, the vehicle shut down on the freeway. At approximately 121,000 miles, the first catalytic converter failed. Chevrolet of Wesley Chapel documented P0420 and catalyst failure in November 2025, and GM service history reflects catalytic-converter replacements at 131,468 miles and approximately 141,082 miles. The vehicle also underwent major injector-related repair in early 2026. At 141,620 miles, Chevrolet of Wesley Chapel started an oil consumption test and stated in writing that oil consumption can lead to repeat failed converters and false oxygen sensor readings. Despite substantial repairs, the problem pattern continued. I am reporting this as a possible safety-related defect affecting engine operation, emissions-system failure, and drivability, and I am asking NHTSA to review whether this indicates a broader safety-related defect.

ENGINE

Driving down I495 in Mass when engine stopped with no warning or prior symptoms. My wife and 4 children (including 2 friends of our kids) were in the car. Luckily we were able to safely pull to the shoulder after coasting through a construction zone. If we hadn’t made it to a safe piece of shoulder chances are high that another vehicle would have hit our vehicle and hurt and killed us. These 6.2 engines are a serious safety hazard and I only hope my new engine proves to be reliable. Car was towed to dealer who diagnosed it as a seized motor. Car is a 2022 Chevy Tahoe with the problematic 6.2 engine. Engine had passed Chevrolet’s Pico test as per the 6.2 recall about 7,000 miles before it seized. Vehicle and engine dealer maintained with all required changes/maintenance. Engine seized/failed with no warning.

ENGINE

The vehicle shifted itself into neutral and shut off while driving. It happened twice in three days. The first time I was pulling into the driveway so I was able to put it in park and restart the car safely. The second time I was in the middle of traffic in Tampa and it shifted into neutral and shut off in the middle of the road. Luckily no cars hit me but again I had to apply the break , restart the car and put it back in drive. This was very scary and I had my kids with me. Earlier in the day I had been driving on 75 and if it had happened then it could have been a bad wreck. It shows there are no current recalls on my vehicle. No warning lights or messages appeared. Vehicle was purchased less than 30 days ago. I will contact the dealership to verify there are no open recalls just in case but again when I checked I found none.

On May 9th, 2025 we had to have our 2022 Tahoe towed to the local dealership. There was a transmission error message and the battery was completely drained. The dealer put a new battery in it for $485 and we were told it was good to go. The next day, the car would not go into Reverse. Had to have it towed back to the dealership and was told that the Transmission failure was a recalled part and would be covered. Later we were called and told even though the part that had failed is in fact the same part in the open recall, that our VIN was not on the recall list and the cost to fix the vehicle would not be covered. In addition to all the headaches and money out of pocket (rental cars, tows, new battery) we now have to wait at least 4 - 6 weeks to receive the recalled part but since our VIN is not on the 2022 Tahoe recall list (even though it is the same part as the recall that failed), we are having to pay out of pocket for the repairs. Chevy needs to stand behind this recall and cover the cost.

Dear. My name is [XXX] . Phone # [XXX] . My email: [XXX] On [XXX] my Tahoe suddenly shut off while I was driving over 70 mph on the highway. It was towed to the South pointe chevrolet dealership in tulsa. I was told a fuse had failed and paid nearly $400. On April 17, 2025 they returned my Tahoe and said it fixed. [XXX] When i tried to start engine, then it acted like something almost can't start, then i text dealership and told them situation. On [XXX], the same failure occurred again — again at highway speed — nearly causing an accident with an 18-wheeler. The Tahoe was towed a second time. 2 times i was able to re-start engine drive until i stop then can't start it agian. Both time i smell something burned when i tried to re-start it. On April 21, I texted the service manager about GM TSB N252494000, which describes propulsion loss involving the L87 engine — the same engine in my Tahoe. Two days later, I was sent an invoice for $865.30 for a starter replacement. I was told the repair would not be covered under warranty — despite the vehicle still being under 60,000 miles at the time and the defect appearing to fall under a known GM issue. This is a recurring, life-threatening failure that GM and its dealer have not fixed. The vehicle is still under warranty, yet GM is refusing to cover the repairs.
