2022 Chevrolet Tahoe fuel system problems

Filed Sep 25, 2026 · Engine, Fuel system · FL

My 2022 Chevrolet Tahoe equipped with the 5.3L V8 experienced a severe engine failure at approximately 92,144 miles. The vehicle developed multiple misfires and was towed to the Chevrolet dealership for diagnosis. The dealership documented a failed lifter, significant camshaft damage, metal in the engine oil, and metal contamination throughout the engine. The engine had to be replaced with a complete long block at a total cost of approximately $14,395. I am concerned because this was a major internal engine failure at relatively low mileage, involving a lifter and resulting in extensive engine damage. GM has issued technical service information regarding lifter-related conditions and misfires affecting the 5.3L L84 engine family, which is the engine in my vehicle. GM provided $1,859.29 in partial repair assistance but has declined any additional assistance. I am reporting this failure because I believe the nature and severity of the engine failure warrant investigation for a potential recurring safety or reliability issue involving the 5.3L L84 engine.

Vehicle began making loud knocking sound XXX Towed to dealer 9/8 after holiday. They found metal in the oil and believe it needs an engine replacement. A week later I have no answers, there's no loaners available, so I am just without a car. We bought car from Zimbrick Chevy in [XXX]. It was never disclosed to us that the vehicle had an engine replacement right before we purchased. New engine lasted about 16,000 miles. Only once we saw the history of the car in the current dealership's service app did we learn about the engine replacement. This is beyond unacceptable!

My 2022 Chevrolet Tahoe diesel unexpectedly lost power while driving. I was stopped, made a right turn, and accelerated to approximately 34–40 mph on a two-way street when the vehicle suddenly shook, shifted into neutral, and the engine shut off without warning. There were no warning lights, dashboard messages, or prior symptoms before the failure. I was driving with two young children secured in car seats at the time. This created a serious safety risk because the vehicle became disabled in the roadway, and I had limited control while traffic was present. The vehicle has not yet been diagnosed, and the exact failed component/system is unknown. The vehicle is available for inspection upon request. The incident has been reported to a dealer or service center, but the problem has not yet been confirmed or reproduced at this time.

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 the federal safety agency to review whether this indicates a broader safety-related defect.

The check engine light came on on my Chevy Tahoe, November 2023. The system started to fail it would say for collision not able service ESC system. I would bring it into the shop. They would hook it up to the computer and they would say oh nothing wrong we just reset it. Then it started to shut down and it would say proceed with caution, low acceleration, no front and collision service ESC and I would have. Luckily I was in a city so I took it to the shop. They gave me a print off. Said there was no technician cleared it. I was able to make it home and I made an appointment. They put it on the computer. they said oh nothing‘s wrong. Everything‘s fine then it did it again and I was going through the mountains. I noticed that my car smelled of gas and that the gas gauge was just sucking fuel and I knew this was a problem.. they finally found out what was going on, but I feel the damage had already been done. The part that got replaced was over $1000. I had to pay out-of-pocket for it. Now my vehicle’s engine is shot.

The vehicles ability to accelerate was limited. Several system service warnings came on along with the check engine light.
