2022 Chevrolet Tahoe: excessive oil consumption

Filed Mar 19, 2026 · Engine, Fuel system · FL

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.

Purchased brand new. Had for awhile and the veh shook. Took it in and the replaced with all brand new lifters. Still not correct than replaced with all new fuel injectors. Now when I take it in for the last several months it’s 1.5 to 2 quarts low on oil. Told that GM standard says 1.5 quarts low between oil changes is normal!!! I’m currently on an oil consumption test at each 1,000 miles snd I’m at 2 qrts with 1,500 til my next oil change. The volume on the radio goes up and the computer is stuck and you cannot turn the radio off or use the computer screen at all. You have to turn off the vehicle and start it again in order for the buttons to work.

On June 1st, I was put in a very dangerous situation while driving on the highway. Out of nowhere, my vehicle’s engine started clicking and immediately converted to a rough in the middle of highway traffic. I was terribly afraid from my life. I was headed to Duluth, GA for a meeting but had turn around and drive 31 miles back in rush hour traffic to Steve Reyman Chevrolet Dealership, in cobb county in this condition. I was extremely stressed; afraid that i could potentially be injured in an accident or fire, because of the engine. Several never before seen warning signals appeared. These signals included Service ESC, Service Traction Control, Forward Collision System Unavailable and the check engine light. I had just had my truck serviced on 5/26, as the dealership had been monitoring the oil consumption of my 2022 Tahoe. By the time, I arrived to the dealership, the service department was closed, so the vehicle was left overnight. I met with the service advisor in the morning and was told there was a cylinder 4 misfire and that a fuel injector and spark plugs was needed. After picking up, my vehicle on June 12th, the issued was not resolved and my vehicle was inoperable. I regularly service my vehicle including recommended service, so I’m not sure how something this extreme could happen. Looking back at my service records, there have been several occurrences where the vehicle stalled out and the dealer blamed the auto/start stop feature or a failed battery. All pretty ridiculous claims for a brand new truck. I’m convinced this vehicle was produced poorly. My truck has 72,325 miles on it, however I came across several forums with new body Tahoes & Suburbans with way less mileage (i.e. 4300 miles) that experienced the exact same issue. Attached, you will find all the times, I brought my vehicle in for service for a major concerning issue.
