2022 Chevrolet Tahoe: misfire or rough idle

Filed Oct 21, 2026 · Engine · TX

The dealership diagnosed the truck after investigating a ticking noise and engine misfire. During the inspection, they removed the valve cover and found that one of the pushrods on cylinder #5 was bent. Further disassembly revealed that both lifters on cylinder #5 had failed, causing excessive wear on the camshaft lobe. As a result, the dealership determined that the necessary repair was to replace the camshaft and all 16 lifters. The engine was then cleaned, reassembled, and tested to ensure proper operation. The root cause of the issue appears to have been a failing lifter, which led to damage of the associated valvetrain components.

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.

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.

During a normal acceleration from an on-Ramp onto a major interstate a Check Engine Light (CEL) came on with warnings of safety features no longer being active. The vehicle begin vibrating abnormally and the pedal was not very responsive. I took the next exit and stopped at an auto parts store to have the engine code checked. Cylinder #2 misfired due to an injector issue. The vehicle was confirmed to have this issue at a Chevrolet dealership. The car was a CPO through FORD and was covered. I owned the vehicle for 14 days. This unit has the L87 Motor, and had already undergone a motor replacement under the recall warranty. The injectors apparently were not replaced, only the O-Ring. Unlike many manufacturers GM has removed Fuel Injectors from their PowerTrain warranty. A motor with under 5,000 miles was not covered since the body and bolt-ons were original with 45,000 miles. GM has a very recent history of injector recalls and issues. These injectors should undergo the same scrutiny as previous GM injectors.

I’ve done some research on the Chevy Tahoe 6.2L engine failures my Tahoe experienced the same thing our Tahoe just shut off in the middle of rush hour. 2 days ago we’ve started hearing slight knocking on higher RPMs and sometimes just idling and also would have a rough idle but it would go away with no check engine lights or warnings on the dash till today we haven’t taken it to the dealership to look at do to it having 61k miles just past its warranty and us not having the finances to get the truck fixed.

Vehicle was driven into parking lot and was idling. Without warning, it began misfiring and stalled. Vehicle would not restart and was towed to the nearest dealer. The diagnosis was a fuel pump driver module that had internally shorted. Thankfully, it failed in the parking lot. We had recently arrived at this location for the winter having driven the vehicle approximately 1500 miles over 4 days. We were lucky the failure did not occur on the highway as the unexpected stalling would potentially be a significant safety concern. Please note that this vehicle is a 2022 Chevrolet Tahoe. The 2021 Tahoe was under a recall for this same issue (see recall N212332040). The dealer said that this is a common problem with these vehicles. Perhaps the recall needs to be expanded.

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.
