2022 Chevrolet Tahoe engine problems

“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.”

“The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the forward collision, check engine, and traction control warning lights illuminated, and the messages "Forward Collision Unavailable," "Service Traction Control," and "Service ESC" displayed on the instrument panel. An abnormal muffler sound was heard, the engine compartment vibrated, and the vehicle failed to accelerate above 35 MPH. The vehicle was taken to the dealer, where the engine was disassembled and it was determined that the lifters failed and the engine required replacement. Prior to the failure, the vehicle was taken to the dealer for an illuminated check engine warning light and an engine knocking sound; however, the dealer only cleared the diagnostic trouble codes while the vehicle was under warranty. The manufacturer was notified of the failure by phone. The failure mileage was unknown.”

“Thursday XXX - Left [XXX] on our way to [XXX] for a beach vacation on our 2022 Chevy Tahoe z71. Made it to [XXX] and spent the night there Friday XXX - Left our hotel in [XXX] and headed to [XXX]. Expected arrival time 8 pm About 40 miles east of [XXX] our Tahoe shuts down and I pull to the side of the road in the middle of nowhere. It’s 99 degrees. I called several dealerships around and decided on Ryan Chevrolet in [XXX]. I called a tow truck and wait for 3 hours. My wife and two kids walk 1 mile to a gas station. I call the XXXstate patrol to get them to park behind me as semis at 80 miles per hour are flying by me. Having semis pass by at 80 miles per hour is obviously very scary and extremely dangerous. Tow truck takes me and the Tahoe to Ryan Chevrolet and am able to drop the car there 30 minutes before they close for the weekend. Tow truck driver takes me to the XXX airport where I have managed to rent an SUV that will allow me to complete my vacation. Drive through the night and make it to my hotel in [XXX] at 2:30 am. Thursday XXX - Drive back to [XXX] Friday XXX Go to Enterprise Rental cars in [XXX], explain that I will need a car till my Tahoe gets…”

“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!”

“Had a engine failure at 93,000 miles and upon doing a vin report found out it also had a engine put it at 7,800 miles so it now has its third engine in it and also had the high pressure pump fail and the gauge cluster fail and had to be replaced”
