2019 Chevrolet Tahoe: engine failure

Filed Oct 21, 2026 · Engine · TX

At approximately 80,700 miles, I started my 2019 Chevrolet Tahoe (6.2L V8) to take my family on errands. My wife heard a squeaking noise from the engine as she walked to the vehicle, and I got out and heard the same noise. No warning lights or messages appeared on the dashboard, before or after. I took the vehicle to an independent repair shop, expecting a belt problem. After inspection, the shop told me the valve lifters had failed and needed replacement, and that the camshaft would likely need replacement as well. I declined the repair and took the vehicle to a GM dealership for inspection and documentation. The GM dealer confirmed the lifters need replacement. They could not confirm whether the camshaft is also damaged without an engine tear down, which I have not authorized. The dealer estimated $13,200 to replace the lifters and camshaft. The independent shop estimated $8,200. The vehicle has not been repaired, and the failed components are still in the engine and available for inspection. I am concerned for my family’s safety. Lifter failure on this engine can cause misfires, loss of power or engine failure while driving. We use this vehicle to transport our family, and a sudden loss of power on the road could cause a crash.

6.2l Engine Failure: Vehicle was purchased last November at 113000 miles and at approximately 127000 miles we heard a noise coming from our engine one morning. Took it to the dealer we purchased the truck from because we bought an extended warranty and they got back to us and said there were metal flakes in our oil. They dove deeper and said it was connected to internal engine failure. They told us we could keep driving it but we said no that’s too dangerous and current it’s sat 3 weeks on their lot while we figure out what the warranty company is going to do and if we’re going to be able to get a new motor from GM. I owe $40,000 on a car that is basically junk and idk what to do. When my dealer told me GM only put 21-24 in their recall I started digging and found out the entire L87 6.2 gas platform is plagued. Please be informed that my maintenance records are also intact with regular scheduled oil changes performed by professionals. Please help!

While driving, the engine started to shutter and run rough. Pulled over to check and see if everything was ok. When restarting engine it developed a ticking noise which got worse and worse. We then made an appointment at a transmission specialist to get it serviced. While driving there the engine started experiencing engine failure with loss of power and loud ticking noise.

Had to pull over and have towed. Independent service center has confirmed issues. Report in attachments. No warning lamps or messages appeared prior to failure issues. The issues first started on March 18th 2026. SUV has been un drivable since. We have been unable to find a repair shop who is willing to do the repairs needed. The vehicle really needs a whole new engine.

My 2019 Chevrolet Tahoe Premier equipped with the 6.2L V8 engine has experienced a major internal engine failure. The dealership diagnosed camshaft bearing failure with a recorded misfire on cylinder #5. The engine oil was drained and inspected and no significant metallic debris was found, and the dealership noted no evidence of abuse or neglect. Intermittent drivability concerns were present over the life of the vehicle and were addressed through professional diagnosis and repair each time. The vehicle has been properly maintained since new. Just months prior to this failure, the vehicle underwent full diagnostics and significant repairs, and no internal engine failure was identified. This failure appears consistent with a known defect pattern affecting GM 6.2L engines involving internal valvetrain or camshaft-related failures. The failure resulted in abnormal engine noise, misfire, loss of power, and the vehicle becoming unreliable for safe operation. General Motors has declined goodwill assistance citing warranty expiration, despite the nature of the failure being a non-wear internal engine defect. I am submitting this complaint so this VIN and failure can be reviewed as part of any ongoing investigation into 6.2L engine failures.

On 10/23/24 the vehicle's 6.2 L L87 engine seized while driving on a state highway (similar to the later models already under recall) putting myself and other drivers at risk through a sudden loss of power and speed. The component was inspected at a GM dealership and then replaced AT MY COST. The replacing mechanic said the failure was in the rod bearings (the same as in the recalled engines). There were no warnings or related problems prior to the sudden failure. The existing recall ( Investigation:PE25001) needs to be expanded to these earlier model (2019 and 2020) engines that have the exact same issue.
