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.
