While driving, my Chevrolet Tahoe suddenly developed a severe, rhythmic bottom-end engine knock, indicating a catastrophic internal mechanical failure. I immediately took the vehicle to an authorized Chevrolet dealership on May 29, 2026, for emergency diagnosis.The dealership technicians officially diagnosed the issue as a severe lower-end engine failure. They deemed the engine unrepairable and determined that a complete long-block engine replacement is required.As of today, July 6, 2026, the vehicle has been sitting at the dealership for over 5 weeks and has yet to be fixed. The prolonged delay and sudden mechanical failure present a severe safety hazard, leaving me without a vehicle due to known GM manufacturing defects currently under the federal safety agency investigation. This report is being filed to document the failure of the 6.2L engine lower end, the necessity of a full long-block replacement, and the ongoing repair delay.

The vehicle in question had approximately 5000 miles when low oil light came on, it was 2 quarts low. this was after the first oil change at around 3500 miles. I had the dealer do an oil consumption evaluation. They check the oil every 500 miles and confirmed it was using 2 quarts every 2500 miles. They informed me GM says this is normal. I cannot disagree more with that claim. GM knows they have a problem with the 6.2-liter engine. I have researched the issue and found they have a problem with the crankshaft machining and the oil delivery port beveling that delivers lubrication to the connecting rod bearing appears to be too large that causes the motor oil not to consistently keep the bearing lubricated. This causes the engine to be an "oil burner" and premature failure of the bearing. They think putting a heavier viscosity of oil in will delay the inevitable engine failure, which makes me believe they are aware of the faulty manufacturing and want to run from their warranty responsibilities.
