ENGINE AND ENGINE COOLING
Owner Narrative
The contact owns a 2021 Chevrolet Tahoe. The contact stated that the engine was consuming an excessive amount of oil, and there was an abnormal knocking sound coming from the engine. Additionally, the vehicle hesitated and failed to accelerate as needed, with blue smoke coming from the exhaust pipes. The check engine warning light was intermittently illuminated. The vehicle was taken to the dealer, who determined that there were metal shavings in the engine oil and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 51,000.
