Engine failed at 137,000 miles. The vehicle is available for inspection. The engine failed while driving with no warning lights, or indications that anything was wrong. It started with a knock that gradually got worse and worse over the course of 5 miles. Once it shut down it failed to ever restart again. Te vehicle was inspected by a Manufacturer Dealership, they did not give me specific insights as to what caused the engine to fail other than that there was no oil present in the engine at the time of inspection. However I have every oil change receipt, documenting regular, on time oil changes.
