Car starts smoking and making noise while driving a day before scheduled appointment. Car towed to dealer 6/23/2020- rods in engine went bad, engine needs to be replaced. 360 point inspection November 2019. This car was bought used and has been serviced at the dealership since purchase. It is frustrating the dealership in may 2020 did not detect a problem and I am now at this point. The check engine light comes on continuously and we have been to the dealership at least 4 times in the past year for this check engine light issue. What's the point of using a dealership to service your car?.
I was driving down the road, no warning lights came on. Oil pressure gauge was normal and the car just stopped. Made no noises, just stopped. Technician pulled oil pan and stated that hunks of metal fell out around the bearings.
Without any warning lamps or extraneous sounds or engine noise, traveling approximately 40mph, the engine seized up and stopped. Immediately the engine, oil and battery lamps illuminated, and I was able to coast into a safe parking lot away from traffic. I attempted to restart the engine to no avail. Aaa was called and told to tow the vehicle to a local shop. Their diagnosis concurred with mine. . . The engine had seized and was not repairable except to replace the engine.
