My Toyota Corolla started making a hammering noise when pressing the accelerator I was going downhill on the expressway. I drove to the nearest town and called Toyota who informed me I had to get a tow truck and get it to the dealership for service. I did so, and the next day was informed that the car's engine needed replacement as it had been damaged due to lack of oil. I was surprised since my car's last service was at the same dealership for an oil change just a month and two weeks before. At that time they did not indicate a problem with the motor and said my car was ok. My car has 49,500 miles and I am now facing a very expensive repair (change all the internal motor parts) since my car's 5 year/60,000 warranty expired just last month.
