What owners wrote
I and my 7 year old daughter and her friend were entering my driveway on aug 14,2006, paused to open my garage door from the car and I was slowly moving in. All of a sudden car went out of my control in a flash that I did not even have time to react. It went and hit our other parked car in the garage with such a huge force that the second car literally went and tore the bedroom wall. Our second car is badly damaged on the front, back and one side (scraping a pole in garage) and wall needs fixing too.
Consumer complained about having problems with the pulleys making a hole in the oil pan. Manufacturer was not notified at the time of this call. The vehicle had an oil leak. The technician stated the leak was caused by a pulley which was hitting against the oil pan. The technician stated that if the oil pan was replaced the pulley will still hit the oil pan and cause a leak. The check engine light illuminated. The dealer replaced the mass air flow sensor. *nlm
