The contact owns a 2006 Chevrolet Impala. The vehicle was taken to the dealer on several occasions for failures with the heater blowing cool air, the gear shift changing incorrectly, and the tire monitor indicator constantly illuminating. On January 30, 2008, the contact drove approximately 25 miles. She then pulled into the driveway and noticed smoke underneath the hood, followed by flames. She quickly extinguished the fire and the vehicle was towed to the dealer. It was diagnosed that the power steering hose failed and caused the fluid to leak. The vehicle will be repaired. The current and failure mileages were 51,000.
