The dealer produced a failure code detected for the torque converter clutch lock up and recommended that the transmission assembly be replaced. On February 24, 2012, an ecm recall repair was performed. Also in 2012, the contact noticed rust on the hood of the vehicle and small white circles (the size of basketballs) on the rear bumper and trunk. Two years later, leopard like spots were present on the roof of the vehicle. The manufacturer and dealer were notified of the defects. The manufacturer scheduled an appointment with the dealer in December of 2016 for diagnostic testing. The dealer determined that there were only paint chips on the vehicle and failed to include the extensive amount of rust on the roof. The service manager informed the contact that they would use oxidation on the vehicle regarding the rust. The manufacturer stated that the paint used on the vehicle was environmentally safe. In addition, the contact received a recall notice for the air bags. It was unknown if the notice pertained to the passenger or driver side air bag. The NHTSA campaign numbers and failure mileage were not provided. The VIN was invalid.
