The ball joints cracked which caused the front left tire to become detached from the vehicle while driving approximately 70 mph on the freeway. The consumer contacted the manufacturer but they have not done anything about the issue. The vehicle's tcm/ecm software failed which caused the transmission to slip/surge while driving. The vehicle would not go into reverse due to an internal failure. The dealer replaced the a/t assembly and flushed the a/t fluid. The left sunvisor was coming apart. The visor clips broke and as a result they could not hold the visor in a stable position. Seat belt bolt cover broke. The passenger side door lock was hard for the passenger to unlock from the driver's side. The dealer replaced the door latch and actuator assembly. The vehicle's heater took about an hour to effectively warm the vehicle. The dealer determined that the blend door was loose at the actuator.
