What owners report

  • Vehicles reportedly shift into Park while the engine is still running, then lurch forward or backward unexpectedly, sometimes causing collisions.
  • Owners describe the parking brake failing to hold the vehicle on an incline, causing it to roll despite being set.
  • The liftgate area is linked to reports of the vehicle rolling backward on its own after the driver exits.
  • Adaptive cruise control and collision avoidance systems reportedly malfunction, braking for objects that are not present or disengaging suddenly.
  • Evasive steering assist has been reported to cause a loss of steering control at low speeds, with drivers feeling disconnected from the front tires.
  • Electrical system complaints include vehicles catching fire, in one case after installation of an aftermarket brake controller and in another after the engine seized while starting.
