What owners report

  • Vehicles lose power and illuminate multiple warning lights after a rear inverter fails, sometimes recurring after repair.
  • The 12V accessory battery reportedly stops charging from the main battery, leaving the vehicle unable to start, unlock, or charge.
  • Windshield wipers can stop moving entirely when slush or ice builds up at their base, reducing visibility while driving.
  • Adaptive cruise control has surged toward the vehicle ahead after apparently losing radar tracking on curves.
  • Highway Driving Assist has disengaged without any visual or audio alert, leaving drivers unaware the system stopped controlling the car.
  • Lane Keep Assist has failed and let the vehicle drift toward the outside of its lane without triggering a warning light.
