What owners report

  • Electric power steering can fail suddenly while driving, sometimes producing a fault code for a shorted steering rack and leading to a loss of control.
  • Owners describe the vehicle lunging or lurching forward unexpectedly at a stop while the brake pedal is still depressed.
  • Some report the vehicle creeping or accelerating forward on its own when the brake-hold feature is released, with the brakes failing to stop it.
  • Headlights are described as too dim for nighttime driving, with dealers unable to resolve the issue after bulb adjustments.
