What owners report

  • Vehicle unexpectedly surges or lunges forward when slowing down near a stop, sometimes even with the brake applied.
  • Sudden forward surge while turning into a parking space caused loss of control and a crash.
  • ABS reportedly failed to engage during braking at 35 mph, resulting in a rear-end collision with no airbag deployment.
  • Engine lost power with reduced steering and braking assist, tied to a throttle body trouble code that recurred repeatedly.
  • Dashboard vibrates constantly at various speeds and develops a visible crack near the passenger airbag housing.
