What owners report

  • Adaptive cruise control or automatic braking activates suddenly for no reason, sometimes causing an abrupt stop while accelerating from a stop or entering a parking space.
  • Automatic braking triggers unexpectedly while cornering on the highway with no traffic nearby, decelerating the car sharply.
  • Airbag system displays a warning that passenger airbags are not engaged, and the issue reportedly persisted after a dealer recalibration.
  • Multiple electrical systems fail together, including instrument panel warning lights, rearview camera, and cruise control, without a diagnosed fix.
  • Door locks disengage on their own while driving or overnight despite being set to auto-lock, alongside lane departure and blind spot monitoring dropouts.
  • Brakes reportedly failed to slow the vehicle at highway speed in at least one case, leading to a collision, with a front radar malfunction warning appearing beforehand.
