Typical engine symptoms owners report

  • Owners describe sudden unintended acceleration or stalling that led to loss of control and crashes while parking or at low speed.
  • Several report a shuddering, grinding, or judder sensation from the transmission/torque converter area that owners link to engine vibration, sometimes fixed temporarily with a software update or fluid change.
  • Some describe loud popping or banging noises from the engine, in one case tied to a spark plug failure that damaged the ignition coil.
  • Multiple owners report the check engine light coming on along with stalling, misfire codes, or the vehicle losing power unexpectedly.
  • A few describe vibration from failed motor mounts that they believe was caused by the same torque converter judder, in one case damaging a front axle shaft.
  • One owner reported the vehicle stalling along with dashboard warning lights, a stiff brake pedal, and gear shift problems at the same time.
