Typical engine symptoms owners report

  • Owners describe the car lurching or accelerating on its own while the foot is on the brake at a complete stop.
  • Several report a delay of a couple of seconds when moving from a stop, followed by a hard, jerky engagement into gear.
  • Drivers describe hesitation when accelerating from low speeds (3-5 mph) or when transitioning from reverse to drive, with a lag followed by a sudden forward surge.
  • Multiple complaints describe hard or jumpy shifts between 1st-2nd and 2nd-3rd gears, sometimes worse when the engine is cold.
  • Some owners report the vehicle unexpectedly drops into what feels like neutral while decelerating, causing the engine to rev without power reaching the wheels.
  • One complaint describes independent acceleration, deceleration, jerking, and abnormal noises along with intermittent failure to start, which the dealer attributed to a software update and torque converter issue.
