Typical transmission symptoms owners report

  • Owners report sudden, unintended engine revving to high RPM while stopped at a light or in a parking spot, causing the car to lurch forward.
  • Some describe a valve board failure inside the transmission that caused unexpected deceleration and left a lingering delay when accelerating after repair.
  • Several owners say the engine will not shut off after pressing the start/stop button, requiring repeated presses or jiggling the shifter while auxiliary power stays on.
  • A cluster of complaints describes the shift lever or park switch acting loose or unreliable, preventing the ignition from fully powering down even when the lever shows park.
  • One owner reported the car crashed into a tree when the engine continued to rev as if trying to accelerate after braking to park.
