Typical engine symptoms owners report

  • Engine stalls or completely shuts off while decelerating, braking, or coming to a stop, sometimes repeating several times a day.
  • Engine stalling occurs more often when the engine is cold or in hot ambient air, with the clutch engaged and shifter in neutral.
  • Engine revs drop to near zero and dies when the clutch is pressed to shift, especially before the engine is fully warmed up.
  • Some owners describe sudden unintended acceleration or full-throttle surges immediately after starting, in one case leading to a crash.
  • CVT-equipped cars show a rev-pause-drop pattern when the throttle is applied, described as hesitation during passing or merging.
  • An abnormal engine noise was reported shortly after purchase, which the dealer said could not be fixed.
