Typical transmission symptoms owners report

  • Owners report the CVT hesitates or delays acceleration from a stop or when turning, sometimes lurching forward suddenly once power engages.
  • Some describe the vehicle rolling backward briefly after shifting from reverse into drive before the transmission engages.
  • Several owners report transmission oil leaking near the seal cap area, tied to the recall for the deformed seal cap.
  • Cold-start behavior includes the transmission staying in a lower gear than normal for several miles, causing higher than expected engine RPM.
  • A few owners report wheel bearing (hub unit) failures on both sides of the vehicle, replaced under warranty.
