Potential causes and fixes

What to do
  1. Check for recalls: Verify if your vehicle is included in any recalls, such as the one for the start/stop accumulator. 
  2. Visit a dealer: Have a dealership perform a diagnostic scan to check for trouble codes, even if no check engine light is on. 
  3. Ask about software updates: Inquire if a transmission control module (TCM) software update is available, as this is a common fix for shifting problems. 
  4. Inspect transmission fluid: Have a mechanic check your transmission fluid for level and condition. 
  5. Consider warranty: If your vehicle is still under warranty, be sure to have all issues addressed by an authorized dealer, as a factory warranty should cover necessary repairs.
