NHTSA Complaint #10614566 — 2013 LINCOLN MKZ

WHEN DRIVING THE CAR IT WILL SHIFT FROM DRIVE TO S1, S2, S3, S4, IT WILL DECREASE IN SPEED, LIKE A HESITATION AND SLOWING DOWN. I AM AFRAID IF THIS CONSTANTLY HAPPENS SOME ONE WILL HIT ME IN THE REAR., CAUSING A SERIOUS ACCIDENT. WE HAVE TAKEN THIS CAR IN TWICE FOR REPAIRS, STILL ISN'T FIXED. FIRST, OH ITS NEED TO BE PUT ON THE COMPUTER AND RECALIBRATED. SECOND, AFTER TEST DRIVING THE DEALERSHIP SERVICE DEPARTMENT COULDN'T ASSESS THE CAUSE AND IT DIDN'T OCCUR WHILE THEY DID A TEST DRIVE. THIS IS A SERIOUS DEFECT AND DANGER TO ME, MY FAMILY AND OTHERS ON THE HIGHWAY. IT NEEDS TO BE INVESTIGATED AND REPAIRED.THIS IS STILL OCCURRING WHILE DRIVING DAILY. SERIOUSLY THINKING ABOUT RETURNING THIS VEHICLE. *TR
