NHTSA Complaint #10663612 — 2009 TOYOTA COROLLA

DEALER DID SMART STOP TECHNOLOGY, UPON PICKING UP CAR NOTICED IT RUNNING ROUGH. AFTER DRIVING A FEW MILES IT SEEMED TO IMPROVE. OVER A PERIOD OF A FEW MONTHS AND APPROX 3000 MILES ENGINE PERFORMANCE AND FUEL MILEAGE HAVE GOTTEN MUCH WORSE, MILEAGE HAS DROPPED OFF ALMOST 10 MPG! TOOK THE CAR IN FOR NYSI TODAY AND ASKED DEALER ABOUT THIS. WAS TOLD BY SERVICE ADVISOR THAT THE CAR HAD TO RELEARN CERTAIN FUNCTIONS. ASKED HOW LONG THIS SHOULD TAKE AND WAS TOLD A FEW MONTHS? I SAID TO THEM THEY IT HAS ALREADY BEEN A FEW MONTHS AND ABOUT 3000 MILES. TO ME THIS IS UNACCEPTABLE. I WILL GIVE IT A COUPLE THOUSAND MORE MILES AND SEE WHAT HAPPENS. IF I SEE NO IMPROVEMENT I WILL BE BACK TO THE DEALER LOOKING FOR ANSWERS. DRIVING HABITS HAVE NOT CHANGED FROM PRE SMART STOP. THIS IS ALSO A HIGHLY MAINTAINED VEHICLE AND HAS BEEN SERVICED AT THE SAME DEALER SINCE NEW. *TR
