LOVED THE CAR. GOT 23--30 MPG. TOOK IT FOR 10K FREE CHECK-UP. THEY INSTALLED SOFTWARE FOR FACTORY RECALL.

AFTER INSTALLATION MILEAGE DOWN TO 19-27MPG. CHECKED AFTER 2500 MILES TO GIVE IT TIME TO RESET. CAR ALWAYS RAN WELL AND STILL DOES. ASKED TO GET SOFTWARE RESET OR A CHECK THAT THEY INSTALLED THE CORRECT SOFTWARE AND GOT POLITELY IGNORED. WENT FROM LOVING THE CAR TO NOT HAPPY BECAUSE OF THE "POOR" MILEAGE COMPARED TO WHEN I RECEIVED IT FROM THE FACTORY. LOSING 3 TO 4 MPG IS CRAZY!!! I WANT THE CAR I BOUGHT BACK. HESITANT TO EVER TAKE IT BACK TO THE DEALER.
