NHTSA Complaint #10965991 — 2003 BUICK CENTURY

WAS DRIVING UP A GRADE AND THE VEHICLE FAILED TO DOWNSHIFT TO CLIMB THE GRADE PROPERLY ON THE FREEWAY SO REMAINED AT 60 MPH WHILE IN DRIVE. VEHICLE ALSO SEEMED TO ACCELERATE UNDER ITS OWN POWER WHERE I HAD TO STOP THE VEHICLE BY PUTTING IT INTO NEUTRAL IN ORDER TO BRAKE SAFELY ALMOST AS IF I WAS BRAKING AS THE VEHICLE WAS ACCELERATING. I WAS AT 55 MPH ON A FLAT SERVICE WITHOUT EVEN TOUCHING THE ACCELERATOR. I DID NOTICE HIGHER RPMS WHILE IN NEUTRAL. I DID TAKE IT TO A GARAGE AND THEY COULD NOT DUPLICATE THE PROBLEM AND MY FRONT BRAKES NEEDED TO BE REPLACED UNDER THE CIRCUMSTANCES. THE VEHICLE WASN'T THROWING ANY CODES EITHER. I KNOW I'M NOT THE ONLY ONE THAT HAS WITNESSED THIS ISSUE AND I'M SURE THE MECHANIC I TOOK IT TO DID HIS JOB PROPERLY IN ATTEMPTING TO DIAGNOSE THE ISSUE HOWEVER IT JUST COULDN'T BE DUPLICATED. NOT ABOUT TO PAY DIAGNOSTIC FEES AT DIFFERENT PLACES IF I'M CHASING AFTER A GHOST. ANY FEEDBACK IS TRULY HELPFUL BUT NOW MY WIFE IS LEFT DRIVING A CAR SUBJECTED TO HAVING THAT SAME ISSUE IN THE NEAR FUTURE QUITE POSSIBLY AND WE JUST HAD A GARAGE SIGN OFF ON NOT BEING ABLE TO DUPLICATE THE PROBLEM. HOPE THIS INFORMATION HELPS.
