NHTSA Complaint #10415600 — 2004 MAZDA MAZDA6

MY 2004 MAZDA 6 WAS DEMONSTRATING A RACING ENGINE/PROBLEMATIC AUTOMATIC TRANSMISSION AND SHIFTING ISSUES (THE TACHOMETER WAS FLUTTERING AND RACING) AS I WAS BRAKING ON A MAJOR ROAD FROM 40 MPH TO A STOP AT A RED LIGHT. THE CAR WOULD NOT SLOW. I MANUALLY SHIFTED DOWN FROM 4TH TO 3RD, AND IT STILL EXHIBITED THE SAME 'BOUNCING' REVS ON ABOVE 2000 RPM. AS I APPLIED MY BRAKES THE CAR WAS DEFINITELY HESITATING TO DOWNSHIFT AND WASN'T SLOWING WELL; I PUT IT BACK INTO AUTOMATIC "D" SHIFTING AND PRESSED FIRMLY ON THE BRAKES TO TRY TO SLOW THE VEHICLE. I HALTED VERY CLOSE TO THE NEXT CAR IN THE LINE DESPITE HAVING STARTED BRAKING WELL BEFORE I NEEDED TO SAFELY COME TO A STOP IN THE VEHICLE. IN FIRST GEAR AT A STOP, THE TACH WAS FLUTTERING FROM 1000 TO 1800 (WELL OUTSIDE THE NORMAL IDLE RANGE OF 900-1100) UNTIL I PUT THE CAR IN PARK, ENGAGED THE PARKING BRAKE, AND SHUT THE VEHICLE OFF. WHEN I RESTARTED IT SEEMED TO BE OKAY BUT IT HAS DONE THIS ON SEVERAL OCCASIONS. *TR
