NHTSA Complaint #10343551 — 2005 MAZDA MAZDA6

WE WERE DRIVING FROM LOS ANGELES, CA TO FREMONT, CA ON THE I-5 HIGHWAY. WEATHER WAS HOT - ABOUT 95F TO 100F THAT DAY. ABOUT MID-WAY IN OUR DRIVE, THE CAR BECAME VERY JERKY WHEN I LIFT OFF, OR STEP BACK ON, THE THROTTLE. I PULLED OFF TO THE CLOSEST EXIT AND PROCEEDED TO A GAS STATION. AS WE WERE ROLLING TO THE GAS STATION, I NEEDED TO STEP EXTREMELY HARD ON THE BRAKE PEDAL, BUT WAS STILL NOT ABLE TO COMPLETELY STOP THE VEHICLE. VEHICLE KEPT ROLLING AT ~5 MPH DESPITE I STEP HARD ON THE BRAKE. I NEEDED TO PUSH THE TRANSMISSION LEVER TO NEUTRAL, AND THEN PULLED THE HAND-BRAKE TO COMPLETELY STOP THE VEHICLE. AFTER THE CAR WAS STOPPED, THE ENGINE RPM HOVERED BETWEEN 2K - 3K RPM, BUT MY FOOT WAS OFF THE GAS PEDAL ALREADY. THE CHECK-ENGINE-LIGHT WAS NOT ON, AND THE CAR WAS NOT OVERHEATING. WE OPENED THE HOOD AND CHECKED THE FLUIDS, AND EVERYTHING WAS NORMAL. WE FELT WE WERE NOT ABLE TO STOP THE CAR BECAUSE OF THE ENGINE HOVERED AT 2-3K RPM DESPITE MY FOOT BEING COMPLETELY OFF THE GAS PEDAL. WE THEN SHUT DOWN THE CAR. AFTER 10 MINUTES, WE RE-STARTED THE CAR AND EVERYTHING WAS NORMAL AGAIN. IT HAS BEEN ~500 MILES SINCE THIS INCIDENT BUT THE ISSUE HAS NOT RETURNED YET. NONETHELESS, WE FEEL THAT IT IS A DANGEROUS SAFETY ISSUE BECAUSE WHEN IT HAPPENED, THE CAR CANNOT BE SAFELY STOPPED. *TR
