NHTSA Complaint #10871126 — 2010 TOYOTA 4RUNNER

VEHICLE RANDOMLY AND SUDDENLY REVS ITSELF BOTH FROM A STOPPED POSITION AND WHILE DRIVING. WHEN DRIVING DOWNHILL AND I TAKE MY FOOT OFF THE GAS THE VEHICLE WILL CONTINUE TO REV ITSELF AROUND 3000 RPM THEN WHEN I START TO TRAVEL UPHILL IT WILL DOWN SHIFT TO ABOUT 1500 RPM. THIS SEEMS BACKWARDS. TAPPING BRAKES DOES NOT CAUSE IT TO DOWNSHIFT AS NEEDED, DOES NOT SEEM RIGHT TO APPLY BRAKES AND VEHICLE CONTINUES TO REV ITSELF HIGHER NOR DOES IT SEEM RIGHT TO TAKE FOOT COMPLETELY OFF THE GAS PEDAL AND THE VEHICLE CONTINUES TO REV UP. THE ONLY WAY TO GET IT TO IDLE IS TO APPLY PRESSURE TO THE GAS PEDAL AND SPEED UP WHICH IS DANGEROUS WHEN ALREADY GOING DOWNHILL. WHEN TRAVELLING IN A PARKING LOT IT REV ITSELF UP AND WILL JUMP FORWARD. FROM A STOPPED POSITION SUCH AS IN MY DRIVEWAY OR AT A STOPLIGHT I WILL PRESS THE GAS AND IT WILL NOT GO INTO DRIVE BUT IT WILL REV UP TO ABOUT 3500. NONE OF THESE ISSUES CAN BE DUPLICATED BY THE DEALERSHIP OF COURSE. AT ONE POINT THEY FINALLY CHANGED OUT SOME TYPE OF COMPONENT IN SHIFT MECHANISM AND THAT WORKED FOR ABOUT A WEEK THEN THE PROBLEM STARTED AGAIN. THERE IS NEVER A CODE INDICATING THERE IS ANYTHING WRONG ALTHOUGH THE TRAC LIGHT WILL RANDOMLY COME ON AND NOT TURN OFF. I HAVE BEEN DRIVING FOR 30 YEARS AND KNOW WHEN A CAR IS NOT DRIVING PROPERLY. THIS IS MY 2D 4 RUNNER. FIRST WAS AN '03 AND HAD SIMILAR ISSUES BUT SINCE WAS LESS THAN A YEAR OLD I FINALLY CONVINCED THE DEALERSHIP TO REPLACE THE TRANSMISSION AT TOYOTAS COST. THIS ONE WAS PURCHASED USED AND HAS MORE MILES ON IT BUT IT SEEMS TO BE THE SAME PROBLEMS AS MY ORIGINAL. THE ONLY WAY I HAVE BEEN ABLE TO GET DEALERSHIP TO BELIEVE ME IS TO ASK THE SERVICE MANAGER TO DRIVE MY VEHICLE FOR SEVERAL DAYS THEN THEY ARE LIKE OH I SEE WHAT YOU MEAN. ANOTHER INCIDENT WAS ON A SNOW PACKED ROAD. TRAVELLING 10MPH WHEN THE VEHICLE DOWNSHIFTED I LOST CONTROL.
