2011 Toyota Tacoma Speed Control & Cruise Problems

I STARTED MY TACOMA IN PARK, WITH MY FOOT ON THE BRAKE I PUT IT INTO REVERSE, THE ENGINE AND THEN STARTED TO ACCELERATE VERY FAST, SPINNING THE TIRES, IT WAS ON ASPHALT WITH SOME SAND. I PRESSED DOWN HARDER ON THE BRAKE TO KEEP IT IN PLACE AND SHIFTED BACK TO PARK, AT WHICH POINT THE ENGINE RPMS WENT BACK TO IDLE. WHEN I RETURNED TO REVERSE EVERYTHING WAS BEHAVING NORMALLY. THE TRUCK HAD BEEN IN MY HEATED GARAGE FOR A WEEK, I DROVE IT 3-4 MILES IN DRY SUNNY COLD WEATHER(32), SHUT IF OFF FOR A FEW MINUTES BEFORE THIS HAPPENED. IN THE FIVE YEARS I HAVE OWNED THE TRUCK THIS IS THE SECOND TIME SOMETHING LIKE THIS HAPPENED. THE LAST TIME WAS A COUPLE OF YEARS AGO WHILE IN DIVE IT SUDDENLY ACCELERATED. BOTH CASES WERE QUITE ALARMING BUT FORTUNATELY DID NOT RESULT IN AN ACCIDENT. THE PRIOR INCIDENT WAS REPORTED TO TOYOTA AND NHTSA.

I AM WRITING ABOUT A SUDDEN ACCELERATION PROBLEM I HAD WITH MY 2011 4X4 TACOMA. ON JANUARY 6TH, I WAS RETURNING FROM AN APPOINTMENT. I LEFT THE PARKING LOT GOING ABOUT 10-20MPH, I DROVE 1/10TH OF A MILE DOWN THE ACCESS ROAD WHEN I WENT TO BRAKE AT THE INTERSECTION. AS SOON AS I TOUCHED THE BRAKE THE ENGINE DRAMATICALLY INCREASED ITS SPEED AND THE TRUCK STARTED TO ACCELERATE. I IMMEDIATELY APPLIED FULL PRESSURE TO THE BRAKE TO STOP THE TRUCK BUT THE ENGINE WAS STILL HIGHLY REV'D AND I COULD FEEL THE TRUCK TRYING TO ACCELERATE. AS SOON AS I SHIFTED THE TRANSMISSION INTO NEUTRAL THE ENGINE REVS WENT BACK TO NORMAL IDLE SPEED AND THE TRUCK STOPPED TRYING TO MOVE FORWARD. OTHER DETAILS ARE THAT THE OUTSIDE TEMPERATURE WAS BETWEEN 10-20F, ROADS WERE CLEAR AND DRY AND THE TRUCK WAS IN 2WD. AFTER I CHECKED THE ACCELERATOR PEDAL, IT WAS FREE AND CLEAR OF ANY OBSTRUCTION THAT COULD HAVE MADE IT STICK. THE TRUCK WAS PURCHASED NEW IN OCT 2011 AND CURRENTLY HAD ABOUT 24K MILES ON IT. THE TRUCK HAD BEEN DRIVEN ABOUT 5 MILES TO THE APPOINTMENT, SAT FOR ABOUT AN HOUR BEFORE THE RETURN TRIP HOME. IT WAS FORTUNATE THAT THIS DID NOT CAUSE AN ACCIDENT. BEING AWARE OF THE PRIOR SUDDEN ACCELERATION PROBLEMS IN THE NEWS WITH TOYOTAS THIS SEEMS TO BE A CASE WHERE IT HAS OCCURRED ON A 2011 MODEL. THE FOLLOWING WEEK I SUBMITTED THIS SAME INFORMATION TO TOYOTA. *TR

HAVE NOTICED THIS ISSUE EVER SINCE PURCHASING THE VEHICLE NEW, BUT IT WAS MOST OBVIOUS ON THE FIRST LONG MOUNTAINOUS ROAD TRIP THIS WEEK: WITH CRUISE CONTROL ENGAGED WHEN BEGINNING UP STEEP INCLINES, THE CRUISE CONTROL GUNS THE ENGINE, PUSHING THE VEHICLE TO SPEEDS NEARLY 5MPH OVER THE CRUISE CONTROL SET SPEED. WAS TRAVELING INTERSTATE HIGHWAYS, SO BY "STEEP" I MEAN NOTHING MORE THAN INTERSTATE STANDARDS. IT IS AN UNEXPECTED INCREASE IN SPEED AND DANGEROUS TO THE POINT THAT I EVENTUALLY STARTED DISENGAGING CRUISE CONTROL GOING UP INCLINES. *TR

LETTER FROM SENATOR MARTIN HEINRICH RE CONSTITUENT REGARDING SAFETY OF HIS 2011 TOYOTA TACOMA (REPLY TO NEW MEXICO OFFICE). *SMD THE CONSUMER STATED THE ACCELERATOR PEDAL WAS EXTREMELY SENSITIVE, AND AT THE SLIGHTEST TOUCH THE VEHICLE WOULD PROCEED WITH FULL SPEED. THE LOCAL DEALERSHIP, INFORMED THE CONSUMER THE PROBLEM COULD NOT BE CORRECTED.

TL* THE CONTACT OWNS A 2011 TOYOTA TACOMA. THE CONTACT WAS DRIVING APPROXIMATELY 65 MPH WHEN THERE WAS A RAPID INCREASE IN ACCELERATION AND ENGINE RPMS. THE MALFUNCTION OCCURRED UNEXPECTEDLY WHEN THE CRUISE CONTROL WAS IN ACTIVATION. THE VEHICLE CAME TO A STOP ONCE THE BRAKE PEDAL WAS ENGAGED AND THEN RESUMED NORMALLY. THE VEHICLE HAD NOT BEEN DIAGNOSED. THE MANUFACTURER WAS NOT NOTIFIED OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 6,000.
