2011 Toyota Corolla Speed Control & Cruise Problems

TL* THE CONTACT OWNS A 2011 TOYOTA COROLLA. THE CONTACT STATED THAT THE VEHICLE INDEPENDENTLY ACCELERATED WHILE DRIVING AT AN UNDISCLOSED SPEED, WITHOUT WARNING. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED NOR REPAIRED. NEITHER THE DEALER NOR THE MANUFACTURER WERE NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 80,000.

TRANSMISSION: MY 2011 TOYOTA MATRIX JERKS AND ACCELERATES SUDDENLY WITH A REVVING NOISE AND MAKING CHOKING SOUNDS LIKE GEARS SHIFTING IN A MANUAL TRANSMISSION CAR. THIS HAPPENS EACH TIME I SLOW DOWN TO MAKE A TURN (LEFT OR RIGHT) OR MERGE INTO THE FREEWAY, WHEN I SLOW DOWN AT A TRAFFIC LIGHT AND TRIES TO TAKE OFF AS THE LIGHT TURNS GREEN, AND WHEN I SLOW DOWN AND TRY CHANGING LANE TO PASS ANOTHER VEHICLE. I HAVE HAD TO PRESS HARD ON THE BREAKS TO AVOID HITTING ANOTHER VEHICLE IN FRONT OF ME. THIS HAS BEEN GOING ON SINCE I STARTED DRIVING THE CAR AFTER TAKING OVER FROM MY DAUGHTER ONE AND A HALF YEARS AGO. THANKS YOU.

THE ACCIDENT HAPPENED IN THE HOUSE-ATTACHED GARAGE. I ALREADY ENTERED THE GARAGE, AND THE CAR IS ALMOST STOPPED. THEN I NEED TO HIT THE BRAKE THOROUGHLY TO FULLY STOP THE CAR. I HIT THE BRAKE PEDAL HOWEVER THE CAR ACCELERATED SUDDENLY, JUMPED AHEAD AND CRASH INTO THE HOUSE WALL. EVEN THOUGH EVERYTHING HAPPENED IN A SECOND, I'M SURE THAT IT IT THE LARGER PEDAL(WHICH IS THE BRAKE) I ENGAGED WITH IN THAT SECOND. I HAVE DRIVEN THIS CAR FOR 3 YEARS, AND PARKED IN THIS GARAGE FOR MONTHS. SO I'M PRETTY FAMILIAR WITH THE CAR AND THE PLACE. LUCKILY, THERE IS NO PEOPLE GOT INJURED, AND THE AIR BAG DIDN'T EXPLODE. THE WALL WAS HIT SIGNIFICANTLY, AND THE FRONT OF MY CAR WAS DAMAGED.

I DRIVE QUITE A BIT AND NORMALLY KNOW MY VEHICLES PRETTY GOOD. I HAVE RECENTLY OBTAINED THIS 2011 TOYOTA COROLLA S AND IT IS IN GREAT CONDITION OVERALL. I MADE A TRIP 2 DAYS AFTER GETTING THE VEHICLE AND IMMEDIATELY NOTICED A HESITATION BETWEEN 55-65 MPH. THE FIRST TIME IT WAS APPROXIMATELY 11AM IN THE MORNING AT 78F. DRIVING ON A FLAT WELL MAINTAINED BLACK TOP ROAD THE VEHICLE DOES IN FACT HAVE A CONSTANT HESITATION THAT DROPS APPROXIMATELY 1000-2000 RPMS WITH A NOTICEABLE FEEL IN THE VEHICLE. IMMEDIATELY (3-4 SEC) AFTER THE HESITATION THE VEHICLE RECOVERS BACK TO THE ORIGINAL RPM. AS LONG AS STAYING IN THIS SPEED RANGE (55-65 MPH) THE VEHICLE HAS THE HESITATION REPEATEDLY. THE SECOND ISSUE THAT I HAVE NOTICED ON THE SAME VEHICLE IS THE ACTUAL DECELERATION WHEN REMOVING MY FOOT FROM ACCELERATOR. WHEN TRAVELING ON THE SAME ROAD AND TIME AS STATED ABOVE THE VEHICLE SEEMS TO REALLY COAST RIGHT ALONG OR SO IT SEEMS. WHEN SAYING THIS, I REMOVED MY FOOT FROM ACCELERATOR AND THE VEHICLE ROLLS RIGHT ALONG AS IF I AM STILL PUSHING THE ACCELERATOR AT WHICH TIME I MUST APPLY THE BRAKE MORE SIGNIFICANTLY THAN LETTING IT JUST COAST. I WOULD LIKE TO KNOW HOW THIS IS EFFECTING MY GAS MILEAGE, IS IT GOING TO CAUSE UNDUE STRAIN ON THE DRIVETRAIN, IS THIS GOING TO BE A PROBLEMATIC ISSUE THAT TOYOTA IS GOING TO CONTINUE TO IGNORE?

I'M A 52 YEAR OLD MALE DRIVER AND THE CAR IS A 2011 TOYOTA COROLLA AUTOMATIC DRIVE. THE TEMPERATURE WAS 4 DEGREES FAHRENHEIT. I ACCELERATED FROM A STOP TURNING LEFT ON TO A RURAL ROUTE HEADING WEST. THE ACCELERATOR DROPPED TO THE FLOOR GOING FAR BEYOND WHERE I PUSHED IT WITH MY FOOT. I HAD TO STOMP THE BRAKE SO IT WOULD RELEASE THE ACCELERATOR AS IT ALREADY ACCELERATED BEYOND SAFE SPEEDS. THE ACCELERATOR WASN'T STUCK IN A FLOOR MAT AS IT RELEASED WHEN I STOMPED THE BRAKE. THE 2011 COROLLA OFTEN EXHIBITS AN AUTO-PILOT FEELING ON A FLAT STRETCH OF ROAD OR GOING DOWNHILL AT WHICH YOU CAN REMOVE YOUR FOOT FROM THE ACCELERATOR AND IT WILL MAINTAIN THAT SPEED FOR ANOTHER MILE OR SO RATHER THAN DECELERATING. DURING THIS TIME, THE BRAKE STIFFENS AND THERE SEEMS TO BE A STRONG UPWARD FORCE ON YOUR FOOT AS YOU TRY TO DEPRESS THE BRAKE PEDAL. DEPRESSING THE BRAKE PEDAL DOESN'T DECELERATE THE VEHICLE VERY MUCH. IT APPEARS TO TRY TO CONTINUE THE SPEED THE AUTO-PILOT CHOSE. WHEN THE AUTO-PILOT ISN'T EXPERIENCE, THE BRAKE PEDAL IS NORMAL AND GOES DOWN WHEN DEPRESSED AS YOU WOULD EXPECT. I HAVE TRIED TO DOWNSHIFT TO FORCE DECELERATION AS WELL BUT SHIFTING INTO THIRD DOES NOT RESET THE AUTO-PILOT. SHIFTING INTO SECOND MIGHT RELEASE THE AUTO-PILOT BUT I BELIEVE THAT IS DANGEROUS TO THE OCCUPANTS AND HARMFUL TO THE TRANSMISSION SO I HAVE NOT TRIED SHIFTING INTO SECOND. I'M QUITE CONCERN THAT THIS WILL LEAD TO AN ACCIDENT. NOTICING ON OTHER INTERNET SITES THAT PEOPLE HAVE CLAIMED THIS WAS AN ISSUE WITH THEIR 2011 COROLLA, I THOUGHT I SHOULD ADD MY EXPERIENCE IN HOPES TO SEE A RECALL. *TR

I WAS GETTING OUT A PARKING IN REVERSE, SUDDENLY THE CAR ACCELERATED WITHOUT CONTROL CRASHING WITH THE CAR WAS BEHIND IN THE OTHER EXTREME IN THE PARKING. DAMAGES:1-BUMPER, RIGHT AND LEFT OF THE REAR SIDES OF MY CAR 2-BACK, FRONT, AND SIDES OF THE CAR WHICH MY CAR STOPPED. *TR

I WAS GOING TO AN ATM AT ABOUT 8 MPH WHEN THE CAR ACCELERATED AND I WAS NOT ABLE TO STOP IT BY PRESSING THE BRAKE. THE CAR JUMPED A CURB, WENT THROUGH A HEDGE TO A FIELD, UP A HILL, HEADING AT 90 DEGREES TO A FOUR LANE HIGHWAY. I MANAGED TO STEER THE CAR TO GO PARALLEL TO THE HIGHWAY WHEN THE CAR REACHED THE HIGHWAY CURB. THE CAR THEN STOPPED. THREE TIRES WERE BLOWN AND THE CAR INCURRED BODY DAMAGE. *TR

ONCE A MONTH OR SO WHEN I AM AT HIGHWAY SPEEDS THE CAR DOES NOT DECELERATE AS NORMAL WHEN I TAKE MY FOOT OFF THE GAS PEDAL. THE CAR TEND TO STAYS AT THE SPEED IT WAS AT UNTIL I USE THE BREAK. IT IS ALMOST LIKE THE CRUISE CONTROL HAS BEEN TURNED ON WITHOUT NOTICE (IT IS NEVER TURNED ON DURING THESE CASES). THIS SOMETIMES INCLUDES THE SLIGHT ACCELERATION LIKE SOME CAR GET WHEN THEY ARE GOING BACK ON CRUISE CONTROL. LUCKILY I KEEP A GOOD DISTANCE BETWEEN ME AND THE CAR AHEAD OF ME. I CAN SEE THIS ISSUES CAUSING ACCIDENTS. *TR

2011 TOYOTA COROLLA. CONSUMER WRITES IN REGARDS TO VEHICLE SUDDEN ACCELERATION. *SMD THE CONSUMER STATED WHEN HE REMOVED HIS FOOT FROM THE ACCELERATOR, THE ENGINE WOULD SOMETIMES CONTINUE RUNNING AT THE SAME RPM, NOT DECREASING AND COASTING AS HE WOULD EXPECT. AS TIME PROGRESSED, THE ISSUE BECAME MORE FREQUENT AND THE DECREASE IN RPM SOMETIMES CAME 30 SECONDS AFTER PRESSURE WAS LIFTED FROM THE ACCELERATOR PEDAL. *JB

ON APRIL 19TH, 2014, AT ABOUT 1:30 PM, MYSELF AND MY WIFE LEFT OUR FRIEND'S HOME IN LOS ALTOS HILLS, CA. AS WE LEFT THE DRIVEWAY AT ABOUT 5 MPH ON BAKER LN, THE CAR WENT INTO A SUDDEN, UNCONTROLLABLE ACCELERATION MODE, REACHING SPEEDS 50 - 60 MPH. WITHIN ABOUT 1000 - 1500 FT WE APPROACHED A THE INTERSECTION OF BAKER LN AND PURISSIMA RD., ALL THE WHILE DESPERATELY TRYING TO PRESS THE BRAKE, APPLYING HAND BRAKE AND SHIFTING TO NEUTRAL. AGAINST THIS SUDDEN BURST OF ACCELERATION, THE CAR WENT OFF THE ROAD AT THAT INTERSECTION, AND FELL INTO A DITCH AND STOPPED BY A TREE TRUNK. BOTH OF US WERE INJURED WITH MULTIPLE INTERNAL/ EXTERNAL FRACTURES, BUT WE WERE CONSCIOUS; MY WIFE IN THE PASSENGER SEAT HAD MORE GRIEVOUS INJURIES, INCLUDING AN OPEN WOUND OF BROKEN BONE IN ANKLE AND SEVERE SPINAL CORD INJURIES, AND WAS SCREAMING WITH PAIN. ONCE I COLLECTED MYSELF, I CALLED 911 AND THE FD/ PARAMEDICS RESPONDED AND WE WERE HAULED FROM THE DITCH BY CUTTING OPEN THE CAR DOORS. WE WERE TRANSPORTED TO STANFORD MEDICAL CENTER IN PALO ALTO, AFTER WHICH WE WERE SHIFTED TO OUR HMO, AFTER ABOUT 10 DAYS IN ICU. I AM NOW DISCHARGED AND REHABILITATING/ GETTING PHYSICAL THERAPY AT HOME, WHILE MY WIFE IS STILL AT A REHAB CENTER, OVER 10 WEEKS AFTER THE ACCIDENT. AT THE TIME OF THE ACCIDENT, THE WEATHER, VISIBILITY AND ROAD CONDITIONS WERE EXCELLENT; BOTH OF US HAD OUR SEAT BELTS FIRMLY IN PLACE; NO CELL PHONE WAS BEING USED; I HAD MY FOOT ON THE BRAKE AND OFF THE ACCELERATOR ALL THE TIME; AIR BAGS DEPLOYED AS EXPECTED. SINCE BOTH OF US WERE CRITICALLY INJURED, WE COULD NOT INITIATE/ PURSUE ANY LEGAL ACTION AGAINST TOYOTA AND SURRENDERED THE VEHICLE (WHICH WAS TOTALED) TO MY INSURER, FARMERS. WE STRONGLY FEEL THAT TOYOTA IS FULLY RESPONSIBLE FOR THE DEFECTIVE ACCELERATION SYSTEM AND CAUSING SERIOUS BODILY INJURY AND MENTAL TRAUMA FOR BOTH OF US. WE SHOULD BE COMPENSATED BY TOYOTA. *TR

WHILE TRAVELING ON HIGHWAY AT 65 MILES PER HOUR WHEN I RELEASE THE GAS PEDAL THE VEHICLE CONTINUES ACCELERATED FOR ABOUT ONE MINUTE AND THEN I NOTICED THAT THE RPM AND THE ENGINE START TO REDUCE SPEED. *TR

I PURCHASED THIS CAR AS A NEW VEHICLE. EVER SINCE I HAVE HAD IT THERE HAS ALWAYS BEEN AN ACCELERATION ISSUE TO WHERE IT DOES NOT SLOW DOWN FOR SEVERAL SECONDS AFTER RELEASING YOUR FOOT FROM THE GAS. IT ACCELERATES OFTEN TO WHERE YOU HAVE TO APPLY THE BRAKES FIRMLY TO WHERE THE ANTI LOCK THEN KICKS IN. DURING SERVICING IT HAS BEEN BROUGHT TO THE ATTENTION OF THE DEALERSHIP BUT THEY HAVE CONTINUED TO SAY THAT THERE IS NOT AN ISSUE. I HAVE HAD OTHER FAMILY MEMBERS OPERATE MY VEHICLE TO VERIFY THAT THIS ISSUE IS IN FACT AN ISSUE AND THEY EXPERIENCED THE SAME SITUATION. THIS IS VERY DANGEROUS AND WILL END UP COSTING SOMEONE THEIR LIFE DUE TO THE MANUFACTURERS DRAGGING THEIR FEET ON ADDRESSING THE ISSUE. *TR
