2014 TOYOTA SIENNA Engine Problems

The contact owns a 2014 Toyota Sienna. The contact stated that while driving 70 MPH, there was an audible alarm coming from the vehicle, alerting the contact that the door was ajar. The passenger’s side slide door opened independently while the vehicle was in motion. The vehicle was modified to accommodate a ramp for the contact's two wheel-bound children. The contact pulled over to the side of the road and closed the sliding door. The contact's husband tied the door to prevent it from opening independently again. The check engine warning light was intermittently illuminated. The vehicle was taken to the dealer, where it was inspected. The contact was informed that two latches had corroded and needed to be replaced. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 16V858000 (STRUCTURE). However, the VIN was not included. The manufacturer was not made...

I have 2014 Toyota sienna head gasket problem with less than 100,000 k

Was driving my sienna down he highway, as I was passing someone I lightly accelerated and I heard a loud bang sound. Seconds later I see smoke coming out of the hood so I pull over, about 30 seconds before I pulled over the engine bursted into flames. When the vehicle came to a stop it would not unlock and me and my 2 kids were stuck in a burning vehicle, we barley made it out and my arm got burnt from it, this is the 4th time I’ve had a problem with the engine and 6th time the transmission has had problems. I’ve heard this happen on many other siennas yet it’s not recalled…

The Toyota 2GR-FE 3.5L V6 engine have a verry comoon complaint of Blown Head Gasket under 100K miles. i own a 2014 sinenna and currently experiencing same issue at 89K miles. i looked online and found that so many people had the same issue and there was no action from the side of the company, they just waited for the 60K miles/5 year to be over so that they can deny the claim. the funny thing is that my vehicles's previous owner purchased an extended warranty which is still valid till September 2022 and the Company doesn't want to honor it. with this issue in mind i cannot take my vehicle for a long with my family, it puts life of my family at risk.

AFTER A SHORT 10-MIN DRIVE, PARKED THE VAN IN MY HOUSE'S DRIVEWAY. wHEN I STOPPED, SMOKE STARTED COMING OUT OF THE HOOD. WHICH DEVELOPED INTO FLAMES AND THE FRONT OF THE VAN WAS ENGULFED IN FLAMES. iMMEDIATELY CALLED THE FIRE DEPARTMENT TO PUT THE FIRE OUT. VAN IS TOTALY BURNT. MANAGED TO MOVE TWO OTHER VEHICLES AWAY FROM THE BURNING VAN. ALUMINUM SIDING NEXT TO THE GARAGE SUSTAINED HEAT DAMAGE.

AFTER ABOUT 60,000 MILES MY CHECK ENGINE LIGHT ILLUMINATES WITH CODE P0012 EVERY 1,000 MILES AND WHEN I TAKE IT TO TECHNICIAN THEY FIND NOTHING WRONG AFTER RESETTING. THEN AGAIN IT RANDOMLY APPEARS AND HAS BEEN DOING SUCH FOR THE LAST 10,000 MILES. FRUSTRATING. ALSO THE FRONT BRAKES SQUEAL EVERYTIME I TOUCH THE BRAKE PEDAL REGARDLESS OF WHICH PADS I USE OR IF THEY ARE NEW OR USED.

VEHICLE STOPPED ABRUPTLY WITH A SHAKE WHILE REDUCING SPEED AT A TRAFFIC SIGNAL. I WAS IN THE MIDDLE OF THE ROAD. A MILD BURNING SMELL CAME OUT FROM THE HOOD. THE CAR WAS SERVICED ONE MONTH BACK AND AS PART OF IT THEY DID 128 POINT( DO NOT REMEMBER EXACT NUMBER ) AND ALL REPORTED ISSUES WERE FIXED. AROUND $1000/- WAS SPENT ON THE CAR. SINCE BATTERY WAS JUST 1 YEAR OLD, I DID NOT EXPECT A PROBLEM WITH THE BATTERY AS WELL. STILL I SWITCHED OFF ALL LIGHTS AND TRIED TO RESTART. THERE WAS NO FURTHER RESPONSE FROM THE VEHICLE. I WAS BLOCKING TRAFFIC FROM BEHIND AND POLICE CAME TO CONTROL TRAFFIC. ONLY OPTION WAS TO TOW THE VEHICLE. I TOOK IT TO THE SAME TOYOTA AUTHORIZED SERVICE CENTER WHERE I DID THE PREVIOUS SERVICE ( I HAD PURCHASED THE CAR FROM THE SAME DEALER ). NEXT DAY TOYOTA...

AS CITY STREET BRAKING DECELERATION IS ENDING, THE ENGINE SUDDENLY SURGES AND ACCELERATES RPM. I MUST IMMEDIATELY APPLY HARD PRESSURE ON BRAKE PEDAL TO PREVENT VAN FROM SURGING AHEAD AND ALSO IMMEDIATELY MOVE AUTOMATIC SHIFT LEVER TO NEUTRAL TO DISENGAGE POWER TRAIN. AFTER ABOUT 2 SECONDS THE RPM ACCELERATION WILL STOP AND RETURN TO NORMAL. TOYOTA DEALER CHECKED ISSUE MULTIPLE TIMES, FINDING NO ISSUES. THIS IS A RANDOM OCCURRENCE THAT STARTED SHORTLY AFTER PURCHASE AND CONTINUES TO THIS DAY AND I'VE COME WITHIN INCHES OF SMASHING INTO VEHICLES IN FRONT OF ME. I REPORTED TO TOYOTA CORPORATION BUT THE OMBUDSMAN BLEW ME OFF SAYING THERE IS NO KNOWN SUDDEN ACCELERATION ISSUES. NO OFFERS TO RESOLVE FROM TOYOTA. THIS HAS HAPPENED SO MANY TIMES, I CAN NO LONGER REMEMBER THE INITIAL DATE AND EXACT MILEAGE THIS ISSUE STARTED TO OCCUR OTHER THAN WITHIN THE FIRST 4 TO 6 MONTHS OF PURCHASE....

LOSS OF ACCELERATION AFTER BRAKING. VEHICLE WILL CEASE RESPONDING TO THE ACCELERATOR PEDAL AFTER BRAKING, WILL CONTINUE TO GO SLOWLY (~20 MPH) FOR 3-5 SECONDS, THEN ACCELARATION WILL RESUME. HAPPENS AT ANY TIME IN ANY SITUATION; BRAKES JUST HAVE TO BE TAPPED TO LOSE ACCELERATION, HAS BEEN HAPPENING SINCE VEHICLE NEW.
