2014 Toyota Sienna Engine

Timing chain cover leaking oil. This is known issue on 3.5L V6 model years 2011 -2022

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.

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. ADDITIONALLY THE SPEED CONTROL WAS NEVER ACTIVATED WHEN ISSUE OCCURRED.
