2015 Toyota Sienna Engine Problems

i am having repeated issue with Toyota sienna engine 1. Engine oil leaks through timing chain cover 2. Engine coolant leak Engine oil leak keep repating even I fixed earlier and leaks again due poor engine design same issue fixed on Nov/22/20 - 59k

My engine caught on fire. We had seconds to get out prior to it engulfing in flames. Fire department had to extinguish. Not sure what caused it. The entire vehicle caught on fire. There was an engine light warning I had the vehicle repaired but the warning light was not cleared

The intake valve became burnt/stuck, causing my car to lose all compression on cylinder 3. The CEL came on, flashing, and the car immediately started driving rough and not accelerating. I had the vehicle brought to 2 different auto shops that confirmed the issue. My and my childrens' safety were at risk as soon as we tried to turn right onto a high speed road and my car started the flashing CEL and would not accelerate. There was no warning before this incident.

The contact owns a 2015 Toyota Sienna. The contact stated while starting the vehicle he noticed that the vehicle was shuddering and shaking uncontrollably. The check engine warning light was illuminated. The contact attempted to restart the vehicle however, the failure persisted. The contact took the vehicle to an independent mechanic to be diagnosed. The contact was informed that the failure was due to low cylinder pressure on cylinder #6. The mechanic was not able to do the repair on the vehicle, so the contact took the vehicle to the local dealer who diagnosed and confirmed the failure as a misfire and low-pressure cylinder #6 and that the spark plug was damaged. The vehicle was repaired however, the failure persisted. The dealer recommended that the engine be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 87,000.

WHEN THE CAR IS AT IDLE SPEED, SUCH AS WAITING FOR TRAFFIC TO CLEAR FOR A LEFT TURN, THE CAR WILL JUST DIE WITHOUT WARNING. IT WILL USUALLY RESTART RIGHT AWAY, BUT THIS HAS NEARLY CAUSED A COLLISION. THE DEALERSHIP IN BELLEVUE, WA SAYS THAT'S A NORMAL THING IF THE CAR ISN'T PROPERLY MAINTAINED. I HAVE BROUGHT THE CAR TO THAT DEALERSHIP FOR ALL BUT ONE OF THE MAINTENANCE INTERVALS, AND THE ONLY OTHER TIME WAS FOR MAINTENANCE WHEN WE WERE IN OHIO. HAVING THE THROTTLE BODY CLEANED IS NOT ON THE ROUTINE MAINTENANCE SCHEDULE. WHEN THE CAR DOES DIE THERE ARE NO CODES OR OTHER SYMBOLS THAT COME UP ON THE DISPLAY, OTHER THAN TO SAY THAT THE CAR DIED.
