2017 TOYOTA SIENNA Fuel/propulsion System Problems

October of 2024 my van stalled while I was driving. The van was towed to an auto shop. The shop suspected a battery & alternator so replaced it. Later that same week I filled my tank at Delta Sonic and immediately proceeded to the car wash. My van stalled in the car wash. Once I was pushed out I had it towed again. I drove it for a few weeks and filled up the tank at Delta Sonic but this time the van didn’t start at all. Towed the van again. Shop thinks my issue is resolved- did a complete check of everything & returned my van to me. A week or so goes by and I filled my tank late at night and it wouldn’t start after fill up. A tow was not available. Scared and frustrated I called multiple people for help. Two hours pass, before I try to start the van again. It starts. Now I am starting to correlate a fuel fill up with my van not starting after re-fueling. My safety and my grandchild’s safety was jeopardized when my van stalled while driving in an extremely busy roadway. The next time, Multiple people had to push me out of the car wash and the last time I was forced to sit at gas pumps waiting for help. I stop filling my tank to full and take the van to Toyota. They confirmed the fuel pump was the issue and fixed it.

For about five months now, when we COMPLETELY fill our gas tank (2017 Toyota Sienna) even to the point of overflowing bit, the dashboard Fuel Indicator red arrow no longer goes all the way over to the right AND the "distance until empty" mileage is much less than what it should be (ie 306 miles vs approx 440 miles). We have tried the resets, which don't work. We only use good-grade gasoline.

While traveling at a high speed, van's power train jerked hard and rapidly slowed on its own, not allowing me to excelerate. Almost rear ended by following vehicle that managed to swerve around to avoid my rapid deceleration. Check engine light came on and was hard to start. Had to allow the van to sit a while before I was able to start. Van acted like it was in limp mode. This malfunction has occurred several times. Mechanic code shows P0087 fault code. Low fuel pressure. Toyota has recalled many of these vehicles in this year for this issue, but mine seems to not be one of them. Very dangerous.

Today 4/7/23 My 2017 Toyota Sienna accelerated on its own. I was driving my 4 children to school and we were at a stop light. When I took my foot of the brake to start making a turn the car gunned it around the corner. It scared everyone in the car half to death. Thankfully no one was hurt but it looks like others on here haven't been so lucky with this issue. I hope toyota does the right thing a d fixes this issue before more people die.

The fuel pump has an issue leading to a check engine light and compromised engine performance. It has been inspected by an independent service center.

On 10/14/2021, as my wife was pulling into our attached garage, the vehicle suddenly accelerated, hitting a metal storage shelf located at the back wall of the garage. The impact of the crash caused the vehicle and the shelf to extensively damage the dry wall of that area of the garage, as well as to damage the pedestal supporting the house water heater, which resulted in the water heater detaching away from the wall and being destroyed. There was, of course, also major damage to the front bumper area of the vehicle. It is my contention that the cause of the accident lies in some component of the vehicle acceleration system. I believe this to be true because of two prior incidents which occurred within the month before this happened. On 09/16/2021, I was driving this vehicle and wanted to make a U-turn. I was traveling at approximately 10 MPH, but as I began the turn, suddenly, the vehicle accelerated to about 25 MPH, even though my foot was off the accelerator. My wife and granddaughter were in the vehicle at the time and both expressed alarm, somehow thinking I had purposely made this maneuver, which I assured them that I had not. Then, approximately 7-10 days later (I am unsure of the date), I was driving, alone, in this vehicle and went to make a left-hand turn. The vehicle again accelerated, even though I had removed my foot from the accelerator pedal and was applying the brakes. I estimate that as I began the turn, my speed was 10-15 MPH, but the vehicle accelerated to 25-30 MPH. I dismissed both of these prior incidents as not too important and attributed them to some unknown anomaly on the road. However, after the latest incident involving the damage to my garage and vehicle, research showed that several Toyota models and specifically the Sienna have had similar issues in the past. I am reporting this incident to Toyota for their evaluation, but wanted to make your agency aware, also.

Vehicle began running harshly, then stalled. Check engine light came on. Upon inspection at Toyota dealership, found to have leaked fuel into charcoal canister. Vehicle owner does NOT overfill gas tank.

TOP HINGE ON FUEL COVER DOOR BROKEN AFTER 52K MILES. FROM SEARCHING ONLINE, IT SEEMS TO BE A REPORTED ISSUE WITH THE SIENNA DUE TO REQUIRED PRESSURE TO CLOSE THE FUEL COVER DOOR.

CAR STALLS WHEN ACCELERATING FROM A STOP. HAPPENS ON HIGHWAY STOP AND GO AND WHEN ENTERING A JUNCTION AFTER A STOP SIGN. AFTER THE STALL THE CAR JERKS AS IT SUDDENLY LACKS TORQUE AND GOES TO A LOWER GEAR. TOYOTA TECHNICIAN SAID THAT TRACTION CONTROL SHUTS OFF FUEL. THIS IS DANGEROUS SINCE IT LEAVES YOU STALLED AFTER GOING INTO A JUNCTION. THEY ISSUED A TSB 0197-17 THAT DIDN'T SOLVE THE PROBLEM AND THEY CLAIM THAT THERE IS NO PROBLEM AND THAT IT IS A DRIVING STYLE ISSUE.

CAR SMELLED OF GAS FROM THE TIME I BOUGHT IT (NEW) AFTER IT WAS STARTED AND IT WAS DRIVEN FOR A FEW MILES. SITTING OVERNIGHT, THE SMELL WOULD DISSIPATE, BUT THE SAME THING HAPPENED EACH DAY -- STRONG GAS SMELL AFTER A FEW MILES OF DRIVING . COLDER WEATHER, THE SMELL WAS MORE PRONOUNCED. DEALER DIDN'T SEE ANY DRIPPING GAS, SO SENT ME HOME TWICE WITHOUT REPAIRS BEING DONE. AFTER THEY KEPT IT OVERNIGHT, THEY SMELLED THE SMELL IN THE MORNING AND ONLY THEN DECIDED TO CALL TOYOTA WHO SAID THERE HAS BEEN A FEW PROBLEMS WITH INJECTOR SEALS. IT WAS REPAIRED AND IS FINE NOW. MY DAUGHTER'S FRIEND HAD THE SAME 2017 SIENNA AND IT CAUGHT FIRE ON THE HIGHWAY AND EXPLODED --- MY GUESS IS THAT THERE IS A VERY SERIOUS ISSUE HERE THAT NEEDS TO BE ADDRESSED.
