2017 Toyota Sienna fuel system problems

Filed Jun 22, 2026 · Fuel system · FL

While driving at speed, the vehicle suffered a sudden and complete loss of engine power and stalled in traffic. The vehicle was diagnosed by an independent mechanic who found a failed factory-installed Denso fuel pump module. This failure mirrors Toyota Safety Recall 20TA02 (the federal safety agency Campaign 20V012) for the exact same model year 2017 Toyota Sienna, but my specific VIN is currently excluded from the recall list. The un-recalled defective component created an immediate highway safety hazard as me and my family were left stranded in the middle of the road. We waited for hours at the risk of oncoming traffic until we were able to have a tow truck lift the van and take to the nearest repair facility (an independent service center - Goodyear Auto Service). The repair facility diagnosed the problem and confirmed that the fuel pump failed to generate enough pressure causing the vehicle to stall and not start again. To correct the problem, the fuel pump was replaced with an OEM toyota fuel pump module assembly.

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.
