2017 Toyota Sienna: fuel pump failure

Filed Aug 31, 2026 · Body · FL

The fuel filler door assembly on this 2017 Toyota Sienna failed structurally due to a defective hinge mechanism. This defect directly compromises a critical vehicle safety system. The Sienna is engineered with a physical safety interlock cable that links the fuel door to the driver-side sliding passenger door. This system is designed to prevent the heavy power-sliding door from operating while the fuel cap is off, protecting occupants from injury and preventing the door from violently striking a gas station fuel pump nozzle during refueling. Because the fuel door assembly failed, the safety interlock mechanism was compromised, presenting an immediate risk of fuel pump damage, fuel spillage, or passenger injury from the sliding door. Toyota corporate previously issued a Customer Satisfaction Program (CSP) to address this specific structural defect. However, my local franchised Toyota dealership refused to preform comprehensive repair, claiming they "only cover the pin". This dealer non-compliance forced me to seek immediate out-of-pocket repairs at an adjoining facility to restore the vehicle's structural safety interlock system. Toyota Corporate is refusing to remediate this safety-related failure. I have made several attempts to resolve this directly with Toyota Corporate (6 or more), without success. This included several phone calls, and a letter written to the Toyota Brand Engagement Center, which went unanswered.

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.

Subject: Safety Defect Complaint – 2017 Toyota Sienna (VIN: [XXX] ) Safety Division, I am submitting a safety complaint regarding my 2017 Toyota Sienna, VIN [XXX] . In June 2023, while traveling on I-81 South in Virginia with my family of seven, the van stalled suddenly and emitted white smoke from under the hood, then the engine completely failed. The vehicle had only 111,000 miles. The repair would have cost $15,000, and I had to sell the van in 2024 for $4,000, suffering significant financial loss. Toyota informed me no recall applies to my VIN, although many 2017 Siennas experienced fuel pump failures causing stalling. As a person with disability and serious health issues, this incident caused extreme stress, hardship, and risk to my family. I request that the federal safety agency investigate this potential safety defect to determine whether other 2017 Siennas are affected. Sincerely, Your Name Phone Number Address INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

At 70000 miles and around 9/1/2023, started to notice our brake stop suddenly steep down pedal when braking at 45mph or higher. Problem starts after fuel pump replacement recall completed by dealership August 2023. Check recall and campaign program, my vehicle VIN specifically not on the recall list for brake booster vacuum pump. I thinks Toyota HQ should take my vehicle into consideration since my vehicle is a 2017 Sienna. Contact HQ they refused to offer to diagnosis nor help replace if applicable. Due to your vin not on the recall, your on your expense.

Vehicle exhibits periods of rough acceleration, chugging, and hesitation. After 3 trips to different toyota dealers they refuse to address problem. A massive recall of toyota fuel pumps is underway on several vehicles including 2017 sienna's but dealerships claim my 2017 sienna is not on list. I've lived with this for 3 years and my vehicle is till under warranty with less than 18,000 miles on it. Happens whenever vehicle is used. Dealerships won't test it as they have to drop gas tank.
