Hi, I’d like to report a serious issue with my 2018 Toyota Sienna related to the recent fuel system recall. Since the repair, the vehicle has leaked all of its gasoline not once, but three separate times. One of those times, my family was inside the vehicle, and the smell of gas was overwhelming. The car wouldn’t start, and it was clearly an unsafe situation. Now the dealership is charging me $1,400 to replace the fuel pressure hose and clamp, which, after thorough research and review, appears to be directly related to the process they followed when replacing the recalled fuel pump. I’ve also tried contacting the service manager, but I haven’t received a call back. That’s why I’m now requesting that Toyota open a formal case to investigate this properly. I believe this repair should be covered, and I’m asking for support from Toyota directly.
The fuel line under the intake ruptured when I started my car on 2/21/23. The repair shop said they had never seen one fail like this. I do not have the parts. I was fortunate to be at home and that the engine wasn't hot when this happened so there was no fire. I had an issue starting the car ~ 1 month before that, but I don't know if the issue was fuel related. The car had been sitting for 1 week prior to that issue.
Car stalled, sputtered and died. At first, I thought I was out of gas. After several tries, the car started and went 3 miles to gas station. After getting gas, the car wouldn’t start several times and that same day the check engine light came on. We took it to Autozone to check the code and they said it was showing fuel pump failure. Today I’m taking it in to the dealer for service. It has started and run twice since the initial episode.
When accelerating, both from a stop and/or at speed, there is a definite hesitation. When gas pedal is pressed down, there is a noticeable pause before acceleration begins. This causes safety issues especially when accelerating to merge with moving traffic. Have owned this van since Oct 2021, and it has always been an issue. Possible fuel filter problem. Have not reported issue to dealer. Currently under extended warranty.
