2018 TOYOTA SIENNA- Hampstead, NC
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.

2018 TOYOTA SIENNA- Goodyear, AZ
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.

2018 TOYOTA SIENNA- Lompoc, CA
The front passenger side bumper snap(s) comes undone, by air flow, as vehicle travels down the road - this causes further tearing of the supporting plastic frame. Local Toyota dealership says this initially was caused by a driver of the vehicle hitting a concrete curb. Note: Bottom of the bumper is only 8 inches from ground surface. The safety issue is: the bumper and its supporting plastic frame will eventually break and fall off vehicle while in transport. I have witnessed this several times on other vehicles (especially on Toyota's). Dealer compounds problem by saying entire bumper has to be replaced at high cost to customer. Customer delays repair (as I have). This causes further damage to the supporting plastic frame. I have gone from one snap to several snaps in duration. I sent Corporate Toyota a complaint - Essentially, they said they would not do anything .

2018 TOYOTA SIENNA- Grand Rapids, MI
When turning left in a busy intersection, our van was struck by another vehicle on the front passenger corner of the car. The strike occurred with my van going about 10 mph, the other car going about 45 mph. All of the airbags deployed. When the airbags deployed, the coverings on the lights came off and the small lightbulb and silver casing projected out, scratching my son's arm. Nothing in the vehicle should break or become a projectile when the airbags deploy. I am not certain on the last few questions.
