Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Complaint: Toyota Sienna 2011 SE on 2/3/2016 I took my 2011 Sienna to the local Toyota dealership because the information display screen indicated vsc system warning and the engine light, trac system light, and warning lights were on. After diagnostics the service advisor explained that fuel emission switch valve was stuck in the off position. The technician report identified the part as P2440 evaporative emission pressure switch valve. The switch regulates the amount of gasoline pumped into the tank through the intake and outtake of air. Vacuum hoses connect the valve to a ┐charcoal canister┐ which collects gas fumes from the tank and routes them to the engine for combustion. Unfortunately, Toyota sells these various components in emission system as one unit. The part was $537.92 and $148.88 for labor. The suggested cause was overfilling the gas tank. We have never had a problem filling up tanks (stopping before the point of overflow) with many previously owned Toyota trucks and sedans. The core of my grievance is the fact that the owner's manual does not specifically caution the owner that this practice can damage or cause a malfunction of the emission system. The manual only cautions the person pumping fuel ┐do not spill fuel during refueling.┐(P.150 in refueling section). If this was the real cause for the needed emission part replacement I hope that Toyota will write a clear warning about the consequences of "filling up" in their manual or consider redesigning the emission system. Perhaps this complaint will prevent another Toyota customer the cost and dissatisfaction of this same experience.

The weld at the top of the hinge on the fuel filler door has broken, so the door will not close. This prevents opening the sliding door on the driver's side. I have children and would need the ability to evacuate passengers quickly and easily in the event of an emergency. One of my passengers is restrained in a car seat that I need to activate in order to remove the child from the car. The door cannot be opened more than a few inches with the broken fuel filler door as an obstruction, so it creates a major safety issue.

I stopped for gas and was unable to open the fuel filler door. Because of the fuel filler door failure, I was not able to open the driver side passenger door. I drove the vehicle home and upon further investigation, I discovered the top fuel filler door hinge was broken free. The broken hinge allowed the passenger door activation switch located behind the fuel filler door to pop out which de-activated the passenger door operation. In the event of an accident, the driver side passenger door would not be able to be opened.
