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.

2007 Toyota Prius with tire failure and brakes grabbing. The battery and headlights failed. The consumer stated Toyota has since removed this particular type of bulb and assembly from production. When the vehicle was 1 year old the consumer was stopped by the police and given a warning for the headlight being out. However, when the consumer and her husband exited the vehicle, they along with the police officer found both headlights were working and he let them go without a citation. The consumer has since discovered that one headlight or the other will just go out on occasion during every drive. The brightness of the headlights began to dim when the vehicle was only a year old. Toyota recommended using the headlights less and they further recommended not using the highly touted feature that allows the lights to automatically turn off after the vehicle has been turned off. Last month, the consumer received a letter from Toyota regarding information about a problem with the hid headlights. The letter stated the customer support program would reimburse for some cost relative to the defective headlights. However the local dealer did not agree and the cost far exceeded anything mentioned in the letter. The dealer informed the consumer the cost of installation for new bulbs would be $245 in labor for each headlight replacement, that was in addition to the exorbitant cost of the bulbs themselves.

1. sitting in traffic only rt. 287 N. the battery level dropped quickly and significantly to the point of my being unable to engage the electric engine which is the initial method of sending power to the wheels. 2. consequences: Bumper to bumper traffic had to be directed around me which caused more traffic and put me in danger of becoming involved in an accident. 3. investigated possible recall but none was documented.

All late model Toyota gas electric autos. I find them very dangerous in parking lots, as they can and do backup with no noise. I was almost run over by one on a foggy day last week. The driver never turned on light and didn't see me when backing out of parking spot. I was able to get out of the way that time. Suppose I had been blind? not a sound to let me know the car was there. I really think the car company should install a backup alarm of some sort on all these autos.
