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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

The navigation, bluetooth & radio system was turned off on it own and became corrupted when the car dealership tried to update the systems software. The hardware was then rendered inoperable and the systems computer was then replaced, the warranty did not cover the defects in the system. The estimated repair exceeded $1000us. Due to the dealerships actions in trying to run a software update, the repair costs were paid by the dealership. The failure of the computer system seemed to be known by the car dealer. Toyota was never directly contacted by car owner as only the car dealer handled the repair issues.

Driving in the evening, using headlights. Turn vehicle off and exit. Within an hour, get back into vehicle, start, turn on headlights and they (low beams) fail to illuminate. High beams work, as do parking lights, but the low beams stopped working, and they still fail to work. Driving without headlights or perpetual use of high beams is a safety hazard and distraction for other motorists causing an unsafe condition. Have made an appointment with local Toyota dealership for maintenance, in early Feb. 2014. The vehicle is still under factory warranty, less than 36 months old with fewer than 36,000 miles.
