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. Notes: A dependable pickup option that does have a slight history of frame corrosion. Even though mud looks cool on a truck, it's best if you run this through the car wash every now and again.

Battery drains with all electrical components shut off. If vehicle left sitting much over one week it will completely drain the battery to the point that it will no longer hold a charge. I've replaced the battery 5 times in one year and finally put a quick disconnect on the negative battery post. I've had Toyota look at it twice and they say there is nothing wrong.

Battery drains with all electrical components shut off if vehicle left sitting much over one week. After third visit to dealer, they replaced a wiring harness. The problem persists.
