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 contact owns a 2008 Toyota Prius. The contact stated that the check engine warning light remained illuminated. An independent mechanic diagnosed that the coolant control valve needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 150,000.

While my 2004 Toyota Prius was in the shop for its 30,000 mile maintenance, my mechanic found that the water pump has been leaking coolant (photos available). The car has only 21,600 miles, and its water pump should last at least three times as long. My local berkeley Toyota dealer had three ┐04 Prius pumps on hand which is indicative that many Prius┐ are experiencing such a water pump failure. I┐M writing to inform you of what appears to be a substandard part on 2004 Prius┐.
