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.

Head gasket leaking found 6 head bolts loose. Installed new head gasket set, new intake manifold. Paid 2000 dollars for repairs, now having problem with the engine. Makes loud noise and overheats. Mechanic and bar agent advised it was a manufacturing problem. Headbolts came loose again and now I need new engine. Previous to this my insurance had paid a total of 5000 dollars for some mechanical and body work. I have been without a vehicle for almost seven months now. Called Toyota manufacture company they told me the only way they would inspect the vehicle would be if they charged me. I do not have the money to afford the repair again and to buy a new engine. I just need it to be inspected especially since I had a government official from the bureau of auto repair confirm that there was a manufacturing defect.

The engine cover is cracked, this cover has never been removed for any type of repair. Wondering if the heat of the engine caused it to crack.

Took my car to the shop for regular maintenance and found out that my car was leaking coolant out of three head bolts on back of engine block. They were stripped out because of Toyota improper design of the block. 4 1/2" hole with 4" bolt with only the bottom 1 1/2" threaded which is only an inch to inch thread. Pour design for an aluminum block for that tensile strength. Its an 06 Scion Tc they wanted 6000 to replace block. Even called corporate but they wouldn't do anything about it since its outside of powertrain warranty when they know its a known issue. They even issued a tsb out in 3/2/2011. Something needs to be done I have seen many cases on this issue and Toyota is not willing to do anything about their problem and their pour designs. Service bulletin: S-sb-0004-11.
