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.

8/26/14 mechanic found bad water pump/ ac blowing warm - recharged system, on 8/27 made clacking sound. 8/28 went 10 miles at 70 mph. On off ramp of freeway car started smoking, air went completely warm, battery light and heat indicator light came on. Pulled into parking lot & had to be towed. 8/29/14 second mechanic found ac compressor had to be replaced. Plastic brace that supported belts connected to the ac compressor had broken off and wrecked the compressor. Said could have caused much more damage. Should the water pump and ac compressor have gone at 51,000 miles? all maintenance had been done regularly. This is much too early for these parts to have gone bad.

2011 Scion Xb abrupt throttle response off idle. Vehicle "jack rabbits" to accelerate. Very hard to accelerate slowly and safely. Can be dangerous in traffic and parking lots. You have to keep your left foot hard on the brake. Toyota refuses to acknowledge responsibility for the problem.
