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.

tHIS IS THE SECOND TIME IN 3 YEARS THAT THE COOLING SYSTEM FAILED. i BOUGHT THIS CAR IN SEPTEMBERT OF 2009, AND HAD TO REPLACE HE HEAD GASKET DURING THE SUMMER OF 2010. Now i get a check enging ligfht and when i bring it in the heads are already cracked! It seems like this vehicle had a design flaw that causes head gasket failure and fatal over heating fairly quickly. I have heard that there are intake valve problems. Could this result in head gasket failure?? Why wasn't I notified about the intake valve problem?? Pontiac/GM never ever notiofied me that this might be an issue. I had to find the info myself via the internet.
