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.

  • 55,000 miles
With only 55,000 miles, the exhaust manifold cracked. Seeing all of the complaints online and talking to my mechanic, this seems to be a default part. Chevy should be recalling these. My mechanic had to order the part through the dealer and they had the replacement manifold in stock. Exhaust manifolds are not normally stock items unless there is a real high need to replace them.......
