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.

I feel that this key problem falling out of the ignition, key will not turn on or off making it hard to control when the key is in the ignition and causing it not to start. I had this same problem on a 2003 Isuzu ascender. Also the "driver information center" has quit working right which controls a lot of things on the vehicle. I think it is a defective switch from GM who also built my 2003 Isuzu.

I own a 2004 Hummer H2, and my boss owns a 2003, and my brother also owns a 2004, and all three (3) trucks have the same problem with the running boards rusting and also the wheel wells. For the money that you pay for a truck it shouldn't be rusting out, I hope that you could address this problem, I had brought my truck in for service and there was nothing they could do they gave me this site. Please contact me at your earliest convenience. Thanks for your prompt attention to this matter.
