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.

Print this page Notes: The 2009 Silverado has no defect trends, which is a very good sign now that it's more than a few years old.

A couple model years back, the 2007 Silverado has an oil consumption defect at low mileage (~50k miles) — so far there's only a very few reports of the same problem with the 2009 Silverado.

The 2009 Silverado received poor side impact ratings on models not equipped with the optional side air bags.

Driving down highway, check engine light pops up, tractions control indicator light, along with digital display saying several things. Such as, engine reduced power, service traction control soon..........pulled over, had a very rough idle. Made it to parts store and have the truck scanned. Turns out it need the throttle positioning sensor needs replaced. Had them clear the code, drove few more miles and all happens again.
