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.

Check engine light comes on and engines goes into reduced power mode. Doesn't have enough power to go over 40 mph. While pulling a trailer the engine doesn't have enough power to climb hills or go over 25 mph. I have taken to dealer twice and they say GM is aware of the problem but they don't have a fix for it. It's not safe having a vehicle that breaks down in -15 degree weather and having the dealer tell you that there is no fix for the problem and to just keep driving the vehicle.
