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.

Problems with train mission. I'm a 75 year old driver. Bought Avalanche sly model. Great vehicle and driven easy and is garage kept. Have extended warranty from dealer. Transmission starting to bump as if you could have hiit a speed bump coming out of low into second. Was immediately taken to the dealership. They changed the wiring harness on the transmission. Said it seemed ok. As I picked up vehicle. The first traffic light caught and as I started up at a slow take off it was doing the same problem. Will return to dealership in the morning. Wiring harness fluid and filter change. Total repair to date $596

At 73000 miles transmission broke just a few months out of warranty. Also started experiencing excessive oil consumption and noisy engine. Have heard and read too many reports of people with the 5.3 liter having major mechanical problems I.e. camshaft lifters piston rings and valves all going bad.
