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.

Written by my wife on 11/04/16: On 11/02/16 at approximately 2:45 pm I was driving slowly through a parking lot trying to find a space. I found a space and as I turned my wheel to the left it locked up roughly, jerking the steering wheel out of my hands as I pulled into the spot. After the steering wheel locked up, jerking very abruptly, the power surged and the truck died. This is probably the 30th time this has happened to me. This particular time there was no error message displayed this time. Usually I get a message which pops up on the instrument cluster forward of the steering wheel that says 'service stabiltrac┐ or ┐action required, steering assist is reduced, drive with care.┐ it seems there is a steering malfunction because this issue usually occurs while making a turn but the truck has had this same error message while driving straight on the highway. I am unsure of what the problem is but I do know it is dangerous to drive this vehicle until the problem is resolved. Road conditions/weather conditions also play no part in when this malfunction takes place. Other pertinent information regarding this issue is that the headlights do flicker from time to time. We have been dealing with this issue since August of this year and have still not found a resolution. Landmark Chevrolet in taylorville, il has had our vehicle in the shop 4 times on this issue alone and put over 200 miles on our vehicle with no resolution. Friendly Chevrolet in springfield il had our truck for nearly 3 weeks and put over 70 miles on the vehicle...no resolution. Here are a couple videos we recorded and uploaded to youtube documenting the issue.

Clock and outside air temp readings are so small, you can't see them, without taking your eyes off the road, long enough to bend over close to the radio. This is as bad as someone using a cell phone to send and receive text. I have driven off the road twice, but have not crashed yet. My GM dealer says, the readings can not be made larger, and to be very careful.

The headlights on this truck are unsafe, they do not project enough light ahead for safe driving at night. One has to depend on the street lighting or stars. I have come close to hits others on the roads for the lack of projection of these lights. The truck becomes a hazard on the highway do to the slow speed one has to travel to stay within the headlights. Please address this with GMC before someone is hurt or killed.
