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.

Son was driving car and hit another car head on. He received concussion and broken foot. He is not sure what happened to cause him to go left of center, air bags did not deploy and car was totaled. This was actually 2nd time car veered off for no reason. First time car hit a curb and blew a tire. No explanation as to why this happened, then car was drove until the serious head on crash, now that recalls are being made public about ignition issues, we feel like this caused both wrecks.

I was pulling into my drive way and my power steering went out. On a separate occasion my blower motor would not switch off I had to remove the battery cables in order for it to shut off. When I had it looked at the blower motor resistor had burn marks on it. And I was lucky to have it replaced as it could have caused a fire. The car over heats when the heating system is not working despite having a new water pump replaced. I was slow on my street and the key had fallen out of my ignition and the car shut off I was not going very fast and I was on my street but it was scary as I had to try to pull the car over in order to try and restart it. This vehicle says it has many recalls but when I place my VIN in the GM website it says nothing. My air bag light is on and I feel as though my car may not deploy the air bags in a crash.

Car was in the shop 9/16 - 9/17/13 for an ABS harness. Late afternoon on 9/17/13 I was told the car was ready. We left it there overnight because we couldn't get there before closing, so we picked it up at 7:00 am this morning, 9/18/13. My daughter drove it 10 miles to school and parked it. Within 30 minutes the engine was engulfed in flames and smoke. By around 9:30 am the car was towed away and its been deemed totaled.

Grand Prix

2004 Pontiac Grand Prix transmission slipping/jerking motion going from dead start or uphill/downhill. Seems very very dangerous as trying to pull out into traffic is never consistent and the jerking motion forces people behind to slam on brakes. Happens up to 3 times in a row. This is a very dangerous issue and something needs to be done about this I do not want to be driving in danger like this anymore.
