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.

First the driver's side window stopped working, then the tail lights just went out on the 99 Pontiac Montana. They were just working and then on my way home they just stopped working. I replaced all bulbs and they still aren't working. Went to see a technician and he says it is an electrical problem. After that the radio display flickers in and out when the brake is pushed on. I've searched to see if I could find an answer as to why this happened and there are many websites with the same complaints as I have stated here with the same problems.

Dealer sold me a Pontiac Montana minivan and I only had it for 2 weeks, and it won't start, it had a carfax report that said it was in a car accident, this was not told or revealed to me by the dealer. Now I am stranded without a car to get around and no warranty was given. I ask for a warranty the salesman said it only comes with financing.

I had three transmissions, a cracked head because of over heating, water pump and heat sensor, oil in one cylinder, a short in the rear lights with dealer saying I (should replace the lighting structure on both sides) $200. ABS system sensor front right side wire burned through $500. The $200 and $500 I have not done yet, should I wait until it's an even $1000 more to spend more money? there are more problems.

The air bag light came on shortly after purchase while having other electrical system problems. It has been addressed more than 3 times by the dealer, whom I will no longer take my vehicle to for work. The air bag light is still malfunctioning, along with other electrical system failures presently occuring. The air bag light causes me great concern regarding possible unwarranted deployment leading to injury or accident.
