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.

After several trips to dealership, where they swapped the harnesses out I found the bulb is loose in the socket. I can move the bulb around in the socket and it will work for a while.

Having repeated issues with the left front turn signal here too. Purchased the vehicle used in June 2006 with 49000 miles, and the signal went out the very next day. The bulb has been replaced approximately 8 times since. In 2008, the car was brought to a Pontiac dealership to determine if there was an electrical issue or something wrong with the housing itself, but they found nothing wrong. If anyone has any ideas on how to prevent this from happening, I'm open to suggestions.

So I bought my car for about a month the turn signals worked JUST FINE. Then all of a sudden the left front turn signal went out so i replaced the bulb well it went back out a few days later then came on then went out then came on. Ive replace bulbs ive looked at wiring NOTHING works. When a mechanic friend of mine looked at the issue he said it looked like the socket was corroding the bulb and making it short out. But still cant get it fixed its annoying and it has gotten me tickets for faulty equipment

We replaced the light ,wasn't the problem.Finally thought the inside needed to be adjusted ,it worked for a while.The light would go on/off,on/off,on/off,on/off,on/off cant list how many times that happened.Well lets order the parts we need to replace the entire socket that holds the light.Guess what that doesn't work either,SO what NOW ! I just deal with people cursing me ,giving the finger,pulling out in front of me when Im turning,Well What Do You Suggest OR Would The Company the LIKE to FIX IT,That Would BE REALLY NICE.
