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.

After the purchase of my Grand Prix from mac haik in temple Texas the transmission started to have some problems. The car was returned to mac haik where the transmission was repaired or replaced. After only 3 years and having only less than $1,000 left to pay the transmission is going out again! no accident occurred I just have had alot of problems with the vehicle and am frustrated with the transmission problem for the 2nd time.

Transmission slipped into reverse from drive while going 40-50 mph on the highway. It did this on its own. Lost power and barely made it to the side of the road. After stopping I was able to shut the car off and then restart it. The car took off in drive and has been fine so far. I was just lucky that the was enough movement from the car mass to get it to the side of the road.

Dealership found passenger side front wheel bearing failure. Driver side front wheel bearing at mechanical wear limit. Both were replaced, as well as transmission main seals from age/wear/leakage and front passenger side lower ball joint. One month prior to this repair, the vehicle transmission shut down without warning and no electrical warning or lights while being driven. Because related other parts were repaired previosly and reported defective via this system on ODI id 10107847 and 10148428 and during this repair reported repair to Pontiac, the other associated parts were in specification. One lower passenger side ball joint was at the mechanical limit due to bad local roads on the passenger side edge of road/potholes and public utility access patches. Worn hubs (for the second time here, listen up) are available for inspection if needed. Both times this occurred, we noticed the failures either audibly (humming) or during state inspection, or both, and in all cases, the repair conditions were set by the dealership during the inspection phase. At no time during the inspection were apoligies offered, or better parts engineered, to prevent this from re-occurring. Just told that this was a common problem on this vehicle, good thing we caught it before we caused an accident (we?) and we cannot offer a better part to fix this problem permanently. They should be held accountable for the materials used to produce and investigate manufactured items for compliance with material(s) engineering and specification, as well as wear testing data that may have been improperly reported to present a favorable outcome of test failure anaylsis.
