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.

Strong sulphur odor from exaust, seems worse in the warmer months. Dealer initially said it was the type of gas, but now claims all Vibes have the odor and that it is normal for this car! I called customer care at Pontiac who called the dealer, and then agreed with the dealer.

Pontiac Vibe 2003 presents "rotten egg" smell. This is hydrogen sulfide gas, which can be harmful, even deadly. Smell gets inside the driver's cabin via A/C.

The consumer indicated that the catalytic converter produced hydrogen sulfur that caused a rotten egg smell. The odor then entered the cabin of the vehicle through the air vents and made the occupants sick. The manufacturer denied there was a problem.

During sporadic times, the inside of the car will start smelling like rotten eggs. There is no correlation to how long we have been in the car or a certain speed. The smell will come and go. Sometimes the smell is noticeable from the outside of the car once we have stopped at our destination. Dealer says that this is normal for this car.
