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.

Regular occurrences started at 120K miles, these are all issues which previously complaints have been filed by current 2004 Grand Am owners but have not been corrected and I have called every 6 months filing these complaints. 1) gas fumes are coming in the car when it is running or sitting still idling, 2) blinkers start blinking on their own around 80 degrees F outside temperature, mechanic said it was because grease in steering column becomes thin and shorts out other wiring causing the smoke (fire) which comes from steering column, this occurs every summer to fall when temps are 80 degrees or higher), 3) horn does not work, mechanic replaced horn mechanism but it did not fix the issue & I am concerned the air bag system won't work either since they are inter twined in the steering column, 4) the dash is warping, cracking and breaking horribly, it causes a sticky haze (gas) on my windshield causing issues when driving at night, I continually wipe off but it does not help, 5) the service engine soon light has been on for 2K miles, the mechanic states it is a fuel system indicator code, indicating the fuel cap is not fitting correctly, which he has confirmed is incorrect. Starting at 142K the car overheats (I just got the water pump and thermostat changed), the car shakes tremendously and shuts off while driving when temperature gauge is indicating this overheating, leaving the car unable to be driven since no power steering etc, the replacement of the parts has not corrected the issue. I am very tired and worried about my family's safety in this car. Please assist as I have been calling since 2013 about the #'d issues. Thank you.

Grand Am

  • 128,579 miles
My son was driving this 2004 Pontiac Grand Am and noticed gasoline odor/fumes coming into the vehicle cabin area with the HVAC system operating. Upon inspection of his complaint we noticed fuel leaking from the fuel pressure regulator. This fuel leak was minimal when the engine was at mid temperature but became worse when the engine reached operating temperature. During additional diagnostics we also noticed when the engine was started up cold that the fuel leak was easily identified and leaking profusely. We promptly shut the engine down contained the fuel leak and disconnected the battery until the fuel leak could be repaired. The fuel regulator appears to be the original oem installed component. We replaced the fuel regulator assembly and the leak has now been corrected. The faulty component appears to have a pinhole leak at the top hat area or some type of porosity. This is very difficult to see with the naked eye. If the regulator is pressured up to the correct specified psi I am certain that the leak will be absolutely identified. Current ambient temperatures have been in the range of 35-58 degrees Fahrenheit. This fuel leak came on suddenly and could possibly result in an under hood fire. I am convinced that if the ambient temperatures were in the summer time ranges this could have resulted in a potentially dangerous situation for the driver of the vehicle. I can send the failed part to NHTSA for analysis upon request. During further investigation of this complaint it seems that several other owners have had similar complaints with this fuel regulator leaking on this V-6 engine VIN code "E". I do request a follow up from NHTSA on this complaint and I will ship this component to NHTSA at my own expense upon request. The manufacturer has not been notified at this time and I will not contact the manufacturer unless instructed to do so by NHTSA.
