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.

Cobalt 4-cyl

  • 47,800 miles
Noticed a faint smell of gas while driving my Cobalt on Thursday September 15th, 2011. Gas smell grew stronger later in the day and, on Friday, was so strong that it was overpowering, even with the windows rolled down. Upon taking my car to the mechanic, they found that a plastic supply port on the modular reservoir of my fuel pump had cracked and it was creating a severe fuel leak. I had to replace the fuel pump in order to fix this situation, but, three days later, my car still has an existing gas smell to it. On Friday when the incident occurred, I felt like I had ingested gasoline all day, and it took a while for that feeling to go away. In addition, I know that gas leaks are potentially very hazardous and can start fires. In conducting research, it seems that this problem is consistent with recall id # 09V419000 dated 10/29/2009 in which 2006 and 2007 year Chevrolet Cobalts were recalled for the same problem in some states including Arizona, where my car was purchased and registered. Service members at a Chevrolet dealership have stated that this issue has become common with my year Cobalts, so perhaps the 2008 Cobalts should be recalled as well? this is a hazardous problem that has turned in to quite an expensive fix for me, and I believe that it needs to be taken care of immediately.
