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.

Impala 3.4L

  • Automatic transmission
  • 127,500 miles

GM is aware of premature failure of catalytic converters for 3.4L motors. On another site it is reported that GM will offer some of the money for a catalytic converter ($595 for OEM part) for Impalas with less than 120k. Mine was 7.5k over.
