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.

Heater Core Leak Notes: The Pontiac Vibe is the mechanical twin of the Toyota Matrix.

Both models were a joint GM-Toyota venture, manufactured together at a NUMMI production facility in Fremont, CA. Only the heating & A/C systems are different.

2006 Pontiac Vibe Owner Comments

problem #1

Dec 152009

Vibe 4 cyl

  • Automatic transmission
  • 27,847 miles


Bought a 2006 Pontiac Vibe, knowing it was a TOYOTA. No issues, then 3 months out of warrantee with only 27K miles, the heater core starts leaking!!!!

To top it off I find out the heater core was made by Delphi. If figures that it was the GM made part that went bad.
