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.

2005 Pontiac Aztek Owner Comments

Aztek 6-cyl

  • 36,130 miles


I would like to enter a complaint about a defective engine, 3.4 liter V-6, on a 2005 Pontiac Aztek. This car has a blown head gasket with 36,130 miles on it. I am being quoted $1100 for repairs, and there is no way a car with this type of mileage should be needing this type of repair. This vehicle is/was in mint condition, and after conducting internet searches, it appears GM has a chronic problem with this engine and head gaskets.
