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.

Aztek 6-cyl

  • Automatic transmission
  • 41,000 miles


Loud knocking noise in engine. We had it in the shop twice so they could remove and disassemble the engine and replace all six pistons, rod bearings and gaskets. First time at 34,000 miles, second time at 46,000 miles. Currently at 51,000 miles and engine noise is back. Front left wheel bearing went out at 41,000 miles. Left front wheel bearing went out at 51,000 miles. Fly wheel rattles. Rear hatch only works intermittently after 2 repairs.
