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.

2004 Mercury Mountaineer Owner Comments

problem #1

May 242004

Mountaineer 8-cyl

  • Automatic transmission
  • 1,500 miles


Purchased a 2004 Mercury Mountaineer back in March. Noticed a chirping noise at about 1500 miles when the air conditioner cycled on and off. Dealer replaced compressor. Chirping came back at about 3500 miles, so I took it back and the dealer adjusted the clutch air gap. They said it was fine, but found that while driving the vehicle home it was still doing it. Dealer said it has no idea what the problem is and has so far not offered to do anything about the problem.
