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

Nov 262012

Mountaineer Premier 4.0L V6

  • Automatic transmission
  • 92,000 miles


After a couple months of transmission/transfer clunking when shifting from drive to reverse, my 04 mountaineer just stopped moving at an intersection and went into ENGINE PROTECTION MODE. Turned out that the center shaft that went through the transfer had the splines stripped out. Luckily only the thing that needed replaced was the center shaft. But it still required a rebuild + parts and labor. If it was the shaft on the Transmission side it would have been alot more expensive. Overall very happy with my Mountaineer. Very capable and full of options. only problem I ever had with it.
