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.

Mountaineer 6-cyl

  • 64,500 miles
I am the owner of a 2007 Mercury Mountaineer. It has about 64,000 miles on it, most of them highway miles. I have a leak in my radiator. The dealer says it is a defect in the radiator, and no corrosion is present. It is out of warranty, so I must bear the cost of replacement of the radiator. Cost ~$700. I do not drive off road, so there is no valid reason the radiator should have failed. During an internet search, I discovered this is a common problem with 2006 and 2007 Mercury Mountaineer and Ford Explorer. This issue should be investigated, and Ford held accountable for putting defective parts in their vehicles.

I have a 2007 Mercury Mountaineer with 42,000 miles on it and was notified by my dealership that there is a leak in the radiator and it needs to be replaced. My dealership told me this was common problem with Mountaineer but Ford will not stand behind the equipment.
