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.

Cougar 6-cyl

  • Automatic transmission
  • 75,000 miles
The contact owns a 2001 Mercury Cougar. While driving 55 mph, the engine began making a knocking sound and eventually failed. No warning lights illuminated and the temperature gauge did not indicate anything abnormal. The vehicle began smoking once the contact pulled over and she noticed radiator fluid leaking. After restarting the vehicle, all of the instrument panel warning lights illuminated. The contact took the vehicle to a mechanic and they stated that a new engine was needed. She took the vehicle to midas for a second opinion and was informed again that her vehicle needed a new engine. The current and failure mileages were 75,000. Updated 02/01/08. The head gaskets were leaking which allowed radiator fluid to mix with the oil.
