2005 Mercury Montego ProblemsHarsh or Delayed Shifting of Automatic Transmission
The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.
A defective electronic throttle body (ETB) can cause the Check Engine Light to illuminate and could have limited to no throttle response. Our technicians tall us that replacing the electronic throttle body will commonly correct this concern.
If the rear brakes wear out abnormally fast, this can be caused by defective rear brake pads. The rear wheels may also appear to become excessively dusty. They should be replaced with revised brake pads, and all wheel drive (AWD) vehicles should replace front brake pads as well.

2005 Mercury Montego RecallsDoor Latch May Freeze in States with Cold Weather
The side door latches may freeze in cold weather due to water intrusion. As a result, the door may not latch when closed, and could open while the vehicle is moving. Dealers will install a shield over the front door latches and seal a drain hole in the rear window molding on the Freestyle rear side doors. Grease will also be applied to all the latch mechanisms free of charge. The recall began November 8, 2006. The Ford recall number is 06S45.
The straps securing the fuel tank to the vehicle may break, allowing the fuel tank and heat shield to drop onto either the driveshaft or exhaust, depending on the model. If this happens, drivers may hear a noise or notice a fuel leak. A fuel leak in the presence of an ignition source may result in a fire. Dealers will replace both fuel tank straps. The recall began December 1, 2005. The Ford recall number is 05S37.
