2005 Mercury Montego Problems

Harsh 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.

Wrench Light, Service Engine Soon Light, Possible Poor Throttle Response

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.

Rear Brakes Wear Out Abnormally Fast

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 Recalls

Door 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.

Fuel Tank Straps May Break

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.

2005 Mercury Montego Reviews

I own a 2005 Mercury Montego with 63,000 miles. Twice I took it to the dealer where I purchased it, and who has done all the oil changes, etc plus any repairs, telling them there was something wrong with the transmission, possibly slipping, and something wrong with the brakes making a jerking feeling when stopping. They could find nothing either time. About 2 weeks later they had to send a t...
I like the size of the interior, however, CVT transmission always seemed strange sound and power wise. Was always told that that's just how the CVT sounds. Now transmission out at 65,000 miles, 4 years old, and FORD dealer offers little to no help since it has yet to be recalled, this at a cost of $5,,700.!! Also rear brake problems since day one, head light went out and had to pay $200 to...
My Montego is also getting a new transmission, after just 67,000 miles! What a hassle. Beware the CVT transmission....had I fully understood the "experimental" nature of the CVT, I would not have purchased this vehicle.
