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.

Check Engine Light and 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.

Potential Fuel Leak at Fuel Tank

Some fuel tanks may not have consistent welds between the fuel tank and the fuel filler neck, affecting the strength of the joint. In the event of a severe rear impact, an improper weld can result in a crack in the joint. This could illuminate the Check Engine Light, cause a fuel odor, or allow fuel to leak out. Any fuel leak increases the risk of a fire. Dealers will replace the affected fuel tanks to correct this concern. This recall is scheduled to begin on August 15, 2011. The Ford recall number is 11S20.

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.

Mercury Montego Reviews

I have. 2005 mercury montego premier. I did scheduled services and treated her well. She gas 87000 miles on her. The gear shift is beginning to stick in park but i hear its just a computer upgrade. I love this car. Paint fades in the hot desert sun but have taken care of that too. She has never let me down and i plan on being happy with her for years to come
Bought Montego Premier new from dealer in 2006 with CVT and AWD. 141k miles and still running well. Great in snow and ice. Only maintenance has been brakes, tires & fluid changes, including extra special ATF (only available at dealer). Not too sporty, but for our family, this car has been extremely dependable transportation year round.
Best car ever owned. We owned this car used in 2010 with 55,000 miles on it. Only thing changed are brakes, battery, tires and put in new plugs. I love the styling of this car runs like new its at two hundred one miles without giving us problem runs and drives flawlessly. Seats are comfortable, car overall fantastic its in great condition all window regulators and cruise control still functions...
