2007 Mercury Montego Owner Comments

problem #5

  • 66,500 miles


An electronic device known as the smart junction box has failed 3 times since new.the first two times it was replaced under the original manufacturer"S warranty. The warranty has expired and it failed again. This part is very expensive costing in excess of $500 plus labor charges which I must pay. When this part fails, the signal lights, brake stop lights and other devices do not work which are essential for safe operation. Vehicle reliability and security are in serious concern.

Traveling at freeway speed, vehicle lights all flickered the lost power..engine continued to run, was able to coast vehicle to shoulder of 35W, apply brakes and stop. Turned off vehicle and restarted within a few minutes. No lights no dash lights..flooring the gas pedal able to get 30 mph uphill approximately. At top of hill power came back on..then killed again. Tow called. Currently at garage where sensors are showing transmission problem.

This is the 3rd headlamp assembly that's been replaced on the car, the bulb keeps melting. I've contacted Ford & they say that there's no problem or complaints.

We have had intermittent electrical issues for several years.the car suddenly looses all electrical power. The battery is completely depleted. Once jump started the car will then operate properly. I have had the alternator replaced once and the car has been checked by mechanics several times, no one can find the problem. We often times smell a burnt plastic odor just before the failures. This failure has happened dozens of time over the past 4 years, even during warranty. Ford did nothing for us.
