At 28000 miles the transmission started shifting erratic, the dealer reprogrammed the ECM and covered up the problem until the warrant ended and the battery failed at which time the car reverted back to default and continued to buck and jerk until the car reached highway speed. This continued until the transmission finally failed during operation on the highway on 3/5/20. The ABS module just failed during low speed operation for no apparent reason. Also the car indicated that there is an electrical problem even though all electrical components are in good operational condition. This error comes and goes constantly at any given time.

What owners say
While driving to work one morning all I here was ding ding ding od/off started flashing . Sec later check transmission light came on now when I drive putting foot on the paddle to go it will idle up I release and it will shift n go. Aamco saying that I need a rebuilt tranny that's bs with all what I have been reading it's just a rip off I don't have $3500 to get this fix. Now seeing not once not twice so many complaints I read that people paid for 2 or more tranny for the vehicle's and nothing is been done about it. And the ford deals knows about it..... Do a human being has to lose their life before ford dealer's can own up to there responsibility? If they was in our shoes they would want the same thing vice verse they say u reap what you sow. Please please please help up just fix our transmission that's all.. Another thing ABS light stays on check engine light stays on the seat belt light stays on all my windows doesn't let down now wtf?
I was driving my vehicle and a light came on that said check the charging system, the car's electrical system completely crashed and all the electrical power to the car died and it literally turned off while I was driving it in the middle of the street. Now even with a replaced battery and alternator it will only start with a jump and continues to say the charging system needs to be checked. This is extremely dangerous. What if I were driving on the highway and all of a sudden (with no reduction of speed) the vehicle just turned off and stopped. No electric meant no powersteering, no ABS, no air bag sensors etc... Very dangerous. I have checked several blogs and sites and I am finding a number of people are having the same charging system issue. I would like to return the company to cover the cost of repairs for this vehicle.
Changed front pads ( never opened bleeder)then had soft pedal, after that changed frond brake lines master cylinder, booster, ABS control unit and calipers still soft pedal. Then used snapon scan tool to perform brake bleeding in ABS control unit, still problem persisted, as of now still no luck (bleeding all 4wheels in factory specs have been perform/bench bleeding) still soft pedal.
My ABS brake light pops on and off constantly.
Have been having trouble with door locks, delay switch on rearview mirror, window lock and window functions, ABS on all the time ,door ajar light on all the time. Nonfunctioning dome light switches and intermittent check engine light ( which when checked was determined to be some unknown insufficient exhaust flow issue). Constant clicking noises coming from the far left drivers side of dash. We noticed a flame coming out of my left front top dash vent after car had been parked for 5+ hours. It's obvious the fire started in the dash and it burnt both of the wiring harnesses under the left front control panel hitting the vent line and coming out the top vent of the drivers side of the dash. We had to poor buckets of water inside dash vents/ openings and front hood area to get the flames out. Our injuries were incurred while trying to put out the fire.
2003 mercury mountaineer awd 4.0l. We purchased our mountaineer in june of 2004, with 22,000 miles on the odometer. Approximately 300 miles into our ownership, we experienced a front bearing wine. Dealership covered defect under 3 year / 36,000 mile warranty. Other defects covered...replacement of the rear speed sensor at 23,454 miles. A 2nd ABS problem required a new actuator speed control switch assembly at 28,419 miles. Transmission shift solenoid replaced at 32,075 miles. Driver side passenger window motor replaced at 33,443 miles. Recall on rear glass hatch lift struts at 27,379 miles. January 23, 2006 our mountaineer now has 42,777 miles on the odometer. We noticed a low pitch noise starting at 25-30 MPH and becoming higher in pitch at higher speeds. Our local lincoln / mercury dealership service advisor determined we had a faulty rear axle ring & pinion gear set. They rebuilt our rear axle using the VIN # to determine actual bill of sales date, which was june of 2003. This gave us a warranty until june of 2006 thus nearing the end of our 36 months warranty. We regretfully admit paying a $200.00 deductible the dealership asked for. We drove off with our newly rebuilt axle in our mountaineer. Our noisy axle never went away. The dealership blamed this due to worn and noisy tires. We replaced these tires at 47,500 miles or 4,500 miles after the original axle noise complaint with no real apparent change to our noisy problem. Our mercury mountaineer went back into the shop at 48,300 miles with a noise still distinctive from the rear. Again our local mercury dealership took a look at the SUV with the service manager riding in the vehicle. His comment... Sounds like an on-going rear axle issue. He would check with his district manager about replacing the entire axle assembly this time around. They contacted us by phone the next day. They didn't believe it was the axle, but one of the rear outer hub wheel bearing assemblies. It would cost us $270.00.
Abs light has came on 4 times in 2 years I had the ABS sensor replaced every time the truck has only 35450 miles on it. I paid over $31000 for this truck and I have had more trouble with it than any truck I have ever had in the past.
At 43577 miles I am having to replace my rear-end. This is going to cost approximately. 1500.00. Also ABS sensor has to be replaced.
Abs on brakes cut in when should not. Made it difficult to stop.
