The car has been lurching forward and decelerating randomly. Keeps going into "failsafe engine mode" and the wrench light comes on but only for a few moments, then runs normally again after restarting. Haven't been able to have the light on long enough to get diagnostics done. Happens while driving or when starting occasionally.

About 6 months ago all the dash indicators turned on. They went out for a few minutes then came back on and stayed on. I was told it was in the electrical harness. It would be a $700.00 plus cost to fix it. It is a common problem I would think there would be a recall on such a situation. I have to drive not knowing if there is trouble with the lights on full time.

Car runs great for about 20 minutes then I get a surge in the engine, dash cluster goes dead, car jerks and I lose power randomly. Everything comes back on but will go out multiple times getting worse everytime. I have lost power to transmission once, no forward or reverse. Replaced the dash cluster and car ran great for 2 days then started all again. This happens mainly while in the city, hasn't happened on highway yet thank goodness. Car just sits in driveway, afraid to drive it. I see countless people with this issue all the way back to when car was released and still no solution.

Dash board gauges and controls. When driving our 2005 montego all of the dash instruments and gauges will go out, and you loose some power, the rear lights go on. This can happen at any moment when the vehicle is in motion, on the interstate, slow speeds. To replace is quite expensive, but in doing some research I have come across thousands of complaints on the same issue, and it's extremely scary and concerning that a safety recall has not been done. You can turn it off but doesn't always reset and when it does the engine light stays on. This occurs while the car is in motion.

Started 2005 montego to pick up fianc from work, got back inside after brushing snow off the car and I pressed the throttle to drop the idle speed, all of the gauges on my instrument panel went black (tach,speed,fuel,water temp,AC/heater), my reverse lights came on, my stereo had really loud static coming through it and my wipers/heater stopped working. Came back a few hours later and gauges worked but check engine, transmission and charging systems lights were on. I put it in gear because I thought the issue was gone and as soon as I got to about 1500 RPM my gauges went black so I stopped and when the idle speed dropped back down my gauges came back on. I tried my headlights and they go out every time my gauges go out, which is any time I get over 1500 RPM.

Parked car at home after dropping daughter off in town car performed normally. Five hours later went out to pick daughter up. Started car and had no speedometer, odometer, tachometer, no cluster panel at all. No lights on panel, A/C would not function and backup lights came on and stayed on. The wrench symbol light came on at this time. I tested the car daily with the same results, until tuesday, august 11th. I had an appt to take it in to a ford dealer to have it diagnosed. When I started the car at this time, the cluster panel and A/C were working, the backup lights were off (except when in reverse) and the wrench light was now off. However, now the check engine light was on. Diagnosis at the dealership was that the cluster panel was bad and was sending incorrect codes (p0462 & p2067) causing the check engine light to come on. Since those codes are associated with the powertrain control module it could cause the engine to stall at any time.

Too many times to count 25 30 even more. When driving my 2005 mercury montego the complete dash cluster lost all functions and read outs, always at speeds above 30mph. A few times 9 or so the car would buck a few times. I had the harness connector checked and no problems found. This condition prevents me from using the vehicle as needed, to driver a few times a year from connecticut to north carolina and back to visit ailing family members. No other reasonable transportation available. We will pro ally never buy a ford product again due to safety concerns. Need advice as to problem and how to fix.
