Thursday may 23 2019. Driving down the road and my van just cut off. I was able to restart the van and get into a parking lot. I sat for a bit and tried it again. It started. But I had no power to go forward or reverse the transmission was just gone. Absolutely no warning or anything like this had happened. No service engine light .. I was on a city street. I had just pulled forward from waiting for a red light.

Tamara recall. On 5/26/15 the man I bought my 04 mercury monterey van 4.2l had problems with it surging when stopping or barely moving. Found bad trans,had it rebuilt, found motor mount, trans range sensor bad also torque converter and over haul kit,3 shift sol and reverse boost valve. 6 months later I bought it.on dec7,2016 my van didn't seem right to me I could tell it had a skip and seemed slugeshed when it would shift. My check engine,and transaxle light came on as long as I keep it in 1,3or drive it don't come on or blink so I looked in the owners guide to see if I could find something. Seen where it has to do with the transmission, transaxle, and alot more. So I got on the fords website seen a list of recalls so I put my VIN# in and sure enough there I was.I have almost got hit when I was trying to get back home. If my van had completely went out and started do all of that when I was getting on or off the highway or interstate,on a train track it could of been bad it. It could of killed us.and it seems like what is going on now so I will say transaxle, power train, toque converter and over haul kit,3shift sol, and boost valve if I was a guessing all I know is I want my van again back running right again.

The vehicle stalled on me this morning as I was driving to work on a busy street. I attempted to crank it back up but the oil light as well as the battery light came on and the check engine light stayed on. I left the vehicle on the side of the road for 8 hrs, when I returned I was able to drive it for approx. 15 miles and it stalled again once I made it to my destination. Vehicle also backfires now and has a very strong gas smell coming from it. Started stalling after I drove through standing water puddles on the road.

In early 2012 both brake lights on dash would come on sporadically while driving.then came on more frequently. Soon the battery light started to come on at stops or low idles. 8/2012 dealer could not reproduce the brake lights coming on, but replaced alternator. 11/2012 still problem with brake lights on the dash coming on now plus the check engine light. Vehicle sputtering and stalling (could not stop without vehicle totally stalling and had to have foot on gas at all time, even when braking, or would stall.) 2nd dealer still could not verify the dash brake lights but resealed connector, replaced spark plugs, clean mass airflow, reset kam, replaced heated pcv hose. Could drive vehicle but brake lights were both still sporadically coming on while driving. 7/2013 still having problems with both dash brake lights coming on only now the radio dies when they come on, when they go off, the radio comes back on. If the radio didn't go off, sometimes shutting it off would result in the brake lights going off. Dealer still unable to verify. This progressed to the battery light coming on sporadically (around time brake lights would come on) and usually going off if the AC was turned up on high. The vehicle also started to lose power when passing, felt like a down shift. The dash light issue occurs daily, but there is no pattern. It can be wet, dry, hot, cold, after 5 miles, after 30 mile, side streets, expressway, morning, evening there is no constant. 10/2013 vehicle back at dealer since the problem happens every day. They can't reproduce. Only code they get is the alternator, which was replaced last year and didn't help the problem. They have resealed the cpu and that doesn't help.this vehicle has been plagued by electrical problems since day one (heater, seat heater, cigarette lighters, door locks etc) concerned electrical issues could result in loss of power or fire.

I purchased this van from a one owner elderly couple-at the time of purchase had 47,000 miles on it. Worked great for first 8 months then the problems started. Had to replace spark plugs then coil assembly, then fuel injectors, value exhaust gas, recall of the torque convertor(dealership had my van 3 days shy of 1 month) ABS sensor replaced, replaced callopsed pcv hose, water in the computer modele this had to be cleaned out. Van was in and out of the shop 8 of 12 months in the year 2012. I had the van back for not even 2 months and it started running rough and idling high again the engine light blinking. I really need some help with this-because the dealership I have been taken it too cannot seem to get it fixed!!! I have spent way to much money on a vechile that does not work!!!

1st - radio started flashing on and off randomly - took to ford dealer - no error code, no answer. 2nd - heated seat on drivers side quit working - took to ford dealer - no error code, no answer. Took to private repair shop - error code of low voltage battery - replaced battery for $125 3rd - automatic lights quit working, dashboard control went blank - took to ford dealer - same low voltage error code - despite new battery. No other answers. 4th - automatic seats started moving when using code to open door - took to ford - found that all problems traced to one relay box - replaced relay box for $650. 5th - engine light came on one week later - no problems starting/running, made appointment to take to dealer in 3 days. 6th - engine died next day, would restart and then die again after 5 feet, towed to ford dealer, tow truck driver noted engine would not go into gear- repeatedly gave no code. Asked them to have tech take car home and drive it. Finally found corroded and wet PCM. Quoted $1400 for the repair. I looked up PCM on merc. Monterey/ford freestar - as these are essentially the same vehicle. Found tons of same complaint. Poor design from ford allowing water to drip onto main computer/electrical supply causing thousands of dollars of repairs to owners. The battery was likely just fine, the relay box likely just fine. I am working with dealer to pay less for the PCM since they should have found this from the first or second electrical complaint. Car still at dealer, I will not pay $1400 to get it repaired.

On saturday july 2, 2011 we were driving our 2004 mercury monterey from the upper peninsula of michigan to our home in ohio. My wife, three children, and I thought we had a day of driving ahead of us and then the vacation would be over. Suddenly, without any warning, on the highway near gaylord michigan the engine continued to run but the car was not being pulled forward. All we could do was coast to the side of the road. Our van has only 67,000 miles on it and has never had any kind of transmission problem. There were no check engine or any other warning lights. We had the van towed to a repair shop, and they told us the transmission was bad and that this is a known problem with this ford mercury monterey. Since it was saturday july 2 we had to wait three days (since monday was july4th) to even get a quote on a rebuilt transmission. All the rental car companies were also closed until tuesday. We finally got the car back on friday july 8th with a rebuilt jasper brand transmission in it for a cost of $3,422 plus a hotel, tow, rental car, etc. Through research on the internet I have found that many other people have had this same problem with ford freestar and mercury monterey minivans.
