It was raining and my vehicle kept going into neutral and stalling. I'd press the gas, nothing would happen. It wouldn't go into reverse. When I put it in neutral the engine just revved up. Putting it park was ok. Check engine codes P0715 and P0340 appeared. A flashing check engine light (!), and solid check engine light appeared. Putting in drive, it would only go into 3rd gear. 1st gear worked if I moved the prndl to 1. reverse didn't work at all. I could have easily been killed if this happened while driving anywhere but my neighborhood. This is different from the recent torque converter recall that is also scary and also results in loss of forward momentum. My problem is with the PCM. The dealer performed diagnostics and repairs according to Ford's tsb 06-14-10 which indicates this is a common problem on all 1999-2007 Ford vans. If they've known about this for 7 years, and it affects nearly a million vehicles, why hasn't it been recalled? surely NHTSA has received complaints about this. I have a friend who had this happen on her 2004 Ford van within the last year. She also lost reverse and the car would limp in drive just like mine did. The repair shop knew exactly what to do and repaired her PCM. I've asked her to file a NHTSA complaint as well. This is a safety concern. I paid my Ford dealer to fix because my safety is at stake, and obviously because the vehicle was performing sub-par, but I feel this particular issue should be covered by Ford, not by the customer, just as was done with the recent rear seat rust and torque converter recalls on this same vehicle. This is no different. It is beyond normal wear and tear.

Multiple times loss of power and ability to drive. RPM's jumped all over and vehicle would stall or not start at all. In and out of shop over 2 months leaving me without a vehicle or driving a loaner car. Finally replaced PCM and wiring harness. Not even a year later the exact same problem is occurring again and warranty is expired. Also found out another vehicle was in the shop at the same time with the same problem.

Stall engine with no power for forward or reverse. Malfunction indicator comes on and the vehicle will not start for more than couple seconds. Multiple ABS and drive codes based on the eec test. Repair shop inspects the vehicle and found water intrusion to the powertrain control module (PCM) and the connector pins where short out.

The contact owns a 2005 Mercury Monterey. The contact was driving approximately 25 mph when the vehicle suddenly accelerated, the contact depressed the brakes but the vehicle would not respond. After utilizing the parking brake, the vehicle stalled. The vehicle was towed to the dealer for diagnostics. The technician stated that water had entered the wiring of the computer system and caused the failure. The technician dried the wiring but the failure recurred. The vehicle was towed to the dealer again, where the technicians replaced the computer but the contact continued to experience the failure. There was also a failure with the rear passenger side sliding door, which would sporadically open with the vehicle parked and the key removed from the ignition. In addition, the fuel level gauge displayed an inaccurate amount of fuel and all of the instrument panel lights were illuminated. The vehicle was not repaired. The approximate failure mileage was 17,000. Updated 5/11/12 the consumer stated the computer also was wet and caused system failure in February 2010. It was replaced then. Last brakes twice. March 12, 2012 vehicle would not reverse and raced in neutral, torque converter failed. Handicap lift failed. Updated 06/14/2012

My 2005 Mercury van died without warning and after taking it in for repair, was informed it was the PCM module or computer that failed due to moisture. The cost of repairs is $962 and the module design is defective allowing moisture to cause the part to fail. The part is mounted in the front cowl and not protected nor sealed from weather. Research has shown that this is a widespread problem on this model and many horrific safety incidents have happened with the van's failure. Ford should be held accountable for this defect!

The computer system in the van has malfunctioned in the exact same way twice. It says the rear sliding door is open when it is, in fact, closed. It also beeps for 60 seconds every time you stop and start going again. This has already been taken in and repaired twice. It is more than a hassle for us to get the van in to be repaired due to having infants and working a very strict schedule in the military... which is why we bought a new vehicle.
