2005 Mercury Monterey Electrical system Problems

“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. …”

“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.”

“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.”

“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 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.”
