I won a 2007 mercury milan with a 3.0l dohc motor. I was turning onto the road I live on, started to accelerate, and it started spitting and sputtering. It felt like it was running on only a few cylinders. We had the computer scanned, and replaced the two coils that it claimed were the issue. Drove it down the road, and it still did the same thing. We then took it to a local automotive electrician, who told us that one of the coils we didn't replace (which never showed up as bad) melted so badly, and shorted out the PCM. He replaced a few more coils, the PCM, had the computer flashed/reprogrammed. I've read all over the internet that this has happened several times with this same motor, and I'm wondering why ford/mercury have not bothered to issue a recall.
2007 Mercury Milan electrical complaints
Page 2 of 2: complaints 11 to 14 of 14, newest first, as owners wrote them.
Incident occurred as driver of mercury milan 2007 awd premier vehicle was driving on the highway at a speed of around 50-45mph. The car began to shudder and vibrate. Vehicle dash lights and engine cut out completely in the middle of driving, driver managed to make it safely to the side of the road. Car was towed to nearby auto service facility. Upon inspection the PCM module was found to be defective. The PCM module shorted out all 6 ignition coils and dumped fuel into the cone of one catalytic converter stopping it from working. Further investigation showed that the PCM module is a documented problem for a variety of makes and models of ford/mercury cars. The PCM module was also on backorder from multiple locations. The mechanic also made extensive inquiries about the current PCM module and the backordered PCM (with new drivers and programming). The mechanic was informed that placing the old PCM in the car would result in similar electrical components being compromised because of the faulty version of the PCM. Total bill resulted in $3600, gross safety hazard for the car shutting down on a busy highway. It is my hope that ford begins to evaluate this as an issue and push it to the recall list before someone gets seriously hurt. Lastly, the back ordered part meant the car was not available to drive for over a month.
Tl* the contact owns a 2007 mercury milan. The contact stated while driving 60 MPH the engine light illuminated and the vehicle began to sputter and then stalled. The vehicle was restarted and taken to a dealer for diagnosis. The dealer informed the contact that the distributor shorted out causing it to melt and spiked voltage to the power train control module destroying it. As a result, all the distributors and the power train control module needed to be replaced. The vehicle was repaired. Also, the dealer stated that the manufacturer had developed a kit to help resolve the failure in the power train control module. The failure and current mileage was 107,000.

The vehicle jerked while on a state highway repeatedly until I was able to pull over and then it failed. Found out that the ignition coils had completely burned up, which I was told by the dealer is very unusual. Once the ignition coils were replaced, they determined the PCM(computer) had to be replaced. Keep in mind that my vehicle had been in the repair shop 4 times before regarding my radio after they replaced the radio 4 times, they realized that it was also the PCM that caused this problem. Every problem that I have had has been electrical. Electrical problems are not easy to determine prior to it happening like if it were mechanical. I have fought with ford over and over and they will not take responsibility for the defects in this vehicle. No one should have to replace a radio four times and a PCM twice in four plus years. This is ridiculous!
