2005 Mercury Mariner Electrical system Problems

“The car is parked in my office parking lot. The car alarm goes off. I can see out the window there is no one around the car. I use the remote to turn it off. Happens intermittently, a few times a day. I even took the keys out of my pocket and just have them sitting on my desk...it still happens....update 9/15/15 updated 12/13/2017”

“My 2005 Mercury Mariner premier has a problem when driving that the left and right door shows they are ajar. And it cycles back and forth across the dash board, you hear a beep then the message is displayed on the dashboard . When the car is parked and locked the alarm goes off between five and 10 times a night draining the battery. This has started about a year and half ago. I took my car into a ford dealership on september 27,20016 to be repaired. …”

“On august,2013 I went got my vehicle smoged . It passes good. Then the next day I see engine light air bag light. Then goes off when I stop.

My back wind shield wiper no longer works and my door ajar light stays on..I like my truck but I don't know how to fix this problem. I work 21 miles from my home and I work night shift. This is dangerous on the highway. …”

“Car accelerated as I tried to stop. Then when I tried to go, I pressed the gas and it would not go but the RPM's went really high. Then the car died and I had to wait a few minutes to turn it back on. 2nd incident- I was driving on a busy road during rush hour and tried to stop at a stop light but the car accelerated so I had to keep breaking but the car would not stop accelerating so I turned the car off. When I tried to turn the car back on, nothing worked (had no power at all therefore I could not turn on my hazards to signal to people that my car was stalled). …”
