2010 Mercury Mariner electrical problems

Filed Sep 8, 2025 · Electrical, Engine · NC

Me and my wife purchased a vehicle from a private seller to use for personal commute. A month later we started to notice more issue were occurring with the car then stated from the seller. I took it to an auto body shop to get it inspected and possibly serviced and upon that inspection the clerk stated that there was a milage adjustment done to the vehicle. We contacted the seller to try and return the vehicle and receive our money back, but the dealer refused and requested us to resell it.

When the weather is hot (close to 100 degrees or more) and I am driving with the a/c - my vehicle on 3 occasions will not start after parking the vehicle and trying to restart it. The red padlock sign blinks and it won't start. At first it is trying to turnover but then will continually sound worse and all other warning lights go haywire. I leave the car alone for half a day and it starts up again like nothing happened. On the fourth occasion, the car stopped while driving, just a quiet shutdown and the car glided. This time it did not work for over 24 hours and then started up again like nothing happened. Multiple mechanics and also the dealership cannot figure out the problem because by the time i have it towed to shop, it works again. They did a full check on the car and cannot find anything wrong and there were no diagnostic codes. This issue happens when the weather is hot and poses a safety concern as now it is shutting off while driving and I become stranded each time. (First incident happened 8/25/18, last incident 5/14/22) Total of 4.

Vehicle's electronic power steering turned off in the middle of driving, turning on highway, this has happened 3 times, seems like when the heat is on. Recall 14s05c shows up in service records from this car. Works was done my mahopac ford, mahopac, ny. Reflash ic and pscm. This recall was apparently addressed, but the problem has come back. I just bought this car used two weeks ago. It did not have this problem until I turned the heat on. Not sure what to do.

Power steering suddenly stopped working while I was driving. The vehicle is extremely difficult to navigate but I was able to pull off the road to a safe area. After shutting the car off for 15 minutes and restarting the lack of power steering remained, but there was now a message saying "power steering assist fault". This car has several other electrical problems with regard to the A/C & blower, and also the drivers side window and dome lights work sporadically.

Switch for AC wont blow out air. Took it to valoline to add freon.. They said, it was full.. Cold worked for 5 days then AC stopped working at hotest time of month... Took vehicle back and they stated, it was full still but added more freon to make me happy.. After a few days no AC and I took to a mechanics business. The owner and 4 others stated that the belt is turning maybe they overfilled it.. Told me to take it back to valoline and have them take out all freon then put amount back in but not to full.
