2008 Mercury Mariner 4dr SUV

200-horsepower 3.0L V6 4-speed automatic AWD

15000 mi Gas mileage dropped significantly over the winter months. Had been averaging 20/21 mpg consistantly, then 17/18 over the winter. When originally informally, discussed with the dealer service, we were told that it most likely was the winter gas... 
7000 mi Engine oil leaking in small amount. Dealer put into the oil a marking substance which will allow them to track the leak with a black light at next visit.  
8000 mi Oil pan leak. 
10000 mi Engine pings at times. Unable to replicate with mechanic present. 
11000 mi Ford tech hears the ping - it is quite audible at times, very annoying too. The tech checked with Ford....no resolution available. Ping is intermittment, Ford 2nd level scratches its collective head. 
13000 mi Car sold with ping still present.

39000 mi Some sort of software glitch that threw off a "park immediately, hazardous condition" fault that when we restarted did not appear. We took it to the dealer, they found the fault code was there but couldn't find the source. Reflashed SW & we're done 
102000 mi

US $680
The faulty item was the high voltage battery coolant pump, which cost approximately $240 material and $200 to replace. At the dealer's recommendation, we also replace the coolant to ensure there wasn't debris in the system. 
149000 mi

US $898
The ignition switch was starting to malfunction, taking two or three turns of the key to get the contacts to close and the car to start. This was not going to improve, so we had the switch replaced. At least we didn't have to get new keys
