“I was driving down the interstate for about 50 miles and exited at an off ramp. At the end of the ramp, my 2005 Mercury Mariner stalled causing loss of control.. My Mariner would crank, but would stall once engaged into forward gear. I was able to keep the vehicle from stalling by idling at high rate in neutral only. My vehicle stalls once placed into gear and coming to a stop at periodic times. …”
NHTSA complaint #10361317, filed 2010-10, 95,455 miles“I purchased a 2005 Mercury Mariner on 2/14/13 from a local dealer in my area. Within two days the vehicle broke down on me. I did not purchase the warranty (stupid mistake) but I did take the vehicle back to the dealership in which they assured me they would fix the problem. It was a transmission problem fast forward to 03/2015 the transmission went out in the vehicle which cost me around $3,000. That is more than I owe on the vehicle, would not recommend this vehicle unless you want to pay for it twice.”
NHTSA complaint #10905973, filed 2016-09, 90,000 miles“I purchased a 2005 Mercury Mariner in march of 2007, this vehicle had 11,000 miles on it. In june of 2009, I begin hearing rattling noise in the engine and the gears begin operating very poorly. Had an auto shop check out what the problem could be in june of 2009, and was told my transmission needed repair. I stopped driving the vehicle and begin using a rental car until I could put the money together for the repair, which I was quoted over $2100.00. …”
NHTSA complaint #10416339, filed 2011-07, 40,989 miles“On the freeway and car suddenly has overdrive light blinking, at the same time I began losing power, I was able to get off freeway but not after I open hood and nearly got run over. I was checking to see if there was overheating or smoke. But nothing. I have already replaced PCM, transmission, and torque converter. Consequently my shifter is broken and you can see down into transmission. Obviously no I can't drive, I will have to have vehicle towed. Why hasn't transmission been recalled on this vehicle. I could not think about if my child would have been with me and stood in front of car. …”
NHTSA complaint #10984959, filed 2017-05, 160,000 miles“The car stopped running as I exited the interstate off ramp. This was in high traffic with cars behind me. I was able to get the car restarted and coasted to the side of the road. A tow truck took me to a ford dealer, where it was stated the torque converter had failed. The ford dealer told me that a new code number had been issued because there were so many problems for ford escape and Mercury Mariner from 2003-2008. My vehicle is a 2005 Mercury Mariner. I had no previous indications that this would fail and was traveling out of state. …”
