Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My 18 year old son was driving my 2007 Mercury Mariner, when it started making loud noises and shaking like crazy, he was barely able to keep the vehicle running to get home. When my husband looked at vehicle and saw what it was doing, he thinks the transmission has gone out on it. We had driven the vehicle to church sunday morning (same day) and there was no signs or symptoms of any kind of problem. …”

NHTSA complaint #10579500, filed 2014-04, 87,765 miles

“I have just found out I have lost 2nd gear and 4th gear is on its way out on my car. Apparently this is a problem that ford has known about at least since 2012, according to an online ford motor company publication, maybe even earlier. The publication states that it affects 2007-2008 ford escapes and Mercury mariners. What I want to know is, if they knew about it at least five years ago, why wasn't there a recall and if not a recall, some kind of financial assistance/compensation for the repairs? …”

NHTSA complaint #10956248, filed 2017-02, 124,746 miles

“The vehicle had been driving perfectly normal all day. In the evening, while driving in a heavily-trafficked area, unexpectedly our Mariner would not shift out of 1st gear - the engine revved, but the car would just barely move. It finally shifted into 3rd gear, but never would go into 4th. All the while, the o/d light on the instrument panel was going on and off. This pattern continued for several days while we had our Mariner inspected at numerous repair shops; the end result was that we had to have the transmission rebuilt at a cost of $1700. At only 111,000 miles! …”

NHTSA complaint #10650583, filed 2014-10, 111,225 miles

“I was driving to work and car began to make a loud rattle noise, od light flashed (od off) and pulled over. I attempted to pull back on road and car would not shift into 2nd gear. Transmission problem. 1800.00 repair. Now 2013 exactly 3 years later and car begins same thing all over again. Diagnostic test states needs new transmission. Told these cars have had these problems from the get go. Ford knows this! The problem is coolant is located in radiator and does not keep trans from overheating. I am now told it will be 3650.00 for another trans. This is a total mess. …”

NHTSA complaint #10511020, filed 2013-05, 57,000 miles

“I purchased the vehicle with 6,000 miles on it. I kept up my normal maintance on the vehicle and replaced things when needed. At approximately 42,000 my transmission would no longer shift the gears. The vehicle was brought to wallace dealership of which they kept my vehicle for almost 2 weeks. They explained they did an overhaul of the transmission and fixed repairs on it so that their would be no further problems with transmission later on down the road. Now at 84,735 miles later, I am once again having transmission problems and my vehicle will not go into gear. …”
