1 Equipment problem

Failure Date: 09/04/2025

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.

My vehicle keeps throwing codes for the evap system. I have noticed many of these vehicles have to have their purge valve cannister replaced along with the selenoid for it. I have to replace mine. Is that not a defect if the vehicle? I have owned several vehicles and never had this issue with any of them.

8 Equipment problem

Failure Date: 10/27/2016

As I was driving 55 mph on a us route (no overpasses in the area), I heard what sounded like a gun shot and then the glass of my sunroof shattering. The interior shade was closed so I could not see the damage immediately. When I pulled off the road there was a large hole in the center of the sunroof glass and the glass was raised upwards as though it had been impacted from an object thrown from inside the vehicle. There was no evidence of any object that might have impacted it from the outside.

11 Equipment problem

Failure Date: 02/23/2015

1. Outside review mirrors do not defrost. They were frozen and I was on the highway putting my life in danger because I could not see outside vehicles passing to be able to go right or left. Then a week later their was frost on the mirrors and still they would not defrost again I couldn't see other vehicles on either side of my vehicle. 2. There is a gear shifting problem as well. Whenever I take off at a stop my car kicks real hard and loud enough to scare me. I have reported this several times with the dealer that I bought my vehicle from and they cannot find the problem. They have heard it do this but cannot seem to find the problem.

12 Equipment problem

Failure Date: 02/22/2015

My wife went to shut the back lift gate and window exploded in to small pieces.

13 Equipment problem

Failure Date: 05/03/2014

I had two separate occasions of my car stalling in the past three days. On may 1st I was traveling at about 40 mph when my wrench light came on and the car stalled out. Fortunately there was a median right by me and I was able to hurry up and move over before the car came to a complete stop. On may 3rd I was traveling at about 35 mph when the wrench light came on and my car stalled out in middle of the road. This time I was stuck in middle of the road but no one was behind me. I was able to restart the car and continue driving. If this had happened on the main road then there would have been a good chance of an accident occurring and harming me or my children.

14 Equipment problem

Failure Date: 03/08/2014

I was trying to accelerate at a stop light and the transmission (?) did not engage. When I came to a stop light the car jerked like it was it could not switch gears.

15 Equipment problem

Throttle opens and closes inadvertantly.

16 Equipment problem

17 Equipment problem

Failure Date: 07/29/2013

I purchased my 2010 Mariner 03/26/2013 from a local dealership. While driving at around 35 - 40 mph I noticed a grinding sound and difficulty to increase speed. I then noticed that my left blinker was flashing at a faster speed and the tail light went out. That was replaced. The car then would sporadically go dead and would have to be jumped. I had 3 different service shops look at the vehicle and found no issues. I did replace the battery and it appeared to run fine for about 3 - 4 days. It is now sporadically dead and the local dealership will look into the issue on 8/7/2013. Undetermined problem at this time.

18 Equipment problem

Failure Date: 07/29/2013

I had just gotten back from a long trip, and was stopped at a red light - I barely accelerated once it turned green, and the car lost complete and total power, in the middle of the intersection. A wrench light came on. No throttle was working as much as I pressed down. The car kept snail pacing until I got to an empty parking lot where I turned the vehicle off. I turned it back on and it reved itself, so I turned it back off. Turned it back on and all of a sudden it worked again. I took it to the dealer who claimed it was the "electronic throttle body" failing and charged me $98 for the diagnostic. I decided for a second opinion, and they took everything apart to see if it was something else since the car is only 3 years old and only has 30,000 miles on it. After much testing they concluded it was in fact the "electronic throttle body," and the repair cost me $595. Before this happened, 2 or 3 days prior, I felt the car was losing power and it was hard to get it to go at it's v6 potential. Car still hesitates and feels like the engine jumps out when it stops and moves again. . . Sure enough my engine mounts now need replacing, and that's anywhere between $350-$500. Another recall perhaps? it's been doing this since day 1, and my warranty ended about 6 months ago. Go figure. . . Just when 3 years was up! sigh.

19 Equipment problem

Failure Date: 07/06/2013

While driving on local interstae (271s) my car began to lose speed and dropped from 60 mph to 10mph then to a crawl. Luckiy I made it to the shoulder ( I was in the right lane with limited traffic) the car began to sputter and jump. I turned off the ignition. This could have been a serious possible fatal accident if I had been in heavy traffic. No warning was provided. It happened, the wrench symbol popped up as it was happening and there was nothing I could do. I travel daily on the highway to/from work. The traffic is very heavy. Luckily, I was on the road on th weekend during a fairly low populated time frame. I called Mercury and and received no assistance . I called my local dealership and received no satisfaction there also. This is a serious incident and has hapened to many ( I can provide website with testimonials. ) since this not a powertrain issue and it was past the 3/35,000 coverage, I stuck with the expense $360. 00. Wear and tear is one thing but to see a flaw like this occur for many and nothing is done is not acceptable.

20 Equipment problem

Failure Date: 06/24/2013

I was driving my Mariner and turn into a heavy traffic road and my car just went dead once I was in traffic. L was lucky that I wasn't hit from behind me. The car warnings displayed a wrench on the car panel. I took the car to the shop and it required repairs to the throttle control/power train. The car only has about 4600 miles on it. I have researched this problem on the internet and this is a reoccurring problems. There was no warning of a problem. The car just died in the middle of traffic. This is very dangerous and seem to be a known problem. Does someone have to die before they get this problem is recalled? the problem occurred so quickly that if you are not observant to your panel, you will miss it. And, it you are in an accident when it occurs, you will never see it.

21 Equipment problem

Failure Date: 06/14/2013

While driving through road construction on the interstate my Mariner lost power. I had my child in the backseat and was lucky enough to be able to pull over and turn off the engine. The power train light and engine light came on. I started it back up and continued until I could exit off the interstate and continue on the highway, where it happened again. Again, I turned off the engine and got it started back up. This happened one more time before I got it to the mechanic. He said that it was the throttle body and that it was on a national back order. There are 8,000 requests for this part! what will it take for Ford to finally issue a recall on an obviously defective part, a fatality?.
