Driving at 40 MPH car stalls, pull over, car starts up engine lite on, (sat) take to dealer on mon (12/15/2014), explain to dealer, they call 3 hours later to say "purge valve needs to be replaced"ok this should be covered right? She says no! The cost to you will be $320.33. I told her this is part of the emissions, it has to be, she said no its not! I purchased this car from this dealer 3 1/2 years ago, (bought is new) still underwarranty.. But this is not covered! The 800 number to fords blew me off! And said what the dealer says goes!>. Why did she suggest I call them then! (not good customer service) I was hoping for explanation! Please help, this should be covered. Look at your on line complaints about this! Shame shame shame. Of course I paid it, I need my car! Please note I was told that there were at 5 or more cars with the same/similar problem.

I was driving down the highway on my afternoon commute home with my 3 yr old daughter in the back seat and my vehicle lost power and the check engine light and a wrench light came on and it would not go above 25 MPH. I almost got hit in the rear of my vehicle cause I was not expecting this to happen by any means, but I was able to coast off the highway and shut the engine down for a few minutes and restarted it drove about 5 miles and it did it again.

She pulled into a patients driveway and stopped she went to put it in park and the car just took off into the house. She (the driver) had to be taken to the er. She had her foot on the brake still when the car took off. I have pictures of how the right front tire was dragged through the dirt while brake was applied. It damaged the home and did over 5000.00 damage to the car. She insists it accelerated unexpectedly.

Traveling on 2 lane road at 55 MPH. Engine set at cruise control speed when power was lost. Vehicle felt like it was coasting, the accelerator would not work. I was able to coast to a stop on a side street, then had my vehicle towed to the dealer for repairs. I checked web sites last night and found this to be a recurring problem with ford escapes and mariners. Cost of repair was $382.37 and not covered for any reimbursement by ford/lincoln. Cutting off like this is extremely dangerous and places occupants at risk for serious injury.

While driving down the highway, in my 2011 mariner it suddenly lost the power to accelerate (engine still running). The wrench light illuminated at this time. Pressing on the accelerator did nothing. Fortunately there was nothing behind me so I coasted about 1/4 mile to the next turn off and coasted off the highway. Then I turned the vehicle off, waited a few minutes and restarted it. I drove about 20 miles home with no other occurrence. The next day (august 14, 2013) I drove about 20 miles to work with no problems. That afternoon I left work and drove about 2 miles at 25 MPH and it lost all acceleration power again (motor still running). I turned it off and restarted it. I drove another 2 miles at 25 MPH and it lost acceleration power again, but this time both the wrench light and the check engine light came on (engine still running). I then drove directly to my ford/mercury dealer (about 1 mile) and told him the situation. It is currently in their shop and I haven't heard back from them yet. They gave me a loaner vehicle to drive while they check out my mariner. -- extremely scary situation! If this happens to me on an interstate in a center lane with heavy traffic will be life threatening. I don't want to be afraid driving my vehicle and think a recall should be done asap!! Today I have read other similar situations people have experienced with mariners and escapes. Please check into this asap before there is a tragedy if there hasn't already been one gone unreported!!! Thank you!!

As I was driving my 2011 mercury mariner it suddenly lost the power to accelerate (engine still running). The wrench light illuminates at this time. I could not do anything to increase speed (pressing on the accelerator did nothing). The only fix is to shut down the engine and re-start. The mileage is 69,xxx. This first occurrence happened on 7/25/2013, however, the same symptoms have occurred randomly several times since that time. I explained the symptoms to my local ford dealer service department and indications are a defective throttle body.
