“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.”
NHTSA complaint #10606077, filed 2014-06, 60,000 miles“I was on onramp, vehicle slowed down, wrench light lit up on dashboard. Vehicle would not accelerate. I pulled to the side of the highway and restarted vehicle. Vehicle continued to do this for the duration of our trip.”
NHTSA complaint #10525503, filed 2013-07, 40,876 miles“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. …”
NHTSA complaint #10535515, filed 2013-08, 45,500 miles“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.”
NHTSA complaint #10543368, filed 2013-09, 49,000 miles“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! …”
