Wrench light on mercury mariner 2011 with slow (20-40mph max) and rough ride home. Yesterday while leaving work, I turned right out of the parking lot onto the main road. Immediately my mariner hesitated, jerked forward, and a wrench light came on. My SUV slowly accelerated to 20mph and struggled to get to 40mph. It road rough and I wasn't sure if it would stall or not; however, I was able to slowly make it home. I looked up the wrench light and learned I was likely having a throttle body or powertrain problem. I found online that the dealer would fix it, but unfortunately, that was only through january 2015 and had expired (before the dealer even sold me the SUV.) I started the SUV this morning to take to the dealer to get fixed, but the wrench light has gone off and there is not proof to show the dealer of the problem. I am looking into replacing the throttle body at my own cost as a preventive nature. I wish I would have known of this before the dealer sold me the car.

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.

Was on a very busy four-lane road driving approximately 55 miles per hour; it was dark and raining. The car suddenly slowed to almost no movement, but the engine was running. Was able to drift into a lowe's parking lot safely off the highway. The engine light and a wrench symbol appeared; I cut the engine off and waited about 10 minutes and restarted. Vehicle got me to the hotel where I was staying about a 1/2 mile away. Next morning, I had someone follow me so that I could attempt to get it to the ford dealer in princeton, west virginia. Car stalled on 5 occasions; restarted it, go a mile or so and had to restart again. The service department was excellent - they immediately took the car in (I was in town for a funeral); tech discovered it was the throttle body. It was replaced, but at a cost of $594.85. This was the second incidence in less than 4 days with this same problem. On december 2, I took the vehicle to the local ford garage in greeneville, tennessee, where I live. The engine light had come on and I was concerned since the manual said to see the dealer immediately. Local ford garage cleaned out the fuel line and said I should not have any more problems. Engine light was off and I thought the car was okay. Then on december 5, drove to princeton, west virginia, and the nightmare began. It appears that the ford motor company is aware of this problem since so many owners have complained. There should have been a recall and the problem resolved. It is extremely unsafe to be on the interstate or any road where traffic moves fast when your car goes to a basic idle and will not accelerate.

On the morning of september 10, 2013, after about a 30 minute commute to my place of work, I pulled into my work driveway, and my 2011 mercury mariner stalled. The engine seemed to cut off, the wrench light came on, and my vehicle rolled into the parking spot. Unsure of what had happened with my vehicle (as it had never happened before), I immediately called my local ford dealership service department. The service manager was extremely helpful and told me it sounded like a throttle body problem, as his service department has replaced a number of these on both the ford escapes and mercury mariners. On my lunch break, I drove over to the dealership and made it with no stalling out problems. The manager then told me he would drive me back to work in the vehicle to see if it would "act up." it did not "act up" while he drove me back to my place of work, but on his way back to the dealership, it stalled out on him while he was attempting a left turn. He had to turn the vehicle off for approximately 30 seconds to let it reset. He said at this point the check engine light also came on. He got it into the service department and hooked it up to the computer. The computer generated code p2111, electronic throttle body assembly. He luckily had one in stock and it was promptly replaced. I have not had any more stalling out issues with my mariner and the issue appears to be resolved. This problem could have had deadly consequences had it stalled out at the wrong place and wrong time, particularly in an oncoming traffic situation. As the service manager mentioned to me, this has been an ongoing problem that is facing a potential recall.

I was driving 65 MPH on the freeway when my engine stalled. I costed to the side, turned off my car, and restarted the engine. My SUV ran normal for the next 5 miles before the same problem occurred. This time I was at a light and was able to stop and restart the engine. The engine started, but was running slow and the gas pedal was non responsive. I coasted to a side street where I turned off the engine. Once I tried to restart the engine, it took about four times longer to start than normal. I put the SUV in drive and it jumped slowly at a costing past with every fluctuation of the engine RPM pace. I would have had an accident if this would have occurred on my way home from work in traffic. Thankfully it was during the day with little traffic. The dealership seems to think it is a problem with an electronic throttle body. I will be trading my mariner in for a different car because I do not feel safe driving the SUV. I am fortunate that my SUV stalling did not cause an accident. However, I'm sure there are others who are less fortunate. Please help by forcing ford to recall these vehicles and replace this part before this issue causes a fatal accident. Thank you.

Needs a new electric throttle due to the same issues reported in previous complaints. Exact issue referenced below. "in two recent complaints to nccc, drivers reported intermittent vehicle stalls and surges as they enter traffic from a stopped position or while driving at highway speeds. As the problem was initially intermittent, the drivers continued to operate their vehicles in this condition, eventually progressing to the point of keeping one foot on the brake while stopped and the other on the gas pedal to keep the vehicle running."

The vehicle has quit running suddenly without warning at highway speed two times and has quit running at low speed or at stop lights or has went to rough idle in limp home mode with no power available to avoid heavy traffic. Turning off ignition and waiting 3 minutes and restarting yields normal engine operation until it stalls again. Ford service has diagnosed defective throttle body but will not warranty the defective part even though it is covered under emissions controls.

I just bought a 2011 mercury mariner in april 2013..I only had it 6 weeks when this happened. I was driving in 5 o'clock traffic and my car motor started making funny noises, felt like it was trying to stall and would not accelerate, the wrench light came on and then my check engine light. My car would barely drive, I was stuck in traffic, thankfully people saw my hazard lights and allowed me to cut through the lines of traffic and I was finally able to pull over into a parking lot. I found out later my car had gone into "limp mode" & this is a "known issue" with ford escapes & mercury mariners model years 2009-2011. It is due to a faulty throttle body. My car has been in the shop for 2 weeks now & my mechanic has been unable to get a new part because they are on a national backorder. Over 4,000 parts are on order and have been on backorder since february of this year (2013). Why has there not been a recall??? Clearly, this is a widespread issue!!! Neither the dealership or my mechanic can get a part to fix my car. I am stuck without a vehicle or any recourse to get myself into a working vehicle. Insurance will not pay for a rental indefinitely since we do not know when these replacement throttle body parts will actually ship - we've already been waiting for 2 weeks. The company keeps telling my mechanic they will ship in 3-4 days and we are still without a part. I can't help but wonder, what about the other people besides myself that have also been waiting on this shipment even longer than I have?! This is ridiculous.
