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.
