Driving around 50 MPH, all of a sudden the engine throttles down and the powertrain light comes on. The engine is still running, but no response when you press the accelerator. Had to pull over, shut off the engine, restarted the engine and it functioned normally. It happened two more times in the same trip. It has been happening intermittently. Bringing it in now because of potential road hazard.
2011 Mercury Mariner engine complaints
Page 2 of 2: complaints 11 to 14 of 14, newest first, as owners wrote them.
Started vehicle in the morning for work & yellow wrench light came on, combined with "limp mode" symptoms of no throttle response. Googled & found multiple complaints for similar issues with this motor. Called local ford dealer who said the throttle body has had 3 different part numbers which leads me to believe that this has been a know issue for a while now. Ordered the latest version of the throttle body & will have it replaced by my mechanic who said its a 1/2 hr install. I will be keeping the receipts & hopefully ford will be kind enough to reimburse those who have had this fixed, if the issue does end up becoming a recall. What a headache.
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.
Car seems to stall all power stays on but the car shakes and then stalls and the wrench light comes on which is a powertrain light. Took car to dealer they say there is nothing wrong with it. They reset the light. One week after bring the car to the dealer the wrench light comes back on and the car stalls this time I was going 55 miles an hour on a parkway thankfully I was able to pull over before the car stopped. Brought to dealer, nothing is wrong with the car they recommended me to leave the heat off because there could be a problem with the heat. (don't understand that) last week the car stalled again and the wrench light came on. I am currently waiting to bring it in for service. This is not good nor safe.
