Shift solenoid d : veh is part of recall 16s19 and recall 16n02. The vehicle is shifting still at without warning at various speeds. This device was not included in the original recall, and Ford is refusing to cover this defect although it is clearly a part of the same problem. Ford had ordered these transmissions from a manufacturer in china, and they've been nothing but trouble from day one. This occurs while the vehicle is in motion and there is no warning when the malfunction occurs. The car was sold to me this way in February of 2013, and at the time the dealership had told me that this was an open ecm issue and was nothing to be concerned with. I took them at their word and am paying the price for it. I have checked my car fax, and there is absolutely no mention of this as a problem. . Read more...
On oct 30, 2014 I was shifting to 2nd gear and the engine bucked, lost speed, then the "wrench" symbol illuminated, indicating the limp home mode activated. I pulled into a parking lot, shut off the engine and restarted it and the light went out. I drove it to an auto shop and they could not detect a malfunction code. Today, Nov 5, 2014 when leaving my neighborhood, the same loss of speed occurred in 2nd gear and the wrench and check engine light came on. I drove back to the local auto shop and they determined the throttle body was defective. The solenoid was bad. Fortunately, my incidents happened at a low speed. This could be catastrophic at high speed, running the risk of a high-speed, rear-end collision.
Front hood has paint peeling issue within 2 years of purchase. Auto trans doesn't shift properly in at least 1 of the first 3 gears. It bucks when cold in winter weather until car warms for at least 30 minutes. . Ford has had the car on 3 occasions without fixing the issue. They replaced the first 3 solenoids in trans without success. Purchased new. These 2 issues remain a big problem. On another note, interior cabin flooded due to rain entering the cowl from a design flaw. Dealership detached a hose.
