History My daughter was coming home from town when she called and said her car was doing something weird defined as driving slow with no power. I headed her way and she began driving slowly home. I saw her and told her to pull over in a parking lot. When I got in and put it in drive the car would just jerk like it was wanting to move but not go anywhere, then the gas engine would start up and the RPMs would start to go up at which point I turned the ignition off. After having the vehicle towed to my home, I hooked my scanner up and the code P0A78 (Drive Motor A Inverter Performance) was found. After some research I found that most likely the inverter under the hood was bad. So I purchased a used one with low mileage and replaced it. Now when you turn the key on nothing happens, the P0A78 code is now gone, but there are two new ones. P161A (Incorrect Response From Immobilizer Control Module) P1A10 (Hybrid Powertrain Control Module - Battery Prohibited) I have tried looking around these forums, other forums, and google and I keep getting conflicting information. I assume that the problem is a mismatch between the PCM and and the SOBDMC. The questions are one can this be fixed somehow with Forscan and AB files? Is there something else I need to be looking at? I really hate to take it to Ford dealer as unfortunately the closet Ford dealer is 45 mins away and Wreckers want an arm and a leg these days with gas prices. Thank you for your time looking and offering advice.

My 2011 Ford Fusion started out by throwing the "Wrench" error everytime I was driving up inclines at highway speeds (specifically the I-15 to Vegas). This happened on almost every trip and when I took the car to the dealer while under warranty, they could find nothing wrong. Then, when the car was 600 miles out of warranty, I started getting the "Stop Safely Now" error (which causes the car to lose power - you have to turn it off and on to reset and regain power) under the same conditions. Still no issues identified. Then one day I turned on the car and tried to back out of a parking space and got the "Stop Safely Now" error. At that point I could not go more than a minute or two without getting the error. Took the car to a nearby Ford Dealer who pulled the following codes: P0A0A, P1A10, P1A14 and recommended replacing battery harness per TSB and the water pump for cooling the transmission. They also recommended replacing the 12 vdc battery, even though I had just replaced it with a new battery from Ford Dealership two weeks earlier. I did not replace the battery again, but I did get the other two parts replaced and my wife continued to use the car to commute to/from work (there are no significant inclines on her commute route). While the car operated for 11 months without a "Stop Safely Now" error, my wife complained that many times when driving on the freeway, it felt like it was not shifting smoothly (I realize it has an electronic continuously variable transmission so it does not shift in the traditional mechanical sense). During those 11 months, we sadly made no Vegas trips, so no major incline test. However, last week we did decide to drive the car to Vegas and sure enough, on the first major incline at highway speed, the "Stop Safely Now" error triggered and the car lost power. We pulled over, turned the car off and on to reset and immediately drove home to switch vehicles. Now we are sitting here wondering what to do as no one seems to have a real solution to this problem. Taking it back to the dealer seems like a costly exercise in futility If you have had similar problems and found a positive resolution, please let me know.
