Seconds later, it recovered back. 2 minutes later, it happened again . And again . So I parked it . ~8-hours later, I started it and the auto-lock light red again. Seconds later, the engine stopped when I back the car. I stepped on gas-pedal when I tried 3rd time, and the car moved and the auto-lock light kept red. 10-minuts later, when I drive on 288-south at ~60mph, both of the repair light and engine light turned yellow and the auto-lock light off, seconds later, the repair light off.

When I bought the car had engine light on so replace the spark plugs and put new battery problem still there. Had a mechanic check out and he said codes reading fuel problem so change out the fuel pump and put injector cleaner. Problem still there he said maybe the computer so now I don't know what to do. The problem is check engine light on and when you step on the throttle does not go pass 3000 RPM.

This is a long on going problem with the electrical problem that has been going on now for five months. Started out having the battery cluster light on & check charging system. Found charging a little low, had new alternator installed. Then with a week, battery, engine light & airbag light cluster are on, then the fun began, then all the instrument cluster goes off and you have no turn signals, no fans, no radio, no electric windows, no door locks and no break lights, (but break lights do come on when you apply breaks and the back-up lights come on. The system can come and go on and off while moving and setting still. Have had system checked and coded, they can not find a problem except that it is a electric problem, had all wiring checked, cleaned. No,frayed wire founf and no defective coupling. Again I get it a wire that is grounding and causing problem. All the fuses are ok and know have blown. The only thing I know is this problem was reported to ford back in 2006 or 2007 and they have not put out any recall on it and there dealers know nothing about what to do but they will try and find it at where hourly rate and it could be a hour or several hours to find problem. As I've said this is on going it clear up and last for a week up to six weeks at a time.

Throttle had it fixed with recall, it lunges you into traffic while stopped. Again it has done that now failed, this is a dangerous car. It is garage kept and well maintained went down to get gas, mail and while stopped it jerked me out of the stopped position into the mailbox then the wrench, traction and engine light came on and it bucked till I got it 10 feet to the garage no, it will not start!!! To even get it to the dealership or garage, its a safety feature I was told, the way it lunges is dangerous, I almost went through he garage wall which is concrete, last time I hit my teeth on the steering wheel and knocked one back out of alignment. Which the ford person thought was funny last time. Ford knows this is a dangerous car, it should be replaced and these should be crushed like the demon car they are. People spend hard earned money on these vehicles all for this to happen?

I have researched online and a lot of people with my same car are having the same problem. While driving my whole dash board goes out . I can no longer see how fast I'm going. Everything goes to 0 the gas goes to e and my reverse lights stay on until the dash board comes back up. If and when it comes back on my check engine light will be on. This has been happening every since I purchased the car 3years ago on and off.

Bought the vehicle used in may 2010. Realized early-on that the transmission was not smooth, but willing to settle for less than perfection since it was a 2005 vehicle. In late 2012 or early 2013, I received 'recall' notice that PCM (I.e. - powertrain control module) could need to be reprogrammed due to stalling, herky-jerky transmission, etc. Took car to dealership, they ran diagnostics, charged me $100, and told me that my car wasn't effected because no error codes were noted and check engine light wasn't on. I was not happy, and refused to take my car to the dealership for repair. Problem persisted, until check engine light came on in october 2017 at roughly 125,000 miles. Took to local mechanic, was charged $150 for sensor replacement. Light came back on a day later. Took back, replaced sensor for free (nice!), but light back on a day later. Took to a different mechanic, was charged $250, replaced multiple sensors, light back on the next day. Took back to 2nd mechanic, when they shared with me that it was likely the PCM and the dealership would need to fix. Called dealership 3 days in a row, on hold for nearly an hour the 3rd time, was never connected to a service writer or tech, left 3 voice mails for service manager and was never called back. Researched issue and found the federal safety agency action number pe11018, where ford initiated a customer satisfaction program 12n03 to extend coverage terms of repair of engine idle RPM surge caused by PCM needing reprogramming with software containing updated idle speed control. Per the federal safety agency, symptoms associated with the condition may include check engine light, diagnostic codes (dtcs) p0505, p0506, or p061b. Ford issued bulletin tsb 11-10-21 that included updated powertrain control calibration.
