My Edge suddenly loses power, wrench light comes on

Recommended Posts

This has happened to me on 2 occasions. I'm driving on the highway at 65-70ph when I feel a clunk and my power is suddenly gone. No response when pushing the accelerator, and the engine is running really rough, like the timing is suddenly off. I pull to the side of the road, the yellow wrench ight is on. I turn off the car, and immediately restart. The engine runs fine, no warning lights, no problems at all. I took it to the shop 2 days later and there were no codes showing and they drove around a lot, unable to replicate the problem. Has anyone else had this problem? My Edge is the 2013 3.5L 6 cyl AWD 80,000 miles.

Sounds familiar, a couple of years ago I had similar symptoms.  

    First the Adaptive Cruise Control said it couldn't work.   Stopped, turned off engine, and sometimes it would work again, sometimes not.

    Then the power loss, though I could still drive slowly.  Didn't notice an engine clunk, but I'm hard of hearing so I miss a bomb exploding.  LOL

    Went to the  Ford Dealership in Redding CA.  I think by then I did have an engine code.  Long wait to get service so ...

    I drove 200 miles back home and took it to my Ford dealer.  There was a known problem which they fixed free of charge and gave me a loaner for 3 days during repairs.

        (Fortunately it didn't do additional damage to the engine to drive it home.)

 

Sorry, I don't recall the actual engine problem.  I'll try to remember to call them tomorrow and ask them to look up the service record.

very likely throttle body issue.  common mostly on 2011s, but does happen on other gen 1.5s.

 

code is only stored till successful restart, so to catch it, you have to read codes before attempting a restart.

Thanks, that helps. It’s hard to get to somewhere to read the code without restarting. The engine is completely disabled when this happens. Will it show up in the warning screen on the dash?

Not sure what you mean by that bold part?

 

The error codes will be saved, even if the engine starts normally again.

 

You may be able to loan a reader from Autozone, but OBDII devices are so cheap these days it well worth having one in your tool chest.

On the left side of the instrument cluster is a series of drop down monitor choices, the bottom being “Warnings “. Once it showed up a message about collision detection system was inoperative during a heavy rain. I was wondering if a warning would be triggered there. Both times this engine problem happened, no codes were saved. Possibly cleared after I restart and everything works normally again

No, the error codes aren't displayed on the dash.

 

I had an occasional misfire immediately after gassing up, and suspected the evap valve, but no codes, then a few months later I upgraded my OBD device to the OBLink MX+ and it showed that I do have a stored evap code.

I then connected using Forscan and it too identified the evap code.

 

What code reader are you using?

 

It is highly unlikely that there's no codes stored after a total engine shutdown. 

 

No, a restart does not clear codes.

It was the reader at the repair shop. Not a Ford dealer. I can purchase those? How much do they cost?

I purchased an OBD2 reader and caught the code the next time the failure happened. It was the throttle actuator stuck open. It seems I need a new throttle body. Thanks everyone for your input.

glad you got it figured out.  rockauto.com generally has the lowest prices, but online dealer pricing is not terrible.
