The wrench light on my 2013 hybrid Titanium came on last Friday night. The drive train shut down and I had to pull over (steering still worked). I shut off the car, then started again and was able to drive home normally with the wrench light still on. The next morning, there was no more light and it hasn't returned.
I made an appointment with my dealer's shop to get this checked for error codes, but they called back to say it would be pointless unless the wrench light is on. But also only if I don't stop and restart the car because they say the stopping and restarting cancels out any information on the computer.
I've never heard of this before. Does it make sense? I thought error codes were stored in the computer anytime a trouble light comes on.
I'm also concerned because the car is on the cusp of the end of the warranty. My worry is that the light will come on again for the same problem just as the odometer kicks over and Ford's off the hook and I'm on it for any repairs.
Is it possible that the wrench code came on when there was no problem? Some kind of "glitch?"
