Had something bizarre happen yesterday. I unplugged my USB cable before going into a gas station. I came back turned my car on, and when I plugged in my usb cable my blue gauge lights shut off for a second and I think all of my electrical stuff did then they came back on the car went into limp mode. Wasn’t even driving haha. I turned my car off once I got home and turned it back on just to see what would happen and the wrench disappeared

Did you check the OBD2 for a pending CEL code? Even though the wrench is gone, a pending code could be registered while not throwing a CEL yet. Just trying to help.

I would use a different cable and check to see if there is anything in the socket that could be shorting it out.

If it was the USB I'd be surprised that the ECU isn't better isolated from that.

It could just be coincidence or an issue in the electrical system.

Some of these 18's have some electrical gremlins. Not the first one I have heard of to throw the wrench light while stationary.

If the car can be taken out by the USB port someone could make a small plugin device that would frick up any Sync 3 car.

I think the real question should be, what was on the other end of the USB cable? A tuning device? MP3 player? Phone? Flash drive?

I've seen broken cables and bad USB ports crash computers.
