My o ring for the crank sensor is bad at 2800 miles has anyone had this issue before? Does anyone know what would be the cause of that and how often does that occur its getting fixed at the dealership now...don't know if they are Bull-S-in me or what

 

First time I have heard of this issue.

 

I've heard of it. It's rare but it happens.

 

This is the fix for the random misfires a number of folks were having on their 2013. It took Ford awhile to figure out what the problem was.
