My 2017 F-150 2.7 Ecoboost has 4,200 miles on it and the Service Reminder lamp tit up. I stopped at an Autozone store to get an OBD readout and it was connected, read and plugged into their computer. After a few minutes of tapping keys while exhibiting a wry face, the guy said it was too new and they couldn't read it. I was also concerned because, for some time, I had felt a slight miss or stumble and thought that finally, the engine realizes something is wrong and it threw a code.

Strangely enough, the lamp went out after 3 days. I still have the miss or stumble.

Any ideas on either situation?

 

Yeah, take it in for warranty repair.
