my car was doing that a couple of days ago i went to autozone and reset my obd2 and its perfect now, i got back my power on the car and no light flashing. if i was you try to get it reset and if it happens again then you know something is wrong.

 

the warranty will cover the parts and labor all I have to pay is $50 out of like 700 which is not bad. have to wait for the car till tomorrow but they gave me a rental so I'm okay for now

 

Awesome!
