Do you usually keep the car running when you fill up?I just received a gas cap notification (in the likes of 'Please tighten your gas cap').
It cleared itself as I removed the notification, and aside from some better than usual MPG numbers (50MPG avg at 70MPH instead of 50MPH), the car seemed to run just like it usually does.
The MPG numbers could have been due to a tail wind.
I always use the same procedure of closing the cap.
2 clicks past close, never gave me an error.
Could it be a sensor failure?
Fuel was about 66-75% full, so I don't think fuel was spilling out the tank.
