I have a 2020 Ram Rebel Ecodiesel. I've noticed after turning the truck off, there is a high pitched humming noise which continues for approximately one minute after being off. What is this noise? Also, unsure this is connected but I've noticed after turning the truck off the, fuel milage range to empty drops about 15 miles the next time I start it up compared to when it was parked. The fuel gauge needle will also drop a small yet noticeable amount. Is it possible fuel is being used after the truck is off to perform some sort of emissions function? Thanks for any replies. Still learning this new truck.
