Anyone else have advice before I trade this thing in?

I maintain my position that sitting in the carwash just depleted ProStar's battery charge and the ICE had to work harder to recharge the battery and provide power to the vehicle.

Now their MPG is back up. Just takes a little driving. Same thing happens to my car if we use EV for too long.

:roll:

 

Good point Galaxee., if he did not turn his car off, the battery went low and the engine recharged it thus the lower mileage.
