Had to go to the dealer for a "check eng" on my wifes CRV...$90.00 for them to tell me the gas cap was not on tight. (Even though I had tightened the cap, they still had to re-set the sensor)
The reason you will never see an all eletric car, all the spark plugs, oil filters, etc Service is where the real money is made on a car.
Good luck Cware
