Something in our 2011 Leaf was draining the 12 volt battery, and the EV system amber warning light would come on (and stay on) after the car was driven a few hundred yards. Although the dealer service department checked it out and said that water pump #1 was running 24/7 and draining the 12-volt battery, what we found was that it was running any time the ignition was on or the car was being charged but not when it was just parked. They recommended replacing water pump #1 (at a cost of $985), and then checking the car again to see if that remedied the problem. They also suggested that what was currently happening could cause major damage to the car if not fixed. We are currently trickle charging the 12 volt battery when the car is in the garage. My question: Is there really any harm in continuing to drive the car "as-is" and maintaining the 12 volt charge with the trickle charger? If the pump is running more than it should be, it will still keep the electronics cool. Also, if the pump is not running when the car is just parked, why should it drain the 12 volt battery? I'm more than a bit skeptical about the information that the dealer is giving us.
