Has anyone else had problems with the front battery coolant pump running for hours every day ? We have a 2016 S60 with about 12k miles on it. The pump running excessively just started about 5 days ago. Before that we hardly ever heard the pump run. Now it runs (and makes a loud high pitched noise from under the front hood) for hours everyday. The car will just be sitting in the garage (about 60 degrees air temperature) not charging or anything and the pump will start up and run full out for two to three hours for no apparent reason. We're concerned there might be a battery problem that is causing the batteries to heat up even when the car is not in use.
