Batteries in our 2010 Nissan Pathfinder STL have been going flat since we bought it. We have replaced three batteries in two years and have had to get roadside assistance because batteries have gone flat. Checks haven't found any problems and the workshop cannot give an assurance that is will not happen again. Can you offer an insight?
Clearly, something is draining the battery to cause it to go flat. Check that interior lights are being switched off when you close the doors, and anything else that might not be switching off like it should. It would be a good idea to take it to an auto electrician.
