Open tailgate creates electrical drain that kills the battery in a few hours with no lights turned on or any other obvious signs of battery drainage indication. The issue seems to apply only to vehicles equipped with power tailgate. Multiple complaints found on the internet reported by other vehicle owners. This is a major safety issue since people may not be able to start engine on their vehicle just after having tailgate open for a relatively short time. Acura customer relations department was contacted over the phone but refused to admit the fact of electrical design or a component issue and suggested me to have the vehicle diagnostic done at my own expense in the nearest dealership.
