I noticed this on Memorial Day weekend and asked the staff inside if the padlock was gone for good. They confirmed that they will no longer padlock the unit.
If you need a charge at Newton Nissan and are a Nissan customer you are welcome 24/7. Owners of other makes of electric vehicle should extend the courtesy of asking first before using the DC Fast Charging unit. The staff at Newton Nissan pointed out that there is a 240v “level 2” charging station in the front parking lot that anyone in any electric vehicle is welcome to use.
