C300h hybrid battery drain when parked
Hi just bought 2016 c300h a month ago everything was fine or so I thought I took it to mb for engine software update since then the hybrid battery percentage on the dash shows lower after a few days (80% to 45%) is this normal or do I need to take it back

I’d check to see if you have something open (or at least not fully-closed). It’s not normal to have a battery depletion like that if there’s no obvious drain on the batteries. I had my trunk open while hanging out for a few hours and it drained my batteries from 100% down to 0 as the trunk light was on
