Anyone experiencing this massive issue? Appears MB has zero idea how to deal with it. 48v battery is main power source for starting/stopping your engine at stop lights, etc. It's on current recall but this is after I had to replace mine on a 2yo GLS450 in March for $5k. Been severely disappointed with Mercedes USA Corporate, Park Place Mercedes in Dallas & Autobohn Mercedes in Grapevine. Just absolutely embrassing lack of responsibility by all of them. Anyone else successfully gotten MB to work with you on issues? I'll never buy another MB and would caution everyone else to do the same, or at least to wait until they can figure out the 48v battery issue.
