Tension Guide TSB?
Wondering if anyone's run into this yet. Took my car in for scheduled service, and mentioned in passing that I think one of the belts is slipping, as I could hear the squeal at times. Turns out the tension guides need to be replaced. And there's a TSB for it. Done under warranty. But it gets better; they're like halfway into the disassembly to get to them when they realize there's no way to get to it with the engine in; this is gonna be an engine-out job 
Not even a quote on hours; dealership is just having the tech punch in and out to track the time. But it's gonna be a LOT of hours. Vehicle is a 2018 C63S Vert, just shy of 40K miles. Vehicle sees zero abuse; just driven approx 4 times/wk for 130 or so miles, almost all highway miles.
