Cross Country in GLE
We want to do a cross country in the fall and after reading bunch of posts in this forum, I have developed some concerns. Specifically, I've read that the 48V battery can fail and make the car totally inoperable. This might be OK if I'm in town and can tow it to the dealership. But I'm worried something like this might happen when we are thousands of miles away from home!
Am I being paranoid or is this a legitimate concern?!

OTOH I wonder if NOT taking cross country trips, or at least long drives of an hour or so, is the cause of these reported battery failures.
I know that cars in general won't keep up, if you only take short trips.
These new cars, that are constantly listening to their app, sending reports and otherwise staying "busy," may need more charging than we are used to, to keep from damaging batteries because of a constant discharge state.
I know that @Ron.s has a battery problem, and he seems to put some miles on the car, but I wonder about the other reports - is it a lack of driving?
Our '19 GLC alerts the ME app every few weeks, even though we take a longer drive regularly. It' s12v only, but it's not sleeping over there in it's stall.

My 2020 GLE 450 had 16,000 miles, 15 months old and no 48 volt battery problem. Ironically the 12 Volt AGM went bad but didn’t leave me stranded.
Don’t let the battery spoil your trip but maybe keep it in the back of your mind. Knowing the risk I stuck more with Freeways than secondary roads this year.

If you special ordered you can also just assume that the car was built about 4-8 weeks before Dealer delivery since you are on the West Coast. The complication of backing up from delivery date is that cars were built and held at the factory for missing components last year. In my case, my car was completed early November 2020 but sat until December...probably waiting for a 48 volt battery that was in short supply.

On the whistling sound from the driver side mirror, I haven't experienced it yet. But there is a thread on putting a carbon fibre mirror skin that fixes this issue.
