Finally, one made a few calls and determined it was indicative of when the alternator was charging the starter battery. Apparently the alternator has an electronic disconnect (not a mechanical clutch) that eliminates the load under most driving conditions, in an attempt to increase fuel efficiency. The alternator only allows the battery to be charged under very specific conditions, such as coasting at speed.

Can't say I hate the feature, but it's frustrating that it's not detailed anywhere in the owner's manual that I or the AMG folks could find.

I'm kicking myself that I forgot to ask about the tire temperature differential issue.

1) Seat memory buttons - yeah, dont like holding them, but hey, its the same on my wife's Chevy Malibu too. Pretty sure my most recent Porsche Cayenne was the same. Guess its for a reason, people messing with them?
2) Gearbox changes in C mode - I have the older model, so not the latest gearbox. But that shifts pretty badly in C mode too. I refuse to call it Comfort because its not! But its OK, just OK mind. Oddly, in Sport its smoother, just need to get use to starting off in 1st!
3) Key fob - Yeah, be pleased you dont have an older Aston, they just had Volvo ones! The older one is OK and well built, but didnt like the sticking out part, not nice.
4) In car entertainment stuff - its not great I know, but the older Merc system is way worse, its a major step up. I was struggling with it for a while until someone made a few comments - use short cuts and the voice recognition for the navigation is excellent. Once I did that, everything got a lot easier. Not sure if the new system has short cuts, but once I got it sorted, its great. The only thing I dont like about the older one is I cant customize the screen how I want it. I want the next turn to show on the screen! I am sure there is a setting hidden somewhere, but it doesnt. Have to switch the HUD to show it, which sucks.
5) User / hand interface - Yeah, dont use that crappy panel in any way. I got used to years of BMW and the i-Drive, so turning and pushing is fine for me. Nice and expensive hand rest....
6) Parking sensors - my car is very highly spec'ed but one thing it doesnt have is parking sensors.... grrrr... but the loaner E that I had a month ago was excellent. Cameras were great, sensors worked great. Over sensitive yes, but hey, think about the average driver!

But, and here is the big question - does your 2019 creak and rattle? ;-)

Give that man a cookie.

I've got IGL ceramic coating on my rims and still, even after just a short drive, the rims become a lovely shade of matte ****-brown. I've tried multiple "no scrub" wheel cleaners, none of them work without some scrubbing. I'm regretting the purchase of the multi-spoke rims now, given the frequency with which I have to wash them.

I use the cheapo Mr. Fix 9H stuff available via Amazon and apply 2 coats initially with a 1-coat touch-up each year when swapping summer/winter rims. I've even applied it to rims with a matte-black finish and it works fine and does not "gloss up" the matte finish. Be sure to spend the time to ensure you get the ceramic coating into all the little crevices and corners, beacause that's where the dirt collects and is hardest to remove. I also (carefully) applied it to the painted part of my brake calipers.

The ceramic coating makes it relatively trivial to clean the wheels (and calipers). I only use some Palmolive dish soap in a bucket of water to clean my cars and the brake dust falls off with a gentle fine-fiber/spit-ends brushing. Even removing the extensive dust and rubber marbles that end up inside the rims after a track day is quite easily.

That said, I've already gotten used to it .

I purchased a new Mercedes 300 turbo-diesel in 1983 and drove it for 27 years ... always used Mothers Pure Carnuba wax and Palmolive green dishsoap for cleaning. When I sold the car, the purchaser put collector plates on the car -- the paint job was in near perfect condition. I seriously doubt that the (often exhorbitantly priced) special "car shampoos" would produce any measurably different results, and bulk green Palmolive is relatively inexpensive at Costco. $;-)
