I have a 2020 GLB250 and mine was saying "12V battery" on and off for a few weeks. I checked under the hood with a multimeter and my main battery did have a low voltage while the car was off. I replaced it a few weeks back. No more notification.

Pros: no more notification
Cons: low voltage, on and off

I had the same issue on my w213 - same warning every now and then until one day it just didn’t start. Replaced the battery and solved the issue.

Pros: solved the issue
Cons: warning every now and then

I drive a 15 year old gas powered Audi Q7. Still runs like new. My issue with EVs is you can't just keep them tuned up when they're old. No matter how good of care you take of it, the battery will decay and lose capacity.

Pros: runs like new
Cons: battery will decay
Vehicle: Audi Q7

In the 166 body MB ML/GL, its under the passenger seat, with barely enough room to reach the rear terminal. It's also so far forward that you can barely grab the fuckin thing. Oh, did I mention that it is a group 49 battery.

Cons: hard to reach

Spouse has a 2021 etron, (some issues, inc battery recall), I had a 2022 etron with many issues which prompted my change to a 2025 SQ6. I’ve written to Audi Canada so many times regarding the etron issues with no resolution on any of them. I like the SQ6 but this will be my last Audi - worst experience I’ve ever had with any vehicle and manufacturer.

Cons: worst experience
Vehicle: Audi

It is a great car to drive.\n\nThe battery range is very, very poor. On a cold day the range may be in the 120 range. It is exp naive to maintain as most parts on it are coded which means Audi dealer only

Pros: great car to drive
Cons: battery range very poor
Vehicle: Audi

I don’t have an AMG, but a 2024 CLA 200d and having battery drain problem is annoying to say the least and haven’t even had the car for a month when it all started happening. It’s been at the dealer for the past 3 days and no voltage drop there. They gave me the signal blocking key case and they upgraded the software and still can’t find the problem. Third visit in the month and new battery installed too.

Cons: battery drain problem, annoying, problem persists after new battery
