The Alternate Battery Malfunction warning came up.
What the heck does that mean?
I try to find it in the manual....nothing there.
I check youtube and other articles and I find out what it is.
Keep in mind...the GLK is 5 1/2 years old. I was planning on getting a new battery and an oil change this month.
The Alternate Battery is a battery that runs extra things, mainly the OFF/ON feature. Come to think of it, I don't think the car was turning off and on. But, I think it still has to be fixed or replaced as it could run some other things...who knows?
It is supposed to be easy to DIY, but you have to have some knowledge about changing batteries....rather let "The Guy" do it.
A few articles actually said, batteries should be replaced every 3 to 5 years. I expected to replace the main one, but I never heard of battery #2.
Do all new cars have a 2nd battery? Who has ever replaced one.
Batteries will go because of time, mileage has little to do with it. The cold climate probably doesn't help, but, an alternate battery that I never knew existed!

The switching between the two batteries for the other things that are powered is handled by a switch that's a module near the main battery terminal.
I wonder if the extra battery your car has was being charged by the tickle charger during the time away. For the Malibu, I couldn't understand from the two you tube videos someone made troubleshooting the extra battery, cables, and the dual battery control module on the GM how the alternator handled charging the rear battery.
SO, your rear or extra battery may just be dead. Or the module that controls charging it now is not doing the job because something confused it. Or you may have a failure of a module.
Here in the US _most_ box stores will change batteries for us. I don't know if your extra battery is a special one or not. I don't know if MB has some crazy kind of system where it has to be installed and the car has to be told in some way it's a new battery and told of its parameters so the car computer knows how to charge it.
Do you have Autozone? I'd give them a call to see if they change the batteries and know what's required.
You know it's going to cost an arm and leg were the MB store to check it. But it may just need to be coaxed to charge back in the game.
In Malibu battery is on side of the trunk behind the soundproofing materials.

Isn't the trunk battery related to the start/stop system?

I have to wonder. With all the extra things that have to be engineered/built to make a car with start/stop technology "work" is it really worth it in an "Eco" sense?

Wish my MKZ had it.
The starter is beefed up, not sure about what else.
The switch transfers power for those circuits ONLY during the time the main battery
is supplying its power to the starter.
So the extra battery in the trunk works for about 1/3 second each time during the cranking.
But they do go bad.
And the switching mechanism on the line out of the main battery under the hood has given
a few problems. That sets a code B305F, IIRC, that can be anything from a wiring problem
to the extra battery to a connector under the main battery in the engine compartment, to the DBCM, Dual Battery Control module.
I wouldn't be surprise if the Mercedes is set up differently.
I recommend watching Part II first

That said, I was sweeping out the garage today and looking at the TLX and Stinger side-by-side more carefully than I had in the past.
Here’s a brief view of the seam and fit/finish....TLX in red....Stinger in white...similar areas of each car....

Edit: they made it illegal to wear a mask while committing a crime within the City of Dayton.
One of those feel good ordinanaces. I still avoid doing any business within their boundaries,
and crime is one of them.
2014 Malibu 2LT, 2015 Cruze 2LT,
At first it was smooth, I just didn't like it switching off when I rolled up to a stop sign, then restarting as I let up on the brake... But I learned to modulate the braking so I let up on the brake pedal as the car is almost stopped, which says the brake application is less than 27%, and that keeps stop/start from cycling. Also keeping the dual AC/heat settings different from each other says the interior comfort hasn't been reached properly, and the stop/start doesn't cycle.
There are people who early on inserted a switch that interrupted the wires to the sensor for the hood latch, telling the computer the hood was open as in a mechanic working on the engine. That keeps the stop/start from cycling. Others replaced the computer chip with a tuned chip. Of course the dealers considered that a problem when it came it for service.
Some other folks found you could tell the transmission manual position to cycle through all 6 gears. That worked on 2016 and newer MB's.
I'm hurting the whole planet with the extra CO2.

I know the stop/start only works if the car is warmed up and the battery is charged.

Dent by the wheel, scrape on the door trim. Not sure if the door itself is dented but I’m guessing it is.

Think about it....the START/STOP feature is put in the car to save gasoline. The cost of a new battery every 3 to 5 years costs way more than the gas I have saved, and the impact on the environment is a lot greater......dumping an old battery!

We have to wear masks at work now. Try wearing one of those things for 8-12 hours. It's horrible. Glad to have them for my/others protection, but omg.
Also, for whoever mentioned it, I don't think my saleslady is married. So I can try to set you up if I can get a good deal out of it.
Once you get a firm selling price we can calculate the lease for you to see if it matches there numbers.
