Anyone having engine stall problems?
2024 E450: First 13K miles no issues
3/10/25: Car stalled in city stop and go traffic. Red box warning “caution car could roll”. Car restarted after 3 minutes with yellow engine light. Mercedes service: electronic transient.
3/24/25: Car alarm went off while parked at golf course. Then seat belt warning. When attempting to clear seat belt warning by restart – car would not start and had “car could roll” warning (among other warnings). Played golf and returned to car with dead battery. Towed to Mercedes. Mercedes service: replaced ignition system.
4/2/25: Car stalled in city stop and go traffic with “car could roll” warning although found car was in park when police tried to push car out of traffic. Towed to Mercedes. Currently at Mercedes Service looking into software issue.
My thought if problem is caused by software, others should be having the same problem. Anyone else having an engine stall problem after 13K miles?

Any chance it is a glitch in the auto start/stop system does it ever stall if auto start/stop is off?

I now also suspect the auto start/stop system and will probably disable it when driving to somewhere important in the future. I have never disabled the auto start/system in the past.
And the car was "off" when I tried unsuccessfully to start it during the second episode - I tried to start it to clear the seat belt warning which was beeping while the car was parked with the engine turned off.
2025 E450 All Terrain Wagon, Nautical Blue Metallic, Macchiato Beige/Black Interior
I had an incident a few weeks ago that was similar to yours, but also different. One day, after coming out from a shop I encountered numerous errors and warnings when I started the car (my car never had any issues with starting or stalling out, including this incident). I took photos of most of the warnings - they were flying across the screen faster than I could take photos! One of the warnings was that the car could roll away and that I needed to apply the Parking Brake even though the car was in Park and the Parking Brake was on.
Fortunately for me, I was 3 miles from my dealer and they told me to bring it right over. They were able to duplicate the warnings but could not nail down what exactly had occurred. So they applied 15 different software updates (astounding). When my service advisor told me they did 15 software updates, I thought he was exaggerating, such as when I say, "I've been there a million times." But there it was on the repair order, 15 software updates and the technician wrote on the order "too many to list."
Bottom-line, I have my car back now and have had zero issues since then.

15 software updates... the car must had been produced very early in the batch. Glad to hear software updates solves everything. Thanks for posting the work order.

As others recommended, get the vehicle checked for updates, in the meantime, yes try not using auto start/stop first.
I'm wondering if the battery is the issue. These cars with all the electronics will do strange things because of a weak battery. The OP mentioned that the battery was dead at one point but not that the battery was replaced. Only that the ignition system was replaced. In any case, the dealership should know this and I would hope they tried a new battery. I would ask to verify they did or at least ensure they eliminated the battery as the issue. Many new batteries fail early and in ways that are not gradual.

Yes good point, if the battery was defective or over discharged for a long period of time (such as sitting on the lot) it could had damaged it.

Car still being repaired
Car is still at Mercedes service. They are working with corporate to determine a fix. I see on my phone that the car driven almost daily for about 2 miles which I am told is testing software “patches”. The dead battery is a result of the problem, not a cause. When the issue occurs the “power” cannot be shut off. I tried to access the car on my phone and I either saw “remote access disabled because engine is running” (it wasn’t), or “remote access disabled because power is on”. In both cases I received notice that the battery was getting weak and may not be able to start the car.

What were the battery test results? With these symptoms, it couldn't had passed the battery test.
Oh a second thought, two miles everyday might not be enough to charge the battery enough. This is assuming they don't trickle charge it overnight, I understand when they hook up the computer, they charge the battery, "on-board voltage maintain" on the work order but if they are just driving it to test it in such short distance and time, it might not charge the battery. Either way, still want to know if the battery test have passing results.

Car issue resolved by updating 23 software modules
23 software updates completed yesterday (Friday) March 11.
My theory of cause: I think there must have been an “over the air” software module update just prior to March 7 that had a serious conflict with the software in my very early build date E-450 (March 2024). I had no issues in over 13,000 miles prior to March 7, 2025.
Why weren’t updates performed during 10K maintenance? I was told that Mercedes only performs module updates when necessary. I think that they don’t install them “unless necessary” because of the labor required.
Why did it take 6 business days to perform updates? I was told that many of the updates took a long time to download, and often the updates “failed” and took multiple installs to update successfully.
I am concerned about the possible damage done to my 12-volt battery due to it being totally discharged twice. I put my charger on the battery when I got home and will watch it closely for any issues. I also carry a jump start battery replacement unit – inside the cabin as I discovered the trunk cannot be opened if the battery is dead.
I recommend that anyone experiencing electrical issues of any type to demand that all available software module updates be installed.

Yes charge it and measure it with a battery tester. There is another battery to keep in mind. 48V, hopefully that battery wasn't discharged.
Yes, the updates take a lot of time, even one update can take a long time so unless there is a specific issue that customer states, they won't actually check the modules for updates.

I had frequent Apple CarPlay drops in my 2024 GLE450 (several times every day).
MBUX was re-installed by the dealer, to the latest version, with the massive reinstall taking well over 3 hours (showing how much behind my MBUX version was, vis-a-vis the latest MBUX installed into the new cars), and the entire problem vanished like a charm. Never happened since.
I posted this on these forums, and another user, facing the exact same issue, also got the MBUX reinstall done on his GLE63, and his problem too vanished.

I was hoping this was not an issue anymore on a W214, given it has MBUX 3.0 while facelift GLE runs MBUX 2.0, that said, worth trying to get an update in maybe it still fixes it. Thanks for chiming in.

That's the whole point. W214 runs MBUX 3.0. So there are EARLY versions of the MBUX 3.0, which when updated to the latest version of MBUX 3.0, fixes most problems.
In a similar vein, my GLE450 ran an EARLY version of whatever changes they made to my MBUX generation in 2024 (MBUX 2.0 version, with whatever sub-version). When updated to the latest sub-version of that generation, all problems disappeared.
