MBUX Failures
New 2026 GLE 450. MBUX ongoing issues:
1 - Comfort easy exit feature. Set on, works for a short while and quickly stops working - the check marks are not sticky. I am told this is a known bug on the GLE. My previous GLC worked fine.
2 - Today found my Favorites/Individual choices gone!?!
3 - Right side external mirror changed on its own.
All of this is bad and I hear the reason many people take these vehicles to the dealer to be parked there for multiple days - a real shame. I will not do that; to me these are doodads that add little to the basic vehicle functionality. This is the shameful state of today’s infotainment-loaded vehicle nonsense.

Just provided a data point for others. It's a public forum, not a Service Department with actual diagnoses.
Many of the problems we've seen that are similar to yours are Profile-related. Maybe Most or All.
It may or may not apply to your situation. But it might help your troubleshooting.

I'm not wrong. I didn't accuse you of anything.

This is my wife’s car and driving it with a single default profile is fine for both of us (that’s what the previous GLC had and that worked well). Let’s see if the settings stay put. I will report back.

Look, having come from many BMWs for the past 20+ years, I have to agree with GLE450Owner - these issues are pretty bad and should be easily addressed with a software update. The cars have the ability to store more than one profile - so make it work.
I do agree that the luxury, the ride, comfort, etc. are very good. But in this day and age, if competitors like BMW can make this stuff work....so should Mercedes. I never had a problem with multiple profiles on any of my former cars. And I'll say this again - BMW assigns profiles to an individual keyfob - so when you approach the car, the seat, climate system, stereo etc. all change to your preferences. It's 2026 - Mercedes can't do this? I can't even press a seat memory button in the door to have the seat move. Like that's really basic....right?
Anyways, I didn't come here to bash the brand - I just got one after all...just sharing my opinion and early impressions. Still lots to love about the GLE 450 Coupe

It did not last long (just 4 hours)… Not allowing profiles shuts off the use of the mobile app (useful for remote checking). With profiles in place, even if logged out, I found that the default profile quickly lost the comfort exit settings… Yeah, it’s bad and unacceptable, and taking the car to the dealer will not fix it. Complexity is destroying the enjoyment of operating a vehicle today.

I am looking to buy my first Mercedes for my wife. My father-in-law has a couple BMWs and I love the key fob profile feature. I just assumed the GLE had this ability. Disappointing for sure.

I've said it on this board dozens of times... Mercedes builds a pretty decent car but I really wish they would farm out the software to someone else who knows what they're doing.

In our BMWs, the profile that gets loaded is the one assigned to whomever uses their fob to unlock the car first, presumably the driver. But if driver 1 unlocks the car and their profile is loaded, but then driver 2 decides they want to drive, they can simply use their fob to unlock again and their profile is then loaded.
Now, let's say both owners get into the vehicle when it is unlocked and parked in the garage for example, and the driver wants to change profiles. They simply select the correct profile from the home screen a Voila - settings are loaded. If they need the seat moved before using the home screen to load a profile, they can use the door seat memory buttons to move the seat before the enter.
And again, what is assigned to a profile is not just seat position - climate preferences, stereo settings (including music source, volume, and EQ settings), vehicle lighting and heads up display settings etc. are also loaded.

On a related note: we use CarPlay and more often than not, we do not get the little menu option at the bottom lower corner that allows you to select all of CarPlay's functionality. When it is working, it should look like several tiny boxes but often it just looks like a single, empty box and pressing it has no effect.

Assuming both owners each have their key on them....

Because of this when my wife and I both have our keys with us and the passenger reaches the car first, then the passenger’s profile gets activated. The driver then needs to select their own profile on the screen.
The Mercedes defaults to the last driver profile used which also can be changed on the screen when changing drivers.
If the car is driven by one person 90% of the time I prefer the default to the previous driver than having the passenger inadvertently change the profile.
So BMW in this case is more slick and Mercedes is more dependable.

My BMW behaves as described above with one slight change. The BMW has a feature that it will unlock from a distance, like 10 ft, before you reach the vehicle. The lights turn on before you touch the door handle.

I'd prefer to just approach my car without all the public fanfare of lights on when I'm near it.
Is there a way to defeat the process?

So I said I would report back… Yesterday I had the Dealer reset it all, set 2 profiles. It worked all day yesterday. Today (24h later) my profile Comfort Entry Exit feature settings were no longer set.
Some in this forum say profiles work for them. Do they set/use the Comfort Entry Exit feature? If they do, and it works for them, more power to them!
Another annoyance… the front tow-hook cover is constantly popped up. Yes, the clips are there and not broken, but clearly not strong enough.
This is a ML class on a series of SUVs I’ve owned starting with the original ML. The previous two (GLA/GLC) were assembled in Germany, this one is a US assembly. Is that the reason?
For reference… This is a 2-month old car.

I doubt if US manufacturing is responsible for software glitches. Spend a little time on the E Class forum (German assembly) and you will find software glitches and profile complaints there too. My 2024 GLE 450 occasionally loses the setting for comfort entry/exit. Takes five seconds to reset it and I'm good for a while. I find this to be very minor annoyance and certainly don't get worked up about it.

Yea, the MBUX has been kinda finicky on my 2022 GLC, I've had the infotainment system lock up on me a few times requiring a hard reset and I've noticed some weird lag when switching between menus. Have you guys tried updating the software, mine's still on the latest version but I'm wondering if a new update will address these issues.
