I have been driving my 450 for almost three weeks now. Initially, the active steering assist icon was always green, but now it remains grey regardless of where I drive. How can I enable it? Additionally, the auto-hold feature has never worked on my car, no matter how I engage the brake.
Did you turn the feature on? That's the Active Lane Keeping Assist. That's the one that people complain about, because it can be a pretty violent correction. I leave mine off.

I think the biggest thing is that there most be lines on in the road. If not, it won't know where the lane is. There are additional settings in the menu that may effect this. I keep mine off other than for long highway trips.

You're right.
Even when I have mine on, the icon will grey out if it can't see lines.
It's interesting that, around 2005, the Feds started requiring outer lines on roads, in order for an entity to receive Fed highway funds or grants. It more than tripled the cost of striping, because they also required glass beads to be added.
They were envisioning these driver assists well before it was mainstream.
I think the rules had been in place since the 90s, but enforcement and funds withholding started in the oughts.

There is also a minimum speed for it to activate. Around 35 or so.
After you exhaust all the possibilities take your 2023 GLE to a Dealer with an excellent Service Department. My 2021 E63s AMG Wagon lost Active Steering Assist after working flawlessly for a year. After nearly 3-months last Fall the Shop Forman and MB Tech Center finally fixed the problem that was in my case a Hardware Failure. The worst part of the ordeal was driving a brand new 2022 GLC loaner for that period. Fortunately still had my Ducati and V8 Chevy SS. Hopefully your fix will be simple. Good Luck!
Active lane keep assist only works if you have the distance assist on, and the camera are able to see the lane clearly on the road.
As for the HOLD function, make sure to keep the brake pedal at a somewhat constant pressure when coming to a stop, and after the car come to a complete stop, quickly push down on the brake pedal more. That should activate the hold function (verify it by the "HOLD" icon)
It only goes green if DISTRONIC is active. Grey means it's turned on, but passive. Are you saying that it doesn't turn green when you activate DISTRONIC?

What did they do to fix it? Do you recall what was listed on your work order?

Is DISTRONIC advanced cruise control?
I found this active steering assist is only available (green) when I drive with advanced cruise control engaged. I swear I noticed it was green without cruise control engaged when I picked up this car three weeks ago.
And whatever how deep I pushed the brake padel, the auto hold cannot be activated.

When you said 'lost active steering assist', did you mean it wasn't even activated ( became green) when you used the cruise control on highway ?

Yes, however MB doesn't refer to it as advanced cruise control. Did you mean adaptive cruise control? Yes, DISTRONIC is the brand name for MB's adaptive cruise control. No, it's never green unless cruise control is active. It doesn't work by itself. It works in conjunction with cruise control.
As for the auto hold, a few people seem to have a tough time figuring out how it works. It doesn't work based on how deep you push the brake pedal. It's activated by a quick stab once you have come to a full stop. Come to a full stop, and easing off the brake pedal as one normal does for a smooth stop. Then once the car is fully stopped for a moment, give the brake pedal a stab. Don't push it slowly in. That doesn't work. Has to be a quick stab.

New steering wheel, all internal modules, and brand new switches. Was tough during parts shortage...they changed out steering wheel twice as well as internal modules. The trick was external switch replacement. Forman didn't enjoy all the wiring involved. Believe each switch has either 4 or 6 wires I forget.
Hopefully OP's problem will require a much simpler fix.

Mine works when the adaptive cruise control is engaged. now I am not sure if it is indeed a problem, but I still don't know why it was on green without cruise control engaged when I picked up this brand new car three weeks ago.

Not a problem. Yours works as designed. Not sure why you think it was green w/o cruise control engaged, but that's not a thing.
Kind of related, and I haven't found an answer.
Does the active STEERING assist keep one IN the lane or does the vehicle have to drift to the side of the lane? I ask, since most times I read that it "corrects" the path by applying brakes, etc. I have this feature in another non-Benz vehicle and it operates fairly seamlessly with keeping one in the middle of a lane. Benz makes it sound like it's a reactive feature: like one has to drift to the edge of the lane and then it brings one back.
Any comments are appreciated as we're thinking of ordering and don't know if we'll get much use from the Driver assistance package. (We'll get the dystonic CC for sure though.) I do understand the lane change feature, etc. It's just the lane keeping one that I'm confused with.

There are two systems, Active Steering Assist, and Lane Keep Assist.
Lane keep assist, when enabled, is passive, and activate when you drift toward the edge of your lane. It will first warn you by vibrating the steering wheel (on "slow" drift), and apply brake on opposite side if continues.
The steering assist, requires the advanced cruise control, and when active, it will keep your car in the middle of the lane with steering input instead of brake.

Ahh, I see, That makes sense. Thanks for pointing that out and the quick reply!
Did you turn the feature on? That's the Active Lane Keeping Assist. That's the one that people complain about, because it can be a pretty violent correction. I leave mine off.
you got HUD , can you post picture of HUD during day and night .please thank you

I'll try.
Right now I have it set too bright at night, so I'll take the opportunity to adjust it at night.
It's not something I like to do while driving, cuz it's kind of fidgety.

If the "Hold" function is not working properly you may need a new auxiliary battery. When that battery dies, Hold goes away. My Hold stopped working and a new aux battery returned this great feature. Also, my experience is that the steering wheel only turns green when Distronic is activated and you are on a road whereby the car can see lines or you are right behind another vehicle. When it is active, the car will stay in the lane, even around curves, and the steering wheel will move to do so.

Does the car stay in the lane with distronic cruise ON, but not with a speed set?

We turn on the cruise control and steering assist turns on at the same time and on kinda hands free driving, scary but neat on ‘24 GLE 350
