I've had my car less than 2 months and so far Homelink has forgotten the rolling code on my garage door twice. I have 2 doors programmed and the second door doesn't have the issue, only the door where I actually park the car.
Has anyone else had this issue with the 2020 GLE? I searched the forums and all I could come up with was some issues in 2010 with the e class.

2020 GLE here as well with the same issue. We got our SUV new in 2020.
I even replaced the bulb to those "Garage Door LEDs" (below) to no effect. It loses the programming after several days. I've given up and just bought a spare Chamberlain remote.

I recall our car forgetting one of the 3 garage doors constantly when we got it in 2020. Mentioned it to the SA and he told me there is a software update out for that (service bulletin?). That took care of the issue. Unfortunately can't find the invoice for details...

Problem solving advice like this (albeit just a garage opener) is what this forum should be about, IMO, and not the constant bickering that I read on many posts.

This has been an ongoing issue for me and I never considered the led bulb to be the root cause. I changed it to a standard incandescent bulb this weekend, and it now works perfectly - every time. THANK YOU VERY MUCH!!

What I did in addition to the garage door friendly LED lights is to also extend the antenna wire (all the way to the wall on top of the door). This helps (in my case) extend the opener range and also minimize the LED light interference.

Even with garage door friendly LED, there could still be interference with the signal which could result in shorter range.

My car is due for regular service next month. I'll inquire with the dealer and update everyone here if they solve the problem.

Did you complete the rolling code setup?
Using the "Learn" function on the opener?
I just re-set up another opener with my car, and had to refer to the Onboard Owner's Manual because I hadn't completed the setup.

I suspect my problem is software, as well. I have been keeping track of how often it loses the code. Every 10 days! That's not a hardware problem or an interference problem.

After 11 days, the left garage door code was forgotten. The left button successfully opened the right garage door, as I had programmed it to. So it's not specific to the button!
I pulled out the original, hand held remote that came with the garage door opener. It successfully opened the left garage door without needing reprogramming.
I have to admit, I'm a bit stymied. I could say that the fault was with the garage door opener itself... except that the hand held remote and my wife's car both work fine, successfully opening the door regardless of how much time has passed.

I had the same experience until I realized I hadn't completed the second step. See post #36 above.
Hope it works for you.

So I've never had issues with Homelink and my 15 year old Liftmaster with rolling code. It does require the second step by pressing the Learn button. The mirror Homelink transmitter I believe is pretty much the same one in every model of roughly the same generation. Mine is a 2019. It actually gets installed at the VPC. When I did European Delivery with my C63 it didn't' have the Homelink buttons until the car arrived in the USA, so the VPC replaced the mirror. However, as somebody above suggested, I clear out all the codes every time I get a new car and reprogram all the cars/remotes. I do this primarily to remove the car I just sold as there isn't a way to remove just one code. I also don't use LED bulbs anymore. I did for a while and surprisingly they didn't cause any issues, even though several techs told me not to use them.
The other thing, though, is that newer garage door openers use the new Security+ 2.0 protocol. I have no experience with that and how reliable it is, but that could explain why it's only some openers that are having issues. I've been considering getting a new opener with built-in Wi-Fi, but ended up retrofitting the Chamberlain MyQ Smart Garage Hub, so now I can open my garage from my iPhone/CarPlay. Homelink is starting to become obsolete.
As far as calling Chamberlain/Liftmaster for support is concerned, they don't own Homelink. Homelink is owned by Gentex since 2013, so when they tell you to call Homelink, that's who they mean, as they supply the tech to MB, Chamberlain etc..

After many attempts, following the owner's manual every time, I broke down and called Chamberlain. As someone else pointed out, Chamberlain redirected me to Homelink. The Homelink tech was extremely helpful. He gave me a slightly different set of steps to follow. The bottom line is that the owner's manual was not describing the steps correctly. Or, at least, I had to do it a bit differently.
As mikapen said, there was an extra step after the initial programming. I had to push the Learn button AFTER the initial programming. Now that I followed those slightly different steps, everything works and the car is not forgetting the code.
Thanks to everyone!

Okay, here is what I hope is the FINAL UPDATE for my problem.

What I believe rolling code works, is when initially paired with the opener, it has a initial code. Every time when you use it, the code shift by x values. The garage door opener usually have a "range" which the previous and future x number of codes are allowed in case of a missed transmission (since code changed on every transmission/receival). If you didn't program the car with the rolling code, it will use the fix code, and eventually it will be out of the allowable range.
And just to be clear, the manual does stated the rolling code step. It also show you in the pairing step (left side of the image below) if you need to perform the rolling code step or not based on the light.
