My E550 rotors start causing vibration after the first 5000 miles and get unbearable by 10000 miles, I've gone through 3 sets in 7 years, always used OEM parts from the dealership.
You are describing what many other owners are saying. You recall those were OEM parts ( Mercedes stamped Akebono pads ) that I removed on the E550 in this video. So, have OEM parts failed us? Have you ever looked at the front rotors that were replaced?
I love my 212 e550, shes a reliable, strong, tank. So easy to work on for the most part. Mine has definetly grown some little squeaks and rattles and nags here and there that I have found to be particularly hard to locate. And yes- mine eats through front brakes all the time too. Ive read some people replacing the calipers with cls calipers but I just dont know about all of that! It gets especially tricky when you hear about people changing up the master cylinders just for the brake wear
For information gathering I was shocked to see the rear pads on my 2020 GLC 300 at the sensor limit after 30,000 kms and I am a very light brake user. I changed the pads myself (rotors ok) but my local MB dealer said this model is prone to early rear pad and rotor replacement. The front pads had 75% life remaining. The model I have has cruise control and will automatically apply the brakes to slow the vehicle. It left me wondering if this was a possible cause if there is a higher rear bias. Not necessarily an answer to your question Kent but an interesting personal observation. Auto braking?
Looks like that's from constant contact, not braking. Perhaps a V clip brake pad separator is needed, like they do on toyotas, to push the pads apart during brake release. Overall, it looks like a caliper design flaw, honestly. Some camrys have this issue, and nothing you can do but use aftermarket calipers or pop in V clips. It also only affects front rotors for some reason, on toyotas.
Brake pads should be sticked to the caliper. They have a layer of glue on them when new. Of course caliper should not be stuck and pads mounted with v spring.
I have exactly the same brakes on my E400 not hybrid Front pads have a tendency to get stucked by dirt so they either get hot or not braking. The car is so stable that it is not noticed while braking hard maybe at soft braking when it is wet you can feel it. Even the MOT couldn't feel it and he tried everything but nothing helped. I didn't know what it was either so I ordered renovation kitt and renovated the caliber all for nothing. The worst part is I complained to the 2 year authorised service agent and they did nothing as always! So just remove and clean. Sübhanallah I still have the original brakes even the pads after 11.5 years and some 97 000 miles.
My W212 did exactly the same thing. Non OEM brake pads left a residue on the disc and was causing a shudder. I replaced the pads with OEM pads and the shudder went away. I don't understand what's happing.

I'm planning on getting a w115 or a w123, I'm so excited for it. Great videos, this one too!

Deterioriation of Mercedes engineering
great videos kent, is it posable to upgrade the rear brakes for bigger ones? have to wait and see.

Looks like a caliper problem
Brake pads should be sticked to the caliper. They have a layer of glue on them when new. Of course caliper should not be stuck and pads mounted with v spring.
are pistons simultaneously and equally pushing
Inside pistons on the calibers are sticking.
Probably saturated brake fluid that started boiling and created brake pressure without the pedal being pushed
either the caliper is sticking or binding, or you have a left foot braker.
Similar problem on my w205. Slide pin(s) stuck
There is a no slide pin on a multi-piston setup

Upgrade break pad
Perhaps caused by poor pad material choice by akebono.
Maybe swap to another brand of pad and the issue will go away
