Rear axle steering and eABC are among the two best options I purchased on my 2020 S580 car. It makes a huge difference compared to my 2020 S560. The rear wheel steering allows for nice, tight turning on corners and parking (not too noticeable at speed).

Last week I got a message that “The maximum steering angle of the rear axle steering is restricted. Turning radius increased”. The car had been parked overnight and there were no visible restrictions. By the time I got it to the dealer a few days later, the problem had resolved itself. Dealer is not aware of this as an issue.

Has anyone else experienced this?

One other issue: Occasionally when I put the car in gear, F or R, the emergency brake sticks for a split second with a loud sound as it releases. Dealer says it’s normal.

Has anyone experience this issue?

Didn't the workshop read fault codes after the rear axle steering issue? If there is a message for the driver, the car would certainly have a fault code saved.

Had the car been washed or driven in rain when the emergency brake gave the loud sound? The brake pads may have been glued by water/rust to the brake disk.

On the first issue, they claim there was no code. But, took photos of the screen both during the fault and without the fault, now.

On the second issue, yes, more noticeable after raining, but does happen from time to time. Dealer suggested it is pretty “normal”.

Got a similar message once when the vehicle was going thru the auto car wash's track/ guide rails. Haven' seen it since. Were you up against a curb?

No, car was just parked over night and I started the car.

hi...can i suggest this test, with engine on...and have someone standing outside the car to observe the rear wheels:

leave it in park, then try to turn steering wheel fully in either direction.
leave it in neutral, then try to turn steering wheel fully in either direction.

now try to do the same, but with car in drive, with foot on brake.
do the same, but in reverse, with foot on brake.

if i'm not mistaken, i believe the rear wheels will only engage in steering when in drive or reverse, but not in park or neutral.
and when u try to rotate the steering wheel all the way into either direction in either park or neutral, the message you posted in the photo is what appears.

run this test and let us know what you experience.
good luck!

I will try it, thank you.

You are correct, the rear wheels wont move unless in R or D. I tried to see how it worked when they delivered my car the other day and the wheels dont go anywhere unless in R or D

I am seeing the same on my 21 S580 with the 10 degree steering. Also see starter battery drain frequently and have more software issues than I can list. Mirrors randomly go up, won’t come down, window won’t roll up/stay up. Overall least reliable of the 8 s classes I have had.

I was glad to hear that you liked the E-ABC. I ordered my 580 with it which should arrive in a week. There are some that posted they thought the car drove worse with EABC. Some felt that it made bumps more perceivable which would be the total opposite why you would spec it!!

as i know , the rear axle only works in drive and reverse. it does not work in park and neutral.

yea theyre right , its pretty normal , the emergency brake makes a weird sound. all of the mercedes and other vehicles got this problem.
