Default Active Lane Keeping Assist

This is worst damn "feature" on the vehicle! Works well on my Lexus and Tesla (although I never use it...turned it off), and just terrible on the Sprinter. And I can't shut it off! You have to disable it EVERY TIME YOU DRIVE! WTF? You can turn off the blind spot monitor for good, but you CAN'T turn off Active Lane Keeping Assist and have it stay off. [I know the short-cut to turning it off, but I shouldn't have to do this every. damn. time. I. drive.]


Sprinter slams on the brakes and swerves to the left every time go into a right-hand merge lane to get off an expressway (which we have plenty of in my area). Dashed lines, no cars or traffic (so no blinker), and then HOLY SH$T! What just happened???

Maybe there just aren't enough of these vans out there with ALKA to have a bunch of pissed off drivers...I don't know. But it simply is NOT SAFE. If someone is exiting behind me an I fail to use my blinker, that driver is going to get a big surprise that neither of us want. All I want is to be able to shut it off permanently, but I CAN'T.

Rant over...at least for now!

If there is a "feature" that you feel is a safety issue, you can file a complaint with the NHTSA ... it's how recalls get started...

https://www-odi.nhtsa.dot.gov/VehicleComplaint/

(i'd start by checking with your dealer/MB to find if there's a way to disable it "permanently")
((masking tape over the camera??))

In my Mazda, lane keeping assist was a pleasure to use. Just a little tweaking and it would be as nice as a self-driving car.

The Mercedes implementation of it seems to come from the idea that if you wander out of your lane you must be dozing off and need to be simultaneously startled awake and punished.

I like the warning, but I don't like the technique of using braking to steer the vehicle. It's bad enough that I'm confident it will be changed.

Sounds like difference between German and Japanese cultures. 😎

Yeah...I have experimented with it and the only time it really does the hard brake scary thing is when I cross a solid line. The happens only when I cross the solid line of the left, like swerving to avoid a car leaving it's lane coming into me, or when I go to exit the freeway and accidentally cross the corner of the solid right line, exiting slightly before I should. Only one has it happened outside these scenarios and this is the really scary one; Construction had left a solid white line diagnally across the current lane markings. The van thought it was the right solid lane line and when bats#@t crazy. Almost all of the time, the system works as intended. It's that .1% that scares you.

Not a fan either
Confirms why I did not want active cruise or lane warning when I was trying to place a custom order
Couldn't get an order placed so bought one off of a dealer lot and settled with it having these features
Do not like them either

The active cruise is awesome. I really love it. What is your complaint with it?

Agreed, it's an incredible safety and convenience feature and a much better implementation than in some cars I've driven.

On a long trip, I figured out that the LEDs around the speedometer indicate the set speed, and if a car is within 450 feet ahead of you, in your lane, it indicates that car's speed as you approach it. If you end up in stop and go traffic, it has a long delay when traffic starts moving. If you hit RESUME it will start moving immediately, as long as the car in front of you is moving.

LDA Option is incredibly dangerous.
In addition to painted lines and compromised evasive actions issues, I recently was startled when my Sprinter braked back and forth due to etched out lines when interstate construction crews move lines back and forth. ...just for etched out lines.
I could not find any LDA complaints for Sprinted at NHSTA. I filed my NHSTA complaint. Note - NHSTA has all the MB models to chose except Sprinter. I manually keyed in Sprinter after Mercedes 2019.
I also notified my employer State Farm and my Subrogation management to track recovery opportunities against MB design flaw
The more that NHSTA and our carriers hear from us, the more likely MB will 'expedite' a fix for this?
