The parking brake is an electronic button. In fact if you switch off the engine and open the door it gets applied automatically.What you can do is apply the HOLD function with your foot brake, no need to switch to neutral, it is absolutely fine to roll up to a red light, come to a hold and apply the HOLD function whilst leaving it in drive. Just touch and go

Yes I know about the hold and opening the door but presumed by previous post that hard pressing pedal in neutral also engaged park brake.

It just did it going up my somewhat steep driveway. I'll report back here once I get this checked out next week. I'm also going to have them check out an issue with my breaks getting stuck at red lights. Almost feels like the parking brake is activating in Drive. This car does not like red lights.

My parking brakes do not auto-activate, although it's done this a few times in Park, it's not consistent. I park uphill on our driveway so I still do the old school place car in neutral before applying parking brake routine. It relieves the strain on the transmission.
The "stuck brake" issue was indeed the HOLD function! I'm not heavy footed, but the function apparently turns on at red lights if I apply just a tad too much brake pedal pressure during complete stop. Good call dejongj. Glad I'll just be showing the service center the hesitation/jerking issue now.

My first M-B was a 94 E320. I was told by my local tire company that the E320 had a "distributor less" ignition system, when they did an annual safety/emissions control inspection done. Unless times have changed I don't think that M-B has gone back to a points, or electronic ignition system using a distributor cap.

Same experience Jerking issue on GLC 43
First of all, thank you to everyone on this forum for helping me decide to buy my glc 43 last month! I've been reading this forum everyday and I love my new car (except for this one issue 
).
It doesn't happen every time but occasionally when I am slowing down for a red light and the light goes green before I stop and I try to accelerate my glc 43 starts jerking until I take my foot off the gas for a few seconds. This is more likely to happen if I have the car in sport or sport + however it has happened even in comfort (I never put it in eco!).
I never had this issue on my glk 350 and my partner doesn't have it on her GLC 300. Does anyone know what this might be? I plan to take it in to Mercedes and ask but I'd rather not go in completely ignorant. Thank you!!!

The car went in for a diagnosis and I was told this is due to the adaptive transmission. They said to drive it for 2000 miles and see if it still happens. I am not buying that. I've never heard of any Benz needing 2000 miles to adapt to driving habits, and even if that were true, why is the default mode violent and dangerous? I'll still let her break in and see if anything changes, but this is not good. It's supposed to be an AMG.

I bought my car in mid December. I've been driving it quite a bit. Picked it up with around 15 miles, and now have nearly 3k on it. Yesterday, for the first time ever, my car did this. I do usually drive in S+, since I think the car feels too sluggish in any mode. This was the first time it did this, and it was jarring. My first thought was something with the transmission, but I'm not sure. I'll be out later today, if it does it again, I'll take it to the dealer.
I don't think this is normal at all.

Did they go out in a test drive with you? Also note there is another post here with someone requiring a new gearbox, may want to check that out.

Mine was doing this, and sometimes would put itself into park which was very dangerous. Then I'd have this acceleration stall as if the fuel was being cut.
Long story short Im getting a new Transmission installed by dealer after sending a transmission oil sample to MB. I bought the car Dec 19th and it's been in the shop for 3 weeks going on 4.

I'm not buying that either. Then again I have done nearly 4.5K miles, perhaps there is something in it. But logically it makes no sense to me.

(and thank them immensely for that)...guessing this is what my dealer is doing too.

Wow so all they did was look at fault codes. I would have thought that if they had it hooked up they can see whether the adaption is complete or not. Sounds like a wasted journey. Sorry to hear that.

Some of the C43 owners (W205) are also experiencing this problem.
https://mbworld.org/forums/c43-amg-c...ack-forth.html
I mentioned this problem in the AMG Private Lounge Community Forum and they asked that I contact my MB dealership and request them to open a service case (so-called "TIPS"). This will notify MB/AMG so can they can further investigate the issue.
Any 43 owner who has experienced this problem should have their local dealership open a TIPS service case.

I'm having the same issue. Picked up my GLC43 about two weeks ago and this happened on the very first turn out of the dealership (was in Sport+). I didn't think much of it at the time but now it has been happening on a regular basis when driving in Sport+, albeit, not every single time. I'm taking it in later this week to try to replicate the issue with a tech in the car but was wondering if anyone got this fixed or know what the potential problem might be.
By the way, I owned a GLA45 and, at one point, a Macan Turbo. I'm used to driving in sport+. This is definitely not a "characteristic" of the car. When it happens it's downright dangerous as the car will violently jerk/buck (not to be mistaken with a hard shift) and has, on more than one occasion, forced to me to switch from sport+ to comfort just to get the car to accelerate properly.

Figured I'd give an update on this.
I brought the car in and drove it with the tech in the car. Was able to replicate the severe jerking/jolting/bucking within 5 minutes. Tech agreed that it's not normal immediately. They did an update of some sort that they thought might fix it. I got the car back. Next day I started having the same problem. It's been a week and I've been able to replicate the issue several times in Sport+. I want to say it's happening less as of this update but that might be me compensating for the onset of the bucking.
Either way... looks like it's going to have to go back in. Super choked. Not only does it make the most fun part of the car unreliable but also dangerous. Confidence in an easy solution is now zero.

I did not. It hasn't done it for a long time, so I've simply forgotten about it. It is warmer out now, maybe it was the weather?
Either way, I beat up on it pretty good, and it has taken it like a champ. No issues. I guess when it gets colder, I'll see if symptoms return.

Just wanted to update this. I'm at almost 5K miles now and the GLC43 still does the scary hesitating/hopping thing and it seems to do it most when there's traffic coming at me fast while I'm trying to make a left turn. Anyway, I'm moving to a place 2 miles from the Benz dealership and will proceed to give them he11 for being such bullshidders.

Hi
My experience is that if you want to use Sport + you need to be in a situation where you are going to nail the throttle and it will work a dream. If your in traffic or situations where your on and off the throttle your going to get this jerk as descried.
Comfort and sport should not have this issue, if that is the case I would be taking it to the dealer.
If it is only sport +.... remember this is setting the car up to go full performance and handle Accordingly.
If you use sport + in the right manner you can avoid this jerky throttle response.
I know your all thinking "but it should not be that way" and I tend to agree.
But it is a personality of Sport + "Go hard or go home"
