Does anybody NOT have the 1-2-3 rough shift issue?

i find this staggering for any car never mind luxury. Never heard of such a faff to get a car to change gears normally.

Apparently, it applies only to early production Alabama cars: one man, one pig.
It is repairable, and should be done in warranty unless you want a bill that will scare your donkey.
Geez, it could be worse, e.g., Ford Pinto, the rolling bar b que....

Early production - I bought my c300 last month and it's a 2017 model and having this issue. I hope I won't hear the typical well it's designed to do that. Ha none of my previous non luxury cars did that in the past.

My rough 2nd to 3rd up shift occurs in "Comfort" mode, and only happens when the vehicle is fully warmed up, and I'm crawling in heavy traffic.
As long as I can accelerate from a stop or crawl at a more normal pace (e.g. no one in front of me), I don't feel the rough up shift from 2nd to 3rd.
I dropped my car off yesterday to have my AMG side sill panels installed & a burnt out door handle LED replaced...and I told the service adviser I was still having rough tranny up shifts, and asked them to check for reflashes.

If you are told that's the design spec, someone is pissing on your leg. It can be fixed, but it takes two days, two techs, a laptop and a twenty mile drive.

Which is why mine still is crap because they're not going to do this when they can say 'we can't feel it' or 'it's normal'

Drag your dusty *** to Milton Keynes and demand to see the Head Kraut in Charge. Fault lies with you, now.
Very sorry about Manchester.

C300
Perhaps its your hybrid powertrain. To date, every pure internal combustion 4 cyl turbo Ive driven has this very disconcerting characteristic. I would highly suggest that anyone considering a c200 - c300 give up on the idea immediately. And I suspect dealers are fully aware of this issue and would reset the adaptive TCU and warm up the engine prior to a prospetive customer's test drive both of which will alleviate the issue.

I'm dropping the car off this Friday. I hope the service techs knows what there doing in my neck of the woods and have a credible solution. If they don't I'm gonna ask to see the manager and ask him to bring along his best tech for a spin with their laptop to make all the adjustments. This can be a pending class action lawsuit as its safety issue.

Dude, a spin with the laptop won't do jack. New software written for your car must be loaded, then two dudes and a laptop will tune it.
This condition never creates an error code.
This condition is hated by dealers.
Ya gotta go to the Head Kraut in Charge.
I had to threaten a class action, too, before they let me deal with the HKIC.
Do NOT let mbusa RECORD your calls.

But I like your idea so on Friday I'll bring that up to the service rep about the patch and maybe it will solve the issue. So where's the dealership that did the patch cause these techies have a common database they use to look up issues and solutions.

I have a US 2015 C300 7g 4matic. Had multiple resets and a transmission update, but no cigar. Dealer is now saying "works as designed". C'mon, even a Dogde Dart shifts multitudes better. Wondering if anyone out here that does NOT have that issue? And if so, what year and how many miles driven?

In my c400, i dont have any upshift issues. However, when im coasting down to the light with either no brake or very light pressure on brake, 4-3-2 is rough, especially 3-2 from time to time. Any c400/450 owners feel the same? Or did the update fix it?
and i had a 2016 c300 for a rental when i had my c400 in for some warranty work and that thing had the roughest shifts ever. Downshifts were fine but upshifts were the worst ever. I thought hondas transmissions were rough but this c300 made me change my mind. Im glad my c400 starts in 2nd gear instrad of 1st in c300 as things are more smooth that way.

Not worth the hassle. Life is short. Back to BMW for me, a manufacturer that can design high performance cars without the need for fecking about.
