I understand AMG is supposed to make fast cars but holy ***** at the seats ... ungodly uncomfortable. theres virtually no padding in my car. bottom of the seat as well as the portion for your back.

and I'm still wondering if anyone has been able to use the sun glasses holder because i can't fit anything in it.
Perhaps your body proportions are not the average person but to say 'a Ford takes a dump on an S class' is hilarious.

We have a 2019 ford focus, 2019 F150 and recently got rid of a top end Lincoln continental and they don't hold a candle to an S class.
F150 and focus ride like wagons in comparison to the S550 coupe.

Even my near 20 year old CL55 is much more comfortable.

As for seats, there are multiple seat options to pick from.
You should have test drove a car before buying it and complaining about the seats.

I mean, that's what a test drive is for, to see if you like how it drives and like the comfort levels.

Yep, I love people that buy like an average cla with no options for 29k new and complain "Mercedes sucks". Well its affordable because its pretty much bare bones. Good stuff cost money, why higher end cars cost more money. I can agree the seats are "ok", but theyre definatly not worth complaining about. The ride, everyone is different. I personally hate how some cars or trucks drive very loose and prefer the glc63 or any other car that is tight steering for better control. If op loves ford that much, which completely is the bottom of the barrel rust buckets, idk, Mercedes must have really pissed him off somehow.

It is not the matter of "Power" my friend. My C63s (503 hp) has more power than the GLC63 (469 hp) but that one is mated to a 7-shifter and runs like a dream. I also had a C55 in past and that one ran great too without any problems . I have owned a BMW M6 with 500 hp and no jerking. I also currently own a Maserati GT with similar amount of power and no jerking. This is not about showing off rather giving you a perceptive that many cars with a lot of powers don't jerk and jump like a bronco. The issue is that the there seems to be a real issue with GLC63 and how its 9 speed transmission works, it is not tuned well. This is not a chipped Honda that one should accept this kind of jerking.

I wouldn't go as far as to say Ford is bottom of the barrel rust bucket. My wife and I had a Ford Mondeo wagon diesel as a rental in Germany for two weeks at the beginning of May this year. It was a great car. Lots of useful options like native navigation, Apple car play so we could use navigation from that instead, driver's aids like adaptive cruise and lane assist with speed limits on the dash cluster which was awesome in a foreign country for me. It was also very comfortable and had no problems cruising at 200kmh down the Autobahn.

I also own a Ford Raptor and it's a hell of a nice truck that's super comfy on long trips. Part of the reason we purchased our GLC43 is because I would rather take the truck on road trips than our 2009 Audi A4, but it's just not practical due to size and fuel mileage. So we went shopping for something to replace the Audi. In the end the GLC is what we ended up with. I have no loyalty to any brand. They all make good and bad cars. I just like that we have so many options depending on what's needed, yanno?

I own a GLC63S coupe and have the same problem from 1st to 2nd gear but I think it’s the just the car wanting to unleash the power because there’s so much torque. Asked a Friend and he says it’s normal. So far there’s no new software update on the trans. When I do get heavy-footed from standstill and just slam the gas there’s no problem of this jerkiness.
Macan Turbo was suggested but that’s the car I sold to buy my current baby because my Macan was in the workshop for 3 months due to transmission problems so there u go. It’s a Q5 in a different shell 🤓

2019 AMG GLC 63S+ Coupe
I too have experienced the bucking in my 2019 AMG GLC 63S+ Coupe. Getting my first Service A this weekend and was going to have the dealership take a look. Any more recent updates on this issue? Incredibly surprised that this happens in a MB. My wife drove it once in C and it happened and she thought she broke the dang thing. I mostly drive in S+ for obvious reasons, but its truly freakish when it starts bucking. I'm torn....I certainly don't want to diminish the performance with a flash update but I'm not real crazy (too say the least) about the bucking either.

GLC63S
Probably said in this thread somewhere but this is not really an AMG or Mercedes problem. Multi-clutch transmissions by nature can be jerky at low speeds which can be somewhat mitigated by your driving habits. They are spectacular for power handling & delivering extremely fast shifts both upwards & downwards.

Smooth? Not so much.

It's the primary reason many manufacturers are rushing back to or have stuck with torque converter based automatics. They will never shift as fast or be as efficient but they are a lot smoother especially at low speeds.

As far as Ford's being better than S-Class do a search on PowerShift dual-clutch automatics. Somebody's going to be writing a lot of checks.

I have taken mine in and they said that they can not do anything regarding the shifting of this trans. If there was an up date flash from Mercedes they would be more than happy to re-flash to quell the complaints from the customers. I guess M-B has not had to foot the bill for Lemon Law returns yet. From what I have encounter in this forum is that M-B owners are loyal to a fault. They say things like "you don't step on the gas peddle correctly" or words to that effect. I have owned 4 M-B's over the last 15 years, this is the most unhappy that I have ever been with a car. The little GLA AMG 45 was a pleasure to drive. I loved the way the automatic shifted, there was something satisfying just as ripping off shifts in an old ZF 5 speed trans-axle. This new trans makes me angry every time I pull away from a stop light. The owners in here are blind to the outside world of autos. YES, people Mercedes can make mistakes! But the worse part of all this is that they will not or cannot fix it! A new car in this day and age should not shift this badly.

In S+ my GLE 63S had the problem, my BMW M40I had the problem after an aggressive tune was added and my GLC 63s has it. It seems fine in Sport though, I have never tried comfort mode.

2019 GLC 63
The GLC63 makes over 525 HP - Dyno verified, more than a stock C63. You can see the dyno information on the GLC at Renntech tuning website for the car where they breakdown the numbers very well. My new 2019 does this same jerky **** and I do believe it is one of two things or possibly both:

Transmission temperature not in the white
Adaptation sequence

I've had less issues with this bronco effect once I started warming up my car before driving - similar to what you do in winter. The adaptation sequence can be renewed if you unplug the battery. These cars "learn" your NORMAL driving habits, and if you do something different than what the car learned it will behave goofy.

The Ford dude cracks me up... OMG you cannot compare a crap USA car to a Benz. Any American car by the end of the warranty is literally falling apart. The cars drive like a Benz with 200,000 miles on them. I've owned German engineered cars for a decade (own two Benz - 2018 E300, and 2019 GLC63) nothing USA makes with wheels holds a candle to the Germans. If Benz made a diesel pick-up truck Ford would be in serious trouble.

GLC 63 AMG, Trackhawk, X3M
I’ve been driving the car for about 12k miles. Something I noticed is when in Comfort mode the car is in its most toned down mode. The car will shift through gears (the jerkiness) till I’m at 30mph in 6th gear. Counteracting it would be driving in Sport mode. It is the only mode I drive in at this point.

AMG GLC63S
I've owned my GLC63S for 3 months now, paid a blistering $150k AUD and the car has many engineering issues... Besides the crazy throttle/gearbox sensitivity and short shifting in C mode and shifting points all over the place which I think is more a software issue, the front tires skip when turning sharply at low speeds, harmonics from the drive line at approx 80km/h, wheel vibration at 200km/h, aerodynamic vibration at 230km/h.
It seems MB have thrown this car together with left over parts. I now understand why MB didn't use the 9 speed in the GT and GTR Pro because its a **** gearbox.

Yes the car can jerk violently which isn't right but I find I can minimise it with throttle control in c-mode, s & s+ is a little harder if you're in traffic. I have had the box get stuck between gears (1st & 2nd) when I go to take off. The box doesn't want to start in 2nd gear anymore in c-mode and I can't even force it to start in 2nd in manual mode, good luck if you're in snow.

I've also recently had a tune (engine only) which upped the power 100hp which made the boost more sensitive i.e boost wants to be either full boost or no boost. The power is better now but coming from a 700hp supercharged 6.2ltr the 4ltr wasn't that impressive prior to the tune.

This week I'm getting the box adaptive/relearn or what ever you want to call it to try and help with the shifting points and converter slipping at high speeds. If this doesn't help I'll tune the gearbox with a custom setup. If this doesn't work the car is gone. If it works I will be upgrading the down pipes and cats and tuning to stage 3.

In summary, I regret buying it and regret not buying the Trackhawk (which does have its own problems I know) I wouldn't recommend this car to others.

2019 GLC AMG 63 2018 Jeep Trackhawk
I know how you feel

First off I happy to say I have both sitting in the garage. A GLC 63 and a Trackhawk. I had a GLA 45 AMG with the 7spd trans. It's shifting would put a smile on my every time. I am sorry that I replaced it with the GLC. It never bucked like an old 4 wheel drive truck when looked in 4 wheel. Backing out of a parking place I always have the U joints (constant velocity) hiccuping. The same daily driving where the little GLA gave
me 19 MPG the piggish GLC only is getting 14.2 MPG. I get into the Trackhawk and I smile. The trans shifts perfect the engine does not need a tune to go out and kick butt. The interior is ALL leather, not just
the seating surfaces. The doors and dashboard are leather from top to bottom. The back up proximity warning works and does the front not always the case with the GLC. The warning lights for right lane and left lane are toward the top of the side mirrors and double the size of the GLC which has small mirrors to begin with. I can change the radio from AM to FM to XM with a quick touch. Try that with a GLC. The
cabin of the Trackhawk is actually quieter the GLC where course road noise makes you think you are in a steel drum. Oh the Jeep has a one down side, it is a hog around town (12.4 MPG). On a road course
the GLC will probable do a quicker lap and the trackhawk would blow it away at the drag strip. But guess what I am not going to the race track or the drag strip just going to the grocery store or the airport and just want to have fun along the way.
