Car is booked in for an inspection next Friday, in advance of that I thought I would check to see if anyone else has experienced this. I'll feed back next week after (hopefully) it is fixed.

For a couple months now, the car (6,600 miles on the clock) has been suffering progressively worsening judder under braking. Most notable when braking from high speed, but always there.
At first it was only acute enough for me, the driver to notice. I could feel feedback through the brake pedal and steering wheel of a rhythmic judder. Over time it's worsened to where passengers can tell and it feel like the whole car judders under braking.

I'd convinced myself it was somethng to do with my winter tyres, but having swapped back to the originals this past weekend, it clearly isn't. I had a brake inspection done when swapping back and nothing was seen.

I'm hoping it's not something I caused by changing wheels and tyres and will be a warranty claim!

Brief update.

They've had the car for the day and the service manager, when he called me, quoted the mechanic: "it's horrible".

They need to replace the rear brakes and whilst they have them in stock, as its a consumable, they have to perform a list of comprehensive checks before Mercedes will authorise the warranty repair. So I'll be driving this god awful e-class coupe thing all weekend. Actually, I think I'll steal the wife's Qashqai.

It won't make you feel any better, but I thought I'd add Red Ken is a 2016 220d Sport on 18" wheels shod with all-season tyres and I've never experienced any judder whatsoever under any braking condition in the 12000 miles travelled so far.

Off topic, but since you're the threadstarter, what is it that you find so awful about the E-Class Coupe? I saw a white one with the Night Package and dual 12.3" screen option and it certainly had immediate kerb appeal for me. A 220d 4MATIC Coupe must surely give a similar but slightly more driver-focussed experience to your GLC.

Thanks - I'm hoping there was no damage done when the winters were fitted that will land me a costly bill.....


The Coupe I have is not a car that suits me at all. The kids love it, they think it looks sporty. I think it looks like a try-hard Panda with it's white paint and blacked out windows and roof. The wife went in it once and said [the dark interior and general lack of light] felt claustrophobic and made her feel car sick she wont go in it again.

My issues with it:
- AMG trim brings run flats, firm seats and rock hard suspension which combine to an awful straight line driving experience at any speed. I know I'm getting older (44) but why would anyone pay for that experience!!
- the Garmin sat nav is horrendous! Literally a 2 second delay responding to every key press and (no joke) about 4 minutes from pressing "go" to the screen coming back with a route.
- cabin noise is intrusive - seems to be a combo of the run flats and the pillar-less doors
- rear window is so small it's like looking thru a letterbox from across the street
- I am fairly tall (188cm) but even with the seat down v low the rake of the windscreen and the size and proximity of the rear view mirrow fully blocks 1/4 of the front view.
- no 360 degree camera combined with the small rear window and small rear passenger windows makes reversing difficult.
- I feel like a total knob when I step out of it in public. It screams "middle aged wanna be sports car driver"

On the positive side:
- it goes around corners at speed quite wonderfully

I have my GLC back - replete with 4 new sets of disks and pads replaced under warranty.

They have no idea what caused it. It's something they've seen before on a GLC.

I'd hate to think what that solution would have cost had you been out of warranty! There's a lot to be said for replacing a car before the end of the warranty period, especially if you own one of the more prestige marques.

Thanks for the very complete list of justifications as to why you couldn't live with an E-Class Coupe. I'm only half an inch shorter than you and at 60, I've been indulging in the mid-life crisis for some 20 years with a TVR, motorbikes, custom pick-up truck amongst others. I've got to admit the whole AMG Line ethos was the exact opposite of what I was looking for when I optioned Red Ken. Comfort was my priority so that meant Sport trim, Air Body Control and sensible diameter rims. I think it would now be very hard to accept any vehicle that falls below this benchmark so I guess it won't be the steroidal Panda if I stick with Mercedes.
