Considering the GLC is such a massive hit in Australia and number of problems now creeping in after ownership, I would like to start a thread dedicated to Aussie-based GLC owners to consolidate our issues and problems as well as what the dealers or MB Australia are doing to solve.

With this, I hope we can all pool together our experiences and or expertise to get MB Australia to solve these problems and issues.

I have a GLC 43 and currently have two active issues:

1) Wheel juddering at full lock which the dealership has claim it is normal and part of the car's characteristics. So far, tyres seem ok in terms of wear and tear. Trying to solve the more annoying 2) before I confront this again.

2) Consistent and regular high pitch brake squeals when braking to stop whilst moving forward. This usually happens after the car/brakes have warmed up (eg. 10-15 minutes into the drive) and will be present throughout the drive from then onwards.

Again, dealership wanted to paint this as normal and even showed me the Owner's Manual stating that AMG High Performance brakes whilst braking may lead to noise. However, the manual shown was a C63 Owner's Manual and my car's Owner's Manual does not mention anything about this. Additionally, the brakes on both cars are significantly different - C63 being High Performance Brakes and GLC43 being Sports Brakes. I have also previously owned another AMG model and have no issues with the brakes.

Currently waiting to bring the car in again and have the brakes removed to be cleaned. Service is currently refusing to do brake and rotor warranty replacement stating that even if they do this, the squeals will still occur.

Hope to hear from Aussie owners if they face any of above or other issues.

I'm trying to see if we can get the protest page to take all GLC owners into considerations rather than just the UK

Madmoau has already registered. My advice would be that you need a bigger sample and more people coming forward from Australia if you want to bring this to the foreground.

I'd also suggest to get your geometry checked. Teckno from the Australia group had that done early on. It is unconfirmed for the UK model but there may be something in it as well.

madmoau

Yes, I agree. Hence, started this thread to, hopefully, get more Aussie owners onboard. There is another local Aussie forum that Aussies use but the conversation there tends to be more about purchasing GLCs.

I suspect the issues we face are more on a global scale rather than just locally.

My brake squealing issues were all sorted out during the first service.
I have the standard (non AMG) brakes which squealed badly in reverse and a little when coming to a stop in normal driving conditions. The dealer replaced the pads with a version that has an angle on the leading and trailing edge of the pad and I have not had any brake squeal in the last month since the service.

Brake squeals seem to getting a tad higher in pitch levels. Waiting till next MB appointment to try get this fix..

I purchased a GLC 250D back in oct 2016 and since purchase the car i started have problems after the 2000km mark.

from 2000km - There was a rattle coming from the engine and i started to encounter squeaking brakes ( AUX BELT TENSIONER WAS REPLACED)

from 6000km Warning light came on took it to mercedes - (WIRING HARNESS TO THE OXYGEN SENSOR/ EXHAUST SENSOR REPLACED

From 9,000km warning light on again. dealership confirms that there was a problem with the car.
DEALERSHIP RESPONSE: service manager and they have advised that the following has been done to your vehicle whilst in our care:
· Changed the upstream and downstream knock sensors in the exhaust to new modified units
· Changed the forward and rear exhaust regeneration wiring looms to new modified units
· Made other enhancements to the area around the wiring loom to ensure no further issue



Seriously we have had nothing but issues with this car and we at the stage of taking action. Has anyone encountered these problems are similar. I believe we bought a lemon and the dealer will not replace our car. HELP!

I have a glc43 with the tyre skipping issue.

Has anyone actually managed to get it fixed?

wmc021

Yes My GLC43 is fixed, refer to

It's a long thread but it will give you all the insight into what you need to know.

Just for the record. Since purchase in April 2016 and some 40,000kms later, can confirm no warranty issues. Of course there are a couple of niggles such as occasional squeaking brakes and wipe judder. But they are minor and it's probably the price to pay when buying the first release of a completely redesign model. I understand the mid life update is due late 2019.

Wheel rim changed from 20in to 19in wheel and to MO non RFT. Also wheel alignment done by specialists. The problem isn't completely resolved. Occurs sometimes on cold wet mornings on my 250d.

My 43 has only done 7500kms and the wear on the front tyres is atrocious. Im down to the first tyre wear indicators, which according to the Continental website, means ive chewed through 50%-60% of the tyre. And they have both literally chewed, the grating marks on the tyre are obvious. Mine crabs on full lock, and i believe this is to blame for the tyre wear as the tyre is dragged across the bitumen. I consider myself a careful driver, this car for the most part is my daily driver to and from work, It doesnt get driven hard at all. I keep tyre pressure at 38psi all around. The back tyres dont have the same wear rate as the front. Still have plenty of tread on the back. I'm going to have to take it up with MB, because a car that cost over 100K shouldnt need tyres in the first year of ownership. The crabbing issue can be quite dangerous whilst parking in underground parking lots with concrete pillars. When pulling in close to a pillar, the car has 'slipped' on full lock towards the pillar. Lucky i wasnt too close or else i would have hit the concrete pillar for sure.. Now the cooler / wetter weather is approaching, i'll have a better chance at demonstrating the issue to the dealer.

The other gripe i have about this car is the inability to fully lift the wiper blades without them interfering with the bonnet. What a dumb idea from MB. I understand that they have to be in the 'upper sweep' position in order to lift them, but other people dont necessary know this, as i found out when i came back to my car last week to find a pamphlet under the wiper blade. I knew straight away that they would have had to lift the blade to put the pamphlet under, and sure enough they scratched the edge of the bonnet by trying to lift the blade whilst it was in the parked position.. bloody pisses me off.. Ive got a nice black mark on the edge of the bonnet now.. Bloody annoying!

Hi tiger_x,

Hmmm this does appear excessive. Definitely not representative of every GLC. Techno, who posts regularly here (and also the Oz Whirlpool/Automotive forum)has noted improvement after getting wheel alignments done. He had a number of them done on his 2 GLCs and noted that over time the factory recommendations have 'relaxed' from the first specifications. Those grated or chamfered edges of the tyre should not occur. Suggest you push hard with your dealer to get a wheel alignment and some compensation for some new front tyres.

I have noted on my GLC250 Petrol, that the outer edges of the front tyres take the most wear. The recommended (on door placard) pressure of 32 psi, is a joke, as that lead to outer edges (inside and outside) of all tyres showing more wear than centre tread. I am now running 36-37 psi. This seems to have flattened out the wear to a more even spread across the tyre. Also now have the tyres rotated every 10K. First rotation was at 10K, front to back swap. Wear pattern now showing a bit more outer edge wear on the left side, so the next rotation at 20K will be cross-wise, front to back and left to right.


OK noted, issue with lifting the windscreen wipers. Yeah we know, not to do it
...but those folk who want to put pamphlets under the wipers!!! Arrrhhhhh!! never thought of that scenario.
Only way to avoid is to position wipers in vertical position when parking in public car parks ......a major PITA.

Hi all,

I've picked up a brand new Mercedes-Benz from a Volkswagon Golf in October 2017. I wish I had found these threads sooner! The high pitched, head turning embarrassing noise happens when the brake is applied. Both in drive or reverse gear. As squealing like this is usually a sign of worn down brake pads, our first instinct was that this needs to get fixed now and how the hell can a brand new car have worn out brake pads?

I have brought back the car for service 3 times in the first 3 months of ownership and got fed up with the a few issues until now.
1st service: They could not make the squealing noise happen and could not see a defect of any kind and decided to warranty replace the rear brake pads.
2nd service: The same happened as I had told them the noise had returned and is just as bad as it was when we first noticed it, front brake pads were replaced.
3rd service: Noise is still reoccurring and the drivers side console window controls had started popping out of the door and rendering them useless. These were "replaced" and the brakes were checked AGAIN with no issues..

I have now booked a 4th service for 17th May 2018 to address the irritating and very embarrassing high pitched brake squeal that comes from the car PLUS the passenger side window switch has also decided to pop out and needs to be fixed as well.

Last part of my rant: I have not yet put in a formal complaint but it sounds like those who do in Australia don't get listened to anyway. Is there any recommendations or class action anyone wants to start? I'm willing to ad to the numbers!
I had owned a Kia Rio, Mitsubishi Lancer and Volkswagon Golf prior to this car and have had zero quality issues because hey you get what you pay for right? So it would seem.. However I went up from a $30k car to a $80k plus car and I have had nothing but issues! Gee.. at least the badge hasn't fallen off.. Maybe they don't care so much about their low-mid range cars since we must not be paying them enough.. If i could turn back the clock I would've stuck with my good ol Golf and saved both hassles and money!

The crabbing issue is unfortunate but not entirely unexpected. Other SUVs such as Porsche also have the same issue. It stems from having permanent AWD in a RHD compact design and the rim/ tyre combination. Interesting vehicles with on-demand AWD such as the Q5 and X3 don't appear to have the crabbing issue.

Found MB Aust had a dont care attitude.
Fortunately, my local tyre retailer provided a partial solution by changing to 19" MO tyres, which substantially reduced the issue on my $80k 250d. Apparently, 18" or 17" tyres would be better still.

incidentally, due to the poor behaviour of MB Aust I did not proceed with ordering a $183k GLC 63s.

So is RWD GLC immune to the crabbing issue?

Ian of Sydney

Just a quick update. The wiper judder issue no more, since replacing the windscreen. The new windscreen was supplied and fitted by MB.

After reading some reviews in this forum and other UK forums, I truly believe this is a design flaw. My GLC 43 AMG was bought a year ago (production date: 03/05/2017). I did not drive too much and only near 5,000 km when it was serviced this Thursday. The juddering sensation was found frequently especially when the weather in Sydney was getting cold. On Thursday, my vehicle was kept in the dealer when I was told that they need to get an advice from Germany, so I agreed with that and waited to get the response. On the next day, I was told to collect the vehicle. I insisted that I need to drive with the technician sitting beside to see whether this issue is resolved or not. However, this juddering issue was still existing (one service adviser told me the problem was fixed on the phone). The technician used the word "characteristic" to explain the issue and promised that it would not trigger any safety issue at all. He also said that this issue was because of the different setting in AMG model and the front wheel was not vertical, which is all considered as normal and very widespread. I was not happy with his explanation and requested to get it fixed. The dealer agreed to give me an update next Tuesday. I don't know if other owners are still having the same issues as my 4 wheel alignment has done, but it did not fix this issue. They might be changing my wheel from 21 to 19 but I don't know yet.

I will post the update next week if I hear something back from the dealer. Please let me know if anyone is in Sydney and also has the same situation.

Hi Teckno,

Thanks for letting me know. I have also seen your posts in whirlpool. For those who have tyres replaced, will tyres be worn out very quickly? I really wonder if 2018 Model will have the same issue. Yesterday, I just realized that my 4 tyres pressure have all been adjusted to 300 kPa as
I saw someone saying high tyre pressure could somehow remediate this issue.
