Screeching Brakes on the GLC
My dealer complied with the revised LI dated Dec. 22nd on January 2nd and they replaced the pads. Our brakes squealed the very next time we backed out of the garage, the very same day we got the car back.
My dealer just contacted MB USA and was told last week that there was no updated ETA for when they got parts from Germany.
The simple, but difficult, question is, should I?
How prevalent is this Brake Screeching issue? Does anyone know?

I would strongly urge you to hold off until this known problem is remedied for good.
Put another way, I've purchased 6 brand new cars and have never needed to contact an attorney before.
No car is perfect, and all cars will have issues that spring up from time to time. But this issue is known by the manufacturer and they cannot seem to remedy it.

The GLC feels more solid, quicker, with less roll and bounce, and more quality. European feel, more like my previous 328i Sportwagen.
I did have a nightmare car once: a new '99 SAAB 9-6. She was beautiful. Fast, smooth, quiet, handled well. It blew three ECUs in the first year, went through many airbag sensors and headlights, need two batteries (can you say voltage regulation problem?), had to be towed five times, and then needed all pads AND rotors replaced at my expense after less than 20K miles. SAAB somehow managed to beat the lemon laws on it through technicalities.

Brakes have squealed a couple of times but it is an annoyance at this stage. I fully expect MB to come up with a solution and I'm willing to give them a chance. Don't let the churn on a forum thread like prevent you from at least looking hard at the GLC. I love this car.
On the invoice it also said the following:
FOUND NEW COMPOUND BRAKE PADS LI42.10-R-065628 FRONT AND LI42.10-P-P065058 REAR
ORDERED NEW UPDATED COMPOUND FRONT AND REAR BRAKE PADS BUT ARE ON BACK ORDER AT THIS TIME. WILL CALL CUSTOMER WHEN THEY ARRIVE.

So, essentially not much has changed. If your dealer is quoting time estimates for parts, they are not being truthful in my opinion. They are being hopeful. Having followed this for 4 months I have noticed some dealers will say "no eta, waiting for parts" and others will say "by the end of the month" or "within a couple of weeks". I believe the dealers saying "no eta" are the honest ones.
The only thing that resolves this is to contact an attorney and force MB to buy your car back. I'm not in love with any car to where I would keep it with a known issue.
Simply stated, MB has kept selling a model with a known defect: cold brakes start squealing loudly with between 2,000 and 8,000 miles on vehicle when reversing at slow speed.
1) MB has issued new part#'s for both the front and rear pads
a) on the new/new front pads it is the same part# as the new pads on technical bulletin in December - but the "new/new" front pads have a different 2-digit suffix. In the Mercedes system the "new" pads show in delaer inventory - about 575 sets across the US - but these are the new pads/Dec bulletin - which do not correct the problem - and not the new/new pads
b) on the new rear pads - there are a different part# than the original pads - there are "some" new rear brake pads in dealer inventory - although it is not yet confirmed that the "new" rears will solve the problem on the rear - or if MB will need to go new/new like the front pad scenario
On the fronts - Mercedes has to changeover to a different brake pad vendor and a different front brake pad compound to solve the front problem.
On the rear - Mercedes has to confirm that the "new" rear from existing supplier will help rears - or if they need to changeover to new/new.
At this moment - frankly - this will require much more patience to wait for the correct/confirmed MB solution.
Now - if it was me - yes, might consider Centric Posi-Quiet Ceramic - or their Semi-Metallic front pads to see if this solves the issue.
I will work to arrange test fitting on a customers car in the next week or so - and see what might happen..
Keep the beat !




000-420-81-00-64, And What is this?
This is what they ordered (on back order) as a FIX!
I've had this problem for 3 seasons now (on my C300), reported it each year, various fixes were tried, but no solution. It's maddening, and quite stunning that, in all this time, MB can't make brakes that don't squeal like a stuck pig.
