The Official GLK Problems with Aging Thread
Embarrassing? I guess so. Not for the noise. For the lack of attention paid to a potentially catastrophic, deadly conditon.
This is not neccessarily a fault of the GLK aging. We don't have enough information to diagnose the problem. We do have enough information to STRONGLY advise you to get the problem corrected. As I said earlier, disc brakes do not make noise without there being a problem. Don't list this as a fault of the GLK.

So in summary, when brakes squeal it does not necessarily mean you need brakes.

If what you say is true of ALL German vehicles with disc brakes, we have all been hoodwinked. I repeat, since 1989, as far back as I can recall for certain, I have owned 3 vehicles, driven them a total of 400,000 miles and never ever heard the brakes make any noise at all. The brakes also stopped me as required. Any performance to the contray is unjustified. German brakes included.
ps: There are probably a dozen BMWs of various age and model here at work. I never hear their brakes. I will ask the owners if their brakes make noise.

Softer pads perform better therefore better braking but the downside is noise and very dirty wheels. The noise can be remedied by removing wheels and cleaning the areas as well as applying a particular compound (sorry can't recall name - I think it's lithium grease) on the back side of the pads.

I don't think I pointed to a specific problem. We are all too far away from the vehicle in question to know what the problem is. My point is that the vehicle needs to be inspected by a qualified service shop and the noise eliminated.

Use this instead. The description of the RED DISC BRAKE QUIET bottle says as following, "CRC Disc Brake Quiet is a specially formulated to dampen the vibrations that cause disc brake noise. It forms a water-resistant, high temperate film that will absorb noise and quiet disc braking. Disc Brake Quiet should not be applied to brake lining.
The BLACK CALIPER GREASE bottle says, "A specially formulated synthetic grease containing molybdenum disulfide, graphite, and TELFON. Keeps critical sliding parts in brake calipers free for optimum braking efficieny. Helps to prevent caliper blinding, sticking, vibration and squeal, and provide for even pad wear. Prevents rust and corrosion on brake parts to assure extended safe performance. Extremely high temperature features make certain this lubricant will not melt or run off caliper assemblies, metal backing plates of the disk brake pads, self-adjusters and drum brake systems. DIRECTIONS: When rebuilding, assembling, or installing disc brakes, thoroughly clean or replace all bolts, bushings, holes, pins, inserts and anchors. Lubricate all parts with a light coat of this grease including bolts which mount caliper to vehicle. Apply grease to caliper components with a small brush. Use cautiously to coat the back of your pads if they didn't come with Teflon shims or if the new pad is squealing."
I personally would use Teflon shims or CRC Disc Brake Quiet on the rear of the pads instead of any grease.
Wayne to SA: My brakes make a noise. Fix it.
SA to Wayne: Your M-B brakes make that noise because they are the finest brakes in the world.
Wayne to SA: Stop the brake noise. If not, I will file a Lemon Law Claim.
SA to Wayne: Yes sir, Mr. Wayne. We will stop the noise.

2. Squeaky brakes at 12k. Took 3 and 12 months for a resolution. MB paid for parts, but we paid labour.
3. Front light bulb. Not a surprise at 3 years.
4. Leaking windshield fluid reservoir. Fixed under warranty.
5. Loose trim piece in back. Not resolved.
6. GPS issue. Can't search for a retailer in another town. Comes up alpha order by locale. Try searching Costco. Comes up with Alaska locations first. Told that it is programming error that can't be fixed. What a pain!

rear door power lift has always been a problem. i'm about 50% successful, my wife slightly more.
Otherwise, like the car. the $300 upgrade of the GPS software is ridiculous.
Got a call late Thu saying they found a gasket leak between the transmission/engine. Said it was really small and something they're starting to see more often on GLKs. I had a GLK loaner over the entire weekend and noticed the door sills are not as wide so it's easier to get in/out of the car (also didn't realize they gave me a RWD one until i couldn't make up a slippery hill, lol).
I can pick up the car tonight so i'll report on what was actually replaced. overall i think this is considered a reliable car by Mercedes standards as they've pretty much brushed off everything as a "small inconvinince". lol.
After greasing them and the noises still there.
The dealer replaced both side mirrors.....under warranty.
one transmission replacement but it was under warranty (so not really an age issue)
screw caps from rear hatch have a tendency to fall out.
otherwise the car is doing well... will be bringing her in for Service A next week. Still on original scoprions tires that came with the car. And still in love with the Carneol Red on her
- No serious problems to report.
- At the dealership for regular A, B maintenance.
- Recent transmission flush and fill $$$$.
- Driver's seat cushion replaced under warranty because of crease/crack...I have running boards and think I swing out to clear them but no hassel from dealership.
Overall I would say the GLK is well built in Bremen Germany!
I have had 1 bulb fail replaced under warranty
Other then that had pads done at 42k and regular service.
The one thing i started to hear is a strut or suspension noise
Over bumps but thats prob from driving on NYC roads.
2010 GLK350 4-Matic Loaded
Needed new rear right side marker
Rear LCA bushing
New transmission on order. Tranny developed the whine sound of death. (Transfer-Case Failure) Very upset.
Besides this, MB would better serve it buyers if they improve the handling characteristics of this car IMO
Some Concerns I wish they would address:
1) Steering Feedback is too numb!
2) Turn in needs improvement
3) Larger wheels and offset models requires new steering geometrics to improve self-centering characteristics.
4) Overall suspension is way too soft. Front end plows even with the slightest throttling!
Maybe have variable suspension as a option.
5) Make interior more contemporary, less wood!
6) Raise the freaking Climate Controls for better access, or place them on a new touch screen master controller.
7) Enlarge the outside RV mirrors slightly.
8) Larger brakes/calipers needed.
9) Place pad sensors on all inner pads rather than one side only.
10) Improve rear design to better accept a hitch. HomeRun and pre-wire all the necessary electrical to a rear receptacle for instant hitch hook-up!

My 2010 GLK350 has 42k Miles on it and I've started noticing a "snapping" noise from the rear cargo area over bumps. It's almost like the cargo cover is moving and the plastic makes a noise when the body flexes, but I have removed the cargo cover completely and the noise is still around. I have tried pressing on all the interior panels in the cargo area to see if some of the fittings are lose but it hasn't really solved the problem. This only happens over bumps, on a smooth road there is absolutely no noise.
Anyone else experiencing this noise over bumps from the cargo area interior trim?
