My dealer just called me that this work order doesn't apply to my vehicle's VIN. But mine is also 2015. I'm just wondering if US and Canada have different VIN??

ningster

if your dealer tells you it's from the adblue then i think it's time to find another dealer....

chrissk

Yup, I'm calling them again to get this done. Let's see what happens. This thump is so annoying!

1. Would love a wooden steering wheel, our other three MB's have them, way better feel IMO

2. Service notifications are a PITA to reset. Need to research on YouTube every time for an hour.

3. Fog lights. Would help in the mountains some late nights.

1. Wind noise from roof rack.
2. Body roll in turns.
3. Gas mileage.

zarken, I was wondering if you took your car to the dealer for this clunking problem after stopping. I took mine 2 weeks ago, and they performed the drive shaft and bushing lube, and an update to the software but the problem was not resolved. I am taking it back on Monday( feb 8) and will see what they will do next. It is concerning me for the same reasons you mentioned. Is this an indication of problems to come after the warranty will expire?

My wife an I bought our daughter a 2011 GLK350. For her birthday this year I told we would fix the broken stuff on her car. My vote for things I don't like about the GLK would be the lousy seats, torn/ripped after a few years. The command knob stopped working. Both are DIY fixes but the material was sub par IMO. FYI, the fixes were just a few hundred bucks each thanks to contributors to the mbworld forums. Last item in my top three would be the wheels. She has the sportier upgrade wheel but it drives me nuts that somebody designs a wheel that is even or sticks out further than the tire.

After 9 months of ownership. My 3 complaints are
nothing
nothing
nothing

Cwdawson

Lets see...

#1 Can't drive through an entire tank of fuel without having to stop for a break/Lunch/Dinner.

#2 I don't know the gas station attendents name anymore, usually they've gotten a new job by the time I return.

#3 Lack of things to complain about, sure we had the 10 starts left (fixed the same day) but nothing after that.... mind you we've only had it 2 1/2 years....

And lastly I'm thinking it took me 30 years to convince my wife to try a diesel and I don't think I'll live long enough to get her to switch back....

Hello, I purchased CPO 2013 GLK250 3 weeks back and have the same thumping sound coming from the rear. I am wondering how many of you were able to fix it and what was the final solution? Does it cause any long term issues?
Thanks,

H42

1. excessive wind noise due to slight slant of windshield
2. windshield chips easier when hit by rock, again due to windshield angle. they don't bounce off as easy like my other car.
3. hard to drive with windows down due to air pressure causing ear popping

This is something to be aware of. When changing lanes, you cannot rely on left side mirror. There IS a large blind spot. Not being that flexible these days, I find it quite hard to turn head enough to check for a car in the blind spot area. As a result, hesitant to make lane changes until I am sure there is no car nearby.

I have not tried those stick on mirrors. Or is there a total replacement mirror that would work better?

LesF

Huh? If you adjust your side view mirrors correctly, meaning you shouldn't be able to see the side of your own car, approaching vehicles are visible. Now if you check your rear view and can't see a vehicle because of the rear pillars yes there is a blind spot.

The blind spot assist is just that, an assist, it should not be relied upon as infallible as cars that are speeding past you approach faster than the blind spot assist can react.

I have the driver assistance package with active assist and it responds but doesn't replace my mirrors.

107123210

There are many "solutions" that attempt to solve the blind spot problem that most car driver side mirrors seem to have. So presumably many, like me and Mercedes Benz believe that there IS a blind spot regardless of how the mirror is adjusted. But, like you, I don't want an electronic solution.
The SAE do say to adjust mirrors as outlined in this link. I will try it on GLK, but when there are bikes on back or we are towing a trailer, the rear view mirror has marginal usefulness and we need the side mirrors to be looking back, not off to the side.

I've got a 2015 GLK250 BlueTec that has a rear end thump about 5 to 10 sec after stopping (feels like the GLK was rear-ended).

I took into dealer mid-Dec, 2015. They kept car for over 2 weeks. They said they'd never heard of this problem. They consulted with MB techs in Germany who said that they'd never heard of it before. (This isn't true since there are many earlier posts here, so someone is being misleading.) They packed rear transmission with special grease and returned it to me the 1st week of Jan 2016.

The thump was gone but it gradually returned over a 1 to 2 month period. I took it back again in June, 2016. They said there is no fix and software cannot fix problem and that it is normal (get used to it). Right.

I bought a thump-less car, and I'd like to keep it that way. I too hope it doesn't lead to a greater, more expensive problem down the road.

I might try the LI27.19-P-56898 suggestion, but I don't know if this is the same fix as they've tried, but may be worth another return visit.

It sounds as though it may be a part of the suspension that gets stuck in one spot and then lets go. Sway bar, stabilizer bar, shocks. spring, etc. Or even brakes.

Perhaps the dealer lubed these parts and then they dried out again?

I would have them check out and lube all rubber bushings with Wurth HHS-2000 / HHS-K Penetrating High Temperature Lubricant or MB equivalent. And check the up down movement of the rear end to make sure nothing is catching.

Doesn't sound serious, but worth getting to bottom of. May be worth having separate thread on this.

Mine does this to some extent, and I always figured it was the hill-start assist control or whatever kicking in.

By that, I mean that if you come to a stop and release the brakes right away, you will roll forward a bit, or backwards a bit if you are on a very steep incline (unless you activate the hold function, but this is not what I'm talking about).

But, after a few seconds of being stationary, if you release the brakes, they will maintain some grip and prevent you from rolling backwards, and sure enough, if you just feather the gas to drive forward, you can feel some resistance for very very short time (like 0.5 seconds).

That, I think, is the hill-start-brake-assist thing doing its thing.

I suspect the thump has to do with AWD engaging after coming to a stop, and preparing to provide you with more grip off the line.

We've had that same thump and in my own testing if I floor the GLK *before* the thump, there is a good amount of wheel spin, where-as after, it hooks up... so this is my theory.

Pro Se GLK

Just took delivery of a demo 2015 GLK250 BlueTEC with 14,000 miles. It has this annoying thump after a full stop, yes, count to 7 and it will be heard. The first time I noticed it, I thought I had been rear ended. Have read all through this forum about the same complaint. My dealership "has never heard of this issue", but acknowledged the thump. They also told me the bulletin fix posted by Ningster does not apply to my VIN and engine number. They are "guessing" this is a normal sound. I am not convinced. Has anyone else been able to get this annoying thump resolved? I cannot help but think this may be doing serious damage to transmission (or something else) over time.

I'm having this issue as well. Brought it in today and they are replacing a clutch solenoid. Will see how it goes.

Pro Se GLK

tuffcalc - I had the thump fixed - at least for now. Took the GLK back a 2nd time for the service bulletin LI27.19-P-056898. At first they said my software was up to date and there was nothing to be done. Also said my vehicle didn't qualify for anything else on the service bulletin. I insisted they do the lubricating of the gear box also mentioned on this service bulletin. They did the lubrication- only to shut me up - and guess what? It worked. Seriously surprised them! I've been driving the car for almost a week and the thump is gone. Hope this helps with your situation - please give an update.

tuffcalc

Didn't work. Took the car and it started thumping almost immediately. Even better, they rear-ended my car somewhere so the bumper is scuffed and the tow hook cap is missing. Of course they didn't mention it and I only noticed it when I got home.

Will send it back Monday for the thump and the nice bumper gift they left me.

Hugo L.

I would go completely ballistic.

Pro Se GLK

...and I thought I had problems. I got my car back (without thump) but they completely scratched up one of the chrome inserts in my trunk area while topping up the DEF. At least it wasn't rear-ended. tuffcalc - make sure you give them the service bulletin number as they will not do that service by simply plugging in your VIN number. My dealer didn't even know what to look for!

tuffcalc

Got a message from my SA stating they are peforming a "driveshaft lube". Gave them them the bulletin number, so not sure if it is related (hopefully). Fingers crossed this fixes it.
