HAPPY NEW YEARS ! 2016
hello fellow GLK owners, I haven't been too active on here but I'm here to update my progress with my GLK, for those wondering what my GLK looks like, its a 2010 GLK350 stocked. I'm currently at around 85K miles. I'm getting my wife a new GS 200t so the GLK will be all mines. nothing major besides the maintenance, I got a tune up @ 75K miles.
I will post up pictures of my GLK very soon !
Did you guys ever heard of the mileage award they have with Mercedes?

What model year is it? Is it a CPO car, does it have an extended warranty? Is it a GLK350 or 250 Bluetec?
My Bluetec gets on average 37-38 on the highway according to the computer but 36-37 calculated mileage at speeds around 70-75. Drive slower and get better MPG.
Make sure no matter who your buying it from you have the complete service history and a Carfax report to document it's history. I know some people don't do all the scheduled maintenance when required.
The 10k mile recommendation is about right but based on your driving style it could be shorter or longer.
My 14GLK bought in April 14 currently has 13K miles on it.

it isn't CPO. it was bought at the dealer @20K MILES in 2012 by the previous owner. no warranty on it what so ever.
BluTec is nice ! i would love a diesel engine, too bad there's none available on craiglist. i checked in a lot of different states, hard to find one that is being resold.

Bought our 2011 GLK new, have about 23K on it now and love it.
Enjoy your GLK and welcome to the forum...
50k is minor service, which is nothing more than an oil change. With lots of highway miles I'd to oil changes every 10-15k miles. You can use blackstone to do oil analysis (25 bucks) and see if there are any bad signs of indication to do more frequent oil changes.
MB recommends coolan flush every 150k miles / 15 years, you might want to do flush more often than that.
Check to make sure transfer case is not leaking, there is TSB for that.
I think GLK will do well, keep us posted.
I'll do all the flushes and an oil change as soon as I get the car. So do flushes about every 50k. I think I'm going to do it in intervals of 12.5K because I drive a lot actually.
How do I check if the transfer case is leaking and what is TSB I'm actually getting the car on Tuesday, I'm going to go on a NY trip when I get it. How much would it cost to even fix a transfer case problem what is a transfer case anyways the transmission ?

Thanks for the warm welcome
Is there any major differences in the years ?

Seems to be common for AWD benzes (not specific for GLK) to develop a TC leak. From what I read it depends on what sealant was used. Dealer quoted $800 to reseal, an indy who know what he is doing can do it for half that. In my case, dealer was making stuff up and the my TC wasn't really leaking. Just something to keep in mind.
GLK (esp 2010-2011) doesn't really have any "new" technology - pretty old engine from E-class and pretty old tranny used on all other benzes for years.
The only major issue I've read is failed tranny in a few cases, but it seems to happen early on (under 40k miles).

One benefit of 2010 is you can put tranny in "Sport" and it doesn't reset every time you restart the car. Also no Eco star/stop and other fuel saving engine killing BS technology.

In regards to the reset. In new GLKs, everything, which is not much, goes to default once the car is restarted. I.e. The tranny is in Comfort by default and goes back to Comfort every time car is restarted (from what I read). On 2010, the tranny is always in the mode that you select. I drive in S, so the tranny is always in S. Why does it matter? In Comfort the tranny starts in 2nd gear (to save fuel), in Sport it starts in 1st.
Btw, the tranny adapts to your driving, and you can control shift points by accelerator input. If you progressively push harder on the accelerator the shift points will raise. If you take it easy it upshifts very quickly. Also, if you double tap accelerator while driving, it will downshift (not always, tho). If you floor the accelerator and then let go, it will hold the RPMs for a few seconds before up shifting and going back to normal.

too bad the GLK is too new doesnt have older models to know if it does well in high mileage. does the GLK uses the same engine as the C class benz?

Most C classes are C300 with 3 liter engines.
What year are you getting? 2010?

That was actually the transfer case in the 4M versions...
