2014 GLK250
Hi Everyone! Hope all are doing well.
I am a BIG Diesel (Bluetec) lover. I already own a 2014 E250, & have just purchased a 2014 GLK250.
Not a "typical" SUV guy, but maybe for the Winter, it will perform a little better. We will see...
My question is: Does anything seem to go abnormally wrong with the GLK250?
I know, it's a stupid question, since I am already have been driving my 2014 E250 for a long time now.
Just curious if anyone has a "shout out" about something particular.
Thanks much for reading.

Very happy with mine, so far. I wish it had a few more accessories (it's pretty bare bones for a Mercedes) but I had to buy it during the shortage.
When the extended warranty from the AEM expires, I'll probably have the EGR/DPF/DEF removed.

No, it's not my opinion that I'm happy. It is a fact that I am happy. If I said it was the most reliable car in the world, that would be my opinion. (If I said it was the most reliable car I've ever had, that could be a fact, but, truth be told, the jury is still out on that one.)

I am in fact very happy with mine as well. Have owned it for about a year, not had a single issue (61K mileage when purchased). I did get the emissions modifications done, freely, from Mercedes, and am awaiting my free $2600 or $3500 check stemming from the class action settlement. That day will put a smile on my face
The extended emission control warranty covers almost all components that could fail with the emissions system, and goes well beyond that to include "any component that could reasonably be impacted by the effects of the emissions modification." Properly maintained and driven, this engine can can last 200-300K, as they do with the exact same engine in the Mercedes Sprinter commercial trucks. Doing a lot of short-tripping with it is when the emissions issues seem to arise the most.

Just curious...how many miles do you currently have?
I have not received mine yet - probably sometime this week. But I know the engine is extremely respectable. I also currently own a 2014 E250, with 101,000 miles. I purchased it used, with 40,000 miles. It has been perfect. Absolutely no problems. That is why I purchased the GLK250. Same engine!

I would make sure your boost pipes are in good condition, as they tend to rip and let all the boost out while causing a CEL and a P0299 code.
The hoses are around $120 each but stealerships have been known to throw $3k+ turbochargers and $800 wastegate actuators at the cars, without so much as checking the damn hose.
Other than the aforementioned Achilles' heel (overly complex exhaust system), pay attention to the driveline. New fluids in the transfer case, front & rear diffs and transmission will ensure a happy life. Don't forget the torque converter too.
Also, keep an eye on the water pump which is equipped with a plastic impeller that has been known to fail. There is an updated water pump available, and it's worth replacing the drivebelt, pulleys and tensioner at the same time.
What else? Oh, fuel injectors can get sticky and make a little extra clatter sometimes. Use the best fuel you can find and add a quality fuel additive (check out OptiLube or Stanadyne) at every fillup to extend the life of your HPFP and injectors. Replace fuel and engine air filters every 40K miles, cabin filters every 20K miles and oil&filter changes every 10K miles with quality 229.51 or 229.52 spec stuff.
And probably most important: don't baby it. Start it up, drive off gently (don't let it idle needlessly), warm it up properly and then drive the snot out of it. It'll thank you.

I most certainly appreciate your insight. Well written. Lots on information. I have already made a copy to keep.
But, as you might already know, I also own a 2014 E250 Bluetec 4Matic. Currently, just turned 102k. Bought it 40k. The car has been perfect.
ZERO complaints! It is a truly great vehicle. I aways take care of the car. I drive (approximately 15k/year) So I change the (Synthetic) oil & filter
every 7500 miles. Air Fliter every year. Cabin Air Filter also every year. Fuel filter every 2 years. I have also changed the transmission fluid, filter & gasket.
(Although not sure how often to do that)
Having said all of that, one of the reasons I purchased a 2014 GLK is, the Engine (I think) is the same as E250? Which is quite an awesome bit of engineering.
Although I assume the 4Matic on the E250 & the GLK250 is different. I am not sure what to do with that. I just received the GLK250 today from the transporter. Currently has 126k. My "initial" survey was almost perfect. The interior looks like it has 26k, not 126k! Simply perfect. I am blessed.

2014 and 2015 GLK250
As andreigbs stated, I agree on the Stanadyne and use it with every fill-up. I've blown turbocharger hoses on both of mine (one on each side). Had to replace a fuel pump on the 2014 that we purchased used but that's all. The 2015 that I bought new is another story. Practically every component of the emissions system has been replaced - from the DEF pump and heater to the DEF injector (twice) and the diesel particulate filter at 15,000 miles. My guess is that the injector wasn't injecting enough fluid and the DPF clogged. Thankfully, those repairs were covered under warranty. But, there is no other car/SUV that I would rather have. These things really are Great Little Kars.

As previously stated, I own a 2014 E250 4Matic. Have driven it for the last 62,000 miles. (now has 102,000 miles) To say it is perfect, it an understatement. I change the Synthetic oil/oil filter every 7,500 miles, & that keeps everything working as it should. No problems. Yes, I have changed the Air Filter, the Cabin Air Filter & Fuel Filters also. In fact, slightly more often than recommended.
So, I assume the GLK250 will operate similar? It is the same engine. I just purchased the GLK250, as a Winter car. We get snow in NJ, so I wanna be safe if I need to travel in the bad weather. Not even Registered yet. (Appointment is Monday 1/3) Then I will replace the Synthetic oil/oil filter, the Air Filter, the Cabin Air Filter & the Fuel Filter. Then I start at at "clean slate." We will see what happens...

2015 GLK350
I bought a 2014 GLK250 new and loved it for 18k miles until it started having emissions systems problems that were not fixed after repeated trips to the dealer where they kept it for weeks at a time. I traded it for a GLK350. There is good reason for the bluetec class action settlement.

GLK250
I got one! And it's great. Kinda
I have 150,000 kms on mine.
I Think the water pump is a common fail because of plastic parts. Mine is going.($600)
One I test drive and now the one I own has problems with the signal stalk. Signal lights wont activate until restart. ($900)
The emissions have been mentioned but not sure if the heater in the def tank has been. If you live somewhere that gets to -10c it will likely fail eventually. ($1200)
My heated wheel no longer heats. ($4500... I'll buy gloves)
Lane departure errors but that may be related to the signal issue (vibrate is built into that module)
comfort exit lifts the steering wheel up but they always get jammed and the gears fail.
I LOVE the torque and fuel economy. It's cheaper than my fiesta to drive on the highway and it pulls 5000 lbs.
the only upgrade you really want are the Fancy intelligent headlights (brighter, turn with the wheel and an extra cornering light).
Avoid running boards if possible. They just get dirty, are in the way and your calf will always be dirty it wet because of them.

Add me to another new owner... I had a 2014 GLK250 about 4 years and sold it which was a huge mistake... I just found one that is decently equipped with about 48k miles. It was serviced at the dealer so I got the log of repairs etc. It seems pretty solid, now I just have to wait for it to show up...

Bluetecs are obviously not for everyone. The added expense and potential emissions failures may deter most buyers not familiar with modern diesels, and that's OK. These issues are common to more than just MB, and even domestic makes are prone to failures of the complicated emissions systems.
But when they're working right, modern diesels are great to drive. They're economic, powerful, and practical. It is the luck of the draw, but so is life...

Still going strong. I cannot complain much. I had CPO unlimited Warranty till FEB 2022 which saved a lot of $$$$. Now I'm looking into DYI repairs..... I will see.
Just getting P261F code for circulation pump issue and haven't figure it out yet. I could not find much info yet from Googling.
