Tell me 3 things that you DON'T like about your GLK250
(I plan to start shopping near the end of July!)
Thanks!
So far, that's it...but I'll check back in tomorrow PM if I find any more issues as we are taking a 7 hr road trip tomorrow
for my daughter's graduation ceremonies.
Not a dislike, but I am not sure if I understand the engine. I get the ECO mode, it is similar to my Prius. I have never had a car where the brake pedal sometimes comes up to meet your foot, it re-adjusts. The car also seems to downshift/ when driving downhill - maybe I want to coast. It does not do these things all the time so when and why is the question. I know the car is heavy so maybe a safety feature.
The acceleration seems a little weird sometimes. Jerky, not smooth, at odd times. It seems fine on the highway, but odd at lower speeds, 30 mph.
I only have 450 miles on the car, and will be taking a trip this week, so I will learn more. Gas mpg seems lousy so far

It has fuel economy rivaling some hybrids, it emits very low emissions, and it is a Benz. I cross shopped Cadillac SRX and Jeep Grand Cherokee Overland, but fell in love with the GLK250.
With proper maintenance, the diesel should easily go 300,000 + miles without major repairs.
Dislikes:
#1: Momentary turbo lag from a stop. Once it gets going, its pretty quick for a 4 cylinder, I forget it’s a diesel. Lots of lovely torque. Also I keep it in eco mode, switching to sport helps some.
#2: No spare tire. Has run flats instead. I bought a good used Mercedes rim and tire for $100, and will put in back (strapped down of course) for long trips. I also will use it for 5,000 mile tire rotations.
#3: Having to add DEF every 10,000 miles. Can be had at Autozone or Oreillys for around $6 a gallon. Very easy to fill, just like windshield washer fluid, located under the cargo panel in the back.
I know you said 3 dislikes, but I have a very important 4th dislike.
#4: Having to be aware of where I park it, so it doesn’t get a door ding or scratch. I love the classical unashamed boxy look of it.

I'd scratch #3. You have to fill your washer tank too so that's just part of life.
Sometimes when going to drive from park, it jerks real hard. Sometimes, it doesn't and is very smooth.
Anyone else?
As of right now the only negative I can see is that it is smaller than my previous Ford Edge which I knew before buying. Just packed the back with my golf gear for the morning and it barely fits my bag sideways. I can maybe do 2 bags without having to put down the seats, and my Edge took 4 easily....
BUT....
It's an MB, smooth, solid build and so far I have 420 on the trip and over half a tank left
Are you always using the same key (if not keyless)? The keys are personalized and the car learns your driving habits versus those of your spouse's. (long shot guess)

I'll call the dealer.
This has also happened in Reverse.
Does not seem to happen if I press the ECO button and take it off.
I had a Prius and am quite used to the kill of the gas motor, and it seemed quicker on acceleration from a dead stop.
Car seems to drive like a dream at most other times.
1. rear cargo space not as competitive at other vehicles in its class. Presumably they will make it larger with the next Gen with the GLA coming soon a slot below.
2. lack of spare tire/runflats. I really think this is an engineering issue as they could probably have made the DEF tank to accomodate a tire. I also got the Harmon Kardon, and the amplifier cuts into space as well. in addition, as much as 19 inch rims look sweet, probably not as durable as a thicker tire. I will be getting snow tires for the winter, probably X-ice 2s or 3s, and have already bought a fix a flat/pump set and have stored it within the removable trim in the back deep to the netted cubby on the left.
3. windshield wipers seem really sub-par for a luxury vehicle. they streak and squeak easily with mild-moderate precipitation. Only with a downpour do they not do this.
4. I actually wish the transmission would downshift earlier to keep the RPMs around 2k. I end up using the shift paddles in eco mode to shift earlier to keep in that 1500-2000RPM range for better fuel efficiency. If I am going to drive sport, I just change from E to S.

I paid 700 for Xpel Ultimate self healing film/car bra placed on front bumper, hood, fenders, side mirrors, door handle cups, and door edges. Not perfect, but puts your mind at a little ease with the random rock, car door, or grocery cart!
Drive it harder and it will stop hesitating.
The learning can be re-set at any time if you wish to re-train the throttle.
Here is something I copied from a previous post in these forums:
1. Turn the ignition key to the "on" position which is just before you crank the engine to start.
2. Press the accelerator to the floor and hold for 5 seconds.
3. Then turn the key to the off position but do not remove the key, then release the accelerator.
4. Wait at least 2 minutes, the ECU is then reset.
The ECU reset procedure only erases the adaptive transmission and throttle settings. It does not erase any of the fuel, timing or other programming.
Are there separate memories for two drivers based on which "key" is used? My wife has a "spirited" driving style also. But I have a much more relaxed style. My wife's Honda seems to adjust to our different driving styles fairly quickly (in about 20 to 30 miles), but it does not keep separate memories based on which key is used. (This is only my opinion/observation, not based on any ECU programming knowledge.)
If you and your wife drive very differently try a Sprint Booster. It electronically overrides the GLK computer to make the throttle linear and more responsive. The newer ones allow you to set it by push button to three different settings.
This allows it to be stock for the wife and responsive for you at the touch of a button.

1) Brake dust seems excessive compared to what I am used to
2) Maintenance seems expensive, but I get that you have to pay to play
3) Bigger rims + lower profile tires = certain curb rash from the wife, and probably me too

For whatever it's worth if we didn't get the killer deal we got on the 350 we were getting a 250.

1. Reflections of outside air vents in both side view mirrors (just a little distracting, but I'll get used to it.)
2. Automatic door locks sound harsh when locking during acceleration-sounds less than premium. (I know I could disable, but it's a function that I like to have.)
3. Back-up camera only available in an expensive package. It should be standard in all MB SUVs.
