Picked up new Glk250 3 weeks ago. The AdBlue and Engine light on after first refill. My car and 2 other unlucky new owners cars from my dealer are sitting at dealer waiting for a fix. Was informed yesterday from dealer that fix would not come from MB before the end of the month (software glitches???). It sounds like a number of others on this site are also experiencing the same problems...with no known fix.

Unfortunately, having a new car in the shop for month is not my idea of the kind of car or company that I want to develop a continuing relationship with. I am starting the paperwork to declare the GLK250 a LEMON!!!!!!!

How is it that "almost the same car in 2013" has good reviews? What happened to so drastically change the car reliability?

It seems that MB can roll out new cars by the thousands...but not take ownership/properly service those cars that have already been sold.
I plan to start another search for 2014 (non-MB) car. I was hesitant (but hopeful) when I bought the GLK250...turns out MB does not provide the kind of support that I thought...especially when paying $50,000+.

I don't recall many 2013 owners on here complaining about the adblue warning, something must have changed (Quality check or component change). . or perhaps 2013 owners have a surprise warning coming soon also (its about this time the weather is shifting from 2013 release times)

I believe that glitch is software. It's not truly a mechanical nor electrical problem. I've got almost 4000 miles on my 2013 Us spec, and haven't had a minutes problem with anything. It's basically the same as the 2014.

One of the other threads on the subject indicated a fix coming from Germany that was software. I just wonder if you continued driving it if you'd be able to start the engine when the warning hit the limit.

I think its too early to say, especially for those of us who have 4 seasons. How the adblue sensor reacts to temperature shifts. Particularly in the north east snow

Bob338

If it is software as I believe, or even electrical, I can't see how seasonal temperatures would have any effect. Present reports are all mild weather ones.

There have been reports posted on forums, likely this one, where a fix came from Germany in 2 or 3 days. In that short a time it can't be anything but software.

2013 owner with close to 8000km. No such problems on mine. Keeping my fingers crossed since its been reliable so far. My diesel BMW does have DEF warning glitches from time to time, but seems to fix itself every time.

No problems either here on a 2013 Canadian spec .... going on 27,000 km this week.

2014 us spec with 4800 miles, problem free so far in NY

The DEF/AdBlue problem appears to only be on 2014 model GLK250. So 2013 performance posts are not relevant. But nice to know you have no other problems.

2014 glk250 less then 1000 miles check engine light 8 starts to empty not happy

Can the owners of 2014 GLK250s experiencing this problem please post your production dates?

Mine is being built this week and I'm really hoping they fixed it by now.

Not sure if there are any moderators out there but is it possible to combine this and the pre-existing thread on the same topic?

Duplicate message posted on another thread....

UPDATE -

I received the new car experience survey after purchasing the 2014 GLK250. I documented the problems with check engine light and Ad Blue, remaining starts on the survey (sent to me by e-mail) and finally got a follow-up call from MB survey team. The survey team had a MB case worker call me to discuss the problem.

The case worker called up my information so she could understand the situation. She said she had never heard of the problem and that other case workers that she is working with were also not familiar with the problem. Apparently, the issue has not be elevated to a status where case workers are informed about issues like ours!

She reitterated that a fix could not be expected before the end of the month (earliest!). She also said that if any of you are experiencing the same problem that I have, you should contact the case work number at 1-800-367-6372 (her extension is 6328) - but other case workers can also take your calls.

The issues with the new cars need to be documented at the case worker level so the issues get addressed and they can look/identify the significance of the issue. I urge all of you to call. Unfortunately - the squeaky wheel gets the grease". I hate having to take so much time in order to get problems addressed. . I will be happy to say good things (hopefully) later...but not being able to drive your own new car for 4 weeks...but having to pay for it ....is not my idea of a great service and car experience.

2014 GLK 250 Blutec only a month old and 650 miles. Check engine light came on last night. Will Adblue message be next? Has anyone encountering this problem had it resolved?

17K now on my GLK250 and only a few minor issues.

Had a shifting issue, hanging gears etc.. they reset the programming on my last service and since then its been flawless.

Only issue I am fighting them on is the brakes. At 17K they sqeek a lot. First it was only early morning but lately its all the time... they tried explaining to me that its the kind of brakes exclusive to MB, but its BS... my Acura's and Fords previous never made a sound until they were almost done.

There is some truth in what they say. Basically the conventional way to stop squeal is to put anti-squeal paste between caliper piston and back of brake pad. I am sure that would have been done.

But I just did that twice to my E-Class after installing new pads and rotors. Noise goes away, but is soon back.

What has changed, is that the newer OE (and some aftermarket) rotors have a zinc coating. My theory is that as the coating wears off, it builds up on pads and you now have something different than we used to have. My pads, after a few weeks use, now have a metallic silver sheen. Never saw that in past. They only squeal at low speeds. It is a little annoying, but nothing to worry about.

bop11

When the pads wear out change to Centric or Akebono Ceramic Pads and Centric High Carbon rotors. Eliminates the squeal and the brake dust and the center of the rotor will not rust. On my 350 GLK my front rotors actually wore out before my front pads at 38,000 miles Originals always intermittently squealed. Problem gone. Cost ~$200 for the front axel. Time 1 hour, spline drive for the caliper bolts and a big hammer to unseat the old disk.

Our 2014 GLK Blutec has been in shop all week after cel and 2 days later Adblue warning. Only 700 miles and 1 month old. Dealer says new software update came and then an update to the new software came a couple of days ago. Long list of tests and test drive(s) needed. We are still waiting.

We had ours in for service after we smelled fire / smoke smell and then check engine light came on. Car was only 2 weeks old. 2 weeks later it is back to dealer because check engine light on again. First time was emission and this time sounds like same thing. Dealer said they are calling MB. It is wife's car and she is afraid of lemon! Car runs great. Ft. Myers dealer(Sonic) is being very nice.

I just picked up my 2014 GLK Blutec. It came straight off the boat from Germany. We'll see whether MB has addressed the issue in the latest cars on the line.
