After 6 weeks at the dealership we picked up our car on November 1st with the updated software. We have had the car back for 5 days and after only a couple hundred miles the engine light came on today followed by the 10 start Bluetec warning. It appears MB has not fixed the problem with the "new" software and apparently they don't have a clue as to what is wrong! As this is the forth time it gone back to the dealer it qualifies as a lemon and I think we are going to ask for our money back and buy something else.

That is NOT good news!

Conbar1943,

I am truly sorry to hear of your repeated problems with your 2014 GLK250. I can only imagine your frustration.

I recently ordered a GLK250 and as you might imagine, I am VERY concerned regarding the repeated issues you and others have experienced with your new 2014 GLK250's. Others on this forum are in the same boat having ordered the vehicle and are awaiting delivery.

Should we experience the same problems you've had after delivery of our GLK's we'd all like to have the ability to take some empirical data to our various MB dealerships and/or forward this data to Consumer Reports. The latter will assuredly investigate, especially given the fact they've previously recommended the GLK350 in their April annual auto review issue.

In view of the above, I ask that everybody that's experienced problems with the 2014 GLK250 ADBlue and Check Engine caution lights please post your build date and delivery dates on this forum. As I mentioned in an earlier post, I don't want to buy a problem. Rest assured, Mercedes will fix this problem if the proper pressure is applied.

Best Regards,
Jim

I believe the problem in the car is minor, though major to an owner who can use his car. I posted early on to the effect that it can only be one of two things, a batch of defective sensors, or a software glitch. One poster on this or another forum posted that in his case they changed two NOX sensors and did a software update and his problem was over. Can't imagine why they would change the NOX sensors, but the one in the tank monitoring the DEF tank would be a great candidate to change.

I prefer to believe the problem is compounded by poor diagnostics and lousy technicians.

I called my dealership and spoke to the sales manager from whom I bought mine. They have not heard of the problem. He estimates they have sold about 40 GLK250's and not one problem of this nature. They are one of three stores owned by the same group and he tells me that they haven't had the complaint in any of the shops. I don't know how many cars were sold out of the other stores.

The build date might lead to the right batch of defective sensors that I would bet is the problem.

I don't believe you are buying a problem. Too many of these around. I'm also sure M-B is already addressing it, witness the recent software updates. A competent diagnostician is the answer should the problem arise.

40 is a lot for the 2014 model - the only model having this problem. Maybe they were including 2013s?

My dealer is small. Not too many 2014 GLK250s delivered yet. They have one car with the problem so far. However MBCanada are, I am told, more than aware of the problem as quite a number of 2014 GLK250s have been sold in major centres and apparently some are/were sitting at dealers awaiting the fix.

It would be good if everyone who has had this problem would post back and let us know if the fix worked on their particular car. It would also be good if those who have NOT had the Adblue problem on their 2014 GLK250 would post.

One could deal with a false positive check engine light; you just keep driving the car until they come up with the fix. A false positive AdBlue check that renders the car useless after the next 10 starts? Plan those 10 starts carefully!

I checked through this thread and found 13 instances of the Adlue error:

wshang 09/11 fixed 09/11
ttrsh 09/29 failed and fixed 3 times
kalenbek 10/02
conbar1943 10/04 6 weeks at dealer, then failed again
Tom Kelsey 10/14 fixed
Lolagirl 10/15
mcinenly2 10/17
mtl20 10/19
fdny136 10/24 fixed 11/01
arminquickert 10/24
xcowdoc 10/26
emtskibum 11/01
se7enspeed 11/05

May not be totally accurate. Would be nice to hear from those who were fixed and those showing no fix yet.

107123210,

Thanks for compiling a list of those with the GLK250 ADBlue and Check Engine caution light problems. Thirteen or more instances of the same problem is not what anybody could describe as an "isolated case."

Has anybody that currently owns a GLK250 and is experiencing these problems pointed MB-USA and/or MB-Canada at this thread? Has there been a problem with any of the 2013 GLK250's?

This thread is VERY bad publicity for MB, and it's not going to remain a secret for long. Somebody that's currently facing this problem might make a call and/or e-mail MB-Canada and/or MB-USA corporate HQ and let them know this has become a BIG topic of discussion on a very popular MB forum. The more that call and e-mail, the better. Link them to this thread. For very selfish reasons it's time to light a fire under their a**. This is in a word, UNSAT.

Best Regards,
Jim

I posted a poll if you all would like to use it to compile.

I'm NOT having this problem with a 2013, but I can't recommend the 2014 GLK 250 to friends or associates until this is resolved.

Fcch,

Nice job sir and good on you! It'll be interesting to see the results.

No problems (yet). *Knock knock on the wood*

Received my 2014 250 last week from the dealer. ~240miles now. Tank half way full, not refilled yet. Production date was around week 38 (mid Sep). US spec and dealer in LA area. Will post updates, if anything occurs.

I have not posted to poll yet, because so few miles behind.

While I do not have one of these (2014 GLK 250), I almost did, and when deciding between two similar GLK's, one gas, and one deisel it was all the information shared here that drove me to the gas model. Make no mistake, this didn't send me running to the hills, and I would consider one in the future, it just weighed into my decision (seems like it could be the tip of an iceberg type situation). Thanks to all posting their challenges, take a tiny bit of comfort knowing you helped make a new father's (who needs his car in his driveway running 100%, not at a dealer or broken) decision a bit easier

On another note, I hope that MB figures this out for you all, and that they provide some level of assistance. This seems like a VERY quick way to lose a lot of customers (that currently own or are considering) if handled poorly.

Picking up our new GLK250 on Wednesday, I am praying to the diesel gods right now.

I got my car back a week ago after a week at the dealer. I have put 200 miles on it and started it many times. No problems-So far! We head out on a 2000 mile trip in about a week and a half. I am kind of nervous about taking this car. It is our only car though. Anybody besides Conbar had a recurrence of the problem?

BigBoeing

Xcowdoc,

Thank you for your report. It's greatly appreciated. Can you please describe how your problem manifested itself and how your dealer maintenance folks responded? Did your dealer acknowledge there have been system-wide issues with the 2014 GLK250 ADBlue and CHECK ENGINE caution lights? Did they describe any formal MB fix for this problem?

I'm in the same boat as koalatm and balticgreen....and will be taking delivery on a 2014.

Thanks Again,
Jim

Jim,

Our GLK Blutec showed a CEL on a Saturday evening. We were leaving town on the following Monday. Thanks to this forum, I knew what would probably happen. We decided to leave town early on that Monday and stop at the dealer on the way out of town to see what they said about the cel. Sure enough on the way to the dealer the dreaded adblue 10 starts remaining message appeared. We called the service department which was now open. They said to come on in. I relayed to them what had been discussed on this forum. Ours was their first one to do this. They gave us a loaner and we went on our way. They finally finished the repair on Friday afternoon and we picked it up on Saturday. By this time, they had 3 more in the shop showing the same problem. If there are 6 or 7 on this forum that have had this problem, there must be dozens out there with or about to have the same problem. We really like the car, but MB better get their stuff together. I am not sure what triggers the lemon law in our state, but I will be very unhappy if ours breaks down on our 2000 mile trip in 10 days.

800 miles on mine with nothing yet...

Has anyone with this issue tried doing a hard reset on their ECU? I'd be curious to see if this gets rid of the 10 restart issue.

(by hard reset I mean just disconnecting the negative battery terminal, or pulling the fuse for the ECU).

Swalroth

We had a similar issue with our 2013 glk 250. It began withe the cel coming on at around 3200 miles. Stopped at a dealer on Saturday and he said it's ok to drive , bring it in next week. On Sunday the adblue countdown began. We dropped it off Monday, had a loaner for two days. They changed a nox sensor and updated software. We got it back on a Tuesday and it's been two weeks without the light coming back on. I'm keeping my fingers crossed on this. I had read bout this issue with the 2014's and was surprised to see it on my 13. Will keep you posted. If anyone is interested I can scan and post the repair receipt.

Bob338

I'd be VERY interested!

bugelrex

urrgghh something to look forward to, I have a glk250 2013 with 1,200 miles..

You have to remember, in Europe, Diesels make up most or half of sales so having these adblue problems must be a nightmare for MB

Alex Bel

In Germany I did not see too many GLKs on the roads and the price is not entry level luxury - 40K EUR + 19% VAT tax, so I am not sure it's a nightmare there because of low volume.
My 2014 GLK250 has only 1,100 miles and I am not happy to read about these problems before our 2,500 miles trip in a few weeks.

BigBoeing

Thanks very much xcowdoc. Did the service department indicate "We have a problem (with the GLK250)" during your interface with them?

Best Regards,
Jim

xcowdoc

BigBoeing ;
I have not spoken to the dealer since picking up the car. We have put over 300 miles on it since. I think it is too early for my dealer to know much about how the fix is going to work since ours was their first one. We leave on a 2000 mile trip next week. That will be the first major test for our car. I certainly hope we do not breakdown especially since we plan to be home just a couple of days before Thanksgiving. I am encouraged that the forum has been very quiet since the new software fix has been available other than the one individual whose car broke down after the fix. Time will tell if the fix worked. We really like our car otherwise. Best of luck with yours.
Regards,
Bob
