What?! A brand new Mercedes with 89 miles on it and it needs a new Transmission? I do not think I have ever heard anything like that before! I've got a gas version coming in a week or two and if that happens to me I can assure you I will not be as gracious as you've been with either Mercedes or towards the dealer "sticking up" for you.

Michelle77, your issue is simple.
Have the MB/dealer KEEP that vehicle, and give you another one, same options, and a loaner to drive till they can make perfect tender.

michelle77

Thanks!! They are going to deliver my car to me so I won't see the old one. Out of curiosity though, why do you want to see the old one?

michelle77

I have a feeling MB hasn't heard of it either since they are airfreighting a new one and have asked the dealer to return mine to their research center. The reason I'm not asking for another one is because I waited 10 weeks for the exact car I wanted. Don't want to wait that long for another one. At this point, all I can do is follow the lemon laws which means that I have to give them 3 opportunities to make it right. I'm thrilled to have the whole unit replaced rather than trying to tear it all apart to replaces pieces of it. Based on a lot of what I've been reading on these forums, I really didn't expect MB to do this, so I feel encouraged that they are trying to make it right. I'll keep you posted and thanks to everyone for your comments!!

Thanks. They have given me a new ML to drive while they replace the transmission. Don't want to wait another 10 weeks for another one. Guess my tastes in options is a little out of the ordinary as they couldn't find me one that I wanted before so I had to special order. I'll keep you posted!! Praying this was a fluke and that the next transmission will work!! There just isn't any other car that I want and I've looked at them all!

michelle77

Don't forget that it is a mechanical device run by computers. Cars are surely different now than when I was a kid!!

michelle77

Got my car back yesterday with new transmission!! Drove back thru the area where I had failure to "break the spell". So far so good! I now have 232 miles on it....here's hoping for 132,000 some day!!

Katiesdad7, just wondering how your BT is doing these days.

katiesdad7

I really only drive it on the weekends and it still bucks down the street when cold. Now cold here in Florida is about 80 degrees. Its very evident when first starting out. The bucking doesn't really bother me much but I am concerned about possible damage being done to the transmission.

I'll be sending the Lemon Law paperwork in this week or next and see what MB has to say. I don't know if I have any chance but its worth the cost of the stamp.

...My wife and I think so - because that's exactly what our ML350 BlueTEC does when accelerating at low speeds (0-30 mph). Unfortunately, our service department has turned a deaf ear to the problem - they can't hear anything at all.

I suppose we could be wrong about the source of the sound - has anyone else had a problem like this?

...Also, our fuel consumption seems a bit odd. According to the vehicle we get 10 mpg around town and 40 mpg on the highway. Generally, there's very little in between - it's usually either 10 mpg or 40 mpg.

I am happy with my gas 350

Have had our BT now for about 3 weeks and put only 700 miles on it, combined city and highway. No issues (yet). Smooth, no hesitation, and runs very quietly. We're in Charlotte, and it has been quite warm here, so I will keep an eye on things as the weather changes and the miles rack up.

my 2012 ml350 bluetech have hesitation and bucking at the start from the day one. they never fixed it or even not acknowledged this problem. Now giving me complete system failiure. happened three times. stuck up in mall, work place and home garrage. nothing will work at this time. first time mb road service took to dealership and they said it is a computer glitch and fixed, but it happened next day morning again and next day again. now it is in the dealership waiting for the fate. i think it was a bad decision getting this suv. Your opinion please. what can I do.

listerone

All I can say is that my Bluetec has been pretty solid so far.I get some bucking when it's cold for a few minutes but nothing approaching your problems.With luck they'll fix it for good this time.Don't throw in the towel just yet.

katiesdad7

My experience with MB is that they won't acknowledge any problem. Especially one they can't fix. On one hand I fell sorry for the dealer because they know its a problem but have their hands tied. On the other hand I think they are snakes because they know of the issue and won't admit it.

I have found that with MB its all about the money. MB won't pay the dealer to fix something that can't be fixed so the dealer doesn't spend any time on it. Without a computer fault code the techs don't do anything. Gone are the day's of actually troubleshooting a problem. Its all about the computer. Now if the computer is bad, as it is in the hesitation problem, then nothing gets fixed.

Send in the lemon law paperwork and force them to fix it.

Starlifter

hows things going these days. did you submit the paperwork(lemon law) i only nosticed the hesitation once since the beginning of summer. now that falll is coming(ny) i anticipate this becoming an issue again. i'm sure i'll be at the dealer by oct

katiesdad7

It still bucks all the way down the street. I'm going to wait till it gets colder. I think that since it doesn't happen to all the diesels then it can be fixed. Its just that since the computer doesn't tell them what is wrong they don't go any further in trying to fix the problem. Seems the computer controls everything they do. Its very easy to duplicate and the dealer and rep have seen and felt it happen. They just don't do anything about it.

Has anyone actually had the bucking fixed? Mine started doing it when its cold this week.... what is weird is there is nothing new with the weather since the time I took delivery... It bucks pretty hard.

dougiebear

My 2013 has yet to buck. Damn cold lately too. Tranny shifts at higher revs when cold but no bucking.

ciparis

My 2013 has never demonstrated the least bit of hesitation (I came from a 2011 E350 Bluetec, and I'm pretty sensitive to anything not being quite right). Sometimes if feels positively clairvoyant: "time to go? OK!".

My 2012 BlueTEC had a mild hesitation when cold, and I had given up complaining about it. Then, at my 10K service, I mentioned that I was experiencing a noticeable downshift when coming to a stop (normal, but annoying). The dealer installed updated transmission control unit software. The downshift is still there, but another effect was to raise the shift points during the first mile or so when the engine is cold (again normal, but the new TCU tune seems to have raised the shift points even more and extended the duration of this cold-engine mode).

The hesitation is now gone--at least in mild SW FL.

Note: The dealer will not check the TCU SW status automatically. Only if you complain about something are they authorized to check the system for updates.

Hey guys, Is the bucking issue only on the BT, anyone with a gas ML experiencing this?

hutch300

I have a blutec, I think its the diesels

ciparis

And it seems to be only the 2012 diesels, or at least most noticeable there. I haven't heard of a '13 doing it yet.

Cyber GS

Thanks for the responses
