Update 09.4.18
Just got my car back from service
Spent almost 1 month there finally gearbox failure from the 1st time so have to replace a new one and wait for a part to shipped from German
1day before pick up dealer called and told me that expansion tank cracked how come? Before dropped my car off nothing wrong with that part. So need to fixed after wasted for another part from German. Final part came but got another called said the thing that connected from expansion tank crack too. No ETA. Until last Monday I got my car back. While my car at the dealer I told Matt to check tail gate because some time didn t closed by itself. He said everything work find until Sunday I opened tail gate 1st time after I got my car back now I can t closed. So I call Matt today. He said I have to pay for diagnose. Damm. Evertime I took my car to this dealer got new problem happen.
What kind of service is it
So I took my car to the shop outside they say lock is broken. How come before check in not broke. But got car back. Is broken same as expansion tank still ? For me

Service manger told me to bring the car back
When I came 2 weeks ago he told me one thing he said he will take care for me on the problem
Today I came early in the morning then he said I have to pay everything to fix my car

1st I took back car at 96000k still under extended warranty. And at service (Rafael) told me he could hear any thing come back when noise come back, so I asked him I after warranty gone who will take care of my problem , he said he will put note that MB will take care of these problem with no cost after the when my car over 100k. I went back chad said I have to pay surprise!!!!!! Also Rafael no longer work

I bought this car for $51k
15000k got noise
29000k Axle felt down cause me an accident
Afer that change axle 2-3 time
Around 30000k water pump leak
Around 65000 rear gear replace after that keep making noise
70000 driver heated seat burn by itself
Oxygen sensor replace
