BMW F10 Vibration Defect

I have no issues with my 13 550ix.... drives great no vibration at any speed below 135 mph.... ( havent been faster than that yet ) hope you get it resolved....

Also no issues... 30,000km on using oem rft but for the last 2k switched to the 19 perreli rft on oem rims also with no issues

I have had a different SUV my wife drives with an uncorrectable wobble for 5 months. The tire shop took the tires back after replacement with same brand several times and the new brand worked flawless.

As a side note, 10 years ago had a Pontiac grand am, that when ever it came to a stop, there was this horrible grinding noise... Sounded like metal contact with brake discs. After 2 years of Messiaen around, I replaced the Goodyear HP model tires with another good year model and the grinding went away. Later we discovered the oem tires had some design element in the rubber near where the rim contact area and when the tires aged it would sag and rub against this design pattern in the rubber and make what sounded like a grinding noise... At that point gm paid me back for the new tires as I was able to prove it was a defect...

My point is, tires can play a big role despite the best efforts of the dealer...

update- Took a drive with BMW service tech for a good hour, also compared my car to a brand new 550I. New 550 had no vibrations, it felt so much better than mine.

BMW service tech was a little confused it seemed, at first he thought that I was talking about road vibrations, once I explained to him then he didn't say anything. I think he felt it also but didn't want to admit to anything.

They kept my car for a day to compare to the 550 we drove, they even took the wheels off of it and tried it on my car with no change. Now they are saying that they can replace wheel bearings.

I am so sick of this, I just want BMW to step up and take this car off my hands. This is the 5th time my car has been back in for the vibration issue. Not to mention the loose seat and the faulty camera which they haven't fixed yet.
