New transmission????
I have 2014 E350 4 matic sport, 24940 miles...Car is running absolutely great, no issues until a few days back...With even sligh turn left or right i felt strong vibration on steering, visited dealer and they replaced planetary gear/transfer case/... Picked up car and after 10 miles,same problem even worse...Now dealer open case with MB and looking i am gonna need new transmission... Waiting for dealer call...My warranty expires 8/31/19,and problem like this makes me nervous... I asked master mechanic if replacing parts are improved and he said NO...Any advice??So much for Best or nothing... I was told every 4matic has the same issues,even S class...I love this car but????Are the newer models having the same issues...

Well, you're already heading down this path with the dealer but I'm not sure how the transmission falls into this. Seems that it would have troubles regardless of whether you're turning or not. As I remember power from transmission transmits thru a transfer case to the front wheel halfshafts, and out the back by driveshaft to the rear differential. The transmission doesn't know if the car is going straight or turning.
I guess front hubs and steering rack attachment have been checked by now but if theres vibration at turns, then the question is what is seeing side loading that is overwhelming that part or parts? All suspension is ok?

Thanks,i will post progress... Reading more about this issue,i am surprised how many 4 matic models/from 2006/, regardless being C,E or S class is involved...And inability from company like Mercedes Benz to fix it...

A simple test could reveal this. If you let tire pressure way down on front or rear tires you would generate speed difference between axles that could show the vibration also when driving straight.

A simple trial wiould be to let tire pressures way down on one axle tires to generate speed difference and perhaps wibration then appears driving dead straight too.
