 This is my first Mercedes.  Where do I start with this dangerous and poorly designed car?1. By putting the gear shifts from the center console (in most cars) to the wand, that used to be the windshield wipers, I have actually shifted the car accidentally into Neutral when it started to rain(thinking it was the wipers) while driving on the highway!  Luckily it wasn't Reverse!!!2. In the summer, when I've gotten into the hot car,  I have actually gotten BURN MARKS on my right arm, while placing it on the center console as I was about to select a radio station. They trimmed the console with REAL metal ...it felt like I had put my arm on a hot frypan!3. The dashboard controls for defroster, A/C, temperature control etc. are all exactly in a line and feel the same...there are no indentations or separations. So when you're driving at night and you need the defroster, you can't feel which one it is...and even when you find it, you still HAVE TO TAKE YOUR EYES OFF THE ROAD a second time, to look up at the screen, which is placed to the right of you.... just to make sure you have selected the correct control.4. The driver's seat is not only uncomfortable, but I have been in physical therapy since July 2015 (a few months after I leased the car)  and I am still in P.T. April 2017) because it has caused me nerve pain in my neck and right leg. I have to lift my right leg very high to get  over the threshold as I  get into the car,  and then FALL into the seat and adjust myself. I realized that after the first few months the constant lifting and adjusting have been the cause of the nerve pain.5. The power seat adjustment ( not the memory adjustment) that you generally find in most other cars,when you slip your left hand down along the side of your seat,  to move forward and backward...has been moved to THE DOOR. Wow! I thought it was so clever...BUT this ergonomic design is dangerous! If you want to make a slight adjustment up or back,when you're wearing a thick coat or just want to move back a little, you must remember to do it while the door is closed. If you need to adjust it once the door has been opened, you must REACH OUT BY HOLDING ONTO THE STEERING WHEEL with your right hand and move the seat positions with your outreached left hand. I had the door swing back on my left ankle because I had already put my left foot out of the car...I got a CONTUSION under my skin for months from the door slamming onto my ankle!6. Now we come to the gorgeous center console...the entertainment center (I thought it was beautiful when I was looking at the car in the dealer's showroom). They designed two choices for you. One is a turning dial and the other is a "swipe" selector. Well, that "swipe" method CHANGES MY RADIO SELECTION whenever my handbag or arm slides over it (Example: as I am putting my bag down on the passenger seat). Frustrating and annoying!7. The most concerning issue with this car happened twice... it SURGED as I was pulling up to a vertical parking space in front of a store. I stopped the car inches away from crashing threw the glass window of my pharmacy...I had driven my car onto the sidewalk! That happened in June two months after I got the car.  It happened again in January, as it surged and nearly went up on the sidewalk at the school I volunteer at...both times I managed to apply the brake to stop it.I SPOKE TO THE MERCEDES MANAGEMENT TWICE...once to the service manager after my arm got burned July, the summer of 2015, and about month after that to my Mercedes salesman , about all these issues...I was told the manager would call me...he NEVER CALLED ME.  I want to end my lease, butthe  car salesman felt I had too much time left on my lease. I don't believe I can prove I am in P.T. because of the car's threshold. Has anyone else had any of these issues with this car???UPDATE: September 23, 2016. I was told by my salesman that the Mercedes-Benz manager would call me shortly after I wrote the original review, but in all of these months I've never gotten any contact at all. I guess I've given up calling or talking to them, since I don't think I can prove that I have been in physical therapy since July 2015 because of the seat design and also having to lift my right leg over the threshold ( causing me to literally fall into the driver's seat). That repetitive motion, over the first few months, caused nerve pain from my lower back down to my right knee. All the other issues I listed are the same...I still have problems with all of them and I'm actually afraid of this car !  I am hoping to get rid it when my lease  is closer to 20 months old. I am thinking of several other car brands: maybe BMW or Acura.UPDATE: October 2017. Nothing has really changed, still in physical therapy...EXCEPT I've gotten closer to finishing my lease. HURRAY!! I can hardly wait to get rid of this poorly designed "luxury" car!  LAST UPDATE: April 2018. FINALLY RETURNED THIS MERCEDES!! It was NEVER driver-friendly!!!!
