 I have had nothing but issues from the moment I leased this car. I can start with it almost locking my 2 year old daughter inside the car, mind you it was in the summer where it reaches 95 degrees on an average day here in south Florida. It locked up on its own with the keys inside sitting in the front seat along with my purse, cell phone and house keys, I was just about to place my daughter in her carseat when this happened. Mercedes charged me $150 on the spot to get it open. It had "malfunctioned" they told me. The gas cap door gets stuck not allowing you to open it to put gas in. I had to drive to the dealership with no gas to get them to open it. The sensors on the cars are faulty and will go off with noone else in the road, they said "yea that's a thing they do."  Forget about brining a large item home in the trunk, the car will not drive with the trunk tied open, nor will it drive if the door is not closed all the way, but will allow my 2 year old to open the car door from the inside while driving!!! There are no safety features to notify you of a car in a lane next to you and it has plenty of blindspots. There are many days when the car would brake on it's own stopping short in traffic and me almost getting rear ended on several occasions. It is currently in the shop now because the cylinder in the engine has gone bad, and will need to replace the engine. The car hasn't even reached it's second birthday. They are telling me that it is due to "bad gas" from the gas station and I will have to go through my insurance and sue the gas station, because it is not covered under the warranty. The list goes on and on, but I would highly recommend not leasing or purchasing this car. I am so thankful that it is just a lease and I am out of the nightmare in a year.
