I have a 2012 E550. My sister was driving my car and broke down. She had called me and said she heard a loud hiss then a few minutes later the car just stopped moving. Luckily she was in a parking lot. When I went to go check it out I thought my rear brakes had locked up (still might be possible?), but I noticed I was able to drive the car in reverse. It was unable to be pushed in neutral either. In Drive I slowly accelerated and for a sec something felt like it slipped and i moved forward just a little bit before it locked up again. I have an iCarsoft and checked for fault codes in the transmission and nothing came up. The gears shift without a problem and even the paddle shifting worked fine. Based off some research I did I am assuming the hiss was a fluid tube bursting and leaking out transmission fluid. I'm getting the car towed to my house to work on it. I would like more opinions on what you guys think is going on with the car. Thanks.

Update: bolt for rear right caliper had fallen off for some reason and caliper got stuck to wheel.

Get it home and inspect. No one can tell you anything unless you can give us some more info.
