general problems of the 2011 BMW X5

I was on my way out of town on interstate 94w, when without warning my vehicle started to slow down and I could not accelerate. A sensor displayed stating the vehicle was overheating and to drive moderately. I was in the fast lane and had to get over at a moment's notice even with the vehicle slowing down. The second occurrence was on a busy street with a speed limit of 45 mph, and the car overheated, and stated "engine hot" and it proceeded to shut down. I could not accelerate and was almost hit from behind but the car switched to another lane at the last minute. This car put my life into danger 2 times to many. Something needs to happen before someone dies.

2012 BMW X5 upon engine start up when cold, the engine surges excessively. If the transmission is engaged during the surging (fluctuating rpm) the vehicle lurches forward/reverse causing a dangerous situation and potential accident.
