While driving at normal street speed "collision prevention assist inoperative" displayed and car would not accelerate. I was in traffic, but was able to exit and pull over and park, turned car off, & back on. Display reset and car normal. Took to dealership immediately-repair was "non connecting pins". Too early to tell if this solves. Upon investigation, this is a common issue with 2014 mb and I want to document this extremely dangerous performance.

Inoperative pre safe fucntions limited. Vehicle loses power and becomes inoperative without any issue. This has happened multiple times when the vehicle was in motion. It is a potential accident risk of getting rear ended. The vehicle loses power as soon as the message appears and does not give enough time to pull over especially when going on highway with lots of cars and hardly any gap to pull over shoulder. This has happened on a clear straight road and on highways at 55-60 miles an hour. I am submitting the date of latest occurrence of the incident in this report.

Purchased a mercedes cla 250c, and have had it became inoperative while driving on the beltway in washington d.c. Traffic, and more recently on the I-5 in san diego on 1/21/2017 during rain at speeds of 60+ MPH in heavy traffic. The vehicle decelerated quickly and lost speed. The console popped up flashing message 'pre-safe functions limited' on the console. The vehicle did not respond to accelerator. After coasting to the right shoulder I was hit, by a passing car, and the motorist kept on going.this had happened about 10 time, and I bought the vehicle new. Mercedes aware, yet they would not do anything because they said if the engine light is not on we cant diagnose it.
