So the other day I was driving on the highway in the left lane when all of a sudden my engine decides to cutoff on me. No throttle available car just started coasting. Error message on the driver screen said something about consult user manual or something like that. Didn’t have time to read it as I was trying to avoid getting rear ended by trucks. Fortunately I was able to cross lanes in time to pull over into a bus stop. Turned car off and on and everything went back to normal. This could of gone a lot worse I was lucky not to have caused an accident. Did a search and found someone that had a similar issue which the dealer told them turned out to be a faulty fuel pump relay. Taking the car to the dealer on Sat but was just curious if anyone else had this issue and what it turned it to be. Hoping to have some info I can share with Mercedes in case the Tech has no clue where to start looking. Thanks all. My car is a 2014 CLA 250 4 Matic with only 22K miles on it.
