This is the 2nd time my 2015 Cls400 Mercedes has been returned to the dealership for this reoccurring problem of the electronic command system totally shutting down while the vehicle is being driven on the street and frwy.navigation blinks on & off, side view mirrors fold in & out while vehicle is being driven, radio turns on & off, electronic braking system activated itself while I was driving on the frwy & around town, keyless entry would not work so I had to use the manual key to get into vehicle & remove push start button to insert the key to start vehicle, windows would not work nor air conditioning & it was a hot day.speedometer would not work & gas meter showed empty even though vehicle had a full tank. Vehicle was simply unsafe to drive.I purchased the vehicle on Dec 24 2014 and the problem started in Aug 2015 in which the dealership had my vehicle for 5-6 days & said they couldn't figure out what was wrong but confirmed my story because the computer system they plugged into confirmed the malfunctions.now sept2015 the car is back at the dealership for the 2nd time for the same reoccurring problems.all I know is the vehicle is unsafe to drive.the vehicle has 10,000 miles on it but was purchased brand new & I am the original owner.
