2016 MERCEDES-BENZ S550 4MATIC

IN 2015 MERCEDES BOUGHT BACK MY 2014 S550 DUE TO THE REASONS STATED HERE.THEY ALSO HELPED ME BUY A 2016 S,WHICH CAME IN AROUND 12/18/2015 FIGURED THE PROBLEMS WOULD HAVE BEEN FIXED BY THEN.MERCEDES HAD ENOUGH TIME TO FIX THEM IF THEY WANTED TO SINCE I HAVE BEEN COMPLAINING SINCE I FIRST GOT MY 2014.I IMMEDIATELY COMPLAINED, WHEN MY 2016 CAME IN ABOUT THE SAME ISSUES AS MY 2014 HEAD.THE DISTRONIC PLUS.YOU CHOOSE THE DISTANCE YOU WANT TO KEEP FROM THE CAR IN FRONT. ONCE THAT DISTANCE IS SET, IT DOES NOT KEEP THAT DISTANCE.THE CAR THINKS 200 FEET IS 90 FEET &100 FEET IS 40.IT DOES NOT RECOGNIZE A CAR THAT PULLS IN FRONT OF YOU THAT IS A CAR LENGTH AWAY & DOES NOT SLOW DOWN.IF A CAR MOVES OUT FROM IN FRONT OF YOU,THE CAR DOES NOT RECOGNIZE THE CAR THAT WAS IN FRONT OF THE OTHER CAR THAT LEFT YOUR LANE, YOUR CAR SPEEDS UP AND DOES NOT SLOW DOWN FOR THAT CAR IN FRONT AND YOU HAVE TO SHARPLY BRAKE.MY CAR SLOWS DOWN TOO LATE ALL THE TIME AND I HAVE TO APPLY THE BRAKES WHEN THEY SHOULD HAVE BEEN APPLIED AUTONOMOUSLY & BRING THE CAR TO A FULL STOP FROM THE CAR IN FRONT MAINTAINING THE PRE SET DISTANCE.THIS HAPPENS USING IT ON SIDE ROADS AND ON THE HIGHWAY. THE AUTONOMOUS BRAKING SUPPOSE TO HAPPEN AT ALL SPEEDS.MY CAR HAS THE DRIVER ASSISTANCE PKG.NONE IN THAT PKG WORK WELL, IF AT ALL. I HAD AN AUDI Q7 WITH THE SAME TYPE OF CRUISE CONTROL,I NOW HAVE A 2015 AUDI Q7 WITH IT.I HAVE HAD 2 FORD EDGE'S , 2 LEXUS LS450'S AFTER THE LEXUS I PURCHASED A 2007 MERCEDES S-550 WITH IT .IN ALL THOSE CARS IT WORKED EXCEPTIONALLY WELL. AUTONOMOUS BRAKING AND PRE SAFE AND DISTRONIC CRUISE AND ALL OF THE DRIVER ASSISTANCE PACKAGES AVAILABLE THEN WERE AMAZING IN THE 2007 AND I FELT SAFE IN THAT CAR. I DO NOT FEEL SAFE AT ALL NOW. IF YOU HAVE NOT GOTTEN ANY OTHER COMPLAINTS IT IS BECAUSE THEY DO NOT UNDERSTAND THE SYSTEMS OR HAVE THE SAME EXPERIENCE AS I DO WITH THE SAFETY SYSTEMS. OR MERCEDES LIED.
