2015 Mercedes-Benz C300 problems and owner complaints

I STARTED THE ENGINE AND THE POWER STEERING FAILURE WARNING CAME ON. TRUE ENOUGH, IT WAS A STRUGGLE TO STEER MY CAR BACK HOME - I WAS JUST 3 MINUTES AWAY FROM HOME. THE CAR WAS TOWED THE NEXT MORNING TO AUTOHAUS ON EDENS IN NORTHBROOK, IL. I DID A GOOGLE SEARCH AND FOUND OUT THAT THERE HAS BEEN A RECALL FOR THIS EXACT PROBLEM IN EUROPE SINCE DEC 2014. I WAS SHOCKED THAT OWNERS IN THE US WERE NOT WARNED OF THIS POTENTIAL PROBLEM AND THERE HAS BEEN NO RECALL ISSUED. IF THIS HAD HAPPENED ON THE FREEWAY, IT LIKELY WOULD HAVE RESULTED IN A VERY SER…

THE STEERING MALFUNCTION LIGHT CAME ON AND THE STEERING WHEEL LOST POWER. THE STEERING WHEEL LOCKED UP WHERE IT BECOME EXTREMELY DIFFICULT FOR ME TO MANEUVER THE CAR.

WHEN I TURNED MY CAR BACK ON AFTER APPROXIMATELY 5 MINS, THE ERROR WAS GONE AND IT WAS CLOSE TO 7PM AND THE SERVICE CENTER FOR …

THERE IS A FUEL HOSE (PARTS NUMBER: [phone removed]) CONNECT TO THE HIGH PRESSURE PUMP IN FRONT ENGINE AREA. THE FUEL HOSE WAS FASTENED BY A CLAMP (NOT SURE THE PARTS NUMBER) . BECAUSE OF THE DESIGN FLAW, THIS CLAMP WILL LOOSE SINCE IT'S A SNAP JOINT ASSEMBLIES NOT TIGHTEN BY SCREWS. UNDER THIS SITUATION, THE FUEL HOSE WILL LOOSE AND AFFECTED BY THERMAL EXPANSION, THIS PROBLEM WILL CAUSE FUEL LEAK/SEEPING. WE CAN SMELL FUEL NEAR THE PUMP BEFORE WE START CAR IN COLD IN THE MORNING AND THIS SMELL CAN BE SMELLED UNTIL THE ENGINE WORKING INTO THE N…

THE 7 SPEED TRANSMISSION SHIFTS VERY HARD FROM 1 GEAR TO 2 GEAR TO 3 GEAR. FROM 3 GEAR ALL THE WAY TO 7 GEAR IS VERY SMOOTH. ALSO THE SAME WAY AROUND WHEN YOU DOWNSHIFT FROM 3 GEAR TO 2 GEAR TO 1 GEAR. THE SLOWING DOWN IS VERY HARSH AND IT LOOKS LIKE THE TRANSMISSION DOESN'T UNDERSTAND THAT THE CAR IS GOING TO A FULL STOP. ALL THE POWER AND SPEED CUT DOWN A FEW SECONDS BEFORE FULL STOP. I HAVE PERSONALLY TRIED TO DO THE RESET WITH KEY AND PEDAL TRICK BUT IT ONLY WORKS FOR A DAY OR TWO AND GOES RIGHT BACK TO THE ROUGH SHIFTING.

The local dealer tried to reprogram the software, but the problem still persists. When plugging in my OBD II & DTC readers, code U0103 appairs which translates to "Lost communication with gear shift control module". My concern with this is that I've had this issue while in traffic, which would make my vehicle a hazard. When it comes to the collision preventio…
