THERE WERE NO INJURIES SUSTAINED. A POLICE REPORT WAS FILED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS AWAITING A DIAGNOSIS AND REPAIRS. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE.

WHILE DRIVING ON THE HIGHWAY IN THE PASSING LANE, A WARNING MESSAGE INDICATED THE ACCIDENT AVOIDANCE SYSTEM WAS MALFUNCTIONING. THIS DEACTIVATED THE ACCELERATOR, I HAD NO CONTROL OF THE CAR, SQUEEZED BETWEEN CARS AND COASTED TO A STOP. TURNED OFF CAR AND CALLED MERCEDES. CAR WAS RESTARTED WITH NO ISSUES INDICATED, DROVE THE CAR HOME. NEXT DAY ON THE HIGHWAY DID IT AGAIN, WENT DIRECTLY TO DEALERSHIP. THEY HAD THE CAR 4 DAYS, SAID IT WAS A COMPUTER CODE ISSUE AND WAS FIXED. LESS THAN A MONTH LATER IT DID IT AGAIN DRIVING 25MPH IN MY NEIGHBORHOOD. CALLED MERCEDES, THEY ARE PICKING THE CAR UP. I NO LONGER TRUST THE CAR, WILL NOT LET FAMILY DRIVE IT BECAUSE IT BECOMES DISABLED....

I HAD TWO ISSUES WITHIN 2 MONTHS OF BUYING THE CAR EARLIER IN THIS. I PURCHASED THE CAR IN EARLY FEB 2015. I HEARD A LOUD SOUND IN THE HEATING UNIT, THEN A SMALL CLICKING SOUND ENSUED FOR OVER A WEEK. BROUGHT IT IN, THE MOTOR HAD BLOWN, SO THEY REPLACED IT WITHOUT A DIME OUT OF MY POCKET. THEN IN MARCH, I WAS DRIVING ABOUT 35 MILES PER HOUR WHEN A VERY LOUD NOISE LIKE BAD BREAKS STARTED AND WOULDN'T STOP NO MATTER WHAT I DID. WE TOWED IT USING MERCEDES, BUT HAD TO PAY FOR AN UBER TO THE DEALERSHIP. IT WAS AGAIN ANOTHER MALFUNCTION WITH THE NEW MODEL, AND THEY FIXED THE BREAKS AND ROTORS THAT SAME DAY WITHOUT A DIME OUT OF MY POCKET. I NOW HAVE 6500 MILES ON IT SINCE I GOT IT IN FEB THIS YEAR, AND THE CHECK ENGINE LIGHT CAME ON. I TRIED TO REPLACE THE FUEL CAP BUT THAT DIDN'T MAKE IT GO AWAY AND THE CAR IS DRIVING FINE. IM BRINGING IT IN LATER THIS WEEK. I SAW REPORTS THAT THERE ARE SOME CARS WITH THIS FUEL ISSUE THATS CAUSING THIS INDICATOR. OVERALL THIS ONE PARTICULAR CAR I LEASED IS A TOTAL DUD, BUT I HOPE THESE REPORTS HELP OTHERS WITH SIMILAR ISSUES.

I SAT IN THE CAR, HAD NOT STARTED IT YET, AND A "POWER STEERING MALFUNCTION, SEE OPERATORS MANUAL" WARNING IN RED WAS ON DASHBOARD SCREEN, AND ANOTHER SMALLER RED INDICATOR LIGHT OF A STEERING WHEEL WAS ON IN THE SPEEDOMETER AREA. STARTED THE CAR AND THE WARNINGS REMAINED. SHUT IT OFF AND IMMEDIATELY RESTARTED AND THE WARNINGS REMAINED. STARTING DRIVING THE CAR AND THE POWER STEERING WAS INDEED OUT. I HAD GREAT DIFFICULTY TRYING TO STEER, ESPECIALLY UNDER 5MPH. DROVE ABOUT A MILE AND THEN PARKED AND SHUT THE CAR OFF. CAME BACK ABOUT 10 MINUTES LATER, RESTARTED THE CAR AND THE WARNINGS WERE GONE AND STEERING WAS BACK TO NORMAL.

UNABLE TO MOVE DRIVER'S POWER SEAT FORWARD INTO SAFE OPERATING POSITION. HAD TO DRIVE CAR BY SITTING ON FRONT EDGE OF THE SEAT. BROUGHT TO DEALER FOR SERVICE AND SEAT OPERATION WAS RESTORED TO NORMAL AFTER A SOFTWARE RESTORE/RESET. SERVICE CONSULTANT COULD PROVIDE NO DEFINITE INFORMATION AS TO WHAT IS THE CAUSE OF THE PROBLEM. THE NEXT DAY IN THE MORNING, THE PROBLEM REOCCURED. I AM CONCERNED THAT THIS IS A CHRONIC PROBLEM THAT CANNOT BE REPAIRED. IT IS A BRAND NEW VEHICLE AND I DON'T KNOW IF THIS IS SOMETHING THAT AFFECTS OTHER VEHICLES.

I WAS DRIVING ON A RURAL BACK ROAD AT 30 MILES, THE POWER STEERING STOPPED WORKING. A WARNING APPEARED SAYING "MALFUNCTION OF POWER STEERING". I WAS ABLE TO DRIVE HOME, ABOUT ONE MILE, BUT WITH GREAT DIFFICULTY. I CALLED MERCEDES BENZ. THEY SENT A TOW TRUCK AND TOWED AUTO TO WESTWOOD MERCEDES IN WESTWOOD, MA. I WAS INFORMED IT WAS A SOFTWARE PROBLEM AND IT HAD BEEN REPROGRAMMED.

MY VEHICLE, A 2015 MERCEDES-BENZ C300 PURCHASED ON 6/6/15 WITH APPROXIMATELY 1200 MILES ON THE ODOMETER. ON MONDAY MORNING 7/20/15, AT APPROXIMATELY 5:30 AM PDT, I WAS DRIVING ON THE FREEWAY WHEN THE INTERIOR LIGHTS CAME ON AND THE DRIVERS DOOR POPPED OPEN. THERE WAS NO WARNING CHIME OR INDICATOR LIGHT PRIOR TO THIS HAPPENING. IT WAS VERY FRIGHTENING, AND CAUGHT ME BY SURPRISE. LUCKILY AT THE TIME THERE WERE NO OTHER CARS NEAR ME. I WAS ABLE TO SLOW DOWN AND SHUT THE DOOR. I CALLED THE DEALER AND THEY WERE CONCERNED AND HAD ME DROP IT OFF THAT AFTERNOON. PICKED UP ON TUESDAY AFTERNOON 7/21/15 APPROXIMATELY 5:30 PM PDT. I WAS TOLD THEY COULDN'T DUPLICATE THE DOOR OPENING. HOWEVER, LOOKING AT FORUMS ON THE INTERNET, THIS EXACT ISSUE HAS BEEN REPORTED BY OTHERS IN THE US AND AUSTRALIA AT LEAST. SOME WERE THE DRIVERS DOOR OTHERS WERE THE PASSENGERS DOOR. ONE REPORTED IT HAPPENING A SECOND TIME AFTER THE DEALER INSPECTED. I AM VERY CONCERNED ABOUT THIS HAPPENING AGAIN, AND POSSIBLY TRIGGERING AN AIR BAG OR AUTO-PARK. I DO NOT FEEL SAFE IN THIS CAR. I HAVE CONTACTED MERCEDES-BENZ USA VIA CHAT THIS MORNING 7/22/15 AND THEY WILL HAVE A CASE MANAGER CONTACT ME.
