STRUCTURE:BODY, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
DATE: APRIL 13, 2021. MODEL: C300 YEAR : 2018 MILAGE: 16,000. TIME: 2.30 P.M. WHETHER: SUNNY. ROAD CONDITION: SMOOTH PROBLEM: WHILE DRIVING ON 405 SOUTH AT SPEED OF APPROX 65 TO 70 MPH FOR NO APPARENT REASON , THE CAR UDDENLY , UNEXPECTEDLY, AND FORCEFULLY SLAMMED ON THE BRAKES ( 65 TO 0 MPH) IN MATTER OF SECONDS, AND LOCKED ITS WHEELS. LEFT ME STOCK ON THE FWY. THE MOST SCARIEST EXPERIENCE AS YOU DON'T KNOW WHAT IS GOING ON OR WHAT IS GOING TO HAPPEN TO . LUCKILY THERE WERE NO VEHICLES IN MY CLOSE PROXIMITY OR WE COULD HAVE DIED ! THE WARNING SIGNS WERE ON " INOPERATIVE BREAK ASSIST SYSTEM" . THE CARS FORCE WAS SO STRONG THAT NOT ONLY JOLTED MY HEAD BACK AND FORTH, IT CAUSED MY COMPUTER TO FLY FROM THE BACK SEAT AND HIT MY HEAD IN THE FRONT SEAT. I HAD TO REPLACE THE VEHICLES SENSORY RADAR ABOUT FOUR MONTHS AGO BACK IN NOV 2020. I SEE THAT MBZ HAS RECALLED ITS 2019 MODELS AND MANY OTHER MODELS ( SOFTWARE GLITCH THAT CAN SLAM THE BREAK UNEXPECTEDLY). WHY RECALL C300 2019 AND NEWER MODELS AND NOT ALL MODELS WITH THIS DEFECTIVE SENSOR SYSTEM.. IT WILL TAKE THEM 30 MINUTES TO REPROGRAM EACH CARS SOFTWARE, YET, ARE NOT DOING IT AND ENDANGERING THE PUBLIC. WHAT HAPPENED TO ME WAS A VERY SCARY INCIDENT AND HOPE THAT YOU CAN GET THEM TO RECALL MY VEHICLE . I AM SCARED TO DRIVE IT AGAIN AS IT COULD HAPPEN AGAIN!

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
AUTOMATIC EMERGENCY BRAKING ENGAGES UNNECESSARILY WHEN DRIVING UNDER CHICAGO'S ELEVATED TRAIN TRACKS AND SIMILAR OVERHEAD STRUCTURES. FOR EXAMPLE, WHEN DRIVING ON WABASH AVE IN CHICAGO'S DOWNTOWN LOOP, OR ON LOWER WACKER DRIVE, THE AUTOMATIC EMERGENCY BRAKING ENGAGES WHEN THERE IS NO RISK OF A COLLISION, PARADOXICALLY CREATING A DANGEROUS DRIVING SITUATION. THE DEALERSHIP IS AWARE THIS HAPPENS IN OTHER SIMILAR VEHICLES, AND WHEN I BROUGHT THE ISSUE TO THEIR ATTENTION, SUGGESTED I MERELY CHANGED ROUTES.

TIRES, TIRES:TREAD/BELT
TIRE BRAND: SUMITOMO TIRE LINE: HTR A/S P02 TIRE SIZE: 225/40R18 92W COMPONENT: BUBBLE IN TREAD AREA, NOT SIDEWALL DOT NUMBER: LM6R2916 AND LM6R2416 TWO FRONT TIRES WERE PUCHASED NEW FROM AMAZON.COM IN MAY OF 2017 AND WERE IMMEDIATELY INSTALLED AND PUT INTO SEVICE. THERE WERE APPROXIAMATELY 30K MILES ON THE TIRES. THE FIRST FRONT TIRE FAILED IN JULY OF 2020 (LM6R2916) AND THE SECOND FRONT TIRE FAILED IN APRIL OF 2021 (LM6R2416). NO SPECIFIC EVENTS LED TO THE FAILURE OF EACH TIRE AND OCRRUED DURING NORMAL DRIVING. THE FIRST TIRE STARTED MAKING A WEIRD WOBBLING NOISE AT HIGHWAY SPEEDS. INSPECTION REAVEALED ON LARGE BUBBLE ON THE INNER PORTION OF THE TREAD. THE SECOND TIRE FAILURE OCCURRED AFTER STRANGE NOISES AS IF A ROCK WAS STUCK IN THE TIRE. INSPECTION REVEALED A SMALL BUBBLE FORMING ON THE INNER TREAD. ALL FOUR TIRES WERE REPLACED. A WARRANTY CLAIMED WAS ATTEMPTED WITH SUMITOMO. THEY REFUSED TO HONOR A WARRANTY AND TOLD ME THE VENDOR WOULD TAKE CARE OF THE WARRANTY CLAIM. AMAZON.COM REFUNDED THE PURCHASE PRICE.

FUEL/PROPULSION SYSTEM
STRONG GASOLINE SMELL WHEN I FILL MY TANK UP AND PARK MY CAR INSIDE MY GARAGE. SO STRONG THAT I WORRY ABOUT EXPLOSION DUE TO MY WATER HEATER WITH PILOT LIGHT IN THE GARAGE. I FREQUENTLY OPEN THE GARAGE DOOR TO LET THE ACCUMULATED GAS ODOR DISSIPATE OR HAVE TO MOVE THE CAR OUTSIDE. STRONG GASOLINE SMELL GOES AWAY ONCE THE FUEL LEVEL GOES DOWN ABOUT 1/8 TO 1/4. THIS HAS BEEN GOING ON SINCE 12/20/2020.

FUEL/PROPULSION SYSTEM
VERY STRONG FUEL ODOR INSIDE CABIN OF VEHICLE WHILE DRIVING. ODOR IS VERY STRONG AROUND DRIVERS REAR WHEEL AND FROM THE OUTSIDE ONCE PARKED. SMELL OF FUEL IS VERY STRONG AT TIMES WHILE DRIVING BUT SEEMS TO DISSIPATE WHEN DRIVING AT A FASTER SPEED I.E. ON HIGHWAY OVER 45MPH. ONCE I COME TO A STOP OR DRIVE BELOW 45MPH THE SMELL IS PRONOUNCED PROBABLY BECAUSE IT ISN'T BEING BLOWN AWAY FROM THE VEHICLE WHILE DRIVING. DOES NOT CHANGE IN CORRELATION TO FUEL TANK FILL LEVEL. INSPECTED FUEL SENDER UNDER ACCESS CAP, UNDERNEATH REAR PASSENGER BENCH DRIVER'S SIDE ON APRIL 9TH 2021. FOUND FUEL PUDDLING IN/AROUND THE EXTERIOR OF FUEL SENDING UNIT. CLEANED OUT FUEL PUDDLE. MOST OF THESE SYMPTOMS ARE ALSO SIMILAR TO CASE WITH THE 2003-2006 MERCEDES BENZ E55 AMG AND CLS VEHICLES FOUND UNDER NHTSA ACTION NUMBER: EA13003 REGARDING EMISSIONS RECALL FOR AMG MODELS USING HIGH PRESSURE FUEL SYSTEMS.

DOCUMENTATION ERRORS AND OMISSIONS MISINFORMATION REGARDING PROPER REPLACEMENT WHEEL. THIS MISINFORMATION COULD RESULT IN WHEELS WITH IMPROPER FIT BEING INSTALL POTENTIALLY RESULTING IN ABNORMAL HANDLING, DIMINISHED BRAKING PERFORMANCE AND IN EXTREME CASES POSSIBLE SEPARATION OF THE WHEEL FROM THE VEHICLE AT HIGH SPEED. MERCEDES PARTS WEB SITE, HTTPS://MBPARTS.MBUSA.COM, LISTS PARTS 205-401-11-00-7X23 FRONT AND 205-401-12-00-7X23 REAR AS THE PROPER REPLACEMENT WHEELS. THE SELLING DEALER, MERCEDES-BENZ OF FLEMINGTON, NJ INSISTS THAT THESE ARE NOT THE PROPER WHEELS BUT PARTS 205-401-48-00-7X23 FRONT AND 205-401-72-00-7X23 REAR ARE THE PROPER WHEELS. ALL THESE WHEELS ARE AVAILABLE FROM NUMEROUS RESELLERS. PURCHASING AND INSTALLING THE HTTPS://MBPARTS.MBUSA.COM LISTED WHEELS COULD RESULT IN THE AFOREMENTIONED SAFETY ISSUES.

WHEELS
WHEEL LIPS ON THIS VEHICLE DEFORM WITH LITTLE PROVOCATION RESULTING IN RAPID AIR LOSS, LOSS OF HANDLING AND IN EXTREME CASES A CRASH. THE SHAPE OF THESE WHEELS DEVIATES FROM OTHER ALLOY WHEELS IN A WAY THAT PROMOTES THIS BEHAVIOR. THE CURVE OF THE RIM BARREL BETWEEN THE LIPS (ALSO KNOW AS THE BELL) IS MUCH SHALLOWER THAN MANY OTHER WHEELS. THE RESULT IS THAT THE ANGLE AT WHICH THE BARREL MEETS THE LIPS IS CLOSER TO A RIGHT ANGLE THAN COMMON. THE BARREL MEETING THE LIP AT AN ANGLE CLOSER TO PARALLEL WITH THE PAVEMENT GREATLY INCREASE THE RISK THAT SUDDEN DEFLATION COULD OCCUR RESULTING IN THE AFOREMENTIONED SAFETY ISSUES.

FUEL/PROPULSION SYSTEM
THERE IS A RAW FUEL SMELL INSIDE THE CABIN OF THE CAR WHEN DRIVING. I LOOKED ONLINE AND FOUND THAT THERE IS A LAWSUIT AGAINST MERCEDES-BENZ FOR FAULTY FUEL LINES THAT THEY ARE REFUSING TO REPAIR. I AM HAVING THE SAME ISSUES WITH THE FUEL LINES AS COUNTLESS OTHER PEOPLE HAVE WHERE THE RUBBER HOSES ARE FAILING PREMATURELY. I HAVE A 2016 C300 WITH ONLY 37,100 MILES ON IT THAT IS KEPT UP ON AND THE DEALERSHIP IS SAYING THAT THE FUEL LINES ARE TYPICAL WEAR ITEMS AND THAT THE CPO WARRANTY DOES NOT COVER THE REPAIR. THIS IS A SAFETY ISSUE AS IT COULD CAUSE A FIRE AND LEAKING FUEL INTO THE ENVIRONMENT AND FUEL LINES SHOULD NOT NEED TO BE REPLACED ALREADY.

ENGINE
MY 2016 C300 4MATIC, WHICH HAS BEEN SERVICED EXCEPTIONALLY WELL, TURNED 57,000 MILES (7K MILES OUTSIDE OF WARRANTY), HAD THE CHECK ENGINE LIGHT TURN ON. I WENT TO MY MECHANIC, WHO HAS A STATE OF THE ART DIAGNOSTIC UNIT, AND IT WAS DIAGNOSED AS CODE P052E WHICH MEANS THAT THE CRANKCASE VENTILATION REGULATOR VALVE INCLUDING THE FUEL RAIL NEEDS TO BE REPLACED. MERCEDES HAS KNOWN ABOUT THIS BEING A MAJOR PROBLEM AS THEY MODIFIED ONE OF THE PARTS. MY DEALERSHIP QUOTED ME OVER $ 2100.00 TO FIX IT AND DEEMED IT NOT COVERED BY THE EXTENDED WARRANTY. I HAVE GONE ONLINE TO SEVERAL MERCEDES BENZ FORUMS AND HUNDREDS OF PEOPLE HAVE HAD THE SAME THING HAPPEN WITH THIS PART FAILING AROUND 52K MARK. SINCE MERCEDES KNEW ABOUT THIS - ISSUED AN IMPROVED PART TO REPLACE THE DEFECTIVE ONE - NHTSA SHOULD MANDATE A RECALL. THIS IS NOT SOME SIMPLE DYI MATTER. IT IS A COMPLICATED REPAIR CONSUMING MANY HOURS. IT IS WRONG THAT DRIVING THIS, WITH THIS CODE, COULD LITERALLY KILL YOU. I IMPLORE NHTSA TO MANDATE A RECALL BASED ON THE FACTS SPECIFIED HEREIN. BY THE WAY I HAVE A 1999 ML320 THAT I HAVE METICULOUSLY MAINTAINED AND DRIVES PERFECT AND I HAVE OWNED MANY OTHER MERCEDES BENZ. I AM 58 YEARS OLD AND I HAVE NEVER FILED A COMPLAINT WITH NHTSA BEFORE. THIS IS A VERY SERIOUS MATTER. PLEASE HELP

ENGINE
THIS CAR IS NOT EQUIPPED WITH ENOUGH PROTECTION FOR THE FRONT RADIATORS TO PREVENT DAMAGE FROM DEBRIS. THIS IS A KNOWN ISSUE FOR 2017 AND UP VEHICLES. THE RADIATOR SEEMS TO BE VERY FRAGILE DUE TO THE DESIGN AND THERE HAVE BEEN MANY REPORTS OF THE ISSUE, BUT CLAIMS ARE DENIED DUE TO BEING 'ROAD DEBRIS' BUT MERCEDES-BENZ FAILS TO ACKNOWLEDGE THIS IS A MAJOR ISSUE WITH MULTIPLE CLASSES OF THEIR CARS. MY CAR HAS 27K MILES AND IS JUST OUTSIDE THE WARRANTY PERIOD. THE RADIATOR IS LEAKING IN MULTIPLE PLACES.
