UNKNOWN OR OTHER
THE AUDIBLE TIC-TOK SOUND OF THE TURN SIGNAL IS WAY TOO SOFT. THE SOUND IS SUPPOSED TO GIVE ONE NOTICE THAT THE TURN SIGNAL IS ON. IT SIMPLY ISN'T LOUD ENOUGH TO PROVIDE THAT FEEDBACK. CONSEQUENTLY I OFTEN FIND THAT I'M DRIVING DOWN THE STREET HAVING COMPLETED A HALF-TURN ( ONE WHERE IT DOESN'T TRIGGER A SHUT OFF) WITH MY TURN SIGNAL ON FOR BLOCKS BEFORE I NOTICE THAT THE TURN BLINKER IS STILL ON.

ENGINE, POWER TRAIN
THIS VEHICLE IS UNSAFE. WHEN DRIVING IN TRAFFIC THE ENGINE/TRANSMISSION WILL NOT DELIVER POWER IN RESPONSE TO THROTTLE APPLICATION, IT IS ALSO INCONSISTENT IN IT'S RESPONSE FROM ONE TIME TO THE NEXT. THE VEHICLE WILL HESITATE FOR UP TO 4-5 SECONDS BEFORE RESPONDING TO THROTTLE COMMANDS WHEN PULLING OUT INTO TRAFFIC. THIS IS MOST NOTICEABLE WHILE ROLLING BETWEEN 5-10 MPH AND APPLYING POWER ALSO WHILE MAKING A SHARP TURN. THE POWERTRAIN ALSO IS EXTREMELY INCONSISTENT IN IT'S RESPONSE WHICH MAKES PULLING INTO TRAFFIC EXTREMELY DANGEROUS. I SUSPECT THE PROBLEM STEMS FROM SENSORS IN THE ELECTRONIC STABILITY PROGRAM (MB ESP), THE TRANSMISSION MODULE AND THE FLY BY WIRE THROTTLE AND ENGINE CONTROL MODULE. PROGRAMING OF SHIFTS OF THE TRANSMISSION SEEM TO FIGHTING WITHIN THE TRANSMISSION ITSELF. ALL OF THIS ADDS UP TO AN EXTREMELY DANGEROUS SITUATION WHEN DRIVING IN TRAFFIC. I HAVE TAKEN THE VEHICLE BACK TO THE SELLING DEALER (MERCEDES BENZ OF NORTH PALM BEACH FLORIDA) TWICE ONLY TO BE TOLD THAT THIS IS NORMAL. I FILED A REQUEST WITH MERCEDES BENZ OF NORTH AMERICA TO BUY THE CAR BACK WITHOUT SUCCESS.

SEAT BELTS
THE SEAT BELT LATCH PLATES (THE PARTS THAT INSERT INTO THE BUCKLES) FOR THE REAR SEAT RETRACTED INTO THE INTERIOR PANELING, PREVENTING THE OCCUPANT FROM BEING ABLE TO USE THE SEAT BELT. (REFER TO SIMILAR RECALL # 18V177000). ALTHOUGH THERE WAS A RECALL FOR THE SAME ISSUE, MY VIN WAS NOT INCLUDED. I WAS ULTIMATELY ABLE TO FIX IT ON MY OWN BY FISHING IT OUT FROM THE INTERIOR PANEL WITH MY FINGERS WHICH WAS DIFFICULT TO DO. IT IS NOT CLEAR HOW IT HAPPENED, BUT WE THINK IT WAS AFTER THE REAR SEAT WAS DOWN AND WHEN IT WAS RETURNED TO IT'S NORMAL POSITION IT PUSHED THE LATCH PLATE INTO THE INTERIOR. WE CONTACTED OUR LOCAL MB DEALERSHIP AND WERE TOLD NOTHING COULD BE DONE SINCE THE VIN WAS NOT ON THE RECALL EVEN THOUGH WE HAD THE SAME EXACT ISSUE AS THE RECALL.

SERVICE BRAKES
BRAKES SCREECH LOUDLY WHEN IN REVERSE CAUSING NOISE DISTURBANCE AND CONCERN ABOUT POSSIBLE SAFETY ISSUE. THIS HAS BEEN AN ON-GOING PROBLEM FOR SEVERAL MONTHS AND IS GETTING PROGRESSIVELY WORSE. APPARENTLY, THIS DEFECT WITH BRAKES IS WELL KNOWN TO MERCEDES-BENZ BUT THEY HAVE NOT ISSUED A PROPER FIX OR RECALL FOR THE PROBLEM. VEHICLE PURCHASED PRE-OWNED FROM MERCEDES-BENZ DEALERSHIP IN WALNUT CREEK IN 2018.

ENGINE
I PURCHASED THIS CAR IN 08/2018 WITH 900MILES CERTIFIED PRE OWN. I HAVE TAKEN IT TO DEALER 4 SEPARATE OCCASIONS FOR ENGINE LIGHT. EACH TIME THEY HAVE KEPT IT FOR OVER 2 WKS. THIS LAST TIME THE ENGINE LIGHT WENT ON IN MAY 2020. WE WERE ON FREEWAY GOING ABOUT 70MPH WHEN THE ENGINE WENT ON AND THE CAR LOST POWER AND CAME TO ALMOST A COMPLETE STOP IN MIDDLE OF FREEWAY. I HIT MY HEAD ON FRONT WINDSHIELD DUE TO THE IMPACT. THE DEALER STATES IT HAS BEEN REPAIRED BUT SAME PROBLEMS OCCUR ALMOST MONTHLY. *TR

FEELS LIKE IT TOO

FUEL/PROPULSION SYSTEM
LEAKAGE IN FUEL SYSTEM ( HIGH PRESSURE PUMP). ON GLC 300. GAS SMALL INSIDE THE CAR. COMPANY DENIED INVESTIGATING OR PROVIDING MY REFUND FOR REPAIR. I FEEL THIS IS TOTALLY SAFETY FAILURE OF THE VEHICLE . SO MY CURRENT MILEAGE IS 32908 AND IT IS 2016 MODEL. I BOUGHT THIS VEHICLE BECAUSE THE COMPANY CLAIMS FOR ITS HIGHEST STANDARDS OF SAFETY. SO I WANT THE AUTHORITY TO HELP ME IN INVESTIGATING THIS ISSUE AND PROVIDE ME ASSURANCE AND COVERAGE FOR ANY KIND OF SAFETY ISSUES IN FUTURE. ALSO, I WANT TO REPORT SOME MINOR ISSUES ON BREAKS. I SEE SOMETIME THE THERE IS A DELAY IN ACTION. HOPE THIS WILL BE INVESTIGATED FOR PREVENTIVE ACTIONS AND GET MY REFUND FOR FIXING THIS KIND OF SAFETY RELATED MATTERS. ITS IS TOTAL RESPONSIBILITY OF MANUFACTURER TO DELIVER THE SAFETY VEHICLE. NOT TO ESCAPE BY SAYING WARRANTY CLAUSE

STEERING
THE VEHICLE WONDERS WITHIN THE LANE WHEN MERCEDES DISTRONIC DRIVER ASSISTANCE IS ACTIVATED, PARTICULARLY ON GENTLE CURVES AT HIGHWAY SPEEDS. IT WILL HIT LANE BUMPS UNLESS THE DRIVER ACTIVELY STEERS AWAY FROM THE LANE MARKINGS. THE 2020 GLC3004MATIC HAS BEEN DOING THIS SINCE WE PURCHASED IT NEW ON JANUARY 2, 2020. MERCEDES DEALER HAS CHECKED THE VEHICLE AND IS NOW DESCRIBING THE VEHICLES BEHAVIOR AS NORMAL. ACCORDING TO MERCEDES THIS IS A NEW DRIVER ASSISTANCE PACKAGE IN THE 2020 GLC. IT IS A MAJOR SAFETY HAZARD IF THE VEHICLE IS NOT ACTIVELY CONTROLLED BY THE DRIVER AT ALL TIMES. THIS IS NOT AN ASSISTANCE PACKAGE AS DESCRIBED BY MERCEDES. WE HAVE DRIVEN OLDER MERCEDES WITH THE DISTRONIC SYSTEM THAT STAYED IN THE LANE VS. THE WONDERING. WE DO NOT TAKE OUR HANDS OFF THE STEERING WHEEL THE VEHICLE DOES THIS ON IT'S OWN PRIOR TO ANY WARNINGS RELATED TO DRIVER AWARENESS OR ACTIONS. THIS ACTION BY THE VEHICLE WHEN DISTRONIC IS ACTIVATED WILL CAUSE SERIOUS LIFE THREATENING ACCIDENTS.
