2017 MERCEDES-BENZ GLC300 Complaints

What component or system failed or malfunctioned, and is it available for inspection upon request? Car is at Mercedes dealer for repair. How was your safety or the safety of others put at risk? Yes, car lost acceleration on freeway and put other drivers at risk on the road. Lucky to get off freeway and pull over without any injuries. Has the problem been reproduced or confirmed by a dealer or independent service center? Dealer provided feedback cracked piston, cylinder # 2. Reading on forums, others continue to have the same issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Inspected by Mercedes bens manufacturer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? in retrospect, some slow acceleration delays 1-2 days prior, but not consistent.

WHILE DRIVING, THE MALFUNCTION INDICATOR LAMP (MIL/CHECK ENGINE LIGHT) CAME ON. AFTER SOME DIGGING THIS WAS CAUSED BY AN OBD II CODE OF P052E, WHICH INDICATES A BLOCKED CRANKCASE VENT VALVE ACTUATOR. THIS APPEARS TO BE A MANUFACTURING DEFECT IN THESE VEHICLES.

SMELLS LIKE GAS COMING THROUGH THE VENTS INTO THE CABIN OF THE VEHICLE AND CAUSES HEADACHES

1. CRANKCASE VENTILATION VALVE PERFORMANCE FAILED CHECK ENGINE LIGHT IS ON WHILE DRIVING 2. SMELLS GAS FROM UNDER THE HOOD. HEARD IT'S COMMON PROBLEMS

TL* THE CONTACT OWNS A 2017 MERCEDES-BENZ GLC300. THE CONTACT STATED WHILE ATTEMPTING TO MAKE A U-TURN, SHE HEARD AN ABNORMAL SOUND. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. THE CONTACT STATED THE FOLLOWING DAY, SHE NOTICED THE STEERING WHEEL FEATURES INCLUDING THE HORN AND AIR BAG WERE INOPERABLE. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER HOFFMAN LEXUS (750 CONNECTICUT BLVD, EAST HARTFORD, CT 06108, (860) 525-3987) AND THE DEALER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER NEW COUNTRY MERCEDES-BENZ (1 WESTON ST, HARTFORD, CT 06120, (860) 278-2000) WHERE IT WAS DIAGNOSED WITH NEEDING THE CLOCK SPRING TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED AS OF YET. THE MANUFACTURER HAD NOT BEEN INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 60,000.

TL* THE CONTACT OWNS A 2017 MERCEDES BENZ GLC300. THE CONTACT STATED THAT WHILE HIS WIFE WAS DRIVING APPROXIMATELY 40 MPH, THE VEHICLE CRASHED INTO A 2ND VEHICLE. DURING THE CRASH THE FRONT END WAS SEVERELY DAMAGED BUT THE AIR BAGS DID NOT DEPLOY. ALSO, THE COLLISION AVOIDANCE SYSTEM MALFUNCTIONED AND DID NOT STOP THE VEHICLE TO AVOID THE COLLISION. THE DRIVER SUSTAINED BRUISES TO THE TORSO AREA WHICH REQUIRED MEDICAL TREATMENT. AN OCCUPANT FROM THE 2ND VEHICLE WAS TRANSPORTED TO THE HOSPITAL BY AMBULANCE. NO FURTHER INFORMATION WAS AVAILABLE. A POLICE REPORT WAS TAKEN AT THE SCENE AND THE VEHICLE WAS TOWED AWAY. THE LOCAL DEALER MERCEDES BENZ OF HUNTSVILLE (6220 UNIVERSITY DR. HUNTSVILLE, AL) AND THE MANUFACTURER WERE NOTIFIED OF THE INCIDENT. THE CAUSE OF THE FAILURES WERE NOT DETERMINED. THE FAILURE MILEAGE WAS 25,000.

TRAVELING 60 MPH ON INTERSTATE, WHEN STEERING WHEEL JERKED TO THE RIGHT AND THEN LEFT, BRAKES AUTOMATICALLY ACTIVATED, AND SEAT BELT TIGHTENED. LASTED FOR APPROXIMATELY 3 MILES, THEN JERKING STOPPED. WITHIN ANOTHER 30 MILES HAPPENED 3 MORE TIMES. EACH TIME AN ALERT APPEARED ON DISPLAY 'BLIND SPOT ASSIST IS DEACTIVATED, NOT OPERATIONAL'. STOPPED AND HAD CAR WASHED TO REMOVE ANY DEBRIS FROM SENSORS, BUT PROBLEM PERSISTED. HAPPENED AGAIN TODAY, 5/2, AT 45 MPH ON PUBLIC HIGHWAY. CRUISE CONTROL WAS NOT ENGAGED WHEN THESE INSTANCES OCCURRED. TERRIFYING! I HAD TO FIGHT THE WHEEL TO KEEP CONTROL.

BOUGHT CAR 3 DAYS AGO AND BRAKES SQUEAL UPON BACKING OUT OF GARAGE AND SOMETIMES APPLYING WHEN STOPPING! SPECIFICALLY ASKED SALESMAN IF MERCEDES HAD PROBLEMS WITH BRAKES MAKING NOISE AS WE WENT THROUGH THIS WITH A VW TOUREG AND WAS TOLD NO THEY DO NOT HAVE THIS PROBLEM. CALLED SALESPERSON TODAY AND WAS INFORMED NOW THAT THEY ARE AWARE OF THIS ISSUE AND ITS NORMAL AND SHOULD ONLY HAPPEN WHEN CAR HAS BEEN SITTING AND ITS COLD OR THEY GOT WET. TOLD IF IT GOES MORE TIMES THAN THAT BRING INTO SERVICE???? VERY DISAPPOINTED WE WERE BOLD FACTLY LIED TO AND NOW HAVE ANOTHER CAR THAT APPEARS TO HAVE BRAKE NOISE ISSUES.

WHEN THE VEHICLE IS IN MOTION, OR STILL, THE DRIVER'S SIDE COVER FOR THE SEATBELT/AIRBAG WILL NOT STAY ATTACHED. THIS IS LOCATED ON THE DRIVER'S SEAT AND IS VISIBLE WHEN ENTERING AND EXITING THE CAR. I AM NOT REALLY CONCERNED ABOUT THE COSMETIC ISSUE AS MUCH AS THE SAFETY ISSUE. WITH THE SIDE IMPACT AIRBAGS, THIS IS A SAFETY HAZARD. IF THE BAG DEPLOYS WHO KNOWS WHAT WILL HAPPEN TO THE FLOATING PART? WILL THE AIRBAG, OR SEATBELT EVEN DEPLOY, OR WORK AS IT SHOULD? THIS IS ALSO A SAFETY ISSUE BECAUSE YOU CAN BE INJURED BY THE HARD PLASTIC THAT IS HANGING THERE. THE PIECE CAN ALSO GET CAUGHT UNDER OUR FEET WHILE DRIVING AS IT DOES NOT STAY IN PLACE. I REPORTED THIS THE 3RD DAY AND HAD IT REPAIRED 3 OTHER TIMES. I HAVE HAD MY CAR AND IT HAS BEEN IN PLACE ONLY 5 DAYS IN 2 YEARS, 2 MONTHS AND 30 DAYS. THE NEW LOANER THEY GAVE ME HAD THE SAME ISSUE AND THE PORTERS REPORT THEY NEVER STAY ON. THE CAR WAS IN FOR SERVICE FOR THIS ISSUE 4 TIMES IN THE FIRST 20 MONTHS I OWNED IT. IT COULD HAVE BEEN WEEKLY IF I WOULD HAVE NOT JUST LIVED WITH IT IN BETWEEN SERVICES THAT WERE NEEDED AND TAKEN IT IN AGAIN FOR SERVICE AND THE ISSUE.

VEHICLE SHUT OFF ON BUSY HIGHWAY. ENGINE SHUT OFF. ELECTRICAL/ COMPUTER SYSTEM MALFUNCITONED. VEHICLE WOULD NOT START BACK UP AGAIN
