I HAVE BEEN ISSUED A STOP DRIVE ORDER UNDER RECALL ID# 22V315. I HAVE CONTACTED MERCEDES BENZ TWICE AND BEEN IGNORED TWICE. FIRST CALL WAS AROUND JULY 5TH-2022 AND SECOND CALL WAS ON JULY 12TH. THEY APPARENTLY DO NOT CARE ABOUT YOUR STOP DRIVE NOTICE AS NO ONE HAS GOTTEN BACK TO ME ON THIS ISSUE.
This is relative to the brake booster recall. Mercedes-Benz conducted a test and there was significant corrosion that exceeded the normal limits allowed. I am still under a stop drive order but I have not been provided any further instruction or provided a vehicle to drive while my vehicle awaits repair or buy back.Customer service representatives have not corresponded with me despite multiple emails and calls over the last 2 -3 weeks. I need A vehicle repaired so it can operate safely or I need another vehicle to drive while awaiting available parts please.

"TAKATA RECALL" MY 2012 GL 450 MERCEDES BENZ ABS WARNING LIGHT CAME ON WHILE DRIVING IN THE CITY. WHILE DRIVING AT ABOUT 45 MILES PER HOUR THE BRAKES ENGAGED BEFORE I COULD STOP MY VEHICLE AND PULL OVER. IT LITERALLY ALMOST SENT ME THROUGH THE WINDSHIELD, A HARD GRINDING SOUND AND AN INTENSE STOP. STILL TRYING TO GET OUT OF THE WAY OF TRAFFIC THE VEHICLE JERKED AND JERKED AND THE BRAKES CONTINUED TO ENGAGE. THIS WAS VERY DANGEROUS AND COULD HAVE CAUSED A SERIOUS ACCIDENT. THIS IS VERY DANGEROUS. IF THE ABS SYSTEM IS FAULTY OR A BAD SENSOR THEN IT SHOULD NOT ENGAGE ITSELF AT ALL. I CALLED THE LOCAL MERCEDES DEALER AND SPOKE WITH A SPECIALIST AND HE INFORMED ME THAT YES THE BRAKES WILL ENGAGE IF THERE IS AN ISSUE WITH THE ABS. AGAIN THIS IS VERY DANGEROUS AND A RECALL SHOULD BE ON THE SENSORS WHETHER IT'S THE ABS SENSORS OR THE SPEED SENSOR WHICH THEY ALSO INFORMED US THAT COULD CAUSE THIS MALFUNCTION. REGARDLESS THE VEHICLE BRAKES SHOULD NOT ENGAGE WHILE DRIVING.
HELLO, I WOULD LIKE TO NOTIFY A DEFECT ON A VEHICLE MERCEDES GL 500 MODEL SERIES X166 MADE IN 2012 IN U.S. PLANT BY MERCEDES COMPANY IN SEATTLE. WHILE DRIVING THERE WAS A FAULT IN THE BRAKING SYSTEM WITHOUT ANY WARNING LIGHTS. DURING THE BRAKING THE BRAKE WAS PUSHED TO THE FLOOR, BUT THE VEHICLE WAS NOT STOPPING. IN THE CASE IF THE VEHICLE WAS DRIVEN BY AN INEXPERIENCED DRIVER, IT IS MORE THAN CERTAIN THERE WOULD HAVE BEEN AN ACCIDENT. THE VEHICLE IS CURRENTLY LOCATED AT AN AUTHORIZED MERCEDES SERVICE IN TRENCIN (SLOVAKIA) AND HEADQUARTERS COMPANY DOES NOT APPEAR INTERESTED IN RESOLVING THIS SERIOUS SECURITY DEFECT. THEREFORE, THE VEHICLE WAS MANUFACTURED IN AMERICA AND MOSTLY IS SOLD IN THE U.S. MARKET; I GIVE THIS FACT TO YOUR ATTENTION WITH THE RECOMMENDATION TO INVESTIGATE THE TECHNICAL CONDITION OF THESE VEHICLES.
