Please refer to the Part 573 report for specific vehicle model details. The software design of the communication module may fail to communicate the correct vehicle location for the emergency call system (eCall) in the event of a crash.

Risk. Failure of the eCall system may result in emergency responders being dispatched to the wrong location, increasing the risk of injury following a crash.

Remedy. MBUSA will notify owners, and the communication module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. The recall began March 12, 2021. Owners may contact MBUSA customer service at 1-877-762-8267. MBUSA's number for this recall is 2021020025.

The rear brake caliper pistons on these vehicles may not have been correctly coated, causing gas to become temporarily released into the rear brake hydraulic circuit, reducing braking performance.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 206, "Door Locks and Door Retention Components."

Risk. If the door appears to be locked, the door may be unintentionally opened, increasing the risk of injury.

Remedy. MBUSA will notify owners, and dealers will inspect the left rear door lock, replacing it as necessary, free of charge. The recall is expected to begin in January 2018. Owners may contact MBUSA customer service at 1-877-496-3691.

SEATBELT HAD TIGHTENED AND NOT RELEASED WHEN MY BODY MOVES. BRAKES ARE NOT APPLIED. TYPICALLY DURING DRIVING I'M SMALL ENOUGH TO MANEUVER MY HAND DOWN TO RELEASE RED SEAT BELT BUTTON. *TR I'VE HAD TO STOP MY VEHICLE 5-10 TIMES TO RELEASE BELT. I HAVE 2 SMALL KIDS 7/ 11 BOTH ARE 60 POUNDS THEY ARE 4 FEET TALL AND 4'6' 7 YEAR OLD STILL USES BOOSTER I''VE CHECKED BELTS TO THE BEST OF MY ABILITY BUT I'M 110 LBS 5'2' AND HAVE NO MECHANICAL TRAINING OR EXPERIENCE OR CERTIFICATIONS THIS HAS BEEN NOTED TO MERCEDES AND THE PROBLEM IS NEVER REALLY DISCUSSED. THE VEHICLE WAS OPERATING UNDER ALL CONDITIONS NOTED BELOW

I WAS DRIVING IN A RURAL AREA WHEN ALL OF A SUDDEN I HEARD WHAT SOUNDED LIKE AN EXPLOSION. MY FIRST INSTINCT WAS THAT I HAD BLOWN A TIRE BECAUSE IT WAS SO LOUD. HOWEVER, THE CAR WAS HANDLING FINE AND NO WARNING MESSAGES CAME ON. MY HUSBAND AND I BOTH SAID "WHAT WAS THAT?" EVERYTHING ON SEEMED FINE MECHANICALLY SO WE KEPT DRIVING, BUT A BIT SHAKEN BY THE SUDDEN LOUD NOISE. I FEW HOURS LATER WE STOPPED FOR GAS. AS MY HUSBAND WENT TO CLEAN THE WINDSHIELD HE NOTICED THE SHATTER OF THE GLASS ROOF PANEL. WE THOUGHT BACK TO THE INCIDENT EARLIER AND REALIZED THAT MUST HAVE BEEN THE SOUND ME HEARD. THE WEIRD THING WAS AT THE TIME NO ONE WAS AROUND US. NO CAR HAD BEEN IN FRONT OF US TO BE THROWING UP ROCKS. WE WERE ON A RURAL HIGHWAY. THE SPEED LIMIT ON THAT STRETCH OF ROAD WAS 80 MPH. THE TEMPERATURE OUTSIDE WAS APPROXIMATELY 65 DEGREES, SO NOT EXTREME. I TOOK THE CAR TO THE DEALERSHIP AND THEY SAID IT LOOKED IT SOMETHING HIT IT AT "THE SWEET SPOT" THAT CAUSED IT TO CRACK ALL THE WAY ACROSS AND THEN UP BOTH SIDES AND THEY REFUSED TO COVER IT. MIND YOU I ALREADY HAD TWO CHIPS IN MY WINDSHIELD FROM ROCKS FROM A GRAVEL TRUCK I WAS BEHIND A MONTH PRIOR AND THEY SOUNDED NOTHING LIKE THIS SOUND. THE WORRISOME PART WAS THAT THE SOUND WAS SO SHOCKING, IF I HAD BEEN DRIVING NEAR ANYONE IT MIGHT HAVE CAUSED AN ACCIDENT BECAUSE I WAS SO STARTLED AT THE TIME.

WHILE IN MOTION ON A HIGHWAY IN STOP AND GO TRAFFIC, CAR SHIFTED ITSELF FROM DRIVE TO NEUTRAL WITHOUT ANY DRIVER INPUT. ALL INDICATOR LIGHTS ON DASH TURNED ON. DRIVER UNABLE TO SHIFT FROM NEUTRAL BACK TO DRIVE TO REGAIN CONTROL OF VEHICLE. DRIVER COULD ONLY SHIFT TO PARK. DRIVER SHIFTED VEHICLE TO PARK AND TRIED TO SHIFT TO DRIVE, BUT WAS UNABLE TO DO SO. DRIVER TURNED OFF IGNITION AND RESTARTED CAR, AT WHICH POINT DRIVER WAS ABLE TO SHIFT THE VEHICLE INTO DRIVE. DRIVER REPORTS NO USER ERROR (I.E. DID NOT ACCIDENTALLY HIT THE SHIFTER, DID NOT HIT ENGINE ON/OFF BUTTON) AND NO INDICATOR LIGHTS WERE PRESENT PRIOR TO INCIDENT. VEHICLE WAS BRAND NEW: OWNED FOR APPROXIMATELY 10 DAYS WITH 199 MILES AT THE TIME OF ACCIDENT. VEHICLE HAD BEEN PURCHASED WITH 6 MILES ON ODOMETER.
