2013 Mercedes-Benz GL550

While driving on the highway approximately 70 mph the car stalled. I slowly came to a stop, unable to restart the car. After getting towed to a nearby Mercedes service shop, They diagnosed the issue as inaccurate fuel gauge and refueled the car. At the time the car stalled, the tank was approximately 1/8 full according to the gauge, but in fact the car stalled because it ran out of fuel. They were unable to pinpoint why they fuel gauge was showing the wrong level.

I WAS DRIVING FREEWAY 5N (12/20/12) ABOUT 200 MILES N OF LA WITH MY DISTRONIC PLUS SET FOR 79 MPH WHEN THE DISTRONIC QUIT CAUSING THE CAR TO SUDDENLY DECELERATE AND WITHOUT ANY WARNING. A CAR THAT WAS FOLLOWING (TOO) CLOSELY HAD TO BRAKE TO AVOID HITTING ME. I RECEIVED 3 ERROR MESSAGES SAYING DISTRONIC PLUS INOPERATIVE, ACTIVE LANE KEEPING ASSIST INOPERATIVE AND ACTIVE BLIND SPOT ASSIST INOPERATIVE. MY MANUAL HAS ERROR MESSAGES THAN CAN OCCUR BUT DID NOT SHOW THE ERROR MESSAGES I RECEIVED ON THE DASH READ-OUT. ON 1/9/13 THE DISTRONIC FAILED AGAIN IN THE SAME WAY WITH THE SAME MESSAGES. I TOOK THE CAR TO MERCEDES ON 1/17/13 FOR INSPECTION. THE DEALER FOUND "NO RELATED FAULT CODES PRESENT". I HAVE ASKED MERCEDES REPEATEDLY IF THIS IS SUPPOSED TO HAPPEN AND THEY WILL NOT ANSWER MY QUESTION. AND THEY HAVE NOT ANSWERED WHY MY ERROR MESSAGES ARE NOT SHOWN ANYWHERE IN THEIR MANUALS. ON A TEST DRIVE WITH A SERVICE TECH ON 3/21/13 THE DISTRONIC FAILED TO BRAKE THE VEHICLE WHEN THE VEHICLE CAME UPON A PARKED CAR AND ALSO A CAR IN THE DRIVING LANE. THIS HAPPENED 5 TIMES. THE SERVICE TECH SUPERVISOR DROVE THE CAR AND HAD THE EXACT EXPERIENCE. ON APRIL 4, 2013 I HAD AN APPOINTMENT TO HAVE MY CAR DRIVEN BY A FACTORY REP. THE MERCEDES FACTORY TECHNICAL SPECIALIST AND THE PENSKE SHOP SUPERVISOR DROVE AND TESTED MY CAR SEVERAL TIMES. THE VEHICLE DID NOT STOP OR SOUND A TONE WHEN COMING UP ON STOPPED VEHICLES OR CARS IN THE DRIVING LANE WHEN THE DISTRONIC PLUS WAS ACTIVATED WHICH IS NOT HOW IT IS DESIGNED TO WORK. NOT KNOWING THE CAUSE THE MB FST NOTED ON MY WORK ORDER OF APRIL 4, 2013: 5442 MB FTS TO REVIEW. I HAVE NOT HEARD BACK FROM MERCEDES ON THESE ISSUES OTHER THAN A BUY BACK OFFER THAT STATES THAT MY CLAIMS ARE "DOUBTFUL" WHICH IS SIMPLY NOT TRUE. THEIR RESPONSE IS IRRESPONSIBLE AND INSULTING. I WANT MY CAR FIXED SO IT IS SAFE TO DRIVE.

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).
