MY 2016 MB GLE 350 WITH 57750 MILES STALLED IN THE DRIVE THRU LANE AT STARBUCKS. I WAS ABLE TO RESTART THE ENGINE. PARKED FOR APPROXIMATELY 15 MINUTES. NOTED THE CHECK ENGINE LIGHT ON. RE-STARTED THE ENGINE AND BEGAN TO DRIVE HOME. VECHICLE STALLED IN TRAFFIC AND COULD NOT BE RESTARTED. TOWED TO MB DEALER. THIS WAS THEIR ASSESSMENT: VERIFIED COMPLIANT. CONNECTED SDS AND RAN SHORT TEST. FOUND FAULT CODES FOR FUEL PUMP TO HAVE OPEN CIRCUIT & SHORT CIRCUIT. CHECKED POWER AT CONNECTOR TO FUEL PUMP TO FUEL PUMP CONTROL UNIT. NO PWM SIGNAL FOUND COMING FROM FUEL PUMP CONTROL UNIT. CHECKED FUEL PUMP CONTROL UNIT. FOUND FUEL PUMP CONTROL UNIT WET DUE TO WATER LEAKING INTO BACK OF VECH. PERFORMED WATER LEAK TEST. FOUND WATER SLOWLY LEAKING INSIDE OF REAR HATCH AT BOTTOM OF MIDDLE SECTION OF REAR HATCH. TO START RECOMMEND REPLACING REAR HATCH SEAL, RECHECKING TO SEE IF WATER LEAK HAS BEEN STOPPED THEN REPLACING FAULTY FUEL PUMP CONTROL MODULE (IF LEAK HAS BEEN CORRECTED INSIDE OF VECH AND WET ITEMS WILL NEED TO BE AIR DRIED) 4.50 HOURS LABOR. COST $1106.90 TOTAL. PLEASE NOTE THAT THERE ARE 5 OTHER SIMILIAR COMPLAINTS ON THIS WEBSITE FOR THE EXACT SCENARIO. WE WERE FORTUNATE THAT WE WERE EXITING A SHOPPING MALL ON A BUSY SATURDAY WHEN THE TRAFFIC WAS SLOW AND DESPITE THE LARGE NUMBERS OF VECHICLE SURROUNDING US WE WERE NOT INJURIED. I WOULD HATE TO THINK WHAT WOULD HAVE HAPPENED SHOULD THIS HAVE OCCURRED AT A HIGHER SPEED OR IF WE HAD CROSSED THE INTERSECTION. MAY HAVE BEEN DEADLY. PLEASE INVESTIGATE THIS SITUATION THOROUGHLY AS THERE WAS NO PRIOR WARNING OF ANY WATER OR MOISTURE ENTERING THE VECHICLE IN ANY FASHION. DON'T UNDERSTAND WHY SUCH A CRITICAL COMPONENT OF THE FUEL DELIVERY SYSTEM WOULD BE EXPOSED TO WATER OR MOISTURE SUCH THAT IT WOULD BECOME INCAPACITATED ABRUPTLY. PLEASE FOLLOW UP ON THIS CONCERN SO THAT OTHERS MAY NOT BE INJURIED.

OUR 2016 GLE350 WITH 67K MILES STALLED AT 5:45 P.M. ON A TWO LANE ROAD WITH HIGH TRAFFIC VOLUME. THERE WAS NO INDICATION BEFORE STALLING EXCEPT A RAPID LOSS OF POWER AND DOWNSHIFTING. IT WAS DUSK AND THE VEHICLE STALLED PARTIALLY IN LANE AS THERE WAS NO ROOM WITH WATER DRAINAGE DITCH. DEALER IDENTIFIED A SEAL IN THE LIFT GATE BEING DEFECTIVE ALLOWING WATER TO ACCUMULATE IN THE SPARE TIRE STORAGE AREA IN PROXIMITY TO THE FUEL PUMP. FUEL PUMP MALFUNCTIONED RESULTING IN VEHICLE STALLING. DEALER SHARED MERCEDES WOULD NOT ADDRESS NOR COVER THE $1600 COST TO REPAIR. WHAT VEHICLE ACCUMULATES ENOUGH WATER TO FILL A SPARE TIRE AREA AND IT OVERFLOWS SHORT OUT A NEARBY FUEL PUMP MODULE AND SOAKING THE INSULATION OF THE VEHICLE. VEHICLE IS GARAGED AND SERVICED AS DETERMINED BY THE ON BOARD COMPUTER. THIS IS A SERIOUS ISSUE IN THAT IF WE HAD BEEN ON A FREEWAY THERE IS NO WARING AND THE VEHICLE LOOSES POWER QUICKLY LEAVING NO ROOM TO MOVE OUT OF HARMS WAY.

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).

Complaint Creaking noise, in irregular sequence when driving slowly in combination with slight steering movements and/or Creaking/crackling noises from the area of the wheel bearing on the front axle when cornering/ maneuvering. Sound file attached for comparison. MUST match noise for proper diagnosis. NOTE: Steering functionality is not affected. Cause Contact area between wheel bearing and steering knuckle. See also: LI35.30-P-058566 (Throttle Lift-Off Noise - Rear) LI33.30-P-056665 (Throttle Lift-Off Noise - Front) LI40.10-P-059248 (Wheel cracking noise when cornering) Remedy 1. Perform Operation A and evaluate by testing vehicle. 2. If noise is still present after re-testing: • If 192/232 chassis, verify FIN is in the listed range below in "Operation B" and perform. • If not 192/232 chassis or vehicle is a 192/232 not in the listed FIN range, additional verifications of where the noise is coming from are needed. Use multiple channel NVH method to narrow down location. Verify the LI's listed above were completed or if there are other similar noises associated with the chassis (Example: 192/232 also has under panel noises and an associated LI). Operation A: 1. Clean contact surfaces of wheel bearing and steering knuckle with brake cleaner as seen in the attached pictures. NOTE: The front area of the wheel bearing and the seals must not come into contact with the cleaner, otherwise, the sealing rings will be damaged. 2. Clean threads of wheel bearing mounting. 3. Thinly coat contact surfaces of wheel bearing, steering knuckle, and axle mating face with Molykote (annular joint grease). See the attached steering knuckle and wheel hub pictures for reference. NOTE: Axle mating face greasing is also covered in LI35.30-P-058566 and LI33.30-P-056665. Operation B (Only applies to 192 and 232 in listed FIN range): Only affects vehicles up to FIN end number: • Model series 192: xxx xxx xx 002 876 • Model series 232: xxx xxx xx 022 312 1. Replace steering knuckle. 2. Wheel bearings do not need to be replaced.
