VEHICLE MALFUNCTIONED FOR THE 5TH TIME SINCE JUNE 2017 WHILE DRIVING ON THE SURFACE STREET. SUV COMPLETELY SHUT DOWN WHILE DRIVING, LOSS OF STEERING AND DASHBOARD ILLUMINATES EVERY WARNING SIGNAL INCLUDING A BEEPING SOUND; GEARS SHUT DOWN AND SUV COMPLETELY STOPS WAS DRIVING. IN LOOKING AT THE HISTORY (I'M THE 3RD OWNER), THE WORK PERFORMED FOR THE DEFECTIVE CAMSHAFT WAS COMPLETED 2 YEARS AFTER THE 2009 MERCEDES BULLETIN AND ANOTHER REPLACEMENT TO THE BALANCE SHAFT AND CAMSHAFT WAS PERFORMED 1 YEAR AFTER THE 2012 BULLETIN. IN ITS REPORT, MERCEDES ISSUED A CAUTION AND STATED, "NEW TIMING CHAIN TENSIONER MUST BE INSTALLED AND ONLY AFTER THE ENGINE HEAD COVERS (VALVE COVERS) ARE INSTALLED/BOTTLED ON. FAILURE TO OBSERVE THAT WILL RESULT IN THE OVER TIGHTENING THE TIMING CHAIN WHICH WILL ULTIMATELY LEAD TO ENGINE HEAD DAMAGE." IN THE CAR FAX REPORT, I SEE AFTER EACH REPAIR, THE OWNER SOLD THE VEHICLE. IN LOOKING AT MY RECEIPTS, I SEE MY REPORTS OF SMOKE FROM THE DASHBOARD (FIRE DEPARTMENT CAME TO MY VEHICLE WHILE IN ROUTE TO MY SON'S SCHOOL TO ENSURE MY SUV WOULD NOT CATCH FIRE). I ALSO SEE REQUESTS TO REPLACE LIGHT BULBS FOR BLOWN FUSE, THE BATTERY, WIRING ISSUE UNDER THE SEAT, NOW A NEW PROBLEM RELATED TO THE CAN TECHNOLOGY. ANOTHER RECEIPT WORK DONE ON THE CAMSHAFT. BASED ON MY RESEARCH, THE RECALL RELATES TO THE DEGRADING OF POOR MATERIALS USED TO MANUFACTURE THE 1ST GEN SUVS. I DON'T BELIEVE THERE ARE ANY REPORTED DEATHS BUT IT PUTS MANY PEOPLE AT RISK AS I WAS RESEARCHING THIS ISSUE LOOKING FOR MY RECEIPTS, I CAME ACROSS ANOTHER RECEIPT FOR THE ML500 2006 I SOLD BEFORE I PURCHASED MY CURRENT VEHICLE. THE RECEIPT SHOWS I WAS SEEKING SERVICE FOR THE ENGINE STOPPING WHILE DRIVING.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
SERVICE BRAKES
Complaint Repeat workshop visit for vehicle vibration while braking from 60MPH. NOTE: Although the symptom is similar to a tire or wheel vibration, it is usually readily noticeable that it is distinctly different if it happens at all times or only while braking. Cause Although the cause of the vibration is most likely due to excessive lateral runout on the rotor or hub/wheel bearing, the system as a whole needs to be checked for other possible contributors. 1. Prior collision damage. 2. Excessive vehicle sitting times without rotating components. 3. Wheel bearing/hub lateral runout. 4. Wheel mating interface has been overtightened (did not follow WIS torque procedures). 5. Mating interfaces have been excessively modified (painted, gouged, bent, etc...). Remedy Read through the entire attached worksheet prior to performing. After performing, please review the final page and perform work accordingly. NOTE: This document is not pre‑authorization or otherwise dealing with warranty. This is intended for diagnostic purposes only. If there are any questions on how to proceed OR The work sheet has been performed and the vehicle has returned with the same concern. Please perform the measurements as seen in the worksheet again and open a TIPS case to the Body, Chassis, and Entertainment team.
STRUCTURE:BODY
Complaint Clanking noise from the area of the speakers in the doors. Cause Under analysis. Remedy To narrow down the cause, first of all remove the door trim. • If the noise continues to occur even with the door trim removed, then continue the diagnosis working towards the speaker and if necessary, create a TIPS case with an informative video as an attachment. Note: Please refer to this document in the warranty claim and, once diagnosis is completed, select the damage code depending on the component part that is causing the issue. • If the noise stops when the door trim is removed, please proceed in accordance with LI72.10‑P‑067691. Information: In this case, do not use a damage code for the speakers in the warranty claim!

POWER TRAIN
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).
EXTERIOR LIGHTING
Complaint Headlamp, front fog lamp leaky or fogged. Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps: 1. Drive vehicle into workshop (temperature higher than +18 °C/+64.4 °F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing of fogged/condensed LED headlamps and LED rear lamps on electric vehicles: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). 2. Connect battery backup via a charger. 3. Open the front-end flap and ensure sufficient ventilation. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in condensation, check the headlamp for malfunctions. (see Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Note: Only implement Remedy 1 for model series 463 (from model year 2018) and model series 465. Remedy 2 A defective headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness according to LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. Note: With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. • Open ventilation system LI82.10-P-078302 • Closed ventilation system LI82.10-P-078304

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
