Safety investigations
NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect.
Driver Air Bag Circuit High Resistance
Mercedes-Benz USA (MBUSA) has reported a high number of warranty claims for air bag warning lamp illumination due to a diagnostic fault code 9103 or 9123 indicating a high resistance in the driver's frontal air bag firing circuit.MBUSA's testing and evaluation have shown that this condition is the result of a faulty connector (specifically, improper wire crimp) but that it will not prevent proper deployment of the driver's frontal air bag.The faulty connector can cause the air bag circuit resistance levels to exceed the threshold that illuminates the air bag warning lamp, but they do not exceed a higher limit at which proper deployment of the air bag may no longer occur.The agency believes that further expenditure of agency resources does not appear to be warranted at this time.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.During the investigation, ODI learned that MBUSA will initiate a warranty extension program to address the faulty connectors in subject model year 2005 and 2006 E-Class and other MBUSA model/model year vehicles.This action will extend the warranty coverage for this issue to 10 years or 100,000 miles, whichever occurs first.MBUSA will notify all affected vehicle owners of this action.A bulletin describing this program is available in the investigative file.

IN JANUARY 2018, MY CAR HAD DEVELOPED SBC MALFUNCTION ISSUES AND I TOOK IT TO THE AND THEY QUOTED ME $ 2,700+/- TO FIX THE ISSUE. I THEN CALLED MB USA AND THEY TOLD ME THAT THE SBC UNIT WARRANTY WAS EXTENDED FOR 10YRS AND THAT I HAD JUST CROSSED THAT LIMIT. I THEN REACHED OUT TO A PRIVATE MECHANIC WHO AGREED TO REPLACE THE UNIT FOR $865 (PLEASE SEE THE ATTACHED RECEIPT). I WAS ABLE TO PURCHASE THE SBC UNIT FROM MB OF CLEAR LAKE FOR $1,045.70 . THUS, I WAS ABLE TO GET THE CAR REPAIR AND SAVE MY SELF ABOUT $1,000 AS MB WAS NOT COVERING ITS REPAIR. ON SEPTEMBER 2018 I RECEIVED A LETTER FROM MB USA, INDICATING THAT THE COST OF THE REPAIR IS REIMBURSABLE. I REACHED OUT TO THE DEALER AND PROVIDED ALL THE DOCUMENTS THAT THEY REQUESTED. HOWEVER, I WAS TOLD THE REPAIR CAN BE REIMBURSED ONLY IF IT WAS DONE BY AN AUTHORIZED DEALER. I BELIEVE THIS IS NOT A FAIRWAY TO RESOLVE THE ISSUE WHEN ALL THE RELEVANT DOCUMENTS ARE AVAILABLE FOR A LEGITIMATE REIMBURSABLE. MB I BELIEVE IS NOT ACTING IN GOOD FAITH AND I NEED YOUR ASSISTANCE IN RECOVERING MY DUE REFUND FOR A FAULTY SBC UNIT. I HAVE SENT A LETTER TO MB USA AND THEY REACHED OUT TO ME WITH THE ANSWER, "NOT UNLESS REPAIR DONE BY AN AUTHORIZED DEALER" THANK YOU.

MY AIRBAGS SELF DEPLOYED WHILE I WAS DRIVING. I HAD JUST LEFT WORK AND DRIVING NORTHBOUND ON THE WEST SAM HOUSTON TOLLWAY APPROACHING THE TOLL STATION AT HIGHWAY SPEEDS. THERE WAS AN INCREDIBLY LOUD EXPLOSION AND AND HARD PERCUSSION AS THE AIRBAGS SELF DEPLOYED WHILE I WAS DRIVING. I THOUGHT I HAD BEEN PUNCHED OR SHOT IN THE GUT. THE PASSENGER SIDE CURTAIN DROPPED DOWN AND THE RIGHT REAR PASSENGER SIDE DOOR BAG DEPLOYED. THE SEATBELT AROUND MY WAIST AND SHOULDER TIGHTENED. FORTUNATELY, I KEPT IT TOGETHER AND DROVE DIRECTLY TO THE DEALERSHIP. I HAD NOT HIT ANYTHING, RUN OVER A POTHOLE, SWERVED OR OTHERWISE MAKE ANY SUDDEN DIRECTION CHANGE. I WAS IMMEDIATELY CALLED BY AN OPERATOR ON THE MERCEDES EMERGENCY SYSTEM WITHIN THE CAR. SO MERCEDES IS AWARE OF THE INCIDENT AT THE TIME IT HAPPENED. SHE ASKED IF I NEEDED AN AMBULANCE OR POLICE. I TOLD HER THAT THE AIRBAGS HAD DEPLOYED ON THEIR OWN AND THAT I WAS PHYSICALLY OK. ADDITIONALLY, I DROVE IMMEDIATELY TO STAR MOTOR DEALERSHIP WHERE THEY LOOKED AT MY VEHICLE LESS THAN 20 MINUTES AFTER IT OCCURRED. THE SERVICE ADVISER AND SOME OF THE TECHNICIANS QUICKLY LOOKED AT THE VEHICLE (IT WAS NEAR CLOSING TIME). THEY SAID THEY COULD NOT READ THE CODES OTHER THAN THE SRS FAULT. I WAS ADVISED THAT IT WOULD LIKELY BE CHEAPER TO FIX AT A BODY SHOP THAN AT THE DEALER. I LATER FOUND THAT THE DRIVER SIDE REAR SEATBELT HAD ALSO DEPLOYED AND WAS TIGHTENED.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
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).
VISIBILITY/WIPER
Complaint There are several types of complaint about noises or poor windshield wiper wiping performance: A: Wiper blades squeaking, chattering, shuddering B: The windshield is not wiped completely (streaking) C: During the downward movement water is pulled back onto the windshield from the A-pillar (Figure 1) D: After windshield cleaning, water keeps spraying onto the windshield for several wipe cycles (Figure 2) A1: The windshield and wiper blades are contaminated with residues from car washing facilities, identifiable by the water beading. The resulting differences in the friction values between the wiper blades and the windshield can excite the wiper blades to vibrate. Note: It is mostly wax residue from the washer system, but also water-repellent nano-particle coating for paint and/or silicone-based washer fluid, that could cause this problem. A partially dry windshield also has different friction values, which can likewise result in squeaking of the wiper blades A2: The wiper blades are worn by mechanical damage (wiper lip damaged by ice or insect debris, or deformed by long periods of disuse). A3: Incorrect angle of incidence of the wiper arms to the windshield. Because of this, the rubber lip of the wiper blade may not flip over at the reversal point. Cause B: B1: Wax/ dirt residues on the windshield B2: Wiper blades deformed or worn B3: Downforce of wiper arm not OK (Figure 3) Cause C: Water is pulled back onto the windshield by the differential pressure created as the wiper arm moves downwards. Cause D: Washer water collects in the fastening of the wiper blade and is blown onto the windshield by the airstream over several wipe cycles. Note and supporting information: Wiper blades are wear parts which, even when "not used" for long periods (kept in park position), may become permanently deformed and damaged. Further stresses on the rubber wiper blade arise due to various environmental influences which progressively change the effectiveness of the rubber wiper blade and accelerate the aging process. Due to the natural aging process and wear, the wiper blades should be replaced twice a year, preferably in Spring and Fall (see operator's manual). Remedy Remedy A: A1: Cleaning entire windshield with A 000 986 40 71. A2: Checking water's flow behavior after windshield has been cleaned (see Video 1). If, after cleaning, there are still areas with water beading, then the cleaning process must be carried out again until a rejection reaction is no longer present. • Note: On the vehicle in the video (Video 1), water still beads on the bottom left of the windshield. The windshield is still not properly clean, even though it appears to be clean. The windshield is only properly clean when there are no more areas on the windshield where water beads. A3: Replace wiper blades with genuine wiper blades. Important: Only exchange wiper blades if windshield no longer has water-repellent areas Note: Replacement of wiper blades is not covered under warranty and can be replaced at the expense of the customer. Remedy B: B1: Clean windshield with intensive cleaner A 000 986 40 71. Important: Do not clean the wiper blades otherwise the graphite coating will be damaged. B2: Replace wiper blades with genuine wiper blades • Note: Replacement of wiper blades is not covered under warranty and can be replaced at the expense of the customer. B3: Check the wiper arm for excessive resistance in the bearing. Restore mobility or replace wiper arm if necessary. Remedy C: Problem inherent in design for which there is no technical remedy. Exception: X204 up to 02/2014. In these vehicles, it is possible to install the design configuration of vehicles as of 02/2014. This includes wiper arms (styled arms) with improved behavior in this respect. It is also necessary to replace the wiper blades because the styled arms feature a Top Lock connection (previously Side Lock).
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

Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamp/front fog lamp leaky or fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system • Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. • If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system • Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. • If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: Connect test adapter to pressure tester. (Figure 1) Check test adapter for leak tightness. To do so, connect plug and coupling (Figure 2) and apply a maximum overpressure of 30 mbar. • The pressure must remain constant. If the pressure does not remain constant, use a new adapter. Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (Figure 3). (Figure 4) • Make allowance for the different headlamp variants here (there are different outlet openings). Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. Plug the adapter onto the diagnostic socket on the headlamp housing. (Figure 5). Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. • If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is tight and there is natural physical condensation• If a higher pressure drop than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Desiccant packs can be installed for headlamps that are not leaky. Observe the following documents for installation of desiccant packs: • LI82.10-P-078302 Fogged headlamp, desiccant pack installed - open ventilation system • LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system

Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy Check for external damage: You can identify a damaged headlamp in the following way: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent, then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: External damage to the headlamp does not present a warranty or goodwill case. 1. Clear fogged/condensed LED headlamps and LED rear lamps: 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 and connect battery support via a charger. 3. Open the hood or trunk. 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). 7. If the condensation has disappeared, nothing else has to be done. Note: If defrosting has been performed, you can skip the first step. 2. Leak test of headlamp with overpressure: • Connect test adapter to pressure tester. (Figure 1) • Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. • All vents have to be sealed with sealing compound and the existing diaphragm with the stamp (picture 3 [3]). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). • Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. • Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). • Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged (picture 6). • If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is tight and there is natural physical condensation. • If a higher pressure drop than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. If the pressure test is not passed, the headlamp is leaky. If the cause cannot be rectified, the headlamp must be replaced. Note: If the headlamp is replaced, no dry packs may be installed on the new replacement headlamp. AR82.10-P-5455WT was created for the pressure test. **NOTE - As of Sept 2025 the pressure testing tool is not finalized and may require modifications to fit properly. This AR can be used as a reference manual for all closed headlamps. In the event of an open headlamp system, the vent ducts must be sealed before the pressure test.
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.
