2006 Mercedes-Benz SLK350

I was traveling on I20 going about 60mph. Car suddenly started fish tailing and thought I had a flat tire. Pulled over, no flats but back driver's side wheel was crooked. Had car towed to service center. Back frame is extremely rusted. My whole wheel could have come off which would have been extremely serious. My car only has 46000 miles and garage kept. No warning signs. I don't drive in wintry conditions. My car has only been inspected by the service mechanic and myself.

SEVERE JERK AS VEHICLE DECELERATED AROUND 10-12 MPH. TOOK VEHICLE TO DEALERSHIP AND TEST DROVE WITH TECHNICIAN WHO VERIFIED THE PROBLEM. THERE WERE NO WARNING LIGHTS OR CODES FOUND. I WAS NOTIFIED BY THE DEALERSHIP THAT THERE WAS A SNAP RING FAILURE WITHIN THE GEAR BOX. INVOICE INDICATES "RETAINING CLIP FAILURE INSIDE TRANSMISSION, VERIFIED SEVERE 3-2 DOWN SHIFT, SHORT TEST NO CODES.CHECK OF ADAPTATION DATA FOUND 3-2 DOWN SHIFT AT NEGATIVE LIMIT. REMOVED TRANSMISSION AND INSPECTED, FOUND B1 RETAINING CLIP FAILURE. REPLACE B1 AND B3 TENSIONING SPRINGS AND RETAINING CLIPS". MB CORPORATE WAS NOTIFIED WITH NO ASSISTANCE. I WAS APPALLED AT THE STATEMENTS MADE BY CUSTOMER COMPLAINT MANAGER WHO STATED "THE CAR HASN'T BEEN IN FOR SERVICE SINCE 2009", I RESPONDED BY SAYING THE VEHICLE WASN'T DUE FOR SERVICE UNTIL 26K MILES, MAINTENANCE IS DETERMINED BY MILEAGE, NOT YEARS, IF I'M CORRECT. SHE ALSO INDICATED THAT "RECALLS WERE ALWAYS VIN SPECIFIC" AND MY CAR WASN'T ONE OF THEM. I BELIEVE THERE'S A PROBLEM WITH THE TRANSMISSION THAT'S BEING CONCEALED BECAUSE MOST OF THE FAILURES ARE OCCURRING AT LOW MILES WHILE THE VEHICLES ARE STILL UNDER WARRANTY. MY VEHICLE WAS OUT OF WARRANTY DUE TO AGE BUT HADN'T TURNED 26K MILES YET. THE DIAGNOSIS WAS CLASSIFIED AS A FAILURE WHICH SHOULD HAVE BEEN TAKEN CARE OF BY THE MANUFACTURER. THERE NEEDS TO BE AN INVESTIGATION INTO HOW MANY REPAIRS HAVE BEEN MADE ON THE 7G TRANSMISSION. THERE IS A PROBLEM. *TR

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 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).

Complaint Potential corrosion on the rear axle carrier Cause Due to market-specific conditions such as moisture, ingress of dirt and/or environmental influences, corrosion can occur on the rear axle carrier Remedy In the event of a complaint, the optimized repair method must be used when replacing the rear axle carrier. The repair method for the respective model series can be found in the attachment. Repair packages are available in Xentry Repair Packages for the special processing of rear axle carriers Note: Please utilize flexible wand (319-SAT1058826) along with the Cavity Preservation Gun (W 000 588 03 72 00) for cavity wax application to improve coverage and reduces labor efforts. The flexible wand may be obtained through the Mercedes-Benz Standard Service Equipment Program website.

Complaint The sliding sunroof glass panel of the panoramic roof reverses during the closing process, either once or multiple times, without an entrapment (anti‑pinch) event being detected. The concern may occur temporarily or repeatedly during normal closing operation. Cause The automatic reversing function of the panoramic roof is overly sensitive due to parameterization in combination with seal counter‑pressure. This condition can cause the roof to reverse even though no obstruction is present. Remedy Retrofit the vehicle to meet Cleanpoint status “Panoramic sliding sunroof glass panel reverses during closing without a pinch event.” The retrofit includes: • Hardware modification (installation of a cover rail / EPDM lip) • Corresponding software update for the panoramic roof control unit The prescribed retrofit steps must be performed in the specified sequence as outlined in this document. 1) Retrofit the EPDM lip onto the rear edge of the panoramic sliding roof panel: • Clean the underside of the rear edge of the sliding sunroof panel (marking, Figure 1) (e.g., isopropanol). • Subsequently install the cover rail on the underside of the sliding sunroof panel (Figure 2). - Distance from the cover rail to the rear edge of the sliding sunroof panel A = 5 mm - Distance from the cover rail to the right and left edges of the sliding sunroof panel B = 9 mm - Apply firm pressure by hand along the entire bonding surface of the COVER RAIL - The wider flange at the ends of the cover rail (see Figure 3) must point in the direction of travel 2) Submit an XSS Ticket with the following requests to add SA code O75 to the Vehicle Data Card • Enter code "O75" (Oscar 75) in Vehicle Documentation System (Vedok): • Add the following AO text to KG 78: AO code O75 added as specified in LI77.21-P-075806 (Version 7). 3) Install new software from the panoramic roof control unit (TSSR296, A98, PSD) and teach in the anti-pinch protection again: • Connect XENTRY Diagnosis. - always use the current XENTRY Diagnosis software release with all available add-ons. - Strict compliance with the operation steps in XENTRY Diagnosis is absolutely essential! - Ensure adequate power supply to the vehicle's on-board electrical system battery (greater than 12.5 V) using a battery charger. • Commission the panoramic roof control unit - To do this, select "A98 – control module 'panoramic sliding sunroof' → adaptation → commissioning → Commission the control unit." - Then follow user guidance in XENTRY Diagnosis. • Disconnect XENTRY Diagnosis.

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
