  I'm reporting a SERIOUS SAFETY ISSUE affecting all Mercedes-Benz R230 series SL roadsters, model years 2003–2012, of which approximately 85,000 were sold in the United States: • There are numerous reports on R230 SL owners' online forums that an electrical device located in the trunk of these…

  I'm reporting a SERIOUS SAFETY ISSUE affecting all Mercedes-Benz R230 series SL roadsters, model years 2003–2012, of which approximately 85,000 were sold in the United States: • There are numerous reports on R230 SL owners' online forums that an electrical device located in the trunk of these vehicles known as the BCM [Battery Control Module] is prone to CATASTROPHIC FAILURE and melt-down. • The failed BCM can subsequently CATCH FIRE – potentially destroying the vehicle and endangering lives and property nearby. See photos attached from one SL owner's experience. • MBUSA, its dealers, many SL owners, independent service centers and salvage yards are aware of this problem: multiple reports detailing it can easily be found on the Internet. Possible modifications to alleviate the danger have been affected by some SL owners, one picture of which has been uploaded here. • Mercedes-Benz is surely aware of the issue but has not recalled nor issued TSBs associated with this serious problem, nor has MBUSA acknowledged that vehicles modifications to alleviate the risk of failure and subsequent fires have been developed by owners and mechanics. • No symptoms are known to appear prior to melt-down, other than odors and/or smoke emanating from the SL's trunk. By then, it is TOO LATE. I respectfully request NHTSA open an investigation into this issue and require Mercedes-Benz address it by affecting modification or replacements of the faulty BCM system components in R230 vehicles.

  Complete brake failure while driving. No one was injured but the vehicle could not be stopped until the transmission went into limp mode with still no brakes. Now the ABS and SRS lights on. Brake pedal to the floor. I completely have new brakes speed sensors fluid exchanges and more. The current recall doesn’t seem to cover my vehicle. I contacted the dealership and they said there are no open recalls.

  This particular model 2009 Mercedes SL 550 hardtop convertible 5.5 liter motor has two batteries and accessory battery that battery that’s located in the trunk in the main starting battery that’s on the firewall. These batteries are both new in OEM recommended. If the car sits for 24 hours, it will not start. The electrical system is completely drained. There are many forms describing the same issue but yet the SL model is not included in a civil lawsuit. Mercedes-Benz definitely knows they have an issue in somehow it needs to be rectified.

• 11007974Complaint 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 "Headlamps or Front Fog Lamps Leaking or Fogged". 1. Prepare headlamp/check for external damage: 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: 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 (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. Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (picture 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. If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is not leaky and the problem is down to natural physical fogging. If a pressure drop of more 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. Note: Desiccant packs can be installed for headlamps that are not leaky. See: LI82.10-P-064766 Fogged headlamp, desiccant pack installed - open ventilation system LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system
• 11007753Complaint Headlamp or 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. Headlamps comply with all applicable standards. 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 and LED rear lamps: 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 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). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4F). 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 the formation of condensation, check the headlamp for a defect. (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. Remedy 2 A Damaged 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 in accordance with 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. With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. Open ventilation system: LI82.10-P-064766. Closed ventilation system LI82.10-P-078304
• 11005294Complaint Rear lamps fogged up/not leaktight. Cause Fogging of the rear lamps is a natural phenomenon, which can occur under certain climatic conditions. This does not lead to any technical impairment of the rear lamps. Remedy Rear lamp: Remedy 1: Clearing fogged/condensed rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4 F) Note: Do not wash the vehicle or subject it to high-pressure cleaning before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the trunk. 4. Switch on the exterior lighting. 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 (defogging progress).
