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.

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.
