Manufacturer: MERCEDES-BENZ USA, LLC. Report Receipt Date: OCT 01,

Component: EQUIPMENT:AIR CONDITIONER
Potential Number of Units Affected: 432
Mercedes-Benz is recalling certain model year 2013 SL-Class vehicles
manufactured from December 19, 2011, through May 31, 2012 originally
equipped with R1234yf refrigerant. Daimler AG (DAG), the parent
company of Mercedes-Benz, conducted product testing of a vehicle, not
sold in the US, but equipped with the same refrigerant. According to
Mercedes-Benz, the testing was designed to replicate worst-case
conditions expected in a severe frontal crash that would cause a
rupture of the air conditioner refrigerant line. A rupture of a
refrigerant line will result in a gaseous mixture of refrigerant being
released into the engine compartment.
The testing conducted by DAG determined that the escaping R1234yf
refrigerant may ignite under specific conditions. The resulting fire
could spread to additional combustible materials.
Mercedes-Benz will notify owners, and dealers will replace the R1234yf
refrigerant with R134a along with new refrigerant lines (hoses)
designed specifically for R134a. The remedy will be provided free of
charge. The safety recall is expected to begin during October 2012.
Owners may contact Mercedes-Benz at 1-800-367-6372.
