Mercedes-Benz 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.
The short version
MERCEDES-BENZ USA, LLC. reported a problem with the appliance air conditioner. Here is what owners need to know.
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.
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, free of charge.
