Mercedes-Benz is recalling 432 SL-Class roadsters from the 2013 model year because the air-conditioner refrigerant line could rupture in a severe frontal crash, according to the National Highway Traffic Safety Administration.
The recall affects SL vehicles that use R1234yf refrigerant and were built from Dec. 19, 2011, through May 31. (You can check your vehicle’s build date on a sticker on the driver-side doorjamb.) If the refrigerant escapes from the hose, the gas mixture could be released into the engine compartment and ignite a fire under specific conditions. Daimler, Mercedes’ parent company, discovered the problem during product testing, NHTSA says.
Mercedes will notify owners this month, and dealers will replace the R1234yf refrigerant with R134a and install new refrigerant lines. The service will be free. Owners can call Mercedes at 800-367-6372 or NHTSA’s vehicle safety hotline at 888-327-4236 for more info.
