Mercedes is recalling 432 SL-Class cars because of an issue it discovered during crash testing that could lead to a fire.
The units affected were manufactured between December 19, 2011 and May 31 2012 and use a specific kind of refrigerant used in the car’s air conditioning system that could catch fire after a severe frontal crash. Mercedes said the tests were designed to replicate worst-case conditions during a severe crash and found that the refrigerant lines might rupture during such a crash, allowing it to leak into the engine compartment.
If that happened, a gaseous mixture would be released and could ignite, causing a fire. Mercedes says it will replace the fluid and appropriate hoses containing it at no charge.
