Cars are usually given a high car rating by those participating in the automotive purchase side of things due to the car information provided that details what good things are in the vehicle as well as the capabilities it has on the road.
They are also valued basing on their aesthetics as well as – in more recent times – their protection of the environment in which they are being driven through adhering to emission standards as well as other forms of technology.
The Mercedes-Benz SL Class is a highly rated piece of machinery from the renowned German car maker. It checks all the boxes from performance to aesthetics and the company wanted to further satisfy the car market as relates to environmental friendliness. It is for this reason that a “greener” refrigerant was incorporated into the air conditioning system of the luxury convertible.
This new refrigerant, R1234yf, was tested and incorporated into the SL Class convertible. Further testing that uses more realistic situations has however cast doubt over the safety of the R1234yf. Apparently the refrigerant is at a high risk of igniting if the car is involved in a head on crash.
Mercedes has therefore recalled units that were manufactured between December 19, 2011 and May 31, 2012 so that the risky refrigerant can be replaced with the older R134a. The hoses will also be changed so that they are appropriate for the refrigerant.
