RepairPal Expert Overview:

These vehicles are equipped with a new type of A/C refrigerant - R1234yf. Testing has determined that escaping R1234yf refrigerant may ignite under specific conditions. A severe frontal crash may rupture one of the air conditioner refrigerant lines, which can result in a gaseous mixture of refrigerant being released into the engine compartment. The resulting fire could spread to additional combustible materials. Dealers will replace the R1234yf refrigerant with R134a (which is the type that had been used previously) along with new refrigerant lines (hoses) designed specifically for R134a.

RepairPal Expert Overview:

Transistors used in the front signal acquisition and actuation module (SAM-F) may have been damaged during module assembly. As a result, the module could fail without warning, increasing the risk of a crash. Dealers will inspect and replace the affected modules as necessary. This recall is scheduled to begin on May 2, 2008. The Mercedes-Benz recall number is 2008 030005.
