The complaint alleges that the air conditioning unit sold in certain GM vehicles is defective resulting in system failure during normal, everyday use. According to the complaint, two defects in the system cause refrigerant to leak out. The absence of refrigerant prevents the evaporator from becoming cold, causing the system to blow hot air into the car’s passenger compartment and, in some cases, causing other parts of the system to fail.
The first defective component is the line leading from the compressor to the condenser. This line consists primarily of an aluminum tube connected to a rubber hose. On information and belief, this line can fail in two ways. First, the aluminum tube can become disconnected from the rubber hose, creating an opening in the line that can allow refrigerant to escape. Second, the aluminum tube itself has a material defect that can allow the tube to rupture, also allowing refrigerant to escape.
The second defective component in the air conditioning system of the Class Vehicles is the condenser itself. On information and belief, the original condenser has a material defect that renders it unable to withstand the day-to-day normal operation of Class Vehicles. On information and belief this defect is most likely due to: (i) the use of an inadequate material to build the condenser, (ii) the use of an insufficient amount of material in the manufacture of the condenser and/or (iii) inadequate weld.
