SSM 481352019-09-09. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some 2013-2020 vehicles equipped with an EVDC air conditioning (A/C) compressor may exhibit poor A/C performance/improper climate function. To support the proper diagnosis of this compressor, the EVDC control valve tester has been provided to each U.S. dealership (339-EVDC100). Ensure the A/C system has a full charge prior to any compressor diagnostics. To support the proper diagnosis of this compressor, the EVDC compressor tool must be used, and the results recorded in the Technician comments field with the warranty claim. This tester will help reduce the potential for misdiagnosis and unnecessary compressor replacement. Refer to the Rotunda catalog for a video and user manual which provide detailed operating instructions.
SSM 481302019-09-06. Service bulletin. VISIBILITY:GLASS, SIDE/REAR; VISIBILITY. Some 2010-2020 vehicles may exhibit distorted glass with a subtle orange peel pattern or streaking etched into the surface. This is caused by hydrofluoric acid which is used in some car wash solutions as a cleaning agent. Hydrofluoric acid can attack the glass and cause visual distortion and/or discoloration on the outer surface which cannot be removed by further cleaning. If this type of distortion is found, inspect the area of the glass that is covered by the cowl and/or molding. The portion of glass that is covered by the cowl or molding will not be affected by the acid. Hydrofluoric acid damage is not a defect in material or workmanship and is not a warrantable condition.
