Official summary
Supersedes Technical Service Bulletin Group 87 number 15-61 dated April 23, 2015. The air conditioning does not cool, or the cooling performance is very weak. The air conditioning system cools, but the compressor is noisy. The noise is characterized as a grinding or groaning noise. Either symptom may be intermittent. No DTCs are stored. The condition may be caused by a faulty N280 valve. The internal components of the valve can be obstructed and incapable of full function. This loss of refrigerant regulation from N280 can cause noise from the A/C compressor and/or affect the HVAC cooling.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
