Official summary
A potential issue has been identified on a limited number of vehicles within the listed Affected Vehicle Range where the direct pressure sensing valve within the Air Conditioning (A/C) compressor becomes stuck and cannot respond to changing demands for A/C compressor displacement. The vehicle continues to operate; however, the function of the climate system is compromised by the failure mode. The customer may report a number of symptoms: cycling temperature within the passenger compartment, too cold, too hot, and/or odor ingress.
Vehicles covered
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.
