This may be caused by an HVAC recirculation door linkage that has become
detached due to the actuator motor overdriving the recirculation door linkage
travel. Revised HVAC control module software has been developed to prevent
this concern by creating soft stops in the actuator operation preventing over
travel of the actuator arm. Update Prior to Sale UPS11517 (N143) has been
published to proactively update HVAC software prior to customer handover.
Customer owned vehicles will require an actuator arm replacement in addition to
the updated software. A Service Action will be published for Customer vehicles
when parts become available, target timing is mid February.
The (outside) ambient temperature reading displayed may be incorrect
compared to actual ambient temperature. This may be caused by an error in the
HVAC module software. Revised HVAC software has been created to correct
this concern. Update Prior to Sale UPS9317 (N131) has been launched to
proactively update HVAC software on certain unsold 18MY vehicles. TSB
LTB01119 has been published to address this concern for sold vehicle should a
Customer express a concern.
This may be caused by the Direct Pressure Sensing (DPS) valve within the air
conditioning compressor sticking and not respond to changing demands for air
conditioning compressor displacement. New HVAC software has been
developed to prevent the DPS valve from sticking. Service Action N151 is being
launched to proactively update the HVAC software in affected vehicles.
