Customer Satisfaction Program. Due to the industry-wide semiconductor shortage, the front heated/ventilated seats, front heated seats, or rear heated seats are not functional on certain 2022 model year vehicles listed above, built beginning November 15, 2021. The affected vehicle owners should have been made aware of the condition at sale, and notified that once parts are available, they would be eligible for a no additional cost retrofit to enable the feature.
Dealers are to replace the front seat heater control module, replace the front HVAC user interface control module and reprogram the body control module. In addition, Traverse vehicles will require the HVAC control module programming and some Silverado HD and Sierra HD vehicles may require replacement of the AM/FM stereo radio control.
