Due to the industry-wide semiconductor shortage, the front driver and passenger seat cushion ventilation blowers are not functional on certain 2022-2023 model year vehicles listed above, built beginning March 30, 2022. 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 non-functional seat cushion ventilation blower with a functional one. Note: Some vehicles may also require the Heated/Ventilated Seat retrofit which must be performed prior to completing this procedure.
