GM has issued a service bulletin for a ventilated seat blower motor retrofit for certain examples of the 2022 and 2023 model-year Cadillac XT4, CT4 and CT5.
The problem: affected units were built without ventilated seat blower motors, and can be identified by RPO code 04O.
The fix: certified GM technicians will be instructed to remove the non-functioning seat cushion ventilation blower with a functional unit. Some vehicles may also require the heated/ventilated seat retrofit performed beforehand. This program will be in effect until February 28th, 2026.
Affected components: ventilated seat blower motor.
Affected vehicles:
- 2022 and 2023 Buick Enclave
- 2022 and 2023 Cadillac CT4
- 2022 and 2023 Cadillac CT5
- 2022 and 2023 Cadillac XT4
- 2022 and 2023 Chevy Suburban
- 2022 and 2023 Chevy Traverse
- 2022 and 2023 GMC Acadia
Number of affected vehicles: it’s unclear at this time how many vehicles are affected by this issue.
Owners should: dealers are now contacting owners whose vehicles were affected by the ventilated seat blower motor constraint in order to receive a free retrofit.

It’s worth noting that select units of the Cadillac XT4, CT4 and CT5 currently have several other retrofits available. For the XT4, these retrofits include the heated front seats (RPO KA1) that are normally only available with the Cold Weather Package (RPO code Y19). In the meantime, the CT4 and CT5 models have their own retrofit for heated seats.
As a reminder, the Cadillac XT4 rides on the GM E2 platform, with production taking place at the GM Fairfax plant in Kansas City. Meanwhile, the two Caddy sedans utilize the GM Alpha 2 platform, while production for both vehicles takes place at the GM Lansing Grand River plant in Michigan.
