This bulletin has been revised to add certain 2022-2023 model year Buick
Envision to the population and update the Warranty Information section with the
labor time. Please discard all previous copies of bulletin N12354522-04.
Part availability for the 2022-2023 model year Buick Envision is still limited at
this time. However, a portion of the impacted VINs have been moved to an
Open status. The Open VINs are prioritized by cold weather region. It is
imperative that IVH is verified prior to performing repairs. We estimate the
remaining 2022-2023 model year Buick Envisions will be eligible in Q1 of
2023.

N212354522 retrofits vehicles that require parts and programming for the front
heated/ventilated seats or front-heated seats and rear-heated seats only.
Due to limited initial parts availability, dealers should not order parts included
in this field action for use as shelf stock. Parts should only be ordered when
the dealer has confirmed and validated the customer has a scheduled
appointment with the service department. Specific VINS will be required to
determine the correct part to order in the Electronic Parts Catalog (EPC).
The Heated Vented Seat retrofit will be executed under six separate bulletins
(N212354520 to N212354525). Please see chart below.
•
•
•
•

The six bulletins are separated by the parts and programming required
by trim level and model.
Based on parts availability, some of the six bulletins will launch in
phases by model.
Each VIN requiring a Heated Vented Seat retrofit will be included in one
of the six bulletins.
It is critical to verify the VIN in IVH to confirm the correct retrofit bulletin
is followed prior to ordering parts or performing repairs.

RPO

Description

Involved vehicles are marked “Open” on the Investigate Vehicle History screen in GM Global Warranty Management
system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections
and/or repairs.
Condition

Correction

Due to the industry-wide semiconductor shortage, the front heated/ventilated seats, front heated seats,
or rear heated seats are not functional on certain 2022-2023 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 and rear seat heater control modules, reprogram the body control module
and on some vehicles, reprogram the HVAC control module. Note: Some vehicles may also require an
additional retrofit of the Left and Right Front Seat Cushion Ventilation Blower in order to restore full
functionality of the ventilated seats. Vehicles built with this condition can be identified by RPO 04O. Use
IVH to verify if the vehicle is currently eligible in the Front Seat Cushion Vent Blowers Retrofit bulletin
N222378560. If so, both retrofits should be performed at the same time.

Yukon XL, customer appointments should not be scheduled until further notice.
Important: Due to limited initial parts availability, dealers should not order parts included in this field action for use as
shelf stock. Parts should only be ordered when the dealer has confirmed and validated the customer has a scheduled
appointment with the service department.
