To:
All General Motors Dealers
We are pleased to announce that additional 2022-2023 model year Buick
Envision vehicles have been moved to Open status in IVH.
Part availability for the 2022-2023 model year Buick Envision is still limited at
this time. 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 by the end of
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.
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.
