Transport Canada recall 2023279 · manufacturer campaign N232403240

11 May 2023

Transport Canada lists: Equinox 2022–2023 · Terrain 2020–2023

What is wrong

The coating may be too thick on the connection bars for the lower universal anchorage system (UAS) for securing a child or booster seat in the rear seat. As a result, you may not be able to properly attach a child seat in the rear seat using the UAS.

Why it matters

A child seat that isn't properly attached could increase the risk of injury in a crash.

What the dealer will do

General Motors will notify owners by mail and advise you to take your vehicle to a dealership to inspect the bars for the lower universal anchorage system (UAS) in the rear seat. If necessary, the dealer will remove and replace the finish coating on lower anchorage bars. General Motors recommends to install child seats using the rear seat belts, as described in the vehicle owner's manual and child-seat manufacturer's installation guide, until the recall repairs have been completed.

What is wrong

On certain vehicles, the start-stop accumulator in the transmission may be missing bolts. As a result, transmission fluid could leak and eventually cause the transmission to stop working. If this happens, there could be a loss of power to the wheels.

Why it matters

A transmission fluid leak onto a hot surface can create the risk of a fire. Additionally, a loss of power to the wheels could increase the risk of a crash.

What the dealer will do

General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the transmission start-stop accumulator. It will be replaced if any bolts are found missing.
