RECALL - Automatic Exterior Lights May Not Activate As Required


NOTE- Canadian Trucks Only



N232431050-10: CMVSS Noncompliance Recall - Automatic Exterior Lights May Not Activate As Required - (Mar 26, 2024)


General Motors has decided that certain vehicles listed above may not conform to sections (19), (28), and (30)(c) of Canada Motor Vehicle Safety Standard (CMVSS) No. 108, “Lighting Systems and Reflective Devices”. The standard requires daytime running lights (DRLs) to be active if the vehicles are operated at the prescribed speed or have traveled the prescribed distance, unless lower beam headlamps are activated. Lower beam headlamps should automatically reactivate at a prescribed lux value during dark/night conditions. In these vehicles, both the DRLs and lower beam headlamps may not activate under the prescribed conditions when the manual lighting switch is in OFF or PARKING LAMP mode. During that time, the vehicle could be less visible, increasing the risk of a crash.


It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.

This is a phased launch.

The remedy is currently AVAILABLE for vehicles listed in the Make/Model/Model Year chart of the bulletin below.

The remedy is currently NOT AVAILABLE for the following Makes, Models and Model Years:

2020-2023 Cadillac CT4
