Some units of the GMC Sierra pickup and GMC Yukon SUV may not activate their automatic headlamps in the appropriate lighting conditions. Now, a new recall has been issued to address this problem, which GM will fix through an over-the-air software update.
The Canadian government recently published several details concerning the new recall, including a description of the condition and what GM will do to fix it. The recall was initially issued on August 24th, 2023, and was last updated on August 28th, 2023. The manufacturer recall number is N232417190, while the Transport Canada Recall number is 2023-472.
The recall states that certain units of the GMC Sierra and GMC Yukon will fail to activate their automatic headlamps at the appropriate time as ambient lighting levels decrease. Canadian regulations require automatic headlamps to activate when ambient light levels drop below 1,000 lux, which is roughly equivalent to ambient lighting during an overcast day. For reference, an illumination level of 400 lux is roughly equivalent to sunrise or sunset on a clear day, while an illumination level of 0.05 to 0.3 lux is roughly equivalent to a clear night with a full moon.
The recall indicates that affected units include examples of the 2022, 2023, and 2024 GMC Sierra 1500; 2024 GMC Sierra HD; 2021, 2022, and 2023 GMC Yukon, and 2021, 2022, and 2023 GMC Yukon XL. Several other GM models are also included in the same recall, with a total of 163,611 units affected.
To address this issue, GM will release a wireless over-the-air software update to eligible vehicles, which will update the software on the body control module. As an alternative, customers with affected vehicles can also schedule an appointment with their local GMC dealer to perform the software update manually. GM will notify owners by mail.
Owners can contact GM Canada directly by calling 1-800-263-3777, or use the GM Canada recall and warranty website to determine if this recall applies to their particular vehicle.
