Transport Canada has issued a recall for the Chevy Silverado, Chevy Tahoe, and Chevy Suburban over an issue affecting these models’ automatic headlamps. The recall states that affected units may not activate their headlamps when ambient light levels reach a certain level. The recall was initially issued on Thursday, August 24th, 2023, and is tagged as Transport Canada Recall number 2023-472. The manufacturer recall number is tagged as N232417190.
Affected units include the 2022, 2023, and 2024 Chevy Silverado 1500; the 2024 Chevy Silverado HD; the 2021, 2022, and 2023 Chevy Suburban; and the 2021, 2022, and 2023 Chevy Tahoe. It’s estimated that this recall affects some 163,611 units, and includes several other GM models as well.
According to the recall, affected units may not activate the automatic headlamps soon enough as ambient light levels drop. Canadian vehicle regulations require that automatic headlamps activate when ambient lighting drops below 1,000 lux. A luminance level of 1,000 lux is roughly equivalent to available ambient lighting during an overcast day, while 400 lux is roughly equivalent to available ambient lighting at sunrise or sunset on a clear day. A luminance level of 0.05 to 0.3 lux is roughly equivalent to available ambient lighting on a clear night with a full moon.
Headlamps that fail to activate when ambient lighting levels drop below 1,000 lux may reduce visibility for the driver, thus increasing the risk of a crash.
General Motors will notify vehicles owners affected by this recall via mail and issue a wireless over-the-air software update to eligible vehicles that will update the vehicle’s body control module software. As an alternative, customers may schedule an appointment with their local GM dealer to update the system manually.
