General Motors (GM) has announced a recall for 55,755 of its 2023 Chevrolet Colorado and GMC Canyon vehicles due to a defect in the automatic emergency braking (AEB) system. This malfunction may cause the vehicles to stop or decelerate unexpectedly, posing an increased risk of collision.

The National Highway Traffic Safety Administration (NHTSA) has assigned Campaign Number 24V133000 to this recall, which focuses on the vehicles’ electrical system and forward collision avoidance components. The issue stems from the front camera module (FCM) system, which may incorrectly identify obstacles on the road, leading to unwarranted braking actions.

To address this concern, GM dealers will update the FCM software at no cost to owners. Vehicle owners are expected to receive notification letters starting April 8, 2024. For assistance, owners can contact GMC customer service at 1-800-462-8782 or Chevrolet customer service at 1-800-222-1020. GM’s internal recall number is A232424660.

Further assistance is available through the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or by visiting

The recall was prompted by a report submitted to GM’s Speak Up For Safety program on September 21, 2023, concerning similar issues in China. Subsequent investigations by GM and its supplier, Veoneer (now part of Magna), revealed that under certain conditions, the software in the FCM could improperly trigger the AEB system. This investigation identified 234 field complaints in the U.S., including four accidents and three minor injuries, between November 29, 2022, and February 6, 2024.

Remedy actions for the recalled vehicles involve reprogramming the FCM software to correct the defect. GM has confirmed that the updated FCM software calibration will prevent the occurrence of this issue in the future. Production models for the 2024 year have already been updated with the corrected FCM software.

Dealers were notified on February 22, 2024, with owner notifications to follow in April.
