Risk: Wheel lock-up while driving increases the risk of a crash.

The daytime running lights (DRLs) may not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: DRLs that do not deactivate as intended may result in a glare, reducing visibility, and increasing the risk of a crash.
Fix: The body control module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. Owner notification letters were mailed January 23, 2023. Owners may contact GMC customer service at 1-888-988-7267, Chevrolet customer service at 1-800-222-1020, or Cadillac customer service at 1-800-458-8006. GM's number for this recall is N222386380.

Recall 21V-611: Air Bags
Problem: General Motors, LLC. (GM) is recalling certain 2020-2022 Cadillac CT4 and CT5 vehicles. The roof rail side-curtain air bags may not have been installed correctly, which could result in an improper air bag deployment during a crash.
Risk: Air bags that do not deploy properly can increase the risk of injury in a crash.
Fix: Dealers will inspect both left and right-side roof rail air bags and reinstall the air bags, as necessary, free of charge. Owner notification letters were mailed on August 30, 2021. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is N212342780.

Problem: General Motors LLC (GM) is recalling certain 2020 Chevrolet Corvette and Cadillac CT4, CT5 and XT4, 2021 Chevrolet Trailblazer, and 2020-2021 Buick Encore GX vehicles. Sensor connection contamination in the electronic brake boost system may cause an interruption of communication between the sensor and the brake boost system.
Risk: If communication with the sensor is interrupted, the electronic brake boost assist could be lost. Extra pedal force will be required to slow and stop the vehicle, increasing the risk of a crash.
Fix: GM will notify owners, and dealers will replace the electronic brake boost module, free of charge. The recall began December 9, 2020.
