Battery & propulsion recalls (1)
General Motors, LLC is recalling certain 2026 Cadillac Escalade IQ, Escalade IQL, GMC Sierra EV, Chevrolet Silverado EV, and 2022 GMC Hummer EV Pickup vehicles. The high voltage battery may have an improperly secured internal module component.
Consequence: A loose component may move and damage the high voltage battery, increasing the risk of a fire.
Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. The rate divides those complaints by the electrified versions built, from the production counts makers report to NHTSA, and it is not adjusted for age. Death and injury figures count complaints that report one, not the number an owner typed in.
