The 2026 GMC Sierra EV has 2 recalls, both centered on the same issue: the electronic stability control warning light can fail to illuminate when the system has a fault, leaving the driver unaware that stability control may not be functioning.
When the stability control system develops a problem, the dashboard warning light is supposed to alert the driver on the next startup. In affected vehicles, that light may stay dark even with an active fault, meaning the driver could operate the truck without knowing the system that helps prevent skids and loss of control is compromised.
