The 2024 GMC Sierra has 3 recalls, the most serious being a defect in the rear electric drive unit where wire insulation can fail, causing contact between wires and a sudden loss of drive power.
The rear seatbelt anchor bolt may not have been tightened properly during assembly, meaning the belt can pull free from its mounting point in a crash and fail to restrain the occupant. There is also a lighting issue where the front turn signals and parking lights burn at nearly the same brightness, making it hard for other drivers and pedestrians to distinguish a turn signal activation from standard parking lights.
