2024 GMC Sierra Service and Repair Manual
This factory service and repair manual for the 2024 GMC Sierra covers AT4, Denali, Denali Ultimate and Regular trims in crew cab and standard cab form. The engine list is short and familiar, the 325-cubic-inch 5.3L V8 and the 376-cubic-inch 6.2L V8, both gasoline, naturally aspirated and overhead-valve. Being a recent model year, most of what a shop needs from this truck is diagnostic, and the fault trees, wiring diagrams, torque values and specifications are organized with that in mind.

Known issues on the 2024 Sierra. Three recalls are on record for this year. One describes insufficiently insulated wiring in the rear drive unit motors, where wires touching each other can cost the truck its drive power. Another concerns front turn signals that are difficult for other road users to see, so the driver's intentions are not clear. The third covers a rear center seat belt anchorage bolt that may not have been tightened properly. Complaints are few so far, six in all, with single entries against latches and locks, the service brakes and the power train.
