2024 GMC Sierra EV Service and Repair Manual

This factory service and repair manual for the 2024 GMC Sierra EV covers a truck offered in exactly one configuration: battery-electric drive, a four-door crew cab pickup body, and the Denali Edition 1 trim. With no engine variants to keep apart, the material stays on the drive system and the chassis and body built around it, with procedures, specifications, torque values, wiring diagrams and diagnostics grouped by system. Everything applies to that single build, which removes the guesswork of matching a procedure to a particular powertrain or cab.

Known issues on the 2024 Sierra EV. NHTSA carries three recalls against this truck. One concerns rear drive unit motors whose wires were not sufficiently insulated, so they can touch one another and cut drive power. Another involves front turn signals no brighter than the parking lights beside them, which makes a signaled turn hard for other drivers to read. The third covers a rear center seat belt anchor bolt that may not have been tightened properly. Six complaints are logged, on latches, brakes and the power train — systems documented here with their own procedures and torque values.
