2020 Chevrolet Bolt EV Service and Repair Manual
This factory service and repair manual for the 2020 Chevrolet Bolt EV is written for one four-door hatchback body, one battery-electric propulsion system and three trims: Base, LT and Premier. Because there is nothing to tune, time or fuel, the diagnostic weight shifts to the high-voltage pack, the drive unit, the charging hardware and the module network that supervises them, and the manual sets out the isolation, measurement and reassembly steps in the order they have to be performed.

Known issues on the 2020 Bolt EV. Eight recalls stand on the federal record. Three of them concern a high-voltage battery that can catch fire at or near full charge, two of those because the software meant to find defective modules did not install correctly. One covers a poorly cast front left brake caliper that can fracture under hard braking and lose fluid. Another has a seat belt assembly attached with the wrong bolts. Complaints total 172 and lean heavily electrical at 86, with 22 on steering and 11 on the power train.
