Elevated severity
This campaign addresses a defect NHTSA classifies as carrying elevated crash or injury risk.
What the defect is
General Motors, LLC (GM) is recalling certain 2024 Cadillac Lyriq, Chevrolet Blazer EV, Chevrolet Silverado EV, GMC Hummer EV SUV, and GMC Sierra EV vehicles. The electric motors in the rear drive units may have insufficiently insulated wires that can contact each other, resulting in a loss of drive power.
Why it matters
A loss of drive power increases the risk of a crash.
The remedy
Dealers will replace the rear drive unit, free of charge. Owner notification letters were mailed May 16, 2024. Owners may contact Chevrolet customer service at 1-800-222-1020; Cadillac customer service at 1-800-458-8006; Hummer customer service at 1-800-732-5493; or GMC customer service at 1-800-462-8782. GM's number for this recall is N242447080.
