Over 1.1 Million GM Vehicles, Including EVs, Under NHTSA Investigation
Probe centers on potential brake system defect tied to 46 complaints and three reported injuries.
NHTSA has opened a defect investigation into GM vehicles following 46 owner complaints of reduced or delayed braking response, with three injury reports allegedly linked to the issue.
What Happened
The investigation, designated PE24-017 by NHTSA's Office of Defects Investigation, covers more than 1.1 million model years 2020 through 2024 across multiple GM nameplates including the Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac CT4 and CT5, and the Chevrolet Bolt EV. The complaints center on brake system performance issues in which drivers reported reduced or delayed braking response. NHTSA has received three injury reports allegedly linked to the defect, though a causal connection has not yet been established.
Why It Matters
The scale of this investigation puts roughly 1.1 million vehicles potentially in scope for a safety-related recall, should regulators determine a defect exists and mandate a fix. For Bolt EV owners specifically, the inclusion means battery-electric vehicles face the same regulatory scrutiny as GM's conventional powertrain lineup. A brake system failure represents a critical safety concern regardless of drivetrain type, and resolution could involve software recalibration, parts replacement, or both.
The Bottom Line
This investigation is in its early stages—opening a probe does not guarantee a recall will follow. Affected GM owners should monitor NHTSA's recall database and await official communications from the automaker regarding any required service actions.
