Recall Title:
Brake System Malfunction Warning

Recall Description:
General Motors has decided that certain 2019 model year Cadillac CT6, Chevrolet Silverado 1500, and GMC Sierra 1500 vehicles may fail to conform to S5.3 of Federal Motor Vehicle Safety Standard (FMVSS) No. 126, “Electronic stability control systems for light vehicles” and S5.5.1 of FMVSS 135, “Light vehicle brake systems.” In these vehicles, a software error can, in rare cases, disable the vehicle’s electronic stability control (ESC) and antilock brake system (ABS) systems for a single ignition cycle. If this specific error occurs, the vehicle’s diagnostics will not illuminate the vehicle’s ESC and ABS telltale lamps, as required by S5.3 of FMVSS 126 and S5.1 of FMVSS 135. If the driver is unaware that ESC and ABS are not functioning, there may be increased risk of a crash.
