DETROIT (AP) – General Motors is recalling about 162,000 full-size pickup trucks worldwide for a second time because of faulty brake control software that was installed in a recall from last year.

Affected are Chevrolet Silverado and GMC Sierra light-duty trucks from the 2019 model year. The Silverado is GM’s most popular U.S. vehicle.

The saga began in December when GM announced it would recall about 550,000 pickups and Cadillac CT6 sedans globally to fix a software error that can disable the electronic stability control and antilock brakes. If those features don’t work, it can increase the risk of a crash.

The new software was installed in about 162,000 vehicles, but GM started getting reports that it was causing other problems, according to documents GM filed with the U.S. National Highway Traffic Safety Administration.

If the vehicles are started remotely using a GM mobile phone app or the driver gets in the vehicle and waits five or more minutes before starting it, the software could disable the electronic power brake assist system and turn on several dashboard warning lights, the documents said.
