GM Recalls More Than 900,000 Vehicles Worldwide Over Brake and Battery Issues

General Motors is recalling more than 900,000 vehicles across the globe to addresses issues from separate campaigns — one of which poses an always-exciting fire risk. On Thursday, the automaker announced a callback of more than 400,00 Chevrolet Silverado and GMC Sierra 1500 trucks from the 2019-2020 model years. The manufacturer is concerned that pickups’ battery positive cable rings may have been installed with excessive glue, creating a stalling risk, or in some instances a potential fire hazard.

Another 550,000 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 models from 2019 will also need to be recalled. A potential software issue related to the vehicles’ service brake system notifications could cause it to go haywire, negatively impacting their electronic stability control (ESC) and anti-lock braking (ABS) functions. 

According to Reuters, GM claims the vehicles’ diagnostic system will not illuminate the instrument cluster alert when the issue arises, but ABS and ESC will effectively be disabled until engineers reflash the software. The manufacturer believes the problem is exceedingly rare and should not affect most of the models under suspicion. GM issued a similarly large recall (roughly 638,000 vehicles) on slightly older trucks and SUVs earlier this year due to a faulty wheel-speed sensor. It also impacted braking and sent the vehicles’ software into error mode, providing an elevated crash risk at the same time.

Meanwhile, the glue-related recall only requires a visual inspection. From there, impacted components can be replaced with new rings installed using the appropriate amount of glue.

While no injuries are linked to the campaign, General Motors did cite one fire report. Details of the issue apparently emerged from the factory after a Canadian employee noticed the stalling issue. The manufacturer should begin notifying impacted owners before the end of next month.
