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.

    I don’t get the “glue” thing. Anyone? Bueller?

    ABS and ESC are a big deal and it looks like they are doing the right thing this time.

      So here is the deal, in a timely coincidence I read an article in a trade publication about trouble shooting a miss on a Chevy Captiva. After much testing it was determined that the bad sensor readings had to be due to a poor ground. Once he finally found where the computer’s ground terminals attached to the block he found that the adheasive lined heat shrink glue had run onto the area of terminal where the bolt clamped it to the block. The bolt was now loose since the glue squished some over time. With the terminal cleaned and the bolt properly torqued the sensor offset was gone as was the miss. Oh yeah the car occasionally stalled too.

      So my guess is there is something similar going on with this current recall.

    On my 1999 Silverado the parking brakes wouldn’t release fully and destroy the disc brakes. In 2000 they replaced the rears with drum brakes. They should of recalled mine, becuase it happened a second time.

    The ABS pump failed, the dealer said to pull the fuse if I didn’t want to pay the $1500 to repair it. I found a guy in Idaho who said the system was defective and for $500 he rebuilt hte pump and put in in software. Of course Chevy wouldn’t admit anything was wrong.

    Same old GM

    Glue? I thought the rings were either pressed/crimped or soldered in? Anyone in the know on this glue?

      Yeah, glue? They’re usually crimped. I replaced the (Chinese-made) negative cable on my daughter’s 2013 Cruze, because it experienced weird symptoms like EPAS (electric power assisted steering) errors popping up in the Driver Information Center, known to be caused by the defective cables. The terminals were not properly crimped, causing intermittent connection or resistance problems.

      How flammable is Chinesium, anyway?

      See above, my bet is the glue is from the adhesive lined heat shrink that is used to exclude moisture from the terminal to wire crimp.

    Wow this is terrible. Yet ANOTHER dangerous recall for GM. Quite the pitiful track record. Too bad its wasn’t a Ford recall eh? You’d have tons of clicks and comments by now.

    This is Barra’s GM. Profits are everything and quality and design must take a back seat. There is a reason Cadillac is ranked last in reliability.

    The good news is that if you disconnect the battery then you don’t have to worry about the brake issue.

    @Halftruth–Actually I knew about the terminals being glued on. I had a positive terminal on the battery of my 99 S-10 fall off when it was 2 years old. I took the battery into the dealership and they replaced it at no cost. You could see the remnants of the glue on the battery. The terminals were side terminals.
