GM recalls over 90,000 units including Chevrolet Silverado & GMC Sierra 1500

Date of recall: December 19, 2019

Vehicles affected

The first recall is for 2019 Cadillac CT6 sedans, 2019 Chevrolet Silverado trucks and 2019 GMC Sierra 1500 pickups, affecting 67,648 in total in Canada, plus another 464,000 in the United States. 

The second recall is also for the 2019-20 Silverado and Sierra 1500, though it is a separate issue affecting 24,289 vehicles. 

What’s the problem?

Affected vehicles under the first recall are susceptible to a software glitch that can disable the electronic stability control and anti-lock brake systems. When that happens, the vehicle’s diagnostic system also doesn’t light up an alert in the instrument cluster. With those functions disabled, there’s an increased risk of a collision. 

For the 2019-20 Silverado and Sierra 1500, the second issue is for the cable connecting the battery and alternator, which may have too much glue on it. If it does, it can interrupt the electrical connection, leading to a potential stall, or even a fire risk.

GM reported one fire incident in the U.S. but hasn’t noted any other accidents or injuries related to the defect. 

What’s the fix?

Dealers will reflash the software to patch the glitch affecting the stability control and brake systems. They can also inspect the cable for excess glue and either clean the connectors or replace the cable, if necessary.

What do you do?

GM will notify affected owners by mail with instructions on taking their vehicle to a dealer for repair.
