2019 GMC Sierra 1500 Problems

The 17-inch spare tire that came with the vehicle does not match the accessory wheels, and under certain conditions this can stop the anti-lock brake system from working properly. A malfunctioning ABS raises the risk of a crash.

Fix: The dealer will replace the spare with a compatible 17-inch spare tire and wheel assembly, add a new spare tire label, and give you a manual insert on which spare to use, all free of charge.

The affected tires were cured for too long during production. Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.

Fix: Dealers inspect and replace the tires as necessary, free of charge, free of charge.

Fix: GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge.

The seat belt bracket for the front center seat may not be bolted securely to the seat frame. In a crash, the belt may fail to hold a passenger in that seat properly, raising the risk of injury.

Fix: The dealer will inspect both sides of the front center seat belt bracket attachments and reassemble them correctly if needed, free of charge.

One of the driveshaft joints may not have been properly welded, causing the driveshaft to separate while the vehicle is moving. If the driveshaft separates, there may be a loss of propulsion, increasing the risk of crash.

Fix: GM will notify owners, and dealers will replace the driveshaft, free of charge. The recall is expected to begin December 2020.

A software error in the brake control module can turn off electronic brake assist, so the car may not stop as quickly in an emergency. This loss of assistance raises the risk of a crash.

Fix: The dealer will reprogram the brake control module software at no charge.

A software error in the brake control module can turn off the electronic stability control and antilock brakes without any warning light. Drivers who don't know these systems are off face a higher risk of crashing.

Fix: The dealer will reprogram the brake control module free of charge.

The battery positive (B+) cable rings may have been manufactured with excessive glue, potentially causing an intermittent electrical connection between the B+ cable and alternator. An intermittent electrical connection between the B+ battery cable and the alternator could cause the vehicle to stall, increasing the risk of a crash. The intermittent connection could also lead to electrical arcing, which could generate sufficient heat to damage surrounding material, increasing the risk of a fire.

Fix: GM will notify owners, and dealers will inspect for the presence of glue or other contamination at the B+ cable attachment to the alternator and clean the connection and reattach the B+ cable connection, as necessary. If arcing has damaged the cable, nut, or alternator, the dealer will replace the damaged components.

When the front seat belt pretensioners fire in a crash, hot gas can escape through an opening in the bracket and may ignite the carpet. This could start a vehicle fire inside the car.

Fix: The dealer will seal the opening in the pretensioner bracket at no cost to you.

The passenger-side frontal air bag may have been damaged during assembly. In a crash, it might not inflate correctly, which raises the risk of injury.

Fix: Dealers will replace the passenger-side air bag module at no cost to you.
