What's wrong?
The battery positive, or B+, cable is the main power cable that connects the truck's charging system to the battery and electrical system. On 2019-2020 Sierra 1500 and Silverado 1500 trucks, the cable ring at the alternator is supposed to make a clean, tight metal-to-metal connection so charging current can move without interruption.
On affected trucks, excess glue was left on some B+ cable rings during supplier assembly. That glue contamination sits between the cable ring and the alternator connection, where heat from normal vehicle operation changes the joint. Over time, the connection loses clamping force and becomes intermittent, which interrupts the electrical connection between the alternator and the B+ cable.
Before failure, the driver can see a "Service Battery" or "Battery Saver" warning. Those warnings mean the truck has detected a charging or battery-power problem, and they match the warning signs tied to this recall.
Who's affected?

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific pickup truck is included.
What's the safety risk?
An intermittent connection at the alternator can stall the vehicle, increasing crash risk. Electrical arcing can generate enough heat to damage nearby material and increase fire risk. A "Service Battery" or "Battery Saver" warning is the sign to pull over safely and call the dealer. Repair is free at any franchised GMC dealer.
What should I do?
- Check your VIN to confirm your 2019-2020 GMC Sierra 1500 or Chevrolet Silverado 1500 is included in this recall.
- Contact a franchised GMC dealer to schedule the free B+ cable and alternator connection inspection that fixes the intermittent electrical connection.
- Bring the recall notice if you have it. If not, reference recall number 19V888 when you call.
- Drive cautiously until the repair is complete. If the truck stalls, smells hot, or shows electrical arcing damage, stop driving and ask the dealer about towing.
What happens at the repair
At the dealer, a GMC technician inspects the B+ cable attachment at the alternator for glue or other contamination. The technician cleans the connection and reattaches the B+ cable. If arcing damaged the cable, nut, or alternator, the dealer replaces the damaged parts. The recall repair is available now, and parts and labor are covered. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because the covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
