Chevy Silverado and GMC Sierra battery cable may stall truck

NHTSA campaign 19V888000 · Reported 2019-12-12 · General Motors LLC

critical How serious is it? About this label

Serious: the engine can stall in traffic and the sparking can start a fire, so get it checked right away, though GM has not told owners to stop driving or park outside.

What's wrong, in plain English

Some 2019-2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks were built with too much glue on the ring at the end of the main positive battery cable. That glue can keep the cable from making solid contact with the alternator, the part that charges the battery while you drive. The connection can come and go, which can shut the engine off while you're driving. It can also spark, and the heat from that sparking can start a fire.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to confirm your truck is included.

Summary
General Motors LLC (GM) is recalling certain 2019-2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. 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.
Safety risk
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.
Remedy
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. All services will be performed free of charge. GM issued owners an interim notification on February 4, 2020. GM issued second notice and the recall began March 9, 2019. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-888-988-7267. GM's number for this recall is N192273510.
