Electrical system:12v/24v/48v battery:cables
Problem: 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.
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.
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. 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.
