GM is recalling 350,371 2019-2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks for an alternator wiring problem that may lead to a crash or fire.

GM reports that an intermittent electrical connection between the B+ battery cable and the alternator could cause the vehicle to stall, increasing the risk of a crash. GM further warns that the intermittent connection could also lead to electrical arcing which could generate sufficient heat to damage surrounding material, increasing the risk of a fire.

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. The recall is expected to begin January 27, 2020. 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.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
