General Motors is recalling 350,371 model year 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.
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.
What to do
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 free of charge.
The recall is expected to begin January 27, 2020.
Owners may contact Chevrolet customer service at (800) 222-1020 or GMC customer service at (888) 988-7267. GM's number for this recall is N192273510.
