  ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES

  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.

  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.

   Chafed or Broken Wiring Harness (Very Common) — This is the most frequent cause on newer GM vehicles. The factory wiring harness to the Mass Airflow (MAF) sensor is too short or secured with an overly tight zip tie. Engine movement causes the LIN bus wire to chafe and break internally near the connector.

   I have a severe safety concern regarding the auto shut off for this Chevy Silverado pick up. Several times I have almost gotten into an accident because while slowing briefly to stop before making a left, turn across traffic, the engine shuts off. When you press the gas, the engine starts back up, but the delay causes a safety concern with oncoming traffic. This feature should have a longer delay or be selectable to turn on.
