Brake and Battery Issues Prompt GM to Recall Trucks

General Motors has recalled approximately 464,000 Cadillac CT6, Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, all 2019 model year vehicles.  GM has discovered that a software error can disable the electronic stability and antilock braking systems.  According to the National Highway Traffic Safety Administration (NHTSA), dealers are supposed start repairing recalled vehicles on January 27, 2020.  The repair will consist of reprogramming the antilock brake computer.  GM has also recalled 350,000 model years 2019 and 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 pickup trucks.  The problem with these vehicles is that the cable that goes from the battery to the alternator has too much glue in it.  As a result, the glue imposes a resistance to the flow of current and can cause the engine to stall, and possibly ignite.  This recall is also expected to begin on January 27, 2020.  Dealers are supposed to inspect the cables and clean the connections if necessary.  For additional information, owners can contact GM by visiting their website at www.gm.com, then scrolling to the bottom of the page and click on recalls.   Please have your vehicle identification number ready as you will be prompted to enter it to see if your vehicle is affected.
