Most of the codes referring to voltage to high and voltage to low. The entire truck is shutting down electrically and we can only assume that this will result in one of two options. First is that the vehicle will catch fire because of the system wide known wire chafing electrical issues. Second is that the vehicle is totaled / junked since chevy will neither recall the known issues and is too busy changing customers for fraudulent repairs that their vehicles do not need. Take for example p0307 which chevy wanted $165 for the diagnostic fee and over $650 to replace cylinder 7 injector along with time for the repairs (over $1,000) for a $14 known wire connector issue that chevy is performing fraudulently. Chevy cannot continue to lock the center information screen. That information is vital to our driving.
