Electrical issue
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.
Consequence

What the ratings mean
NHTSA gives the 2020 GMC Sierra 1500 4 out of 5 stars overall. NHTSA does not publish enough comparable results for this class and year to rank it against peers.
NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.
NHTSA's dynamic test put this vehicle's rollover probability at 19.8% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.
