NHTSA 20V-798 (December 2020) covers certain 2020 and 2021 Insights with the 2020 CR-V Hybrid and Accord Hybrid. The DC-DC converter in the power control unit can shut down in cold weather and stop recharging the 12-volt battery, which can end in a loss of drive power. Dealers update the power control unit software free of charge. No recall on this car names the high-voltage battery.
