My 2016 with 45,000 miles is showing a check engine light with codes p1e00 and p1fc9: Hybrid/EV Battery Interface Control Module and Hybrid Powertrain Control Module. Dealer will look at it for $190. If it is warranty they will fix and charge the $190 to Chevy. If not under warranty the total repair will be on me. From what I can see these are warranty issues. Has anyone had these codes? Thanks.

Hybrid/EV Battery Interface Control Module 5 Cell Balancing Circuit


-----------
P1fc9 Chevrolet Description To maintain a similar state of charge on the cell groups, the hybrid/EV powertrain control module 2 looks at the cell group voltages and determines which cell groups need energy removed in order to maintain the battery groups at a similar state of charge. This is known as cell balancing. There is a transistor switched resistor wired in parallel with the cell group internal to the hybrid/EV battery interface control module portion of the battery energy control module. The hybrid/EV powertrain control module 2 sends a command to the hybrid/EV battery energy control module to begin cell balancing.
