Condition
If the K114B HPCM2 module is reprogrammed for any reason using normal Service
Programming on a 2019 model year Bolt EV, the vehicle will be limited to 90% state
of charge on the propulsion battery.
Vehicles not involved in the safety recall N202311730 will also have the 90% limit if
programmed.
Customers may complain that EV range was reduced if the state of charge is
unnecessarily limited.
Cause

part of the recall population. This is approximately 8,100 vehicles globally or 26% of
all 2019 Bolt EV.

If the 2019 VIN is not part of the recall, contact TechLine (TCSC) for programming instructions to program the
K1114B HPCM2 module without the 90% limit.
