Followup Notice - Our records indicate that an EMISSIONS RECALL has not been completed on this vehicle; refer to the address card for the affected VIN. On your 2018 Accord Hybrid, if an incorrect high voltage (HV) battery is installed the DTC P0A80 (Replace Hybrid Battery Pack) will be set. If the correct HV battery is subsequently installed, the DTC P0A80 cannot be cleared as required and may lead to a failed Inspection and Maintenance test. The new software version eliminates this issue.
