An assessment for loss of isolation in a rechargeable energy storage systems (RESS). The assessment may include collecting isolation resistance data for a plurality of RESSs operating onboard a fleet of vehicles, applying statistical methods and engineering rules to remove erroneous peaks and duplicate values from the isolation resistance data, generating one or more isolation rules based on the isolation resistance data to represent thresholds for determining whether a loss of isolation has occurred for the RESS associated therewith, and identifying an isolation issue type for the RESSs determined to have the loss of isolation.
