Welcome to the forum @Balbright63. Sorry to hear about your issues with your PowerBoost. So when that light goes on with other Ford hybrids it means that "indicates Hybrid component fault/failure that will cause the vehicle to shutdown or fail to start." It could be a software issue from what other people have experienced with the Escape hybrid.
