2023 SUBARU WRX Service Brakes Problems

My vehicle has a hand brake built into the vehicle and at 25,000 miles my hand brake started to fail and wouldn’t hold the car in place. I had it repaired under warranty and the whole emergency/handbrake assembly was replaced, I looked at it and tested it before I left the dealership and noticed the same issue, I brought it up to the dealership and they noticed the same issue also after testing it again themselves, and they also stated there were other vehicles of the same model with less miles having the same issue and also said it could possibly be a recall. I drive a car with a manual transmission so the hand/emergency brake is what parks and holds the vehicle in place. I originally took it there because my handbrake was no longer holding my car in place to avoid hitting other vehicles especially being parked on...
