When it sees CPU pressure, it adds pods. This works great until the thing causing your CPU pressure isn’t your service being overwhelmed, it’s your service being blocked waiting on something else. I’ve been on-call for incidents where the database connection pool saturated. Application pods queued up waiting for connections. The HPA saw CPU pressure and fired more pods. The new pods each opened a handful of database connections.
