Violating the Consistency Rule will not cause you to fail your account. However:
Your profit target will be adjusted (if you're on a challenge account)
Your trading period will be extended until you either meet the required consistency or fall below the limit.
You cannot pass the challenge if your consistency percentage remains above the allowed threshold.
In short, you’ll still be able to continue trading, but you won’t progress to a funded account until your trading results comply with the rule.
