If the relay shorts out, it could cause a fire in the engine compartment, even with the ignition off, which is a serious safety risk and could lead to injury.
Free Fix
Your dealer will replace the faulty relay with a new one at no cost to you. For now, please park your vehicle outside and away from any structures until the repair is done. You'll receive a notification with more information and should contact your dealer to schedule the repair.
