This does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q3 2025. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available.
