When operating the vehicle, the MBUX system will switch the User Profile without warning. When doing this it will reposition the driver seat for the new profile which causing interruption to the driver operating the vehicle. During the unexpected change the driver seat and the external mirrors will reposition to the switched User Profile. This has been reported to the Dealer (Mercedez Benz of Tampa) numerous times. The MBUX System was updated by the dealer Service Dept. (04 Jan - 10 Jan 2024) but has not resolved the problem. The dealer has been informed this presents a safety issue due to the unexpected User Profile switch and the changes to the driver's seat position and external mirror positions. Despite text messages to Service Technician and Sale Associate the reports has been ignored. There's no consistency or predictable method to know when the issue happens.
