An alarming problem

My 2025 E350 has 700 miles. Twice recently I've received emails from Mercedes Benz saying "The alarm in your vehicle has been triggered." Both times the car was fine with no sign of tampering. When I returned to the car, I didn't hear any audible alarm. Are there any adjustments for the alarm, should I take it for service, or just tolerate it?

Check the Guard 360 settings, although I think it is called something else for vehicles in the MBUSA market.

Where was your car parked when it did this? Could a vehicle with a really loud exhaust have triggered this? I had it happen to me one time where it detected an impact from a car passing not 5ft in front of the car with a crazy loud exhaust.
