Hi everyone, So for the past week I noticed that the message alert screen under the odometer will high light an alert but no longer makes a sound to alert me the only way i know of an alert is when i look and I see the display highlighted, Has anyone here had this problem before and is there away to fix it? It's not a big issue but I love the car and like to have everything optimum.Any suggestions would be greatly appreciated.

Thank You all in advance
