I have had a 2014 Volt for two years now. It has been flawless. However, for all that time, when I have been driving it in a ranger of weather conditions, speeds, battery charge levels, new and old tires, oil changes etc. Some sort of alarm will chime 4 times while underway and there is never an accompanying text explanation on the display. I have the Volt version that has the backup camera and warning system but, unlike the Gen 2, I do not believe there was a side traffic monitoring system as an option in 2014. Any idea what the chimes are? It must be a built in feature but I have no idea what.
