It's happened four times in two weeks. Three left hand turns and one right hander... passenger seat occupied on right hander, all turns were while in motion and without breaks being applied, not sharp turns..no dashboard warning lights accompany the set of two - two beeps each, total of four beeps. Sound doesn't match the seat belt warning.... it's very obvious, loud enough to startle my passenger... Going to dealer on Wednesday for install they owe, I'll check with them... any thoughts?
