Okay I checked and it beeps way before any kind of sound...it beeps immediately after the windows go down and it keeps beeping if i don't let go of the button and it flashes (red light goes off as it beeps). I looked inside trunk again and noticed that the divider sits snug on the left side (where sensor is) and not as snug on right side (where sensor is not). Can someone please verify if there are two divider sensors? One on each side or only one on the left side. The right side seems like it could have had one yet it seems to be broken off...would warranty even cover it if its broken? I'm worried. Also when car was at dealer it was working...so it has to work somehow with just one sensor and the broken right side. Any suggestions?
