Repeated false alarm activations. At a recent dealer service I asked for a star readout. I was told it had logged 10 events broken rear/ back windows.
Apparently the alarm monitors the glass in case it’s broken. As there’s no damage they suggested a broken/ damaged wire to the tailgate. They suggested the head lining would have to come out and it would be a long job. I asked could it be coded out. To be told no. Can anyone help with a fix or workaround?
