About a month ago I had my 2018 G80 at the dealer to fix an overheating issue. It took a few weeks to get a radiator hose that was causing the problem. I just realized that the car alarm is not working either using the panic key on the remote or opening the car through a window with the alarm set. The horn works when I manually hit it on the steering wheel.
It is likely that the dealer somehow turned the alarm off. Is there a setting through the Nav screen to do this or does something have to be connected under the hood? Anybody aware of where the alarm connect to the horn?
