Happy New Year to all.
I am looking for any information on how to fix the alarm system from going off randomly. I have taken it to a Chrysler dealership, they had it 4 weeks, and they told me to take it to Mercedes, which they have had it 2 weeks an nothing yet. I know the problem is common via the internet but haven't seen any answers to the problem. HELP.

Probably the batteries going bad in the alarm module.
You can unplug and remove it and the car will be fine until you get a replacement.
It is located in the center under the wiper cowl.
