alarm going off with severe thunder. Is there a way to dial down the sensitivity

Hello, sounds like you have an added on aftermarket alarm that has shock sensitivity -- so yes, most of those alarms have an adjustment. However, they are all different, and not supported by Jeep -- so I couldn't tell you where to look or what to do. You could check for whoever sold the vehicle -- they may have resources, or a local shop near you could certainly figure it out.
