Air Bag Not Deploy problems of the 2016 Jeep Renegade

I believe there is a problem with the electrical system with this 2016 Jeep Renegade trailhawk which I bought new in 01/07/2017. These problems below happen at random times: driving city, highway, parked. Started around 1300 miles which was around 02/12/2017; last time I picked it up from the dealer was 06/30/2017 which they had it for 10 days. Freezing cluster, rear reverse camera staying on while in drive, alarm going on and off on its own. The main safety concern I have and have been back to the dealer three times in 6,000 miles with no solutions: is the alarms of �service electronic parking brake� alert going on which is 90% time paired up with �service airbag system� alert going on, and the seatbelt warning system flashing on. Sometimes it will clear itself, other times it will clear when I stop turn the car off, and then back on. Dealer says there is no errors in the system, and it didn't happen while they had the vehicle. July 5 still going on more frequently. I called dealer twice in the last five days and I have not received a call back. I do not feel safe in my vehicle, I have personally witnessed while working on a fire engine and ambulance that air bags sometimes do not get deployed for various reasons, and the out come is sometimes not good for the passengers. I have also seen that when air bags deploy properly it can save lives. I do not trust my vehicle for the safety of my family and I. I do have all documentation from the dealership. As well as video's on my iphone of this happening.
