Hazard Flashing Warning Light Unit problems of the 2009 Dodge Journey

I was stationary in a parking lot. My vehicle has electrical problems when it gets below 50 degrees f. All of my dashboard warning lights come on and my gauges won't register including my fuel, rpm, and speedometer. My turn signals won't work and neither will my emergency hazard lights. My door locks and window controls work intermittently when this happens. My navigation screen/back-up camera will not work and my wiper blades and headlights stay on even though the controls are set to off. My wiper spray nozzles won't work and neither will my high beams. It will stay like this until my vehicle warms up, usually about 20-30 min. I am a nurse and often have to take call at night, so sometimes I don't have time to let it warm up. I have had to download an app that will tell me my speed and pray I don't get into an accident. I have taken it to the dealership multiple times and they can never find the culprit so it just wastes my time and money.
