Recreational Vehicle Lpg Tank Valve/gauge problems of the 2007 Jeep Commander

Upon starting the engine reads a high idle, drive the Jeep down the road and a red lightning bolt appears and then across the dash reads check gauges. At this point the coolant gauge quits working. If shut off and restarted the Jeep sometimes won't start and will say transmission overheating even when it's not. It will sound like the starter is stuck and keep trying to start until the key is removed. After about 20 minutes of it sitting it will now start and the gauges will work properly and no warning lights. Already replaced thermostat and temperature sensor.

All light flash off and on randomly sometimes leaving the gauges and ac not working then return and leave the eas and traction control light and check engine light on. Pulling the code reveal a u1403 and u1411 code. When bumps are hit or the ac is on the lights flash and sometime wiggling the ignition switch stops the flashing other times it is random and sometime more sporadic, when the vehicle is experiencing the problem the car ignition can be shut off and the restarted sometimes it stops the trouble. .

First my gauge cluster just goes crazy parked or even while driving it. Now I just drove it down the road and it is stuck in 4th gear will not go into any other gear!.

I was driving down the road and I noticed my back up assist lights flashing. Next thing I noticed was my rpm and mph gauges were moving together and bouncing between 0-30 mph. The turn signal on the car is intermittent while this is happening and the radio also is intermittent. This is happening at least once a day now. I've also had the vehicle shit off on me when coming to a stop. I'm not sure if this issue goes with the electrical issues that have popped up. I'm waiting for my part from the dealership for quite a while now.

This is the second time my vehicle has done this. The vehicle is working properly and then all of a sudden it will not start and I get multiple gauge notifications populate including check gauges, transmission over temp. This time it will not start at all, I have tried to start it every day multiple times and it will not start. The same messages are still populating, the battery is good, I have a brand new starter, there is fuel. The vehicle powers up, I can operate everything but the vehicle won't even try to turnover.
