Recreational Vehicle Lpg Tank Valve/gauge problems of the 2006 Jeep Grand Cherokee

Steering /electrical it start to malfunction the gauges act up steering seems to lock ,I pulled over on road sat in car for twenty minutes ,disconnected battery /reconnected then started car to get to destination ,so I only use vehicle for local use ,worried about safety factors on my car.

While pulling out of my driveway all my dash lights came on then everything went black. My speedometer and tachometer both dropped to 0 and my gas gauge dropped to empty. The vehicle continued to run and I did not lose any power but the all the dash lights continue to go off and on and the gauges will drop to 0 or empty while the car is in motion.

All warning lights came on and gauges shut down while driving on the highway. After getting off the highway, and it did it again then my vehicle completely shut down. I then restarted my car and the check engine light stayed on. I have filed a complaint in 2013 with your department and with Chrysler. I again talked to Chrysler today and they are telling me there's noting they can do to fix it at this time, because they don't have the parts available. I'm afraid that this can lead to a bigger problem if it shuts down while on the highway. What can I do to get this resolved?.

Random incidents while driving the dashboard will light up with all indicators and gauges go to zero value. I recorded on my cell phone one incident. I had one case that Jeep stalled at same time of incident, and I was able to coast to side of road, shut engine off and restart. I discussed this with local dealer and they could not obtain any error code. I called Chrysler on one incident and they said they had no known problems reported on my vehicle. Dealer said to return next time it happens but I am always not in a convenient place and the dashboard will return to normal status after some time while driving.

When driving all the dashboard warning light come on (flicker) and interior dome lights go dark. The heater dies and the gauges do not work (shows 0 rpm and gas tank as empty). I am unable to even read my speed at what I am driving. It happens numerous times there is no certain times when it happens, I can be at a complete stop, in park , or driving at any rate of speed. The warning light flash anywhere for 1 to 30 times. I can still drive but have no power for anywhere from a sec to 5 seconds. This has been going on for over a year. I went at the longest of 3 months with out it occurring. Now in the past month it is doing it every time I start the car and continues until I reach my destination. I have taken it to shop to be diagnosed and they say it is due to the ignition switch recall. Then they proceed to tell that the parts with Chrysler are not available and they are unable to fix this problem. I am very upset, I am very scared to drive my vehicle. I feel this is a safety issue and should be fixed ASAP. I hope this does not cause an accident when I or anyone else could possibly be harmed.
