Recreational Vehicle Lpg Tank Valve/gauge problems of the 2010 Chrysler Town & Country

While driving or stopped, the entire dash cluster flashes all the lights, the wipers randomly go on and off, the headlights go on and off, the gas gauge goes to "e", the tachometer goes to zero. This has happened several times and we have taken it in to our local chrystler dealership roughly 8 months ago only for them to say nothing is wrong. When it happened again, we took it to a local repair shop that said the same thing. This electrical fault won't show up on their "plug-in" analyzer. I have researched this for months and there are posts all over the internet from others who are having the same issue. There is even a video taken from someone while driving to prove this. I have called chrystler llc 3 times in the past 2 days. Finally today, a supervisor called me and said there is nothing wrong with my van and they won't do anything to assist. I also noticed a class action lawsuit from numerous states on this issue under tipm7. I have contacted a lawyer and plan to file a lawsuit myself since this $24k vehicle is not safe to drive. I will not allow my wife to drive it in fear her or our children may be injured. This issue have been identified since 2009 yet there is no recall? I am willing to bet they know about this unsafe issue but chose to do nothing. I would appreciate any assistance you may offer in this matter.
