Recreational Vehicle Lpg Tank Valve/gauge problems of the 2005 Chevrolet Aveo

In addtition to the daytime headlights randomly shutting off, the clock in the center of the dashboard will disapear untill I turn on the headlights then it reapears. ~ just before the vehicle stalls just after starting in the morning here in the fla. Sun, all the gauges go up then back down. ~ this 2005 Chevrolet Aveo lt hatchback, is having more and more electrical problems but the dealer, rosner Chevrolet, refuses to fix the problem without a charge, since the vehicle is not a fire hazard or on a recall list. ~ I feel as though gm and the dealer, are hiding serious electrical issues from the buyer either due the cost of repairing the problem or due to some of the manufacturing being done in south korea. Or untill people start dying from these problems. ( or untill we start getting lawyers ).
