Recreational Vehicle Lpg Tank Valve/gauge problems of the 2007 Chevrolet Cobalt

It starting having flashing dashboard lights once as I was driving it just a few blocks from my home the first time it happened all gauges go everywhere up down or stop it looks like a christmas tree! and before the gear shift had some clicking at times. The clicking started then the gauges started going all over and the speed was all over then dropped to 0 not to move again. It's been happening on and off for about 8 years but as time goes on it's getting really bad I've kept looking for recalls as did my mother as she had the car before my owning it. It now does this anytime and the steering stops working with no notice or if it's not working and trying to pull over as it did on an on-ramp it kicked on and made the car jump into side lane about half way into that lane. Had it been a two lane road and a car coming towards me it would have been a dead head head on collision as it takes time and a lot of power to move the car when the steering is like a 1950 tractor in a wet field! I have back issues and don't have the upper arm strength that it really needs. There in no real warning when it's going to happen. But sometimes I hear a click and it happens a few seconds later. Also the interior lights every one through inside of the car stopped working about 3 months when my parents bought the car used back in June 08 they have never worked since. It had like 23,000 miles on it roughly. They was in middle 60s back then. It's now a family car and it's scary to have to drive it but I've got money in it I can't afford a replacement now. I have video of what it does. I just have videos no pictures.

Cobalt will randomly display car lock symbol and check engine light on the dash. The gauges on the dash (speedometer, gas, etc. ) begin to flash back and forth, and error messages come up saying "no fuel", "power steering" and rotate between the two. While the car is doing this, it becomes hard to accelerate and the car surges randomly. It's happened frequently, and we have taken the car in to several different mechanics, all who cannot figure out what is causing the issue. We have replaced the main computer, and still are having the same issues. It is not safe to drive as I cannot see how fast I am going when the gauges start to go crazy, and the car will begin to think it's out of gas, even on a full tank. We have had so many issues with Chevrolet cars over the past few years that we no longer wish to purchase from them.

I bought my Cobalt in March of 2007. For the last year the radio will only play on the back speakers. The stero it self will play but some time nothing on sreen to show station or time. That not a magior as the problem the has happened now three time. When we go to stop at a light and push in on the cluck the car will die and the gauges on the dash will shoot over to the right and then to the left side fast. The car will restart. In the last month the front in will shimmy and shake when sppling the breaks. Dose it real bad when you slowing down when over 55 mile per hour. I have seen many complains on the front end. Wll it take a person to be killed for the chevy company to have the vehicles called in and looked at. I bought the car because of the price, mile per gallon of gas. And over all look.
