Recreational Vehicle Lpg Tank Valve/gauge problems of the 2010 Chevrolet Malibu

Dash lights: esc off, service esc light, brake system (!), abs system, power steering, lights flash and all gauges fluctuate. I have replaced the main control module, as well as power steering module at dealership, and the problem still continues!!!! have read about other same models doing this same problem. It will come on, and then next time I start my vehicle, it stops. Then comes back on. Sometimes stays on for weeks. Or is gone for weeks. This has happened even with professional repairs. This happens when stationary and idling and while driving.

The instrument cluster that controls the gear shift that shows if I am in park, reverse, drive, manual don't work with this issue as well as the control panel behind the steering wheel that shows my miles per hour, fuel level, temperature gauge, mileage and more. This is a severe safety risk and I have had my part for this ordered twice but there is so many of this year, make and model car that is needing them that they are back logged out several months. I live in valdosta GA and have to drive around town for the law firm that I work for and this car is so unsafe that I can't drive it bc I have ran out of gas several times and was stranded. Can't tell how fast I'm going so I have been pulled over several times do to that as well.

2010 Malibu experiences fluctuations in power/ rpms when trying to accelerate. I have taken the vehicle to get looked at severals times, but mechanic could not get the car to replicate issue. Not sure if its related to the fuel system, transmission, or motor. Either way, no one can diagnose this problem. When issue occurs, the vehicle acts sluggish (does not want to go) and bounces between 2 & 3 on my rpm gauge. It's as if I would push the gas then let off the pedal (repeatedly). At first this only happened when going up a hill, but has become more frequent, and is now happening regardless of grade. It is a definate safety issue, as this has occurred when crossing an intersection and merging onto a highway. It does however seem to be resolved if I press the gas all the way down (rpms go up to 4-5 on gauge, then the car finally goes) I have seen many complaints about this online, but no resolution. The number of miles the car has does not seem to be a factor, as this has happened to others with this car being brand new (based on other complaints). This has been happening intermittently for months. This is my first chevy- bought last year. Seems to have a ton of electrical issues. Bought the car unknowingly with an open recall, tire sensor light comes on intermittently for no reason, car suddenly stalled on the highway and would not start a week after purchased, stereo loses power, power steering is intermittent, the passenger door sometimes fails to open and/or close, the driver side door loses power intermittently, the exhaust is rusting, ect. I did buy a warranty with this car, but being that nothing can be diagnosed, its a waste of money! I still owe over $8000 on this car, and paid blue book value! -Chevrolet totally misleads their customers. Never again OH, and I did recieve a recall letter about my power steering, but the dealership says there is no recall.
