Recreational Vehicle Lpg Tank Valve/gauge problems of the 2019 Toyota RAV4

The gas tank will not fill to the full capacity and gauge is inaccurate. The fuel tank size is 14 gallons but I discovered after owning the car for a month that the tank will not fill completely in fact it only fills to 10 gallons meaning the stated vehicle range is false advertising. I have contacted Toyota and opened a case but receive no update or feedback.

Mte, gallons to fill up, don't equal the miles to go after a fill up. Have had car a year, have only filled up once more than 10 or so gals, doesn't matter how many miles to empty show on gauges. Don't get anywher near the miles driven that was told to me. I fill up, usually takes about 9-10 GLS. Will have less than 500 miles to drive on that tank of gas. Driving local and on highway.

I bought a brand new 2019 Rav4 limited with 150 miles on the odometer, now has about 460 miles. A few days into the purchase, I noticed yellow tick marked glitches showing up on my drivers center main console. This main console displays my mph, speed limit, lta, and more. I thought nothing of it as it went away for a few minutes when I turned on/off my car, but it would show up again. After these yellow tick marks started showing, my whole main center screen will go black with only the rear seat belt red light, park, and bsm lights flashing. In addition, my analog rpm, gas gauge, and temp gauge were all down. I was driving blind for a while, until I had to pull over on the highway/street to restart my car so that I can see my main dash (rpm,mpg,temp,gas,etc) again. Some of the pictures that are attached with black screen are examples of myself turning on/off my car while I was stuck in traffic so I could restart/see all of my main dash console gauges, rpm,mpg, etc. When my screen goes dark, I have to look at the other cars to match their speed because I was basically driving blind. This is a serious safety concern to myself and my family! I have a video of this scary occurrence, but the video file is too big to attach. I took the car in the day of this started to happen and it continue to sit in the dealership.

The car's fuel tank does not fill up. Each time I fill up, it allows approx 10-11 gallons of a 14 gall tank. Unclear if the fuel gauge is working or if the alert for needing gas is accurate. Not performing as advertised.
