Recreational Vehicle Lpg Tank Valve/gauge problems of the 2009 Toyota Prius

Display for odometer, speedometer and gas gauge goes out intermittently. The �combination meter� (a. K. A. �instrument panel� or �cluster�, the thing you're looking at in front of you) is bad. There are several electrical components in the circuit board that control how it �powers up�, and they fail. Lacking the ability to power up, the display goes black. Joe myers quoted us $1156 for repair, and one week repair time. Service advisor said that repair part is fixed part so that problem will no longer occur. We must drive the vehicle till we replace it. No offer was made to provide a loaner car if 07 Prius went into shop for replacement cluster. It is really unsafe to drive without knowing speed that car is traveling. And we would not know gas level. Who wants to run out of fuel? very unsafe. Why isn't Toyota owning up to this deficiency? shouldn't it be a recall repair? we are the original owner and we have taken the vehicle into the dealership service shop for repairs since we purchased the vehicle.
