Recreational Vehicle Lpg Tank Valve/gauge problems of the 2017 Hyundai Tucson

Vehicle frequently, intermittently, stalls during take off from a stop. When accelerating from a stop sign or traffic light vehicle will simply roll as if it is freely rolling in neutral but is not receiving any power or acceleration from the engine for approximately 3 to 5 seconds before engine/drivetrain engauges and vehicle accelerates. This creates an extreme safety hazard when you have the vehicle in an intersection and accelerate to make a left turn in a gap in traffic and end stuck in the intersection or in front of an oncoming vehicle because the vehicle is only rolling and not accelerating. This issue has been reported to Hyundai USA corporate who has chosen not offer any remedy and has it stated to me this is a "characteristic of my vehicle. ". Hyundai USA has continually referred me back to the dealership, who does not have a fix for this issue. Hyundai USA has even place the blame for this issue on the dealership. However the issue here is that Hyundai USA engineers have not admitted to having this problem or created a fix to this problem to roll out to the dealership to allow them to remedy this problem. This identical issue has been reported and issued as a recall in prior models of this vehicle, yet Hyundai refuses to do anything on this model.
