Brake Fluid Leak Problems of Toyota RAV4

I am filing a complaint about spongy brakes behavior in a 2012 Toyota Rav4. The problem I was experiencing were the brake pedal traveling to the floor and reduced stopping power during application. The spongy behavior of the brake pedal was also present with engine off. I report this event to two separate Toyota dealerships which technicians claimed this is a normal function and this is a soft pedal design (according to the first dealership). The second dealership showed me another similar vehicle (2011 Toyota Rav4) and it almost did the same thing (engine off - pedal was still spongy but was less than my vehicle). Since being a ase master technician before becoming an mechanical engineer, I bleed the brakes which only helped a little and there were no fluid leaks. Finally, I researched that the abs pump might need to be activated using a scanner to cycle the actuators that might hold air trapped inside. I took the car to my previous place on employment where I consulted this issue with the shop manager in which he agreed that this is a possibility. The shop manager performed the abs pump cycling process with the scanner and the brake pedal became hard and firm like it suppose to be (procedure time: 5 minutes!). I am very disappointed with Toyota trained technicians and any good technician knows there is no such thing as soft pedal design especially with a vacuum brake booster with engine off (hydraulic fluid is only slightly compressible!). Only vehicles with hydraulic brake booster can experience a brake pedal feeling spongy since the booster will continue to function after engine had been turned off (approx:10 ¿ 20 brake pedal applications ¿ diesel & very few gas vehicles). It seems to me Toyota is skipping a step in there manufacturing process.

I have ha the car back to the dealer for this brake problem and they said this is normal ,what the problem is the brake pedal is soft and when braking you foot can hit the gas pedal this also the pedal will go down when you are holding at a stop,also its not leaking brake fluid as the car was service at the dealer.
