Check Hybrid System Stop The Vehicle In a Safe Place 2013 Prius

Hello everyone! I have a question about my 2013 Prius Persona. It has 66k miles and has been serviced religiously every 5k. After replacing the cabin filter today I went to take my Prius for a drive and all of the sudden I received the "Check Hybrid System Stop The Vehicle In a Safe Place" come up along with my yellow warning triangle, loss of power steering and check engine light. I made sure all of the plugs were still connecting underneath the hood and everything seemed to be in order. When I would pump the gas the car would move and then stop and I could never get it in ready mode. Now the engine is unresponsive. All cabin lights and accessories seem to be working fine. I just had it towed to my Toyota dealership. Any ideas as to what occurred? I'm going to the dealership tomorrow to find out so I will keep you posted. Thanks for any input!

 

Thanks for your help! I just looked into the inverter and it seems they extended the warranty on that part due to trouble. Fortunately, I can walk to work and my wife has a honda civic we can drive. I wouldn't mind having a loaner though. We'll see what happens.
