Anyone know a good Prius mechanic in Dayton Ohio?

Hi everyone. New Prius owner and have the cold weather knock. Does anyone know of any reliable mechanics near Dayton Ohio who can help with this? preferably not a Toyota dealer.

I have a 2012 Prius v with 148k miles. Drives well and the sound and heavy vibration goes away when the cars warm. It is throwing a CEL with the codes reporting misfires in 3/4. 2 pending and 1 confirmed. Dealer I bought it from told me to take it to a shop and that he’d never seen any issues with the car and that it’s in excellent condition. He thinks it could be old gas because the car sat for 4-6 months

 

I’m fairly certain it’s a head gasket issue. Pulled the service records and the dealership said car overheated and blown head gasket not repaired :/
