After some time off for the Holiday Season-we are back with a new episode! We delve into the recent news of Hertz's huge sell-off of used Teslas and the risk to the consumer regarding actual battery performance. Do we know about the battery management system's health and can the average local shop test beyond what is captured on the big screen during a pre-purchase inspection for a deeper dive into condition? On this edition of WrenchNation, we are honored to have first-time author Shahe Koulloukian, a renaissance man of many talents and skills. One of which is his longtime passion not just for cars- but the people who drive them. An automotive TV spokesman, sought-after guest on television shows, speaker, educator, and founder of Mazvo Car Care Center in Phoenix, Koulloukian released his first book, “Car Confidential: Insider Secrets About Automobile Ownership, Car Maintenance and Road Safety” in November 2023.
