I bought a used 2005 Scion XA in April 2010 with 118k miles. Based on my research & previous experience with Toyota; I thought I was getting a reliable and fuel economic commuter car. Unfortunately within 5 months and 7k miles later my check engine light came on. My mechanic told me heard a knock in the engine. 2 weeks later the car started to shake and the got very loud. I will never buy a scion again & lost faith in toyota's reliability.
