Hey you guys! Ok, so i bought a 2008 sx4 sedan from the first owner about 2 weeks ago. Test drove it everything was fine. Soon as i took it home, it started shutting off while driving. Days later the engine light came on, the catalac converter is going bad. So i paid over $500 to get it fixed. The car still shuts off while driving, or when i come to a complete stop. Anyone else having or had such problems?
