DO NOT TAKE YOUR CAR HERE!!!! Although Mr. Kim claims to have 28+ years in the automotive industry, he is a liar and a thief. On top of the standard diagnostic charge, he charged me to confirm the diagnosis and then of course to "fix" the issue. I had a vacuum leak and he took some tape and wrapped it around the hoses. He cleared the OBD codes, and sent my mom on her way back to Chicago. Within an hour of driving, she was experiencing the same issues. We had a mechanic in Chicago look at it, and he said that the hoses should have been replaced, and no reputable mechanic would have just tried to tape over the cracks in the hose. Do not trust this shop. They lie and then hold your car hostage unless you pay whatever they feel like charging.
