Took my car in to be diagnosed and all they did was hook it up to the computer and did not test the faulty part or test drive it. They said they did not have the equipment to properly diagnose it and referred me to the dealer AND STILL CHARGED ME A DIAGNOSIS FEE OF $130. They should have told me they couldn't work on power steering before I wasted my money on nothing.
