One stop auto Beware of snap jugements Baltimore Maryland

I took my car to one stop 3 times for the check engine light and they kept telling me it was the same thing they replaced canister because they said that was what the code said on the machine I also had my brakes done and a tie rod replaced all total I spent over 600 dollars and the engine light was still on.  I took my car to another auto service center and was told that they just looked at the surface of the problem it was a hose under the engine that needed to be replaced all total 200 dollars.  I am sure that if you can't afford to take your car anywhere else because they offer in house financing just be beware and get a second opinion.
