I cannot say enough good things about Concourse. I was put in such a difficult situation when my check engine light came on the same day I moved to Grapevine. I took it to a nearby AutoZone to check the code, and was told it is typically a $300 fix (code was p000a). I took it in to a Firestone, as that's who I had gone to in the past, and they agreed that if that was the issue it would be about $300-$400 to fix it. They proceeded to run their own diagnostics and called to tell me the whole system (both cam/crank pos sensors, VVT solenoid, and camshaft adjuster solenoid) needed to be replaced and it would cost me over $1,500. I decided to get a second opinion, and after reading a few great reviews from jeep owners I decided to give Concourse a try. They gave me a call the same day to tell me that the check engine light was triggered by gunk and that with the proper maintenance it should be nothing to worry about. I have recommended them to everyone I know in the area, and will definitely be back. Their honesty and integrity mean so much!
