Refreshing to find an honest auto repair shop! I had a scary error code appear in my car while driving on Vasco but it disappeared after a short while. Did some troubleshooting with AI on my own first and it was saying I might need a new valve cover. I was bracing for a $500 repair. Brought it to JJ and they quickly figured out that the AI got it wrong and there were no safety issues with my car and the error was likely a sensor blip. Didn’t even charge me for the diagnostic. This experience has definitely earned them my business for next time I do need a repair. Thank you JJ team!
