Say goodbye to car repair rip offs! Know what's wrong with your vehicle before stepping foot in a repair shop.
CarMD goes beyond simply defining diagnostic trouble codes by using year, make, model, engine and transmission type, mileage and zip code to statistically assess and diagnose the most probable fix for each vehicle's problem. This database is helping consumers and professional technicians alike to solve tough check engine problems. When CarMD presents a most likely fix for a vehicle, its database is sifting through more than a half-million real-life fixes made by skilled ASE-Certified Technicians who work on cars just like yours every day.
We are so confident that the CarMD® Vehicle Health System™ will correctly diagnose your vehicle that we offer the CarMD® Get it Right the First Time Guarantee. If CarMD ever gives you the wrong diagnosis, we will pay for your repairs up to $500. See our policy page for more information. In less than 5 minutes, go from plugging CarMD into your vehicle to receiving your report. CarMD is easy to use and comes with simple to follow instructions.
