Check engine light on? Check Hum first.

The best time to find car trouble is before car trouble finds you. Hum lets you check your car’s health from your phone and detect problems before you go, and it automatically sends you alerts for hundreds of issues. It even gives you the Diagnostic Trouble Code (DTC) so you can be on the same page as your mechanic.


Now you can

  • Check your car’s most critical systems

    Get detailed data on your car's health so you can hit the road without hesitation. Hum automatically monitors the status of your car's battery, coolant, alternator, mechanics, electronics, powertrain, wiring, and emissions.

  • Be informed when solving car problems

    If any issues are found, you'll get an alert with the actual DTC and a thorough description of the problem. You'll know what's going on and how severely it may impact your car, so you can make informed decisions moving forward.

  • Stay ahead of car maintenance

    Use Maintenance Reminders to help keep your car running right. Get email and/or text alerts when it's time to take your car into the shop for oil changes, tire rotations, and more.

Hum detected low voltage in my battery. I was able to get it checked and replaced while it was under warranty. Hum saved me out of pocket expenses and kept me from possibly being stranded.
