How do I help with the Car Reliability Survey?

  • You'll receive a periodic email with a link that automatically logs you in and takes you to the survey.
  • No repairs? Just report an approximate odometer reading each quarter so we know to include your car in the stats.
  • Car required a repair? Report it using a one-page survey form.
  • Optional: posting repairs from before you joined, fuel economy, and the reasons you bought the car.
  • Time required: a minute or so per quarter plus a couple minutes per repair.
