Vehicle Maintenance API

CarScan Maintenance API works on all vehicles sold in the US since 1996. It provides information on both OEM scheduled maintenance and non-OEM maintenance.

Non-OEM maintenance items are items that are consistently replaced at certain mileages and not included as part of OEM scheduled maintenance.

This API provides data on the following elements:

  • Name of the item
  • Mileage due
  • OEM or not
  • Difficulty of the repair
  • Estimated length of repair
  • Part needed for the repair
  • Cost of the repair

For specific details, please see our API Documentation for Vehicle Maintenance.

The Data field is a list of maintenance items. Each item contains one and only one maintenance item.

At a high level, each item contains a description of the item, the part needed for repair, and repair information regarding the maintenance item.


is_oem This field displays whether or not a maintenance item is OEM or not.

If it is true, it is an original manufacturer’s maintenance item and is listed within the their vehicle handbook.

If it is false, this is a item not in their handbook. An example of such an item is ‘replace wiper blades’.

At level 1, these are items most people can do on their own without significant training and casually following on an online tutorial.
