Failed Vehicle Information

If a vehicle fails the on-board diagnostic inspection, it will need to be repaired and brought back for reinspection. Motorists are provided with information to help the repair technician diagnose the cause of the failure.

Motorists can review the "ranking" of repair facilities (called the Repair Effectiveness Index, or REI) on the Repair Facilities Locator page to help them decide where to take their vehicle for repairs. NOTE: Only repairs made by a recognized repair facility apply to cost waivers.
