Automobile repairs were evaluated in Atlanta; Philadelphia; Miami; Nashville; Houston; White Plains and Brooklyn. The project worked closely with the District Attorney's offices. A reputable repair facility was used in each of the cities as the secure facility. These secure facilities provided the inspection space and the master mechanics who assisted in inspecting the vehicles. Sixty-two cars were inspcted. Engine and suspnsion malfunctions were induced into these cars. The cars were then taken to randomly selected repair facilities. After the repairs, the cars were reinspected and the repairs documented. The results indicate that: (1) 39 percent of the cars had an unnecessary brake, engine, or suspension repair. That is, 39 percent of the cars had repairs made to an item which passed when the vehicles were inspected prior to being taken to the repair facilities. (Over repairs). (2) 20 percent of the cars did not have the induced malfunctions repaired by the repair facilities. That is, for 20 percent of the cars, the repair facilities did not correctly diagnose the problems and make the appropriate repairs. (Under repairs). (3) 51 percent of the cars had either an over repair or an under repair to the brake, engine or suspension system. That is, based on the sample of 62 cars, the chance was 50/50 that the motorist had repairs made which were not needed or did not have the needed repairs made.
