Well managed companies track part defects and implement immediate corrective action so they don't build defects into their products. They trace the cause of the failure and raise hell with the maker of the part.
When defective parts get into the field it is very expensive to make the repair. The failures can also put the user in danger.
When you manufacture products such as radar for boats and aircraft there is a real need for recall and repair. However, the boater is not in as much danger as an aircraft so the manufacturer can be more careless with his quality management
Sometimes a company has defects in their products and they see the repeated failures of a part almost immediately. But they do not react and as the parts fail, they charge the customer for repairs. When this happens the quality management system starts to fail systemically. So if you hear about problems with products in the field that are not recalled and corrected immediately then you have to conclude that there are systemic quality management problems.
