Contrary to huge investments in technology to reduce auto warranty costs and improve quality, auto warranty cost reduction has been quite elusive for many vehicle manufacturers.

One of the problems is that specific identification of the troublesome parts and less than desirable suppliers is a difficult and time consuming costly process. Automobile production, sales, and new car warranties create valuable data that could identify defective parts.  This data can not be fully used because it is too big to be cost effectively looked at by any data warehouse technology. The systems are made more complicated by constraints that make it difficult to cost effectively perform the analyses on data sets with speed and accuracy.
