Help on Big Data And Data Mining

You are the CEO of Widget Vehicle Manufacturers. As part of the upcoming model year, the engineers designed the Widget 2021 TCB. During the last test run prior to production, the vehicle had a catastrophic failure with the newly designed engine. Fortunately, there were sensors throughout the vehicle. 

Would you use predictive or descriptive data mining at this point? What data would you use to research this? What time length of data would you use for this analysis?
