So, because I evidently have too much time on my hands, using 2014 sales numbers the "corporate dependability" figure for Ford/Lincoln is 185.324. That's because there were slightly more than 25 Ford branded vehicles sold for each Lincoln branded vehicle sold. The figure for Ram/Chrysler/Dodge/Fiat/Jeep works out to 179.6207.
Adjusting for volume is pointless as it has no bearing on the actual quality of the vehicles since it is expressed in problems per 100 vehicles. So if I sell 100 vehicles and have 188 problems per 100 that means that in that sample of 100, I will have to fix 188 issues. No matter if that is 1 vehicle with 188 issues and 99 with 0 or any combination inbetween. IOW it's already normalized.
Quality is not related to volume in any way. Look at Toyota. Sells about the same total #'s as Ford with much better quality...
