"What would be interesting is to see what each mfg has for expenses for warranty cost/vehicle sold. But I'll bet that is pretty highly guarded info. "
Actually, the info is available. I've looked at it several times. But what I found is at least a year old. And it's also a little difficult to figure out.
The link takes you to a site with a serious, long discussion. Probably because of the name of the site. But I think the info you want to see is contained in a couple of charts at the end.
To my uneducated eye, it appears that Dodge/Chrysler/Fiat is trying to get their per vehicle warranty costs more in line with GM/Ford.
