The problem, IMHO, is that they market and sell some vehicles by promoting a certain image. If you buy the vehicle and try to do what you see in the marketing, you get told it is abuse.
With the WRX, it is sold as 0-60 in 5.4 secs and we see ads of it doing all sorts of high performance stuff. How many 5.4 sec runs before the tranny breaks?
I bet it is the same with SUVs. If you take them for an off-road pummeling, like they do in the ads, you'll break them and get no warranty help.
I can't think of any other products that are sold based on showing usage that is really abuse. Imagine if they advertised a ladder that claimed to hold 250lbs then told you it was abuse if you actually put 250lbs on it.
