Basically, it's because the US Intel services are staffed by morons. I should know, I've worked with them, and sometimes still do.
ISIS and other bad actors make extensive use of Toyota Land Cruisers, many of which are of recent production.
So the idiots in the US Intel services try to blame the Land Cruiser, much like gun control idiots/advocates blame guns for violence. US Intel services have even gone so far as to accuse Toyota of supporting terrorism.
The fact that anyone with a brain in their head will choose a TLC for transportation in the Third World, and that the LC is ubiquitous there doesn't even register in the Intel communities' Northeastern US Elite-dominated pea brains. And that ISIS and others can easily just buy the rigs of choice off the shelf also startles them into panic mode.
Sorry for the diatribe, but I've supported our so-called "Intel Community" since 1982, and have developed a healthy skepticism of their utility.
