Maybe it's just the Uconnect infotainment system. The PDF I linked above is the in-depth Jeep hack run-down, and a huge huge huge part of it is playing around with the many many many many DBus services.
Is QNX just a kernel, no userland for it? I would have assumed it might include higher level offerings, including I would guess, to be helpful, some cross-system messaging options. Until now it's been impossible to guess. But yeah, it's quite likely this DBus stuff is just Dodge's repurposing of (not fantastic but reasonably ok and well known) messaging tech, DBus, layered atop.
