Here in Vermont, us locals like to talk about the “5th season”, otherwise know as mud season. The Honda Pilot I have has AWD that doesn’t do too well in this 12″ mud. Its “traction control” cunningly stalls the engine power to ALL the wheels in the middle of a 30 yard stretch if mud.
The 4WD lock doesn’t do much better. Sure you can lock it, but you can’t go faster than 20 mph, otherwise it swicthes to AWD. I guess 20 mph works great on a wet NYC street, but it won’t give you the momentum to get across a Vermont road….
