Yeah, thats exactly what it is too! I can't tell you how many times over the years I have had "explosions" of gooey mess to deal with because of that stupid cupholder. Literally, the G forces from braking, turning, or braking/turning will launch anything larger that a can like a missile towards the shifter, dash, or the passenger footwell. I can't even count how many aborted liquid launces I have intervened after a close call and spill. Now its just habit to reach down when something is in there and I make an abrupt maneuver. Its to the point where I keep a large cup in the truck, and pour everything in it because it sort of "jams" into the cupholder. I'm wondering if it has something to do with "goo" in the shifter base and linkage, or if it really is mechanical. Maybe I'll get time this weekend to troubleshoot.

Maybe I'll just mount a camelbak behind the drivers seat. Too funny!
