Had a strange thing happen on my truck a couple days ago...
We stopped for lunch at a rest stop in northern California after towing for a couple hours. Got back in the truck, started it up, and started adjusting/setting everything for another stretch of driving. One thing I always do before towing is reach over and press the Tow/Haul button on the center switch stack below the Uconnect screen, because Tow/Haul is always off by default after an engine shutdown.
This time the Tow/Haul button didn't light up or respond! Not only that, I quickly discovered NONE of the buttons on the center switch stack were responding... all were completely dead. I had no way to turn on Tow/Haul, adjust the exhaust brake, Park/Sense, etc. The seat heater and seat ventilation could alternatively be controlled through the Uconnect screen, so they weren't an issue.
I checked for trouble codes with my Edge Insight and didn't find any... not that I expected to.
I couldn't think of anything else to do but try but shutting off the engine and then restart it. Unfortunately that didn't fix it, so at that point I figured I had no choice but to just drive it without Tow/Haul and ultimately bring the truck to a dealer at our next overnight stop. So we left the rest stop.
As soon as I began accelerating onto the freeway, the center switch stack suddenly started working normally! It's been working perfectly ever since.
I'm baffled,
