I've got 20000 km on my F150 FX4 now. Had it for about 5 months. I was driving on the highway at about 120km / 70 mph and for about one second all the warning lights on the instrument cluster came on - kinda like they would if the truck lost power or the key was turned just one notch before you start. All the gauges went to 0 (fuel, temp, tach, speedometer).
The rest of the truck was unaffected. There was no loss of power. My radio stayed on etc. It was just the electronics of the cluster.
Within one second it went back to normal.
Being a software guy things looks like there was some bug in the firmware or something and something rebooted / reset right away. Good that it did that. However, it would suck to be the only guy that has this problem because given that it has occurred one time in 5 months, they will never figure this out.
Anyone else have anything to report here? I hear that there have been flashes for the instrument cluster. None have been applied to my truck - it was made around the end of May 2009.
My first step might have to be to go and get the firmware updated to the newest levels.
My opinion, if this has only happened, one time, and only for a second or two, in the entire time you have had the truck, in essence a 'hiccup', I would not worry about it, for now, or until it comes up again. Especially since driveabiltiy is not an issue here.
Recently, I had my AT temp guage (only) dive to zero on multiple times, over the past 1.5 months. There was a TSB in the system for this specific issue and so when I was in for service last week they reflashed this component and all is well since.
Without a specific TSB and without it doing it for them while in the shop, or a code in the computer (unlikely) they most likely will not take any action for now.
