I have an 08 LR3 that I bought 1 year ago. As far as I know, it still has the original battery. I just returned from a 4500 mile trip to New England, where I began sporadically noticing the info section of the gauge cluster being reset when I started my truck. At first, it was usually in the morning after having sat for the night, but now it's every time I start the truck. The tripometer resets to 0.0, and the rest of the info is set back to only showing the clock and the temp (which I usually keep set to show my distance to empty.) Any suggestions, observations? There seems to be no sluggishness upon starting the truck, but this little gauge cluster thing is kinda starting to drive me crazy.
