Probably nothing to worry about, but my hour meter keeps resetting to 0 lately. First symptom of an upcoming problem?

Anyone have this happen and see further issues pop up?

That sounds a tad bit odd. Memory serves me right that information is stored only in the IPC? ? ?

sounds like the ground problem others were having when their hours kept resetting to zero.

Its a common problem. My 2005 did it last week for the first time.

IPC Engine Hour Meter Resets - keywords cluster DIC display hour meter intermittent start up #PIT4368A - (05/29/2007)2003-2007 Chevrolet Silverado Classic
2003-2007 GMC Sierra ClassicSome owners may comment of the ipc engine hour meter resetting. This concern may be very intermittent and normally occurs at key up and/or start up.

GM Engineering is aware of this concern and working on a correction. At this time there has been varying success repairing this concern with the following information:

<LI type=1>Check the battery/s with the Midtronic's battery tester and also perform a load test using a Vat40 or similar load tester to make sure the battery/s are in good condition. We have found in some cases a weak battery could cause this concern, this step is very important on vehicles with the 6.6L Diesel Engine where both batteries are used for cranking the engine. <LI type=1>Check the battery cables and make sure all connections are clean and tight. <LI type=1>Check the IPC powers and grounds (G200, G203, G100, G110 and the braided ground strap between the engine and cowl G104 and G107) connections and make sure they are clean and tight.
If the IPC has not been replaced, replace the IPC.

Mine did it just before the battery took a dump.
