Everytime I start my vehicle, it resets the clock back to 1:00. The dealership said it was a sign of a bad cranking battery but it checked out OK. Any suggestions? Bad cables? Does it have a backup battery?
The trick is to check the battery under load. The starter motor is evidently drawing down your voltage below 10-11 volts. Somewhere in there is the threshold where the center stack display no longer wants to play and shuts down. First to reset is the clock.
This is actually a good thing. You can tell your battery although it seems to spin up the engine ok, has little reserve power available. You may have an internal short or collapsed plates in a cell. Whatever the case, a replacement is relatively cheap and the fix will save you some night on a dark, wet parking lot trying to prod your RX to life.
