I have set my clock back 3 times!

1st time while warming up in the driveway, I noticed it needed to be set back an hour.
2nd on my way home, "WHAT!" how could it be that late? Looked at my watch and reset the clock.
3rd time go to work in the morning, time is correct. Come home at night and need to reset the clock back an hour again.

menu - settings - clock: dial back 1 hour, set, back, back, etc.

What could be going on that it can display the correct time, but somehow remembers the old time?

 

I think there’s a daylight savings option too somewhere if I remember.

 

Yes the time zone and daylight savings time are set on the PCM. I think it's press Main then Set to bring up the menu.
The click is resetting because it uses GPS to set the time.

 

mine started doing this the past weekend too after i updated it for DST. The odd thing is it wasn't switching to a time that was off by an hour, it was changing both the hours and minutes to something way off.. after it did it a few times it seems to have stopped. i assumed it was getting some wacky value from the gps somehow.

 

Basically every time I shut the car off for more than a few minutes, the clock would advance exactly 5 hours!

Monday, I had to rescue my son on I-95 south of Fredericksburg, VA. The alternator in his truck failed driving back to FL. So after replacing the alternator in the parking lot of the Best Western we needed to jump start his truck. My jump starter would not do anything on his dual battery diesel truck. At first jumping with the Cayenne wouldn't either, so we let it charge 5 minutes and then with the jump his truck started up.

I just went out and checked, my clock is still on the right time!

 

it was 5 hours fast this morning...

 

I am having same issue and my auto lights dont switch on when i unlock the car
