"The CD/Nav disk motor constantly runs" is not right. Mine shuts totally off as soon as I open my driver side door (with the ignition key already turned off of course). Perhaps ask your service department to double check the CD's wiring? I have an 07 Denali, I must say that I have been very lucky, it can sit in my garage for 3 weeks (the longest I have ever tried - due to an over sea business trip) and still starts just fine when I got back.
BTW, has your Yukon been through the recall service called "BCM Reprogramming for Battery Drain"? When I had mine done just more than a year ago, my service department also reprogrammed the the RCDLR and RKE Modules...

I am having the same problem with our 2007 yukon. Have you been able to find the problem?

I just called the dealer and asked if they did the BCM - they said yes, it was done during my last oil change earlier this year. However, they did not repro the RCDLR. Since you mentioned it, I did some research and see that this was a big issue on the Vette and Tahoe, but I didn't see a bulletin regarding the Yukon.
I called them back and they said they were not instructed to repro the RCDLR on the Yukons. They didn't understand what it would have to do with the battery run-down issue. But from what I'm reading, it's more of a software issue. Do you think I should make them do this?
I was under the impression we have run-down protection anyway, so if something such as the disk motor is running, why isn't the run-down protection kicking in?

When I visited my dealership for the BCM re-program, they told me that since I was there and there is a newer version of the software available they might just as well re-program the RCDLR all in one visit. I am not all that sure what each re-programming does and to what extend the sensitivity level in the new software is (if at all different/adjusted from the previous version) as far as detecting the electrical drain and etc... All I can tell you, since the re-programming, I have not experienced any issue with the battery running out of juice, even I have parked my 07 Denali for 3 consecutive weeks.

What does your battery meter in the dash read normally? Before they did the re-program, were you experiencing flucuations in your meter? From what I understand the normal reading should be around 15 volts. Mine has been resting at around 11/12 but will flucuate down toward 9 volts. When I'm stopped, it will go lower, when I'm moving - especially on the interstate, it will go back up to 15. So there is obviously an issue with the output from the alt. Did you experience any of this?

I just found another message on the board regarding the CD reading noise I've been hearing - I think this pretty much explains that issue, so I don't think that has anything to do with my battery running down.
#10 of 50 What's the noise I hear when I open the door? by 10mikeymike Jul 25, 2007 (3:46 pm) Save | Reply
I just took delivery of a new 07 Yukon Denali. It has the navigation system and every time I open the door, I hear a faint sound like an autofocus camera focusing. The only thing I can think it is would be the navigation system rreading the disc, but the vehicle isn't running. Has anyone else noticed this?

Anytime you open a door on the vehicle when it's been sitting for some time, the NAV unit spins up and gets ready to do it's thing. It will also run for a while after shutdown.

Before the re-program, my battery/voltage meter has been pretty steady at 15 almost every time when I looked at it. Since the re-program, there has been more movement between 15volts and ~12volts if I have been driving for a while... Nothing lower than 12 has ever been observed in my case.

2001 Yukon XL Noise

Recently my yukon will make a noise that sounds like a chirping or a plastic bag caught in a fan. It only makes it when the A/C is on and it is very hot outside. It only makes the noise while driving/accelerating. If I let off the gas the noise stops. Also, once the car has been drving a bit it doesn't make it. Any thoughts?

From what I understand, there should be no flucuation of that meter. If anything is operating property, it should read a steady 15volts. But I guess if you are running a DVD player, GPS and all the toys, it might make a difference.

How do you turn off the audible beep when using the touch screen on the NAV/Radio in the 2008.
