Replying to: bigchuckwagon (Feb 07, 2008 6:36 pm) I am having the same problem with our 2007 yukon. Have you been able to find the problem?

Replying to: rsht (Jun 19, 2008 10:14 am) 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?

Replying to: tampapi (Jun 20, 2008 1:13 pm) When I visited my dealership for the BCM re-program, they told me that since I was there and there is a newer version of the software available they might just as well re-program the RCDLR all in one visit.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.

Replying to: rsht (Jun 24, 2008 7:49 am) 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? Replies to this message: rsht (Jun 24, 2008 10:19 am) tampapi (Jun 24, 2008 5:06 pm)

Replying to: rsht (Jun 24, 2008 7:49 am) 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?        Replies to this message: valvestud (Jul 25, 2007 7:25 pm) mikestgerm (Dec 08, 2007 2:59 pm) gaserup (Feb 22, 2008 9:06 pm)    #11 of 50 Re: What's the noise I hear when I open the door?

It will also run for a while after shutdown.

Replying to: tampapi (Jun 24, 2008 8:12 am) 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.

#53 of 69 2001 Yukon XL Noise by jaccicarpio Jun 24, 2008 (10:31 am)
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?

Replying to: rsht (Jun 24, 2008 10:19 am) 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.
#55 of 69 Silencing 2008 Denali NAV audible beep by chriswynn Jun 29, 2008 (10:06 am)
How do you turn off the audible beep when using the touch screen on the NAV/Radio in the 2008.
#56 of 69 07 Denali Nav Problem!!! HELP!!! by caseymarie Aug 13, 2008 (1:41 pm)
I have a 07 Yukon Denali. Sometimes (this happens at random)when I get in and start the car to go somewhere the nav/radio system will not come on. The screen will be black...just as if you had the car off. Only it's running. I then have to turn the car off and open the door (if I don't open the door it will not come back on once restarted) Once I shut the door back and start it again, the nav and radio will then come on.   Has anyone had any problems with this or have heard of this happening? I took it to a dealership and he basically told me that he didn't know how to fix it.   PLEASE HELP!!!! Replies to this message: mcj318 (Aug 13, 2008 6:51 pm)
