Replying to: teto4sure (Feb 03, 2008 10:27 pm) Check your coolant level in both the radiator and recovery tank. Replies to this message: teto4sure (Feb 05, 2008 10:34 am)

Replying to: obyone (Feb 03, 2008 11:46 pm) Thanks!!!!!! I added more Dex Cool coolant and it works. I can't believe when I got my oil changed last time they didn't check it. Thanks.
#3191 of 3260 New '06 Denali owner researching the "clunk" by jgordo Feb 27, 2008 (2:00 pm)
Hey Guys,   I hope this question is not redundant, but I brought home a '06 Denali with 36000 miles (exactly!) and so far have been thrilled with it. The V8 sounds awesome, the comfort, ride, nav, AC, towing, AWD, DVD and storage have been fantastic. However, I had to get 2 rear tires and the truck aligned. After aligning, I drove away and heard a "clunk" from the front drivers side. It persisted until I turned around and took it back to the alignment shop and told them to check it out. They did, and couldn't find anything. When they took it down off the lift, it ran great!! No sounds, just smooth ride. Fast forward to yesterday, then the Mrs. took it to work, and at lunch, she heard the clunk. She did not hear it in the afternoon. Am I going crazy here? Luckily, I did buy the extended warranty. If this issue has been discussed in another post, let me know and I'll head that way.
#3192 of 3260 GMX-320 LOCKPICK by mitchdenali08 Feb 28, 2008 (6:26 pm)
does anyone have experience with unlocking the nav screen in Yukon Denali's. I have come across the lockpick from costaltech but I am concerned how well it works. the video demo on their web site appears that it is a good product. Replies to this message: brewboy (Feb 28, 2008 8:49 pm)

Replying to: mitchdenali08 (Feb 28, 2008 6:26 pm) I bought one of the Coastaltech Lockpicks and it didn't work as described so I tried to send it back. They dont answer their email or phones so it was a nightmare. Eventually I got my money back months later but lost the Fed Ex return charges. A friend has one installed and it works fine. Be careful of imitations that dont work.

Replying to: jbuhac (Mar 17, 2003 8:52 pm) I have a 03 yukon xl right now that is doing this. We bought it used. Has may be 37000 miles right now. I went to get in the car and it said unknown driver. When trying to start it didn't start right off the bat. Then it started on the second try. Said unknown driver, and then the gauges would not work. I then turned on the headlamps and the car horn honked and the gauges jumped and went to there normal readings. I have a idiot light on that shows a sub with a lock through it now. ANy ideas or suggestions. Thanks for your time. Replies to this message: rsht (Mar 10, 2008 7:28 am) denalidude (Mar 10, 2008 8:28 pm)

Replying to: denalidude (Mar 09, 2008 5:14 pm) A friend of mine had the similar issue. What we later discovered had to do with one of his ignition keys which he has been using daily for years... To make a very long trial by elimination story short, we disconnected the terminal off his battery for about 30+ minutes then used his second OEM key (and as far as I know he has been using it ever since), all has been working fine. Not so sure if that was luck or the right approach though. Good Luck! Replies to this message: denalidude (Mar 10, 2008 8:28 pm)

I have a '05 Yukon XL Denali and noticed that the bulb/led that illuminates the volume button on my steering wheel light is out. Does anyone know how I should replace it? Thanks.
