Did you ever get a resolution to this? My 2008 Yukon is having the exact same problem and the dealership can't figure out what's wrong/how to fix it. It's been in twice now with the issue - once in the fall when I was stranded and the thing wouldn't start, and now just before Memorial Day and they pulled codes on it again today. I tried to email the socialmediagm.com to see if they could help, but they apparently only respond to people who put them on blast on forums.
My PLAN was to drive this Yukon to 100,000 miles then trade in for another one, but I'm only at about 60,000 miles and am wondering if it's time to ditch. I have a 4-yr-old and 2-yr-old and hate not having a reliable vehicle!

I found this POST to be the most spot on for my scenario.
Frome what I've read, replacing the negative battery cable resolves this close to 90% of the time. I've got 76xxx miles so warranty wasn't an option the dealer said. I've only had it back for one day but so far so good. The cost was $96 for the part and $214 for the labor.
No help from GM Customer Care although I tried. How does GM get away with this? It's not a matter of if this will happen to the models listed in the bulletin, it's when! Should have been a recall as should have the door lock actuators!
When I got home and looked under the hood I almost cried at the money I'd just thrown away. Too simple of a job for that kind of money.

My dealership service team came back saying they got a bulletin from GM and thought it was the alternator, but they did not seem at all confident in that diagnosis. My vehicle's symptoms are very similar to yours as well as busymomma's. Today, while accelerating my stabilitrak suddenly turned off and the airbag light started flashing. Then when I restarted it, everything reset itself again (clock, AC controls), and my dash told me to service the 4WD.
I think I'm going to get a second opinion from a reputable, independent garage in town and possibly just have them do the work to save $$$. I'm really worried this is a bigger "motherboard" problem and the $700 quote for the alternator is just the beginning of bigger expenses to come. Depending on costs, I may have them go ahead and replace the battery cables too and see if the combination of fixes takes care of the problem. :o(
If anyone else has any insights on these bizarre symptoms...I hope they share.

I needlessly replaced the alternator and battery. A new negative battery cable seems to have fixed it. I am still not happy with the performance of the voltage meter...it goes from a slight charge condition upon starting to a near 12V condition when traveling...but the company I bought my new alternator from said this is normal since the BCM only calls for the alternator to charge when the battery is low in order to conserve fuel. Anyway, I would go for the battery cable...and it is easy to replace. All I want for Christmas is a car with no computer!

Replacing the negative cable did the trick for me. GM Customer Care opened a case for my issue the day after I picked up my truck from being repaired. Since I'd already paid they offered me a certificate towards future service or routine maintenance. They will help on these types of known issues if you post here and also email them. Looking back I wish I would have gotten a quote from a reputable chain and had my local dealer match it as they were quite pricey to deal with.
#141 of 169 2004 GMC Yukon Denali Intermittent Starting Problems (will not turnover)
Jun 16, 2013 (6:07 am)
I have a 2004 GMC Yukon Denali XL, and I love it or maybe I should say loved it until I started having starter issues about 2 years ago. My SUV will not start in the heat of the day. It is worst in the summer then winter. It will start for me in the mornings and late evenings or at night as if nothing was ever wrong with it. But, in the heat of the day, it is dead as a door nail. In this case, If I pop the hood and open the windows for a while, sometimes 5 minutes and other times hours (on cooler days), it will start for me (but then I have no AC and the ride is rough). Sometimes a jump will start it, but I think only because on the days where it will not start Iíve tried it so much I have drained the battery (I really donít know). I gather at these times it has cooled enough and weather is cooler, I get a jump and it starts.
I donít know if it is the computer or what. Iíve had the alternator changed, the starter relay and the starter ignition, but nothing seems to fix the problem. I didnít have the starter changed as it checked out alright.
Also, on particularly hot days the temperature gauge on the rear view mirror goes hay wire. Then when the car cools off, it will reset and start working again.
Please help! I am a single mom of 3 kids and not in a position to buy another auto at the moment. If someone has experienced similar issues, please let me know what you did if you were able to resolve it.

I have a 2006 GMC Yukon Denali. The gauges on the instrument panel are all not working except the gas gauge and the speedometer. Is this a common problem ? Is there a recall on the instrument panel ?

I have not had any additional occurrences since they changed the second (negative) cable. They were expensive and I was disappointed that GM did not at least cover the cost of the cable since this seems to be an extensive problem and there is an SB or notice or something about the problem. One issue I do have is with the clock. I have to manually reset the time to the daylight time during DST periods. Once we go back on standard time, it is fine. Go figure. Dealer has no solution. Apparently GM doesn't give Mr. Goodwrench upgrade training for Mr. High Tech!
