I would really question them on the battery. Our 2007 Denali has gone dead at least four times. It will be starting/running fine, you stop to run in the store and try to start back up and it is dead. Leave it sitting and come back several hours later and it starts up just fine. OnStar tells us the battery is dead but if you disconnect it and test it, it tests fine. The last time it happened, I had it towed in to a local GMC dealer. By the time they got around to checking it, it started fine again. You can guess that we got the same answer you got, "could not reproduce the problem, no problems found". In my opinion, there is a major problem with the on board computer but I can't get the GM dealer to admit that or replace it. Maybe we should just sue!

In an interesting turn we now have charged the battery and replaced the negative cable. I have been checking the battery with a multi meter on a daily basis for over a week morning and night and the battery is reading 12 + volts each time. I am amazed but it would at least appear that this has fixed the problem. They said that the alternator charges the battery through the negative cable and a bad cable would prevent the battery from charging . Mine never would come back with out a charge or jump start, once it was dead it stayed dead.

Man ! I had a similiar problem a long time ago. The main power cable from the positive side in the fuse box with huge fuse. You will see connection tie together by nuts or some sort. sometime you have connection or you dont. I got this vehicle straight from the dealer brand stanking new. This may not pertain to your vehicle but i share your illness. good luck !!!

You have to insist on 800 CCA if they give you anything lower. Mine had a 700 CCA and I was having the same problem until I changed it for the bigger CCA battery.

2000 GMC Yukon Denali Fuel Gauge Issue
by maxmad

My fuel gauge on my 2000 Yukon Denali, has started to vibrate in position after the vehicle has been running about 10 or 15 minutes. The vibration is so fast that the needle looks twice as wide as it is. When driving the dampening of the needle is not always there anymore. If you turn the vehicle off then back to the on position the gauge swings clockwise past the full mark to a hard stop point for about 5 or 10 seconds. It does seem to be reading about right. When you first start the vehicle cold, everthing seems fine for awhile. Any help would be appreciated. Thanks.

I have a 04 Denali XL. There's no popping in the steering column but I had to have the steering gear replaced because of vibration and a grinding sometimes squealing noise when making sharp left turns at a slow speed. The problem has re surfaced and only does this when the engine gets up to normal operating temp, I'm from the southeast so the problem is more noticeable during the hot summer months. Someone suggested that I need a front end alignment so I'm taking it to the shop for service and a all around lube job to see if that helps. Will let you know the results. Thanks for the info on the A/C because mine blows hot air from the driver's vents but the front passenger and rear continues to blow cool/cold air. I'll check the belt tensioner and will probably change the serpentine belt. Will let you know.

02 GMC Yukon XL Power Surge/114K Miles

I'm having problems with a power surge that started about 15 months ago. Had to replace year old battery 12 months ago. All lights (interior and exterior) "strobe" during operation. Took to GM dealer and was told that factory recommends re-routing wiring. Alternator was checked but is putting out proper amps. But meter does show surge. Can someone help me b/c I don't want to play the "let's try this to see if it works" game that the dealer wants to play.

2007 Yukon Denali XL

I am having problems with the battery running down also, with only the radio playing. Now the battery seems to be bad or not getting charged. I had not heard of the recalls that were mention pertaining to ID#07007 and etc. Besides the battery, I recently had the air conditioner blowing cold air on the passenger side and hot air on the driver's side of this vehicle. I tried the controls but did not fix. When I turn the vehicle off then back on, the air started flowing correctly. I hope the repairs that were mentioned will
correct these problems. I will look at getting a new battery or a second battery. Any other suggestion will be appreciated.

Our dealer replaced our negative battery cable (which I thought was crazy) and it seems to have fixed our battery problem. They said GM was not sure what was wrong with these cables but they have replaced several on the Denali and it is fixing some electrical issues. Who knows, but so far three weeks have gone by with out any problems.
