The last attempt to solve the issue with the doors not unlocking was to change the lock relay. I have not had a issue since was changed two weeks

I Have a 01 Yukon Denali Vortec 6000 and i have electrical problems, when im on a stop sign the all the light start going down and then if i do a turn and its slow it looses power and just turns off, the engine dosent sputter, once the engine turns off i put in on park and start it, it will start right back up. I have Checked the Altenator and the Battery and they are all in good shape. I am wondering what can be the cause of this problem.

This just starting happening to my 2004 Yukon Denali. But prior to this I had a different message, "service stability" and the ABS and Traction Off lights went on. I believe these are connected but not sure. A chevy dealership service department told me I had to replace the hub and bearing on a front wheel (w/o looking at it, just told them what it was doing). Buyt they were not sure about the loss of power when accelerating and the "traction active" message. Your post is older so I assume you already have gotten it fixed, if so maybe you could tell me what you had done. thanks.

Here's the answer to my problem as explained to me by my mechanic. The multi-function switch that sits in the steering column controls the turn signals, hi/low beams, wiper/washer and cruise control. When you switch between high and low beam one circuit opens, the other circuit closes. The fault occurred on the low beam side and would not ground when I switched back to low beams from high. My mechanic was able to fix the ground problem by cutting the ground wire that ran from each headlamp back to the multi-function switch and grounded them directly to the frame. No doubt GM wouldn't approve of this fix but I wasn't about to pay $250+ for a new switch plus labor.

We have had this same issue on our 2004 since about 20,000 miles now we have 47,000, finally got GMC involved after many times of taking it into the dealership. Last week they replaced a wheel sensor, but now we are getting all sorts of messages coming up like the ABS light, Service Stability and the traction control off light comes on. Anybody else have these same issues?

Battery drain caused by new pump for autoride system staying on even when key removed. Checked relay - works fine. Now looking for diagnostic on controller. Bypassed system and pump works fine with shock leveling on demand.
Anybody got any suggestions other than Mr. Gut Wrench?
