About that-
Is your 04' 4x4? I also have an 04, and mine's AWD with the option to go 4W Low. I have not seen this alert yet with mine, but you could try turning the "StabilTrac" off and see what it does. I don't know for sure, but I guess it would get pretty annoying if it warns very time it activates. I really don't have to know when it activates you know, so long as it does when it's needed.

StabiliTrak, Quadrasteer enhance driver control
GM’s StabiliTrak stability enhancement system – which will be standard on all Yukon and Yukon XL models by the end of January 2005 – assists the vehicle in maintaining the driver’s intended path by applying a brake force at any corner of the vehicle independent of the driver’s use of the brake pedal. StabiliTrak uses an accelerator pedal position sensor, a brake master cylinder pressure sensor and a steering wheel angle sensor as inputs to interpret the driver’s desired path and whether to accelerate or decelerate the vehicle. StabiliTrak also uses these sensors plus a lateral accelerometer and yaw rate sensor to determine the vehicle’s actual path. Yukon and Yukon XL models equipped with StabiliTrak also receive the G80 locking differential.
If the difference between the driver’s desired path and the vehicle’s actual path becomes great enough, StabiliTrak takes appropriate action to assist the driver with maintaining the desired path. If the vehicle begins to “snowplow,†or understeer, StabiliTrak applies the inside rear brake to help turn the vehicle. If the vehicle begins to fishtail, or oversteer, StabiliTrak applies the outside front brake to straighten the vehicle. StabiliTrak is integrated with the traction control and ABS systems.
On two-wheel-drive models, traction is controlled by transferring torque across the rear axle (rather than all differentials on 4WD models) to whichever rear wheel has the most traction. In four-wheel-drive models, drivers get full StabiliTrak benefits in 4AUTO. StabiliTrak can be partially turned off in 4AUTO and on two-wheel-drive models and still provide partial yaw stability and traction control, plus full ABS control. Only the engine management is deactivated, allowing drivers to freely spin the vehicle’s wheels when in deep snow, sand or gravel. In four-wheel-drive models, selecting 4LO completely shuts off StabiliTrak, creating a low-gear ratio with extra torque for better hill climbing, towing a boat up a launch or controlling vehicle speed for descents down steep declines without constant use of the brakes.
If you figure it out, send me what you know. I'm a new Tahoe owner, and new to all the bells & whistles it has. I just sold an 94 Chevy that I've been driving since June of 94, so this Tahoe's extras are way new to me. The only similarity is the way I have to squeeze it into my garage!
