Recently purchased a used 2005 yukon. Have driven it 3 weeks. The traction assist feature frequently activates when accelerating from a stopped position, even on dry roads. Is this normal? It creates a loss of acceleration power, and this is concerning when turning to cross traffic, for instance. It is possible to turn this feature off, but the ower's maual does not recommend this. Any advice? I can't find any info on this on the internet.
Do you

Try this info, The Stability System Disabled message or Stability Not Ready message may be displayed on the DIC (Driver Information Center).

2. Unwanted Stabilitrak activation.

3. The vehicle lighting systems may dim noticeably.

4. The VSES motor may come on unexpectedly.

Recommendation/Instructions:
Check for excessive wear on any of the tires on the vehicle and then verify that all the tires are the same size, brand, and same model. It is also important to check and make sure the tire pressure is properly adjusted per the sticker on the door. The following examples listed below could cause any of the conditions listed above.

1. 2 tires on the vehicle are Goodyear P245/75R16 and the other 2 tires are Firestone P245/75R16

2. 2 Tires on the vehicle are brand new and the other two tires have excessive wear.

3. 2 Tires on the vehicle are Goodyear Wrangler SRA 265/70R17 and 2 tires are Goodyear Wrangler HP 265/70R17 (Same brand/different models)

4. Aftermarket Wheels and Tires (NON-OEM 20 inch wheels and tires)

5. Tire pressure is not properly adjusted.

Check this first and post back with what you find.

All tires are new, installed at time of sale, by the dealer. They appear to be the same size, all are the same make. The car notification center says "traction active" when this happens. It results in a loss of power, and the car almost appears to shift into neutral.
