I have had the same problem. Start to roll away from a complete stop and at a very low speed around 10-15 km/h the traction active displays. I let off the gas and then accelerate again without a problem.
My mechanic says he puts on the computer to read out the codes and there is no indicator that anything is wrong. The sensors are all indicated to be working fine.
He said there is a unit under the passenger seat the controls the ABS and it costs around 500-600 dollars to get. An easy replacement except he says that it seems to be funcitoning correctly and that I should not throw my money away on something that according the the code reader says is working fine. He told me to come in again and have then read the codes when it happens again. We did. And still there is no sign that the traction system was engaged.
Like Jim here, the issue only occurs when pulling away from a stop. Any ideas anyone.
My short term solution is to always disengage the traction control using the dash button each time I get into the vehicle.
