No lights on dash and does it even when trac control is turned off. I have replaced both hubs and sensor wires. Car listed above is an ltz model.

If this only happens when turning left then more then likely it is an issue with a wheel speed sensor but we need to find out which one.

Also, if there are no codes then that means the module is doing what it thinks is the correct thing. So we need to rule out tire size issues as well.

Do you have the same age and size tires on all four wheels? Meaning did you replace one tire at different times then the others?

It sounds like the traction control is activating due to wheel slippage so this could be just due to one tire spinning at a different rate due to it being a different size.

So which sensors have you replaced? Both front? It is odd that it will do it with traction control off but I suspect this is triggered by the ABS which falls under a different area then traction control.

Do you have a scan tool that can monitor the wheel speed sensors and find out if one is reading differently then the others?

Below is the process for the rear sensors but let's see if we can get more info on this first. Thanks
