I have an 05 Malibu Maxx and while driving it the other day the ABS, traction control, and Brake lights came on. After doing some looking online several said it could be a speed sensor or wiring to sensor in one of the wheel hubs. Took it to have codes run and was told it was the back left, checked the wires then replaced the hub but still have same issue. Any thoughts? Would be much appreciated.
