I have not had an incidence but very concerned about the malfunction that is going on with my vehicle at this time. . I noticed a scrubbing/grumbling noise when I would turn the wheel either way left or right. After vehicle being put on machine for testing it was discovered that the upper strut mounts and bearing were worn and noisy on front struts. . . . . . Also my abs and traction control light both came on at the same time and would not go off, the information system in vehicle recommended brakes be service. . . . . The results from car being tested showed both front hubs have slack and both front wheel speed sensor harness are coming apart inside wire installation. The codes for abs/traction control is. . . C0040 00. C0040.
