    Hi all,
    My 2015 got a few light come on - traction, brakes & ABS. Stayed on for a few minutes then went off. Went to an Advance to check for codes, only code that came up was C1239. I had them clear the code, then went back home (lights stayed off on the 10 minute trip home).

    Anyone else get this code? What did it end up being? How did you fix?

    Any info greatly appreciated,
    Rob

    Experiencing multiple lights coming on like that can be concerning. C1239 usually indicates an issue with the steering angle sensor. It could be a wiring problem, sensor malfunction, or even a calibration issue. Getting a professional diagnosis might be wise to pinpoint the exact cause.

    The description for trouble code C1239 is "Foreign object is attached on tip of rear speed sensor LH".
