    These warning lights/messages all came on at same time:
    Slip indicator, 4Lo 4Hi, blind spot indicator, ABS, Brake controller error, and master warning.
    Computer diagnosis indicated bad right rear wheel sensor. Mechanic replaced sensor but nothing changed. Any ideas?

    Correction- it was the LEFT rear wheel sensor that computer said was bad and mechanic replaced.

    Sometimes low battery voltage or a bad ground can cause all manner of issues in newer vehicles.
