ISSUE CONTINUES TO BE DIAGNOSED AS A FAILED BRAKE LIGHT SWITCH, AND SWITCH IS REPLACED. NEW SWITCH WORKS FOR 3-6 WEEKS BEFORE FAILING AGAIN, RENDERING VEHICLE UNSAFE. ONE EXAMPLE OF THIS ISSUE RESULTING IN THE VEHICLE LOOSING TRACTION OCCURED IN NOVEMBER 2015 WHILE GOING ON A CIRCULAR HIGHWAY ENTRANCE RAMP WITH THE WARNING LIGHTS ILLUMINATED.

IN JANUARY OF 2016 A SIMILAR INCIDENT OCCURED WHILE GOING UP A SNOWY HILL (ROAD CURVES WHILE GOING UPHILL) RESULTING IN THE VEHICLE LOOSING TRACTION AND GOING INTO A SNOWBANK.
