Upon landing on the centerline of runway at ZZZ the airplane made an uncommanded turn to the left. Even with rudder input and braking I could not keep the airplane on the runway. The left wing clipped the 3;000 ft. remaining sign. Winds were 340 (degrees) at 12 (knots) gusting to 19; (pretty much straight down the runway). Inspection of the airplane showed that during the excursion the nose gear was completely sideways such that the 'Goodyear' was worn off of the sidewall.I do not have 'lazy feet.' I believe that my quick response to the airplanes movements prevented more damage as I was able to stop the airplane just off the runway. I have been flying PA46 airplanes for eleven years including 300+ hours in the Matrix and 1000+ hours in the Meridian/M600.There is no good explanation for the airplane's diversion. Subsequently I found out that there have been 5 other M600s that have experienced no less than 7 similar excursions. I and others believe there is a material problem with the PA46 M600.
PA46 M600 Pilot reported loss of directional control during the landing roll out and exiting the pavement.
