Extremely heavy steering causing excessive driver fatigue making it difficult to maintain control of the vehicle at highway speeds (up to 70mph). Dealers unable to reproduce, likely due to it being cold outside when I had time to go. The hotter and dryer the roads gets, the better grip the tires have and the worse the heavy steering gets. It is significantly heavier than my old car at higher speeds and that car has no power steering. My arms are very sore after 30min - 1 hour. Mazda refuses to admit this is a significant safety issue. It gets worse when the LKAS activates at least once (too heavy I am veering around in my lane)
