Have a 2012 Sport, non super charged. Getting a yellow suspension light that stays on and then sometimes the red light will come on and say 30 mph. Ride height is not effected according to the 4x4 info screen. This light or warning seems to be hit or miss. Sometimes right at start up the yellow warning will appear.If i turn off truck and restart the light will dissappear. Stoping the truck and restarting always, at least at this point makes the light go away. There is no rhyme or reason it seems for this warning to apperar. Also the truck will raise to extended height and return to normal but will try to lower to access height but return to normal height.
Any thoughts on what could be causing this or where to start to fix the issue will be greatly appreciated.
Many Thanks
Dave
