I am having trouble with air ride suspension on my 2014 RT Limited. When just starting up I can set the suspension with the taggle switch up or down. Once on the road 4 or 5 miles the bar indicator shows "manual". Had switch changed (dealer thought intermitent problem) and traveled about 6-7 mile and "manual" back. Continued 40 miles, atopped to get a drink and gas up and display came back on (maybe cool down?), then less than a mile back to "manual". Any suggestions would be appreciated.

Thanks, Bamm Bamm
