Re: 2014 Front LED DRL not working...
I also just verified that on mine, they turn off when applying parking brake, even in Drive and moving....
so to summarize, on a 2016 Summit, with the DRL box checked in Uconnect, The LED DRL's are ON as long as the engine is running and the parking brake is OFF. If the parking brake is engaged (even to the first click), the DRL's will be OFF. Shift lever position makes no difference.
