2013 Coolant Leaks
Just posting an FYI, I know other users have had similar issues on '11's and '12's but figured another thread couldn't hurt. Bought the truck brand new from dealership two months ago, put 1300km on the truck and noticed a pink colored fluid on the driveway under the front of the truck (under rad or front part of engine). Just got the truck back form the dealership and the work order states they found fluid leaking from lower rad hose assembly bonded areas. Also found coolant drips from block heater screw. Replaced lower rad outlet hose, installed worm gear clamps at surge tank and heater pipe, vacuum filled cooling system to prevent air locks. Ran, checked, washed down affected ares, re-checked for coolant leaks found none. Replaced engine block heater due to dripping coolant from screw, checked for leaks, found none.
Sucks having a warranty claim on a brand new vehicle, but hopefully this will be it for a long time.
