No issues with the cooling system on my Limited yet, either. Except for dropping a saddlebag, no problems with the bike at all. HD made good for a new saddlebag.
A couple other recalls for things that didn't surface as problems.
Bought my bike in Sept of 2013. After the first thermostat went they received the replacement which was also bad. Then the radiator cap was bad and I forgot the other bad part. I checked the new part and it looks diffrent from the last one. I think they finally got it.
They finally figured out what was wrong. My coolant pump was sticking. It ran ok most of the time, however every now and then it would stick locking the hot coolant in the hose. This caused the thermostat to overhear and the joint would let go. They replaced the pump in April and 5000 miles later it is working fine. The pump works when it should and everything is ok. I've ridden in a lot of 90+ degree weather, several parades and all is well.
Well, 16,500 miles, in two years on my 14 Limited. Never had a Coolant issue at all.
When it's hot out, after a ride, I do on occasion manually turn the fans on, when I get it home in the garage and let them run a bit.
