2016 Bighorn crew cab with 33k. Purchased about a year ago from a friend when it had 21k miles and the only issue I had was loss of coolant. Dealership replaced a hose under warranty and the problem reared it’s head on the next road trip. Back to the dealer and this time they replaced the EGR cooler still under warranty. No problems since. Just had the emissions work done on it today. Claim has been submitted and all documentation sent in online. Show me the money! 10 year extended warranty for all emissions related future work. Good to go. Fingers crossed because I love the truck.
