I purchased my 2014 used a few months ago. Noticed the coolant reservoir was low and topped it off. Smelled the coolant standing next to the truck. After researching i found this post and TSB. I went to the dealer where I purchased the truck from and while having the transmission fluid flushed asked them to check the radiator due to coolant loss. I mentioned this TSB. The rep called me back later that day saying he researched the coolant loss and confirmed it was due to the thermostat cycling and that it was fully covered under a special warranty. I just picked it up today with new radiator and thermostat. My bill was $0.00 including a loaner truck while they worked on it. I am very happy with the service and grateful it was covered under the warranty. Truck has 90k miles on it.

My 2014 makes this same whine noise. I bought the truck used and did not really notice the whine until i began driving it regularly. It is constant at low speeds cold or hot. I initially thought it might be the transmission but after this video it seems like it could be the engine. I feared it was a bad alternator or steering pump etc... Engine is running strong. I am about to change the oil so we'll see if that makes a difference. Anyone find out where the noise is actually coming from?
