So I have a 24 Colorado and I went fishing loaded my kayak in the water on a trailer pulled out parked everything fine. I could tell a storm was rolling in so I fishing the bank by the truck if all else fails I can just pull the boat on the bank wait on it to pass. I did that not even 40 minutes as I was fishing by the truck I get back in start it and it says service 4wd now the dealership I bought it from is trying to say rodent damage. I seen no rodents around and I was 30 feet from the truck tops. Here’s the kicker talked to him about it being covered by warranty and everything was good but as I’m going out the door says unless it’s rodent damage. Kinda suspicious to me. But has anyone had a service 4wd in 3rd gen?
