Does the EPA warranty automatically come with the trucks like the factory warranty?
It comes with every vehicle in the U.S. It's an EPA federal requirement that manufacturers maintain emissions systems for a period of 8 years or 80k miles.
I sure would like to verify this. I can understand emissions warranty covering it technically, but I bet Ram tell ya to go fly a kite.
And a quick phone call to the EPA would have Ram and that dealer fined. Though, to note, they are under no obligation to inform their customers that such a warranty exists. 9 times out of 10 people don't know any better and wind up paying for repairs that otherwise would be covered by the manufacturer.
My 05 Titan had cracked manifolds in 2011. Well past the factory warranty, but still within the EPA warranty. Nissan replaced the manifolds at no cost to me. A leak in the pre-catalyst exhaust is a leak in the pre-catalyst exhaust. The reason matters not.
