Vehicle towed to the dealership where I purchased the truck and diagnosed with engine failure. Multiple bearings went out sending metal fragments throughout the engine. Vehicle had 28,500 miles at time of failure. Dealership had truck for roughly a month to perform complete engine replacement. Truck currently has 32,000 miles on it and seems to be running okay.

We bought my wife’s vehicle in May of last year and are unable to move out of it due to being in negative equity at the moment with that vehicle.
