After loading our boat at a reservoir and prepping the boat on the trailer, I started the Durango to leave the lake, and the engine was knocking. A guy from the marina came by and said "it's knocking isn't it, that is the third Dodge this summer. After having it towed to the nearest dealer and waiting a week for a diagnosis I was told that there is an evacuation canister mounted on the frame rail about mid-vehicle. If the vent to this canister gets in the water it will suck water into the intake of the engine. The engine had hydro-locked and was destroyed. I was told that even though we only had 37,000 miles on the vehicle, Chrysler would not warranty this because it was considered submerged. 6 weeks and $7000. 00 in repairs and rental car fees, we have finally gotten our vehicle back. I was told by the mechanic that getting in water up to the hubs of the rear wheels, I would be at risk of this happening again. I am not sure that it was even in that deep when it happened the first time. I am going to get rid of this vehicle immediately.
