I have a 2013 F450 6.7L diesel with just over 50,000 miles on it. I have had several issues with this truck since we bought it new. The turbo had to be replaced along with the starter all repaired by Ford under warranty. I have had it back at the Ford dealer where I bought it 3 more times for just plain running rough and losing power. They tell me they have cleared some codes and it should be good to go. When it happened again they replaced some tube that is connected to the turbo. This all happened with 30,000 to 37,000 miles on it. On 8/17/16 going down the road and the truck starts to sputter and the check engine light along with the wrench light come on and the truck just dies right in the road. Luckily some really good person came along that could at least pull me off the road. I had it towed to the a local ford garage and a week later they tell me it is the exhaust filter needing replaced and Ford will not cover this or any part of the $4100 to get it running again. I have three Ford Super Duty's for my business all under 4 years old and only one is running.
