CEL and DEF problems

First time posting and I need some guidance from the forum. I purchased my new Laramie Eco Diesel and it was delivered in August 2014. In September with 4000 km I got my 1st regen in warmer climate. Beginning in Dec when colder temperatures arrived my 1st CEL light came on and dealer replaced oxygen sensor, 400 km later CEL again and this time a week at dealership awaiting at CAT converter, at 11,000 CEL this time a clogged DEF nozzle, 500 km later CEL this time a new DEF pump after a week at dealership and thisa past Monday after only 300 km CEL and I'm informed I need a new NOX sensor and a DEF injector which is on back order and no date for delivery. Meanwhile truck sits at the garage and they gave me a **** NOX as a loaner. I a quickly loosing faith in this truck as I had hoped at 63 it might my last vehicle and went all in when purchasing. I've read many comments about how cold weather can have a very negative effect on these systems, in northern NB cold weather in winter is an every day occurrence like regularly -10 to -20+ and I am wondering if this was the right truck for this climate. I am not very mechanically inclined and maybe that was a mistake purchasing new technology so early in the came. I do love the truck for all other aspects.

Sorry to here about all your troubles. This has been an extremely cold winter again this year and I personally can't wait for it to end. I have had many nights down in the -20C range lowest was -29.

I also bought mine in august and have absolutely no issues at all, and like you I'm all in for my last vehicle and it looks like it will be.

good luck with your truck, I got rid of a 2013 pathfiner, becasuse it was a piece of crap, but not as bad as your saying.
