The boldness got meverything at the dealer
 So this truck was purchased as a dual use vehicle. Needing a truck to handle the day to day business and when needed be able to tow big loads. Now driving it quite a bit it's been in the shop 4 times already. Right off the bat the engine acceleration was terrible, to the point it almost caused an accident trying to merge with highway traffic. In the mileage put on its used roughly 6 gallons of def fluid. Nissan informed me the engine adds fuel to try and burn emissions "soot" then if that fails it will use the fluid. I've seen the truck get 17-18 mpg under certain circumstances. I've had the truck back just to verify there was no emission or driveability issues.                                                    My recommendations? I would only recommend this truck if your pulling huge loads all the time. Anything else your wasting huge amounts of fuel.
