I still have not purchased either truck. The dealer called my yesterday on the 2013 and told me it can't be certified since it is from Canada. But they still did the inspection for sale as if it was certified. So, I called a local dealer to run the vin and give me any information on the truck. Looks like a new front differential was installed in 2015, gauge cluster, gas tank float system and evac control system, air bag sensor under recall, new tail light bulb, new tires, new skid plates. All of these items were warranty things done to the truck. So my question is once the differential has been replaced do those issue come back up or are the replacement differentials stronger than the 2013 design? Not sure why the skid plates would have been replaced? Also my 2005 pathfinder seemed to always have gas gauge/evap canister issues. Is this a common thing with the Titan? I really really like the look of the Titan and want to pull the trigger, I am just nervous with the issues I read. A buddy of mine has a 2004 with 132,000 with very little issues.
