One day, and 80miles, after buying the truck (@~49800miles) left for work on 25deg morning, turned the corner to go up a hill and truck triggered solid traction control light. While climbing the hill truck would not shift out of 3rd gear. Restarted truck at top hill and continued to work with no issue. Upon leaving work same day, pulled out in to traffic and truck starting bucking due to its inability to Rev past 2500rpm this time triggering solid check engine light and solid traction control light. Since then truck has solid check engine light upon each startup and will not Rev past 25-3000rpm without triggering traction control light. Truck shifts fine if sub 2500rpms are maintained but will not shift past 3rd if rpms are exceeded. Had Autozone scan check engine light same night resulting in codes p0335 (crankshaft position sensor A) and c1130 (right rear height sensor out of range). Continued to drive truck to/from work for 1.5weeks. Though truck was bought without expressed/factory warranty, dealer paid for oem crank senor that I installed with no result. Truck has been at local Nissan dealer for diagnostic work for half week so far waiting on backordered wiring harness to that sensor with repairing dealer suggesting that may not cure it. Repairing dealership also replace negative battery terminal clamp hardware as it could not be tightened. My carfax had record of replaced crank sensor and upon further investigation also had some wiring harness replaced under factory warranty. Unfortunately, this suggests to me it could be a systemic manufacturing quality issue. Have not found any TSB regarding similar issues, atleast for 5.6L engine.

My t2017 Nissan Titan XD started having the check engine light come on when I am in full throttle on the highway. Eventually it states a warning "Engine Power Degraded". This caused me to pull over to the nearest dealer, but the warning clears when I slow down. Nissan dealer told me I would have to leave it for 2 weeks for a proper inspection since they lost the diesel mechanics, probably since they stopped making diesel trucks. They ran diagnostics on it at least and told me it was low voltage. Now my truck is stuck in the driveway and won't start.

I have to get it towed once they get a diesel mechanic. The truck sits and chugs when I crank it, I can tell the batt is exhausted. I don't want to buy a new batt because I want to know what caused it since it should have recharged during heavy driving (highway), but Nissan cant seem to get anyone to look at it. I am going to be stuck renting a car. I called Nissan and they said since I am 3 years in, my warranty has expired and they will not pay for my rental. Unbelievable. I have had nothing but issues with this truck and paid tons of money for it, now Nissan ignores me.
