I had a check engine light for catalytic converter bank 1. Added a cleaner to see if that would help - instructions mention run 1 - 2 tanks of gas after adding, so I did that, it took a while since I dont use the truck as often. The light did not clear so I was planning on bringing it in. I was on the highway and the check engine light starting flashing and power loss occurred. I limped off the highway and got it towed. It had 3 codes on check engine light. Other than the check engine light, no warnings, messages, nor symptoms appeared or occurred prior to the flashing check engine light. Got to Mastria Nissan, they looked at it for not long (morning) and said the engine and other components were junk. Presented a $27,000 bill. They did not tear it down nor illustrate what went wrong. Police nor insurance inspected the truck. Safety was compromised as it died on the highway where everyone was doing 70 plus. Had to limp off the highway as the pull off area was very busy and not spacious whatsoever. Truck has 28,000 miles on it and was planning on the 6th oil change. The first 2 were done at Nissan and I changed the oil myself other times. Drained oil had an appropriate volume. No oil has ever leaked. I have order history on oil and have the last oil change oil in my garage still. I filed a claim with Nissan corporate, I have emails with them, but i got a denial over phone on January 5th. They claimed they dont have enough service history and im 6 months out of warranty. Also, on the call, they refused to send the denial by email or regular mail.

While operating vehicle within city limits the engine failed and the vehicle was unable to move under its own power. While slowing down, the vehicle's check engine light came on and the vehicle immediately lost power and would not turn over. The vehicle was towed to a mechanic's shop and after reviewing the problem and performing an inspection, it was determined the engine crankshaft seized.

Check engine light went on and the Truck went into low power mode. Took it to an independent service center and it was no longer throwing the code. It happened a couple more times, took it to the dealership and the diagnostic was: Setting in ECM., Actuator is Binding causing DTC and vehicle to go into Reduced Power Mode. This seams to be a very common issue in Nissan Titan XD's. Maybe should be a recall? A very pricy repair for a vehicle that only has 45000 miles on it.

2019 Nissan Titan XD Diesel 153,700 miles. Driving 70-75mph on Texas highway and felt a vibration when I pressed on the gas pedal. Started moving over to exit due to power loss when a slight puff of smoke came out. I pulled over in a safe area and shut the truck off. There were NO Warning lights on the cluster. When I stepped out a small puddle of oil had already started to form under the truck. Open the hood and the passenger side engine compartment was covered in oil. I noticed oil formed on the license plate and was dripping out of the exhaust pipe. Oil had dripped off the under carriage from front to back, large amount formed under the vehicle after sitting for 1hr. We towed the vehicle to the local Nissan dealer and the result was a broken crank and possible transmission failure. I have reach out to Nissan corp to file a complaint as well. This vehicle has never experienced any significant issues, Nissan had no history prior to my reporting today. I have owned the vehicle since 2019 when I purchased it with 6k miles on it. Nissan has quoted me $32,660.63 for repairs (engine/Trans replacement), this is almost what I purchased the vehicle for in 2019.

I stopped to get diesel and pulled onto the interstate. Within 2 miles of being on the interstate, the engine felt as though it downshifted, lost power, and stalled in a construction one lane zone with no way to get out of traffic. The engine would no longer turn over and the truck would not start. This was a danger, not only to me, but to other drivers on the interstate. Had taken 90 miles away to a certified diesel nissan dealership who said all of the fluids were good and the motor was locked solid. It was not covered by warranty ans was estimated to cost $32,000.00 to replace motor.

I was driving with the vehicle operating perfectly normal. I turned onto a highway and was accelerating when all of the sudden without any warning lights or alarms the vehicle began to shake vigorously and lose power. I was almost rear-ended by a 18 wheeler trying to get to the shoulder. I had the vehicle towed to a nissan dealership that had it from 8/25/23 through 10/24/23 where they found that the engine crankshaft had failed. Due to this being a common issue the engine was replaced under warranty. The vehicle operated fine upon receiving it but now has check engine lights on. I have also lost all confidence in this truck as I was almost in a accident because of the failure. My resale value has completely diminished as with these nissan titans in general because of the known issues. This was also a pickup used to get back and forth to work and was expensed through my company I work for, so when it was in the shop for 2 months with no loaner I had to buy another vehicle as well as get a company vehicle and lose the expense amount I was receiving from my company for using my vehicle as transportation. This vehicle failure has made me lose all faith in this truck that I can safely get from point A to point B.
