2017 Nissan Titan problems

“I was droving down the road with the cruise control set at 70MPH, when all of the sudden the engine lost power and stopped. It did not have a check engine light or anything on the dash to indicate that there was a problem. I coasted to the edge of the road where i attempted to restart the vehicle, but it would not even turn over. I had the vehicle towed to a repair shop where I was informed that they engine was locked solid. The mechanic suspects that they crankshaft is broken, but the entire engine will need to be replaced.”

“Purchased a used 2017 Nissan Titan XD Pro-4X 5.0L diesel on 3/8/25. Left the dealership and only made it ~10 miles down the road before the check engine light came on and there was a loud knocking noise. Immediately turned around and went back to the dealership. After diagnosing it I was told it was a fuel injector and that they were replacing it. Received the truck back ~3/20/25. This truck is not my daily driver but the few times I have attempted to drive it the check engine light keeps coming on and I'm getting a message about the REGEN. On 5/28/25 I had the truck towed to my local Nissan dealership. They diagnosed it and although there is still a code for the same injector coming up they said the issue is the wiring harness and quoted me $7000 to repair and it's not covered under my powertrain warranty. After research it seems like this is a common issue in 2017-2019 Nissan Titan 5.0L diesel trucks which will cause the crankshaft to break if not fixed. I am super frustrated that after less than 3 months of ownership I have an undrivable truck requiring thousands of dollars in repairs.”

“Truck was fine and then went to pull out in traffic and it would not shift past 3rd gear, was dangerous because traffic was moving quickly and no lights appeared on the dash but the transmission just stopped shifting past 3rd. Had to limp it back off the road which was scary because people were traveling at higher speeds than we were able to even though just 2 minutes prior we had come from that same road and we were traveling just fine. Was told by dealer that the valve body went out and is costing $3400 to replace, no metal shavings found inside the transmission but this incident almost caused a wreck and is costing a serious fortune. Seems to be a serious and common issue from the research I’ve done, unfortunately it’s something that’s just becoming known because I would have never bought it expecting danger and expenses like these.”

“Received a recall for my vehicle. Recall was pd128. Took vehicle to dealer to have recall serviced on vehicle which was for a pm sensor and reprogram the emissions control module. After recall, DEF system error code and reduce speed to 5mph showed up on truck. Went back to dealer to explain issue after the recall. They ran codes and thought it could be the DPF filter or EGR without thinking the recall could be to blame. Went to another mechanic and did a DEF system check and found no issue with system but a miscommunication with the NOx sensor. Had NOx sensor replaced and a week later had same DEF system error come on but was more intermittent and would clear on its own. Checked codes and found said miscommunication with the same NOx sensor that was replaced. Went back to the original dealer to explain the issue and believe it was due to the recall reprogram. They did a diagnostic and spoke with their own techs and said their campaign recall repair revealed a concern that was present before but did not have detection sensor or the logic to determine the issue and recommends DOC/DOF to to replaced. Contacted Nissan about the issue and if replacement would be…”

“Truck has been diagnosed and the airbag sensor seems to be at fault. The sensor light is blinking and if there’s an accident the airbags will not deploy. This is a huge liability and safety concern”

“The vehicle is available for inspection immediately by all parties. While driving down the highway, the truck started a vibration, without any warning indicators. The vehicle was taken to the next travel center truck shop. The writer acknowledged the vibration like a misfire, but no codes were present. He recommended another shop or dealer. A detour was made to the nearest Nissan dealership. On the way, the truck stumbled with a violent vibration and shut down on the road without warning lights. There was a complete loss of power from the engine on the highway, giving way to the risk of being hit by other motorists and blocking traffic. Since the engine shut down, there was also a loss of power steering, giving high risk to the possibility of an accident. The truck was unable to restart. The vehicle shut down in the middle of the desert, exposing my family to unsafe environmental conditions. The truck was towed the remaining way to the dealer. The next business day, the technician got the truck started and verified the concern. The tech requested additional time for teardown which was approved to remove the oil pan for inspection. I was quoted over $37,000 to…”
