Issues with turbo actuator. The check engine light stays on and I've taken it to Nissan multiple times to diagnose but they want to change me diagnostic fee every time and still can't tell me what the issue is. The truck loses power while driving without any warning and goes into limp mode where it will not go past 5-10 mile per hour. According to boards and Nissan this is a very common problem with Nissan Titans with Cummins that Nissan has failed to fix with recall. This is a huge safety issue and could cause loss of life as it has stopped on me on the interstate multiple times. Please fix this issue asap as it's been reported over the course of last few years and someone will lose their life over this huge issue.

Connecting rod cap on cyl3 came loose and drop in bottom of oil pan, and Crankshaft broke and seized up engine. Transfer case won-€™t shift into 4wd

The turbo actuator failed twice. I have yet to replace it a second time hoping there would be a recall. I spoke with two dealers and they tell me it is a common problem on Nissan titans with a Cummins engine. The check engine comes on and then the truck goes into limp mode. It does not want to go past 5 -10 mph. It goes away after the truck is turned off for 15 minutes. Then after a week or two it comes back. If I do not turn it off for 15 minutes the truck turns itself off.

Faulty Turbo Actuator Vehicle would stall stall without check engine light in traffic. I could Cycle the key and vehicle would run again no check engine light. It did this at least 4-5 times in traffic and on freeways. Nissan also is not providing support as actuator was on back order for over 6 months. Vehicle stall I f with no warning and cycling key to restart. I replaced it and once had it repaired and vehicle still runs poorly.

My Titan XD has just over 28,000 miles on it. There is a long acceleration delay. I-€™m not sure if this issue is known. But if there-€™s a recall for this problem please let me know.

Vehicles engine suddenly and without warning began knocking while crusing down the interstate, within 30 seconds of the sudden knocking the engine was locked up on the side of the road. After reading i have found thousands of other cases just like mine where there cummins 5 liter diesels have suddenly and without warning locked up while traveling down the road. All maintenance was done on time by nissan technicians. Milage for my specific instance was 101,056. Nissan refused to warranty and dealer ended up out of pocketing most of the repair. And Nissan continues to ignore that there is a serious issue with these engines, and after doing more research i have found litterally thousands of cases just like mine, and anywhere from 1000 miles on up through 150,000 miles with some instances happening up to 5 repeated times before the vehicle reaches 100,000 miles. The repair itself cost upward of $23,000, and dealerships and technicians seemly know nothing of said issue even though a quick search online shows case after case of peoples nissan titan diesels unexpected locking up while traveling down the road and in some cases causing the drivetrain to lock up as well suddenly and abruptly stopping there vehicle, potentially causing an accident. More often than not though nissan is leaving these customers like myself high and dry on the side of busy interstate while they continue to hide the fact that there product is defect and potentially unsafe. I was fortunately to have a great dealership that took care of me and got me off the side of the road, but many arent. In most cases including mine these vehicle display a crank position sensor code, and then shortly there after the crankshaft breaks in half and often times sends large pieces of metal flying out of the engine block shortly before locking up completely. I was fortunate and mine did not throw large pieces of metal out but many are not, and these large pieces of metal often pierce the vehicles tires and those behind

Crankshaft broke while on interstate. Lost all power from engine and to exit to side of road immediately. Truck is at dealership and was giving news of needing engine replacement at 84k miles. Service light on for boost control system but was told that vehicle was drivable.

The truck goes into limp mode without warning. The cause is a faulty wastegate actuator that is now on it-€™s third revision. The exhaust gets clogged dur to improper mix ratio and puts the vehicle into limp mode which will only go about 10 miles per hour. This can happen without notice and could cause death or injury while merging into or across traffic. Part replacement not available and no status when it will be available. This is a serious issue that needs addressed die to no warning before disabling full power. I-€™ve had several near misses due to this.

- Winchester , OH, USA

The crankshaft broke while I was in the middle of a two lane highway. I was unable to move any further and I was a huge traffic liability for everyone that passed. My children were in the vehicle and we were really worried about their safety. The vehicle was inspected by the manufacturer and my insurance. There were no warning lights or anything to let me know I might be having an issue.

Hello, I have purchased this Titan XD diesel 3 years ago from Nissan Dealership in MD, (Anwerpan Nissan). That dealership informed me before It was an issued with turbo chargers and replaced them. Over the 3 years I was maintained this truck with proper oil changes and other service. I have outfitted with camping (ovelanding equipment), so this summer in July we went to camp in Upper Peninsula, MI, when the engine just stopped working right on hwy, and it's lucky enough no accident happened and we are be able to roll on side of the road. I have towed the truck to Garber Nissan, MI, they have troubleshooted engine and said it will need a full engine replaced as bearing spun and may be broken crankshaft. I found out later from forums and Facebook it's a very common problem with these engines. It's very dangerous, if the truck was pulling a load and engine locked up, and trailer swing around. Nissan NA has refused to cover this repairs. The repairs is about $17,000 to $20,000 plus. Cummins engines for the Nissan is pretty much failed every one from 2016 to 2018 years of production. The truck has 96,000 miles and warranty expired in 02/19/2021 The Nissan NA representative is [XXX] ph. [XXX]. Thank you [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Engine loses power, slows down to a creeping 5-10 mph during peak hour traffic or turns-off completely. Instrument panel reads exhaust filter overload/reduced speed. Afterward, vehicle will not start at times or will start but resumes 5-10 mph speed of travel. Had manual reset performed; only 44 miles later to have same engine trouble beset the vehicle again.

Immediate recall needed on all Nissan Titans with limp mode for def expiration. Deadly consequences possible and not avoidable. I have recently discovered that the Titan is a deadly vehicle in several ways. Most recently I discovered the fact that def fluid ages to the point of causing the vehicle to go into a limp mode of 5mph with no disabling the limp mode. Unsuspecting diesel owners have no way of knowing if the def they purchased has expired or the def in their tanks has gone bad. If the vehicle is in an area that has drastic climates such as sub zero or extremely hot, driver and occupants of vehicle may die of exposure. There is no warning for the def failure for impending failure of the emission system as I have just experienced. I believe that not making Nissan and others to not recall this dangerous built in child killer would be a tragic mistake by the safety commissions.

On a daily basis the diesel engine has a hesitation from both a stopped position as well as low engine RPM that causes safety concerns in traffic. Reported issue to Nissan with no help.

While traveling down highway the check engine light illuminated and I lost all power. I had to get to the side of the highway fast before I got rear ended. This vehicle is extremely dangerous. I purchased used with 10,000 miles on it and this is the second time the engine has lost complete power with no advance notice. First repair by Nissan dealership was blown valve and turbo problems. 8,000 miles later the turbo is throwing error code P2662. This truck is heading towards lemon status with the terrible 5.0 V8 and it's no wonder Nissan stopped offering the diesel option. Other problem the rear door exterior panel rattles when at 45mph or higher and is quite annoying for a supposed platinum model. I'm beyond disappointed in this vehicle and it should be pulled off the road before someone gets seriously hurt or killed from instant loss of power while in motion. I'm in shock that this diesel motor isn't under investigation. Nissan doesn't have adequate diesel technicians to address these problems. Nissan or cummins need to recall this truck immediately.

Vehicle was in motion when happened. The vehicle was already in movement for couple of hours. It have double diesel filters separator so this issues not supposed to happens. Not towing or anything just traveling true states.

There are diesel exhaust fumes coming into the cab while the vehicle is running. There is no difference whether the air conditioning is on recycled, fresh, or if it is off completely. The smell is overwhelming and does not go away even with the window being rolled down. The fumes also come into the cab whether the vehicle is stationary or in motion. The fumes do not increase nor decrease depending on the speed you are driving. The fumes are constantly there, at the same smell.
