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.

I left my home on a 1300-mile round trip from ar to ky. About 100 miles into my trip while pulling an enclosed 16' trailer at 70mph on a flat 4 lane highway the warning reduced engine power and the check engine light came on. The reduce engine power warning went out, but the check engine light stayed on. During the next 550 miles the reduced power warning came on and went out about every 100 miles. I was able to continue to ky that day. The light went out the next morning. On 6 July 2020 I started home and both the check engine light and the reduced power warning came on after I had driven about 50 miles driving at 70 mph pulling the trailer on a 4 lane interstate highway after a few minutes the reduced power went out but the check engine stayed on, during the next 600 miles the check engine light stayed on but the reduced power warning would come on and go out at about 50 mile intervals. This continued all the way home. During the trip when the reduced power warning came on the truck would hold whatever speed the cruise was set at but if it tried to go up any incline the truck would not rev above 3000 RPM which caused the transmission to jump in and out of passing gear and you were unable to pass or even keep the speed up going up any type of a steep incline (hill). Since you had no idea when the light was coming on and the power was going to be reduced, I was afraid to pass anything or let any other vehicle get too close behind. I got the truck into shop two days later. When I picked my truck up, I was informed that the egr cooler had failed internally and was losing coolant into the exhaust system and had to be replaced. I did a search of the internet for other owners who had this problem with their truck and found lots of other owners who had the same problem reduced engine power and most were due to the egr cooler leaking and causing a loss of coolant.

Once while driving, the vehicle shut of with out notice. There is some hesitation occasionally while driving and has also stopped running while sitting still. Took it to a Nissan dealer and paid to have a diagnostics test and they said nothing could be found. I don't know if it's electrical or fuel components. No engine light comes on the instrument panel.

On 05-01-2020 I was driving back home on I-59 North and I lost the power steering, alternator and A/C. I continue driving because I still have mechanical steering control I get home and I noted the serpentine belt and the belt tensiometer was broken, I ordered and changed after repaired I was driving to work on 05-07-2020 and I notice the car is not working good, I check and 1 of the bolts from the steering pump adapter was broken, I take to the dealer and after a week and be talking with Nissan case number 40163453, with the car inside of the warranty they say the bolt is a hardware and is not cover by the warranty, also the dealer say is going to be expensive repair because they have to remove the radiator, I choose to do the repair by myself, I'm an aircraft inspector with 39 years' experience repairing airplanes. I fix in the best way I know, but this situation can cause a accident see attach pictures, also the adapter pump holes are little big of the diameter of the bolts with the vibration of the engine (diesel) can cause this bolts to be loose.

Yellow check engine light comes on and loss of power, truck will jerk back and forth like theres no fuel then will shoot off.this has happened many times with no light on.ive taken my truck to the dealer to be told the check engine light came on for def low and braking too many times. Driving normal and a red indicator light comes on with yellow check engine light and truck saying reduced engine power and I pull over and turn truck off for a few mins and everything is off. Truck many times wont go past 3 rpms.many times while driving I cant accelerate and no lights are showing.Nissan dealerships I believe dont know anything about this truck and is clearing codes without fixing the problem.ive asked to see the code list and was refused.recall on ECM same issues were happening and the recall was fixed to update ECM but the dealership actually fried my ECM and had my truck for 45 days trying to get it started. Same problems as before which I believe something else again is wrong with this truck.many Titan owners are having the same problem, dealership state they cant duplicate the issue which if they tried they would succeed but trying and having a vehicle only get 5 miles on while at dealership is highly suspicious.dealership doesnt fully listen.transmission has had a hard knock into gear since day one and was told that's normal for my transmission.I see the same problems being said by alot of owners and nothings being done about it. I've been having these issues since I bought my truck Jan 31 2017.

This truck is a diesel. Every time it goes into regen the cab of the truck will fill with exhaust smoke and fumes. It's so bad it will make you feel sick, and get a headache. I feel it's only more noticeable in regen but the problem is always present, due to the fact that when it sits idle eq. Waiting for wife in store that I will get a bad headache. I did not connect the two issues but it is more apparent when in regen due to a larger amount of exhaust being produced. This is a dangerous situation, I have been told by Nissan (2 different dealers it's normal and not dangerous) there is a case on file with Nissan motors regarding this problem. And I am aware of many people having the vehicle re-purchased by Nissan for this exact problem. I really like my truck, it has had some issues that have for the most part been resolved, but this is a health and dangerous situation that needs to be resolved. Since when is any amount of vehicle exhaust entering the vehicle ok" poor tail pipe design"

The vehicle stalls out when coming to a stop at intersection. Sometimes before coming to a complet stop and is dangerous when it happens at mid crossing point of intersection.

During normal driving the check engine light comes on periodically and the engine goes into limp mode for no apparent reason. There is no acceleration and you typically cannot get above 15 mph. Today was the fourth time I have experienced this issue. The dealer has a new turbo on order but is not confident this will cure the issue. The previous episode nearly caused an accident by a distracted driver when I couldn't accelerate through an intersection left turn with plenty of space and time. The accelerator pedal has no response to the engine and there is no prior warning. The check engine light may or may not illuminate. Today the engine went into limp mode when acceleration from a dead stop at an intersection. The truck never achieved more than 10 mph and when I removed my foot from the accelerator the engine died. Luckily I was at an intersection with traffic lights and it was downhill so I could coast through the intersection to the shoulder. I placed the truck into park and restarted the vehicle without further incident to my home.

I'm writing to make aware of the delay in acceleration of my 2016 Nissan Titan xd. On several occasions I have either tried to pull into traffic or make a left hand turn and have had no power due to a delay in the turbo kicking in. It's quite scary. Hopefully this can be addressed and corrected. Thank you, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Upon purchasing this vehicle new from the dealer, a strong diesel exhaust odor was noted within the cab of the truck. After bringing the vehicle back to the dealer with the complaint, I was told that the vehicle simply needed a software update. After receiving the vehicle back from the dealer, and having the software update performed, the vehicle still produced strong diesel exhaust odor within the cab of the truck. Since that first attempt to rectify the issue, I have brought the vehicle back to the dealer on multiple occasions (4+ times). No dealer has been able to resolve the issue and get rid of the diesel exhaust odor within the cab of the truck. Finally, I lodged a complaint with Nissan Consumer Affairs. I have been working within them for over 2 months now, but they are little help. They keep delaying additional expertise on the issue and have denied my claim for a "buyback", asking now that I replicate the issue with a 3rd Nissan dealer. I have little confidence in their ability and/or willingness to resolve this issue. In the meantime, I am driving the vehicle and potentially breathing in unsafe levels of carbon monoxide (or other toxic gases associated with the strong diesel exhaust odor continuing to be released into the cab of the truck). At one point last week, I had to stop driving the truck entirely, as the headaches associated with driving the vehicle did not warrant continuing to use the vehicle for regular transportation. The diesel exhaust odor is very strong upon cold start-up and continues to be emitted while the vehicle is being driven (albeit not as strong as upon start up). Regardless, the odor is prevalent within the vehicle and I believe that driving the vehicle introduces a significant health risk to both the driver and any passengers.

I merging into highway traffic and lost most all engine power. I pulled over onto side of highway and looked under hood and under truck for signs of why. I saw a waterfall of fluid gushing off of transmission case. Smelled diesel fuel I turned off engine and called a tow truck. I had several gallons of fuel that had poured out of injector that came loose and over engine and transmission. Truck was towed to dealers. This could have been a deadly incident in two ways for passengers and other drivers on highway. Temperature was 90 plus degrees and sunny. Very hot.

- Taylorsville, KY, USA

I have taking my truck to the dealer so many times to be told the def system gauge can not be fixed. All the trucks have this issue. I applied for the lemon law and was refused. Now the latest was the coolant was causing the truck to loose power because as I was told by the dealer it's normal for it to evaporate a half a gallon in 18 months. Seems a little strange to me. In the meantime I still have to pack around def because I never know how much I have. The truck has many issues. Also the running boards was never installed on the truck. The dealer actually charged me for a set which is not the oem set then reimburse for the cheaper set.

Coming off a highway at around 50 mph the yellow check engine light came on and the engine started making a "popping" sound and jerking as if misfiring. Connected a code reader to truck and 5 issues were found. Engine codes P0544, P244D, P242D & P242C were listed stating "exhaust gas temp sensor" and "exhaust temp high for dpf" along with code P0204 "number 4 fuel injector circuit open". had vehicle towed to dealership and the diesel mechanic stated the "graved connector F131 on cylinder #4 was at fault and that the connector "spread terminals were causing poor contact with injector". stated the engine control harness (wiring harness), needed replacing. Vehicle had only ~62500 miles on it at the time.

When accelerating the vehicle gets stuck at apx 30rpm. It will stop complete acceleration for apx a minute and then will pick up speed. This continues to happen and has almost put me in two accidents getting hit at intersection and entering on to a ramp, and stalling in traffic on a busy street. I have reported to West Texas Nissan and corporate. The vehicle was returned once to me without correcting it and it did it again with a mechanic test driving with me. It is currently in dealership again for the last 40 plus days with them saying they cant detect what it is. I would mention a new engine had to be replaced on this truck with in a month of new purchase. This issue is a safety concern yet Nissan continues to say they cant pick up a code for it. I have videos of it happening and a Nissan mechanic that drove it with me.

The contact owns a 2016 Nissan Titan. While driving at various speeds, the fumes from the diesel engine penetrated inside the vehicle and made the occupants of the vehicle dizzy and sick. There were no warning indicators illuminated. The vehicle was taken to grand strand Nissan (4701 us-501, myrtle beach, SC 29579, 843-236-2191) where the technician diagnosed that the failure was caused by the diesel engine. The failure recurred several times and, after five attempts, the technician was unable to repair the failure. The manufacturer was notified and determined that the failure could not be repaired. The manufacturer made three different offers to the contact, including a buy-back, but the contact did not make a decision. The failure mileage was approximately 800.
