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.

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.

Our 2016 Nissan Titan xd was idling on a level carport with the parking brake engaged. No one was in the cab of the truck. I was unloading tools from the back of the truck. After about 5-7 minutes, while I was standing in the bed of the truck, the engine revved and the truck began to roll very slowly backwards. It rolled over a small concrete bump (intended to prevent cars from rolling off the carport), down about a 6 inch step down, across another 10 feet or so of concrete and into the brick wall at the back of the carport. I did not have time to safely jump down, open the truck door and engage the brake. The total distance the truck rolled was less than 10 yards. The tailgate of the truck was damaged badly when it hit the brick wall, but it helped to stop the truck. When I got into the truck to drive it back up onto the parking area of the carport, the parking brake was still engaged. I disengaged it to shift into drive. We have had issues in the past with the engine revving and extremely hard shifting between gears. There is also a heavy smell of exhaust inside the cab of the truck very often. The smell is strong enough to cause headaches. We usually have to crack the window when this happens. It happens intermittently, but often. I am not sure if what happened today was a brake problem, engine problem or transmission problem, but this is an extremely concerning safety issue.

Fuel tank gauge keeps bobbing back and forth, the digital range estimate is giving false readings leading to me running out of gas twice, and I get low fuel warnings even with the tank half full.at times the avg mpg would indicate between 15 and 23 mpg and the drop to 9.5 within 30 mins.

When trying to accelerate we put the pedal to the floor and truck will not move at all for sometimes up to 5 mins and that's with us trying to get the truck to go. We have almost been hit several times and we have small children that rides in the truck. We smell fumes in the cab in which I have asthma and again small children which is dangerous to smell. Shifts hard and not always the same, either takes longer to shift or shifts quick. Very jerky when in traffic. The day we got home with the truck we heard a grinding noise when pressing on the brakes.it happens random like the no acceleration. On freeway when accelerating and slowing down back to accelerating there's a horrible lag.our gauge doesn't match with what mikes we have left in the tank.when I go to the dealership they tell me there's no way and that I must be imaging it.this is our only vehicle and I dread putting my kids in the truck.our lives and safety are at risk.scared dealership will act like they checked the problems but really didn't.consitantly having to refill def which a friend said it shouldn't drop that fast. Our fuel mileage has gottten worse since we had it. Dealership wouldn't cover our windshield that cracked out of no where even though we paid for that particular extra option. Dealership lied about it all including our warranty which they talked us down to this truck. Also when turning into a spot or on a street the truck makes a weird noise and the wheel only turned up to 3/4 of the way. Also when starting sometimes it takes the truck longer to start up.

Purchased new 2016 Nissan Titan xd had severe downshift problem where vehicle would shift so abruptly it would feel like you slammed on brake pedal. Today while turning left from stop light a gas truck in first lane failed to stop at traffic light. I hit the accelerator to pull away and no throttle response at all. Had the driver of the other truck not brought his vehicle to stop injury or death would have surely resulted. I've owned nearly 100 new cars of all makes models types etc and have driven without an accident for over 40 years. I've never felt more unsafe in a new car and I've contacted dealer who acknowledged this has been widely reported problem with this vehicle! once again car manufacturers would rather wait until someone dies than fix the problem!

Bad transmission, slipping and erratic shift, at dealership 30 days still no answer about fixing it. Power steering too hard and makes noise when turning turbo is making noise. This is diesel engine with diesel exhaust fluid, not working properly, doesn't burn any def, it is requirement on all diesel engines to have this exhaust cleaner.

- Muskego, WI, USA

Little to no throttle response 3-5 second delay. Speed from 15-35 transmission issue as well. Call Nissan they stated they have known about this but have no fix. I fell this is a huge safety issue! no acceleration when need?

On November 22, 2016 I am driving down the highway and my Nissan Titan xd turbo diesal truck had a major loss of power and a warning light came on my dashboard. I pulled to the side of the road immediately and shut the engine off. This was very dangerous because cars were flying by beeping there horn at me. Ivsat there for 15 minutes wondering what to do. I decided to try and start the truck the problem was gone and I continued on my way. I called Nissan service dept. And said if happens again bring it in. On December 6th the loss of power warning light reoccurred. I brought it to the service dept immediately. The service dept. Reprogrammed engine control module. The truck problem seemed to be remedied. While on vacation in Florida in January 2017 I had loss of power twice but no warning light. On March 31, 2017, I drove truck to doctor's appt and after appt dtarted truck pulled out into traffic and truck engine power failed completely. I got truck to Nissan service dept. And has been there since. Nissan does not know what problem is and does not know how to repair truck. I am a 100 percent disabled veteran and am not able to walk very far. If this happens in the middle of nowhere I will be in trouble. I consider this truck a lemon and Nissan should man up and give me a new truck.

Intermittently looses power, total loss of acceleration. Definitely a safety hazard not knowing when it's coming. I'm very familiar with turbo lag, this is not it. Usually happens around 1/4 throttle, squeeling accessory drive belt, exhaust odor in the truck, makes you nauseous, afraid to let my kids ride in it! severe clunking in driveline, rattle in turbocharger, check engine for waste gate, leaking window seals, drips on window switch surges forward when coming to a stop, they say it's shifting into first, it will shove you into an intersection! radio has loud popping, they have attempted fixes many times to no avail. Nissan response "its normal"

The truck is leaking diesel fumes into the passenger compartment. The smell is more noticeable during a regen. The odor and fumes can become very intoxicating if stopped in traffic to the point you would need to roll the windows down or exit the vehicle for a break.

- Hammond, LA, USA

Diesel smell coming into the cab when regen is taking place its so strong and the fumes are so bad I have to get out of the truck its my opinion its carbon monoxide poisoning it is giving me respiratory trouble for my self this must become a recall before someone passes out from the fuel smell the dealer is still waiting for a engineer sins there is no fix and the dealer has never had to do a repair like this they said we don't know what to do and never had a new truck like this so I am stuck driving it and don't know when I will get a call back it happens when moving or parked and it worse driving

Vehicle lost power on highway and would not exceed 40mph with full acceleration, was able to limp vehicle to dealership for repairs. Was told dpf regen triggered engine fail-safe causing loss of power. No warning lights were visible during incident. Dealer does not know cause of issue but was able to reset vehicle. This issue occurred again several days later and has not been resolved and has no clear fix.

Cummins 5.0 liter engine missing out at 1700 rpms, you can rev the diesel engine to 1700 rpms and then all of sudden the unit starts missing out. But yet a cummins engineer stated that some of them do it, and some don't. well being a cummins tech my self I knew this was not true. Nissan refuses to send the truck to an actual cummins dealer to have it properly checked out. So U took it to cross point cummins dealership here in Indiana their diagnosis the egr flap is sticking on the casting and causing lose of power, with excessive regeneration due unit only has 800 miles on it. I have video of the issues!
