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.

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.

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!
