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.

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"

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).

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.

As I start to accelerate from being stationary, the 1st, 2nd and 3rd shifts bump hard. And as I'm coming to a stop after feeling that I can feel it down shift rough as like it's downshiftig to soon. Something needs to be checked on it. It's recurring and hasn't stopped since I bought the truck two days ago.

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.

Driving from Nevada to los angeles ca on highway 395. Three times while at speed my vehicle turned off for three to five seconds. I lost power steering, rear tires felt like they locked up. Car would then power back on and I would regain power steering and continue down the road. This occurred three times in 40 miles today. This vehicle has been back to the dealer I bought it from where they could find nothing wrong with it.

While driving from pensacola fl to my home on I-110, a car pulled out in front of me causing me to tap on the brakes, to slow down., when I tried to reaccelerate there was no response for around 5 seconds, almost causing me to be rear ended.

- Gulf Breeze, FL, USA

From stopped position: 1-3 second or greater delay (lag) in acceleration to movement of vehicle. While driving: 1-3 second or greater delay (lag) in acceleration to response of vehicle. Jerking motion between gears. No predictability of applying acceleration while moving or stopped creating safety concerns. Nissan is aware and is stating this is normal. Occurs while driving all speeds including attempting to cross intersections or pass on highway.

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?

- Prior Lake, MN, USA

Acceleration delay from stop or yield. Step on the accelerator pedal too fast and it just sits there until it decides to move. Dealer states it is normal for torque control. Dangerous when pulling into traffic at any speed.

- Spring City, PA, USA

The computer is apparently set so an abrupt acceleration such as trying to get into traffic will cause a momentary stall resulting in a dangerous situation.

- Billings, OK, USA

Driveshaft broke while driving on highway at 70 mph. Vehicle started to vibrate violently and slowed down quickly to 20 mph. Had to pull over the vehicle on the side of the highway to be towed. Vehicle had 16000 mile when this happened. I felt very unsafe and was lucky that this did not caused an accident.

Titan xd with cummins diesel and aisin transmission has 4-10 seconds of unresponsiveness when attempting to accelerate from a coast from 10-25mph. This happened to me with my family in the truck when attempting to merge into traffic leaving us facing oncoming traffic without the ability to move out of the way. The pedal was pressed to the floor and there was no responsiveness from the truck. No downshift, no engine revving, no acceleration. It was like I had not even pressed the pedal. This has been reported to Nissan and my dealership without resolution. Also their is a delay when attempting to pass from 40-50mph. This delay last 3-6 seconds and then the truck will downshift to the wrong gear, not accelerating for an additional 3-5 seconds, and then will finally downshift again to the correct gear and begin accelerating for a total delay from acceleration command to actual acceleration occurring of 6-11 seconds. When attempting to merge (assuming on coming traffic traveling at 55mph) a 4-10 second delay means that the driver (me) mis-judges the space available to merger by 322-806 ft. Which is what happened to me because I expected the my truck to accelerate when I told it to and nearly caused me to have a driver side collision with head on traffic. When attempting to pass (assuming both vehicles are doing 55mph) a 6-11 second delay means the driver (me) mis-judges the space available to pass by 968 - 1775 ft <-- that is greater than 1/4 mile of ground closed between me and on coming traffic before the truck even begins to accelerate. This has also lead to a narrowly avoided head on collision on a rural highway. Both of these conditions are easily repeatable and are not intermittent phenomenon.

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.
