Bought truck new in 6/2018. Truck is new 2017 leftover Nissan Titan diesel xd with 16,000 miles to date. When truck goes into regen to clean diesel particulate heavy diesel exhaust fumes fill the cabin so bad you have to roll the windows down. It causes my stomach to become upset and dizzy tired feeling and later a very bad headache. Have had coworkers experience the same issue while in the vehicle.has been replicated at the dealer and service tech and service manager are out of ideas on how to fix this but confirm the issue exist. Dealer service manager has read about this but never has heard of a fix through Nissan. Nissan is sending in and engineer to look at the issue but comment made from service manager is he has heard about the situation through Nissan network but never has heard of a fix for it. Truck is still in warranty but not worth continuing to be sick or possibly pass out from it. Please be very aware of this issue and report any exhaust diesel smell to your dealer and elevate it. This is an extremely dangerous health and safety hazard. You should not smell any exhaust or diesel fumes in a vehicle. Hoping this site takes note of the many other folks on forums mentioning it and elevate it to Nissan. Hoping Nissan fixes or gives me my money back as the truck makes me feel sick.

As I was driving on the road at red traffic light, when the light turned green, I started to move, the engine started to make loud noise and the engine shut off. This happened when the vehicle was at 56K miles. Later on, found out at dealer that the crank shaft was broken. The engine got replaced under warranty. It is not a guarantee that this does not happen again. There are lots of other same model truck had this happened. 2017 Titan xd 5.0 cummins diesel

Engine fan clutch makes excessive engine noise. Sounds like a jet engine. Dealer claims it is as designed, however, it is excessively loud, and causes extreme drope in overall fuel economy. This is a known failure that the selling dealer refuses to fix.

When making a left turn across a 2 lane highway, after slowing down to make the turn, the vehicle did not respond to depressing the accelerator pedal, nearly causing an accident with oncoming traffic, which had to slow down abruptly to avoid collision. There was ample space at the beginning of the turn maneuver to comply with traffic law. It took approximately 3 seconds for the engine to respond to depressing the accelerator pedal, and the application of power was sluggish at best. During that time, the vehicle rolled slowly across the lanes of oncoming traffic. Depressing the pedal to the floor did not cause a response by the engine. The vehicle had coasted nearly all the way across the two lanes of oncoming traffic before there was sufficient power to accelerate.

Sometimes the traction control light will come on in the middle of me driving. Then it reduces my Titan to 10mph. It has happened twice while the vehicle was in operation and I was going less than 30mph both times. The traction light will also come on when I drive somewhere and let my car sit idle. Usually when that happens all the light appear. I'll turn it off and all the lights will disappear except for the engine light. The first time this ever happened was when we were sitting idle in a parking lot and at first it wouldn't even go anywhere.

To whom it may concern I was driving with slightly less than 1/4 tank of gas and stopped to park on a hill with vehicle on idle. While in idle on the hill the vehicle stalled out. I tried to restart but the engine just cranked with no start and a low pressure fuel system service light came on. I tried to push it down the hill on flat ground and tried to start again with just cranking no start. I then had to push the vehicle with the help of my neighbors into a guest stall and call for a tow. The vehicle was towed to tony Nissan to be looked at where the mechanic said that there were no issues and he reviewed all the fuel system and no issues were found. He informed me he let the vehicle crank over until the pump was able to pick up fuel and purge the line of air and the car started. The service advisor informed me of the fuel tank being longitudinally placed in the truck with fuel pump in the center which stopped to idle on a hill may have caused the pump to go dry and pump air. I informed him that this could be an issue if I was driving up or down a hill with my family and then stop and idle whereby the truck stalls out on a hill of such magnitude like in san francisco or wilhemina rise in honolulu, hi. Hopefully this is reviewed by the engineers at Nissan motor which this email is also being forwarded to NHTSA. Invoice number, I believe, from tony Nissan is 653922.

On Feb 16 2018 I was driving my 2017 Nissan Titan truck with 5000 miles on the odometer along a rural two lane road in Missouri with three other passengers riding with me. We heard a noise from the engine compartment and suddenly the power steering of the vehicle ceased to operate and the truck drifted across the double yellow lines of the highway. Luckily no cars were coming in the opposite direction and I steered hard to the right and slowed the vehicle down rapidly. I drove a short distance to a gravel parking lot of a church and we examined the vehicle and could see the serpentine belt was no longer in place. The truck was towed to a Nissan dealership 55 miles away and we awaited their report. Several days later I was informed that the belt tensioner bracket had broken in half and Nissan was going to order parts as they were not in stock at the dealer. Remember this is a new 2017 truck with only 5000 miles on it. The serpentine belt runs all aspects of the vehicle and without it engaged the vehicle becomes undriveable. The vehicle is completely stock with no modifications of any kind. The Nissan dealership advised me that I was the only person in the U.S. with this malfunction to date. This problem could potentially kill.

When the diesel engine goes into dpf regeneration mode, the cab of the vehicle fills with unpleasant fumes that smell like evaporated diesel fuel or other noxious substance that is irritating to mucous membranes and may cause health issues. The problem is worse when the vehicle is at low speed or in stop-and-go traffic when exhaust fumes are able to collect around the vehicle. The most recent instance occurred in a drive-thru line at a fast food restaurant, and was so pungent that I was forced to abandon the line, park the vehicle, and evacuate myself to fresh air.

The truck I have purchased on Nov 24th, 2017 has the cummings diesel engine. The truck is known not to start in weather below 12 degrees F. Nissan techs tell me now (after the sale) that this engine needs an anti fuel gell addidative in order for the vehicle to start in cold weather. I feel I have been robbed of the $50,645 I spent on a new vehicle. This is not at all an acceptable answer to me. I have a 2005 Chevrolet K3500 with a Chevrolet duramax diesel that in 12 3/4 years has not had one drop of anti gel fluid placed in it, & has never failed to start not one single time with 235,000 miles on it!!! I find this unacceptable, & demand some sort of action be taken. I bought a vehicle in the good faith it was going to last. Instead I have bought something I hate now; never knowing weather or not it will start. Vehicle has failed to start on multiple days. About 6 days total so far since christmas of 2017. Filled a case #: 29386597... Nissan closed it after saying there was nothing they could do! also filling a complaint with the Indiana state attorney general, & BBB!

Very soon after I purchased the Titan truck, randomly, while the car sits idle or while driving the truck anywhere (I.e. on city streets, on the highway, in my neighborhood) the truck produces a strong scent of diesel mixture/exhaust fumes in the cabin of the truck. The fumes are so strong it makes me dizzy. The diesel fumes/exhaust smell in the cabin when the def cycle is on as well. I've taken it to a Nissan dealership at least four times to no avail at repairing it. I bought this truck as a new car.
