My diesel Titan has a dangerous excelleration problem. I hit the pedal to change lanes when in traffic or when trying to merge onto a street there is a huge delay before it kicks in. I communicated through forums and online to see I am not the only complaint. The answer from Nissan is it is by design" how is this a safe design"

"dead pedal" sometimes the truck does not accelerate when pressing gas pedal. There are times when the truck is responsive and time where there is a few second delay in response. Very dangerous when pulling out into traffic or turning across traffic. The pedal response is different every time you press it. RPM jump. At times when slowing down or at a stop the RPM's will jump up for no reason causing the truck to lung forward.

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?

As best as I can describe it, the truck does not get fuel when pressing the accelerator preventing it from moving forward. You can push the pedal all the way to the floor before anything starts to move, and sometimes not at all. We've had to pump the pedal and press it all the way down on several occasions causing us to almost get hit when pulling into traffic. We've spoken with Nissan service advisors and sales associates about the issue repeatedly only to be told that Nissan does not have a fix for the problem in the works even though they've received complaints about the exact same issues from other owners. This is a continuous ongoing problem, occurring every time it is driven.

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"

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.

On November 2, 2016, I was driving my 2016 Nissan Titan xd (diesel) on a city street when the engine suddenly shut down on me. I was able to get the vehicle safely to the side of the road (loss of power steering and brakes). I had the vehicle towed to the dealership, where it remains to this day (November 30). The dealership, along with assistance from Nissan, has not been able to repair or restart the vehicle to date. My understanding is the fuel has been tested and was determined to be clean diesel and problem free. The fuel rails were first replaced, with negative results. The high pressure fuel pump was then replaced, again with negative results. My last contact with the dealership was one week ago, and I was told the Nissan engineer's felt the fuel system/engine was not getting "primed" and they were going to look into that system. Still, , the vehicle remains at the dealership and they have not been able to start then vehicle or correct the problem. I am concerned other owners of this type of vehicle may or may already have experienced similar issues. This is obviously a safety issue that needs to be checked because it could result in a severe accident resulting in injury, loss of life and/or property damage.
