Engine Exhaust System problems of the 2016 Nissan Titan

Engine loses power, slows down to a creeping 5-10 mph during peak hour traffic or turns-off completely. Instrument panel reads exhaust filter overload/reduced speed. Afterward, vehicle will not start at times or will start but resumes 5-10 mph speed of travel. Had manual reset performed; only 44 miles later to have same engine trouble beset the vehicle again.

There are diesel exhaust fumes coming into the cab while the vehicle is running. There is no difference whether the air conditioning is on recycled, fresh, or if it is off completely. The smell is overwhelming and does not go away even with the window being rolled down. The fumes also come into the cab whether the vehicle is stationary or in motion. The fumes do not increase nor decrease depending on the speed you are driving. The fumes are constantly there, at the same smell.

Tl-the contact owns a 2016 Nissan Titan. The contact stated that there is an exhaust leak underneath the cab. The contact took the vehicle to the dealer allen samuels Dodge Chrysler Jeep ram 201 w loop 340, waco, TX 76712 (254) 848-6200 stated that since the vehicle was still under warranty from the Nissan dealer. They stated that the exhaust pipe was supposed to leak to allow condensation to leak and no repairs were done. The contact was concerned the carbon dioxide levels might cause the contact to pass out causing an accident. The manufacturer has not been contacted. The failure mileage was 38,000. Tf.

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.

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.
