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.

Vehicle won't properly accelerate especially when making turns. Vehicle is ventilating diesel exhaust gases into cabin when heating or cooling system is on.

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.

While merging into traffic on hwy 98 there was a significant lag in acceleration, almost causing me to be rear ended. As I turned to merge and pressed the accelerator there was no response for 5-6 seconds, I never experienced this lag in my 2011 Nissan Titan.

I have had my 2016 Nissan Titan xd platinum reserve diesel for 1 month and have driven it about 450 miles. On 3 separate occasions when accelerating from a stop sign I have gotten a dead pedal. While accelerating reasonably (not mashing the accelerator) from a stop sign to cross an intersection the truck would roll forward about 6-8 feet then nothing (no acceleration, no RPM rev, just dead) for 4-6 seconds. Then with the pedal still about 1/2 way down the truck would respond and take off like a rocket. This is a huge safety issue as a driver should expect the vehicle to accelerate when pressing the accelerator. This caused one very narrow near miss by an oncoming vehicle as I sat dead in the water in the middle of an intersection for 5 seconds. The other 2 occasions there were thankfully no oncoming vehicles. I now have to make sure there is no other vehicle in sight to feel safe in crossing an intersection or pulling out into traffic. This issue needs to be resolved before someone is kill, if that has not already happened. The dealership has no idea what the issue is.
