Gas Recirculation Valve (egr Valve) problems of the 2016 Nissan Titan

Ever since I purchased this truck in 2017 I've had problem after problem turbo actuator has been replaced twice and and is out again and not at cost on Nissan refused to pay for recall after it was replaced . Coolant level sensor also replaced and is out yet again and have to replace reservoir also because sensor not sold seperatly egr is leaking and out as is engine low oil light on and mechanic is beliving engine has blown up not sure cause yet until engine removed at my cost and replaced . These issues have had me in heavy traffic several times putting truck in limp mode making it unsafe for others and my self twice with grand children on board also dealer found melted wires in box harness that they wanted to replace indicated trailer wiring malfunction also a fire risk for truck . Steering pump has always been sluggish since I've owned dealer refused to address it said it was working fine yet there has been issues with similar trucks . There have been several engine codes regarding coolant . Egr codes turbo codes and low oil pressure codes with good oil quantity before engine failure . I have always changed oil on this vehicle every 4000 miles fuel filters twice a year since owned have kept vehicle in best maintenance since owned . I also would like to note dealer billion automotive is a absolute nightmare to work with all warrantee work with myself and my son who owns same truck he has had similar problems with his truck as well egr turbo also turbo actuator def system replaced steering pump replaced because it fell off because of failed bolts all of these were repaired by dealer and documented as were mine.

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.

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.

Cummins 5. 0 liter engine missing out at 1700 rpms, you can rev the diesel engine to 1700 rpms and then all of sudden the unit starts missing out. But yet a cummins engineer stated that some of them do it, and some don't. Well being a cummins tech my self I knew this was not true. Nissan refuses to send the truck to an actual cummins dealer to have it properly checked out. So u took it to cross point cummins dealership here in indiana their diagnosis the egr flap is sticking on the casting and causing lose of power , with excessive regeneration due unit only has 800 miles on it. I have video of the issues!.
