Gas Recirculation Valve (egr Valve) Problems of Nissan Titan

Received a recall for my vehicle. Recall was pd128. Took vehicle to dealer to have recall serviced on vehicle which was for a pm sensor and reprogram the emissions control module. After recall, def system error code and reduce speed to 5mph showed up on truck. Went back to dealer to explain issue after the recall. They ran codes and thought it could be the dpf filter or egr without thinking the recall could be to blame. Went to another mechanic and did a def system check and found no issue with system but a miscommunication with the nox sensor. Had nox sensor replaced and a week later had same def system error come on but was more intermittent and would clear on its own. Checked codes and found said miscommunication with the same nox sensor that was replaced. Went back to the original dealer to explain the issue and believe it was due to the recall reprogram. They did a diagnostic and spoke with their own techs and said their campaign recall repair revealed a concern that was present before but did not have detection sensor or the logic to determine the issue and recommends doc/dof to to replaced. Contacted Nissan about the issue and if replacement would be covered due to it being tied to the recall and was told no that it is just a coincidence even though their campaign revealed there was an issue with the recall.

The contact owns a 2017 Nissan Titan. The contact stated that the turbo stand, the liftgate latch and bolt had failed and were previously repaired. Additionally, the contact stated that while driving at an undisclosed speed, the check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the diesel exhaust fluid (def) system and the egr cooler was leaking. The dealer determined that the def tank and the egr cooler needed to be replaced. The vehicle was not repaired and remained at the dealer for over 6 months. The manufacturer was notified of the failure and offered to partially cover the cost of the repair. The failure mileage was approximately 109,000.

While towing a 30 foot 5th wheel trailer up a steep grade on i90 in washington state, the truck's engine abruptly slowed, and subsequent dashboard warning lights appeared. We were forced in to attempting a change of lanes to reach the shoulder. This was extremely difficult and traumatic, due to the steep road grade, abrupt slowing of our vehicle, fast moving upcoming traffic and the number of semi-trucks traveling in the right lanes. Because the speed limit in this area is 70 mph, most vehicles traveling at 80+ mph. But at the time when the truck started to fail, we were traveling at approximately 62 mph. This was an obvious and dangerous hazard to not only myself, but my family and other vehicles in the immediate area of traffic. Without warning or prior indication, our vehicle abruptly slowed down, which caused a great deal of vehicles following ours to quickly change lanes in order to avoid a collision with not only our vehicle/trailer, but other vehicles traveling and maneuvering around ours and other traffic. Once we were able to turn around and "limp" home(which in itself was extremely risky). I brought the truck for diagnostic testing at advantage Nissan or bremerton, wa. Upon testing, the fault was shown as an egr coolant or coolant reservoir fault(s). In researching, it is obvious this is a known historical safety issue or problem with Nissan's 2016-2019 cummins 5. 0 diesel engine equipped vehicles.

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.

The crank broke while driving on a 70 mph freeway and I almost got hit as I pulled over. The truck was under warranty, so the engine got replaced by Nissan. I suspect the leaking egr cooler as the cause. Water doesn’t compress when ingested into the engine. There was no warning as to this failure. Was completely unexpected. This was a couple years ago, so I doubt the parts would be available for inspection.

I was driving my truck a long distance yesterday and was on the interstate when this incident occurred, approximately 2 hours after killing the engine to get fuel. The check engine light came on, I was driving 70 mph at the time. Shortly after, a warning came up on my display stating "engine power degraded". I was on a mountain pass in the middle of nowhere and noticed the throttle was very slow, I couldnt speed up and that was very scary since I was on the interstate. I had to coast to the nearest dealer in aubun wa which was about 25 min away. As soon as I pulled off the interstate to slow down, the error cleared and I regained throttle and power. When I got there to the dealer service dept they said they had no diesel mechanics to look at my truck until 2 weeks and that I should leave it. They also told me they had no loaners, basically telling me to get a cab home. I live in tacoma, over an hour away from auburn. My truck had my dog and all my belongings inside since I just came home from a road trip, cabs were really not an option. I begged them to please just hook up diagnostics and tell me if I can make it home. They said it only showed "low voltage". They cranked my truck and I drove home. Currently it is stuck in the driveway and will not start. It will have to be towed to Nissan in tacoma whenever they can actually find a diesel mechanic. Important to note this occurred after the car wreck I was in that was likely related to throttle not kicking in. Either way, I have no vehicle and Nissan seems to think this is not their problem even though it is under warranty. It has become a safety nightmare and I am afraid to even drive this truck even if it was working.

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.

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!.

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!.
