2018 Nissan Armada: won't start

Filed Oct 16, 2025 · Fuel system · TX

Well wife was driving car on her way to work and it shut off in the middle of traffic. Was no sure what was wrong until I brought it home and started reading the codes. It gave me P0087 P0090 low fuel pressure regulater circuit open and P119C. So I changed out the sensor the in tank fuel pump, high pressure fuel pump and sensor on the evap can. Car still will not start. So I bought a wiring diagram to see were everything was routed and found out the have a built in fuel relay so I bought a new PCM that didn't work so then I found out it there was a fuel pump controller module so change that and still not cranking. Fuel pump flows fuel for a second then shuts off. Now I am not sure what to do now. Truck has been down for 3 weeks now. And been have to renting a car since then.

My 2018 Nissan Armada (VIN: [XXX] ) has been experiencing no-start issues consistently for the past three years. Two years ago, I purchased a new battery from a Nissan dealership after being told the existing one had failed. Despite that replacement, the problem persisted and continues to this day. The vehicle intermittently fails to start, often producing only a click sound even though the battery, alternator, and starter test as functional. I now have to jump my car at least five times a week just to drive it. Through research and online forums, I’ve found that many other owners of this model report identical issues, which appear linked to the brake lamp switch or Body Control Module (BCM). While Nissan has issued Technical Service Bulletins for these concerns, no formal recall has been offered. This ongoing electrical malfunction is a serious reliability and safety issue—especially if the vehicle fails to start during a critical situation—and I urge the federal safety agency to investigate.

The start hesitation started about 2 years ago, but my Armada never did not start. Then about a year so ago the Armada would not start, and it would not start in Dover, DE, and I had to call Geico to get a jump. I had a brand-new battery installed thinking that was the issue months prior, but my Armada would not start again. I took it to the dealership, and they charged me diagnostic but could not find any issues. After numerous times of my Armada not starting, I bought portable jumper whenever this happens. Just last week I was in Milford and went to start my Armada and it would not start. It clicked and then no power anywhere... the same as other times. I called Geico roadside and while waiting about 10 minutes, my Armada started, and I drove it straight home. I tried to start it the next day, and it started with a slight hesitation, but it started. So now when I go places, I will not turn my Armada off for fear it will not start again.

I TAKE MY VEHICLE TO THE SAME DEALER FOR ALL SERVICES AND OVER THE PAST SEVERAL YEARS, I'VE HAD "BATTERY ISSUES" THAT TURN OUT TO BE CONTROL MODULE ISSUES THAT REQUIRE NEW WIRING FOR THE VEHICLE TO RUN AT ALL, BATTERY COMPLETELY DRAINS AFTER SEVERAL SMALL TRIPS AROUND TOWN. I HAVE FULLY REPLACED THE BATTERY, DONE A WARRANTY ON IT AFTER THAN AND I'M STILL CONSTANTLY STRANDED. NISSAN DOESN'T WANT TO COVER ANY OF THE LABOR ($645.00) THAT IT REQUIRES TO RUN AT ALL. NO PARTS ARE NEEDED, IT'S JUST LABOR TO RECONFIGURE THE WAY THE ALTERNATOR WORKS BUT THEY'RE TELLING ME IT'S MY PROBLEM TO FIX BUT IT'S NOT A WORN OUT PART, IT'S LITERALLY THE ELECTRICAL. What component or system failed or malfunctioned, and is it available for inspection upon request? BATTERY & SMART ALTERNATOR How was your safety or the safety of others put at risk? VEHICLE WILL NOT START, BATTERY COMPLETELY DRAINS AFTER SEVERAL SMALL TRIPS AROUND TOWN. Has the problem been reproduced or confirmed by a dealer or independent service center? YES, THEY'RE FULLY AWARE OF THE PROBLEM THAT THESE ARMADAS ARE HAVING, RECALLS CURRENTLY ON 2017 & 2019 MODELS BUT THEY'RE NOT RECALLING MY YEAR, 2018! Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? YES, DEALER SERVICE CENTER SEVERAL TIMES. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO. FIRST STARTED IN 2019. I'VE GONE THROUGH SEVERAL BATTERIES, ROADSIDE ASSISTANCE AND PERSONAL JUMPS DUE TO THE FAULTY BATTERY LEAVING ME STRANDED SEVERAL TIMES OVER.

Our Armada started having trouble starting a few months ago. A new battery from Nissan was installed 7 months ago. We have been stranded twice do the car failing to start. Portable jump starters of any size have not been able to assist the car in starting. Only jumper cables to another vehicle have allowed us to get the car to start. Some starts are fine, some sluggish but start and some fail to start. It appears to be totally random. My most recent incident went like this. Car had a good strong start. We drove it for 30 minutes and parked. We were out of the car for 10 minutes and car would not start upon our return. We had to wait for someone to come give us a jump start. We have taken the car to two different Nissan service centers. The first told us there was evidence of a problem but nothing they could identify and to just keep driving it. Problems persisted. We then took it to a second Nissan service center. They told us nothing was wrong but possibly a loose battery connection. While at the service center, another Armada was there for the same symptoms. Are problems continue to persist. We spoke with some friends that own a 2019 Armada across the country and it has the same problem. They reported their Nissan dealer was very ellusive as to what is going on. I feel like Nissan knows there is a problem but doesn't want to do anything about it because of the cost to their business. If these failures occur during extreme cold or hot weather, or in isolated places, it could cause bodily harm or even death. I had a problem with Mazda similar to this previously where they knew there was a problem but refused to do anything about it. My friend was a service manager with Mazda at the time and showed me an internal memo on the subject but said I couldn't have a copy. He was afraid for his job. I'll ask our friends to enter a complaint also so you hear it from more than one person.

Fall 2020, I began having intermittent, no start issues with my 2018 Nissan Armada. It was sporadic. When the start button is pressed, it would do nothing, turnover slowly, or not turnover at all but make clicking noises. It always eventually started, sometimes within minutes, other times up to a couple hours. December 2020 - I thought the battery might be bad, so I had it replaced at Walmart 12/7/20. March 2021 - the problem continued so I researched online and found that this is a common problem for 2018 Armada’s. Posts on ClubArmad.com stated the problem could be a bad brake switch. I purchased a new switch from Pat Peck Nissan Mobile and replaced it myself. Unfortunately, the issue continued intermittently. December 2021 – I took the vehicle to Matt Bowers Nissan Eastern Shore. Diagnostic testing was done that found a low voltage code. The battery was reconditioned for $145. They also performed an ECM software update that was covered under warranty. They felt like this should fix the issue. This did not correct the problem and it became more frequent. February 2022 – I took the vehicle back to Matt Bowers Nissan Eastern Shore. Their conclusion was now the battery was causing the issue. They stated it was discharged and recommended a replacement even though the battery was only 15 months old. They installed a new battery for $244.98. This did not correct the problem. May 2022 - I took the vehicle back to Matt Bowers Nissan Eastern Shore. Their conclusion this time was it was a bad stop lamp switch, the same part that I replaced December 2020. They replaced the switch which was covered under warranty. This did not correct the problem. January 2023 - I took the vehicle back to Matt Bowers Nissan Eastern Shore. They could not replicate the issue but stated they believe it is the starter and this time recommended replacing the starter for $1124.84 plus tax. This problem has been ongoing for two and a half years with no resolution.

Component or system unknown other than personal research. Suspect break sensor or possibly called stop lamp. Again, not positive. My Armada randomly will not start, leaving me stranded many times (with children). When I push the start button, sometimes the car shakes while making a horrible sound and trying to start but never starts. It has to be jumped off before it will start. Sometimes, it just clicks and does nothing. We took to our local Midas, who found no codes triggered, battery, alternator, starter etc all good. We drove another week and it happened again so this time we took to the Nissan dealership. Again, they checked everything, found nothing. Upon researching myself, I'm finding many people having this same issue yet Nissan team has no clue what to fix. I'm stuck driving a car that leaves me randomly stranded or doesn't start at all for me to even leave my house. I tried looking up the part myself and adding a new one (desperate to find the issue) but I'm not car savvy and can not locate the "easy" piece near my break pedal. I'm getting desperate and should not have a car with less than 70,000 miles leaving me stranded. No warning lights appear.

Several times the engine will not crank and will not start. Can take up to 10 minutes sometimes before vehicle will start, leaving driver stranded. Twice now the bci malfunction (backup collision intervention) error came up on the dash along with other lights immediatly after engine startup. First time at 23,027 miles, and now recently at 32,081 miles. The first time, dealership said they "could not replicate the problem." this recent time, the dealership said there was a service bulletin to replace a stop lamp switch (ntb20-065). We'll see if the problem is actually fixed. This should really be a recall considering the shear number of similar complaints about this issue. Plus the brake lamps may not work consistently, elevating the risk of a collision if other drivers aren't aware the vehicle is slowing down.
