Manifold/header/muffler/tail Pipe Problems of Nissan Armada

Engine making a ticking noise coming from the right side. Believe it's the manifold being cracked.

In July 2017 and at 90k miles , my 2010 Nissan Armada began leaking exhaust fumes into the passenger cabin and the fuel economy dropped significantly. I took it to an authorized Nissan service station, which charged me $150 to diagnose a cracked catalytic converter exhaust manifold on both sides. The repair estimate was about $4,000 to replace the manifolds at the dealership. The manufacturer's warranty expired at 80k miles and I was told that this is a known problem with Armada and titan models. I shopped around for estimates and had the manifolds replaced by an independent mechanic with aftermarket parts for a total cost of $2,100 with a 2-year/24k miles warranty. In 2020 and at 125k miles (3 years/30k miles later), the same issue occurred and the shop would not extend the warranty. The Nissan dealership service department estimates the repair at $5,000, and the independent shop estimates $1,900. All of the mechanics (including the Nissan dealership) have advised me that they don't think the car is worth the investment at 130k miles considering the trade value is around $5k. I can't afford this repair twice in 3 years, and I'm driving my family around breathing in CO fumes that could harm or kill us. I primarily use the vehicle for day-to-day suburban driving with occasional camping trips - no hard or off-road use. Nissan should address this issue and reimburse the cost of repairs as this is a potentially fatal issue for drivers. I am now faced with a decision to invest almost half the value of my vehicle in a repair that may fail again, or to buy a new car I can't currently afford in the middle of a pandemic. Please hold the manufacturer accountable to its us customers.

The contact owns a 2005 Nissan Armada. The contact stated that the muffler had been replaced 3 times due to it cracking around the header. The contact stated that the muffler damaged wiring harness and the computer system, which caused the vehicle to stall. Hummel's Nissan (4770 merle hay rd, des moines, IA 50322) was made aware of the failure. The muffler was replaced twice by the dealer however, the muffler failure recurred. The muffler was replaced a third time by an independent mechanic. The manufacturer was not made aware of the failure. The failure mileage was 68,000.

The vehicle will start having erratic rpms, hesitation to accelerate, engine rpms will not go above 2000-2500 or below 1000-300 without severe hesitation, then sometimes it will just completely shut down everything no matter if stopped at a light or driving highway speeds. Total loss of vehicle control happens. . . No brakes, power steering, no acceleration. Every light turns on on dash and if your driving at the time you better hope that you can quickly throw it in neutral, crank the engine at least 2-4 times before it'll start up, then kick it back in drive to gain control of the vehicle again so you can pull over somewhere safe before you get into a serious wreck. Taking it to Nissan was pointless since after you get the Armada restarted, it doesn't retain any codes that the dealership can use to diagnose the problem nor can the mechanic replicate the issue on test drives. At which point I look like I'm the crazy one, then they send me off on my way with no answers. The only other problem that the Armada had long before this problem, during it, and currently is a cracked exhaust manifold which, too, is apparently a very common issue that plagues other Armadas which Nissan refused to acknowledge as a very common problem and issue a recall. This issue is hard to support with pics or documents since it almost always occurs while the vehicle is in motion so you're too occupied trying not to kill yourself or others on the road and when you do go to Nissan there no codes to pull since I guess the vehicle erases it after the complete loss of power. Feels like I'm chasing my tail. . .

Both of the exhaust manifolds and catalytic converters in our 2011 Nissan Armada have cracked. As a result, exhaust fumes were leaking into the passenger compartment creating a potentially deadly concentration of c02 fumes in the passenger compartment. This is a known design/engineering defect on all v8 Nissan Armada and Nissan titan engines for at least 10 years. Nissan will only cover the federally mandated 8 year/80,000 emissions warranty. C02 inhalation causes hundreds of deaths per year in the us. This is an obvious safety issue that is known to the manufacturer and well documented in thousands of cases. As such it should be covered in full by the manufacturer. This repair cost us $2439. 36. Nissan should reimburse us in full for the repairs.

Both passenger and driver side exhaust manifold cracked at the same time.

During a family camping trip, towing a camper, at ~54,000 miles the exhaust broke off the vehicle at the mounting flange just behind the muffler. This caused exhaust to heat the floorboards just at the 3rd row seats, melting the plastic cover to the mounting bolts of the seat to the floor, and melting the carpet in the same area, and filling the cab with melting plastic fumes. It also melted the rear air-ride suspension air line, causing the system to be in-operable while towing and off balance loading while driving.

Tl the contact owns a 2011 Nissan Armada. After starting the vehicle, a ticking noise was heard coming from the engine compartment. Also, the vehicle would not accelerate properly and stalled on multiple occasions. The vehicle was taken to Nissan of lake norman (18615 statesville rd, cornelius, nc) to be diagnosed, but the cause of the failure could not be determined. The vehicle was then taken to an independent mechanic who diagnosed that the exhaust manifold was cracked. The manifold was replaced, but the failure recurred. The manufacturer was not notified of the failure. The failure mileage was 140,000. The VIN was invalid.

"takata recall" so I have a 2006 Nissan Armada that just recently had the exhaust manifold change out for crack manifold and it hasnt been a year yet and already have another crack manifold. Nissan really need fix this issue because no one has that kinda of money to be buying new exhaust manifold every year for emission.

The contact owns a 2006 Nissan Armada. The contact noticed an abnormal exhaust odor in the vehicle. Upon inspection, the contact discovered that the leak stemmed from the exhaust manifold into the passenger side cabin. The vehicle was taken to lamb Nissan and the leak was confirmed. The dealer stated that the exhaust manifold needed to be replaced. The manufacturer was notfied of the failure and offered no assistance. The failure mileage was approximately 80,000.

The contact owns a 2009 Nissan Armada. Upon starting the vehicle, a ticking sound was heard coming from the engine. The vehicle was taken to Nissan of victoria (6003 n navarro st, victoria, TX 77904 (361) 578-5000) where it was diagnosed with a cracked manifold that needed replacement. The vehicle was not repaired due to an expired warranty. The manufacturer was not made aware of the failure. The VIN was unknown. The failure mileage was approximately 80,000.

I purchased this vehicle and within the first 3 days of having it noticed what sounded like an exhaust leak. I was assured it would be taken care of not to worry. Five months later it is still not fixed and the problem is that the exhaust manifold is cracked. Not just one side but both sides. I am sure that the problem existed when I purchased the vehicle. How is this possible? and why isnt there a recall seeing as there have been so many complaints of this issue. Also, on several occassions I have been locked out of the rear hatch of the vehicle unable to open it even though the vehicle is unlocked. I even crawled from the front to the back to try the emergency latch and nothing would allow it to open. I purchased this vehicle with 138k miles and seemed to be in excellent condition. . . I guess the old saying "looks can be deceiving".

We purchased our car used with 53,000 miles on it. Upon reaching 60,000 miles we heard some knocking and periodically smelled exhaust in the cabin while driving. We took it to the dealership for diagnosis and was told that both exhaust manifolds were cracked and needed replaced. We were also told that Nissan did extend the warranty for this issue on some 2006 Armadas to 80,000 miles, however the time period had been too long for our car to be covered. I contact Nissan consumer affairs directly and was told that there was nothing that they could help us with, and were not even willing to tell me if this is a known issue with this year and model of vehicle. I have seen several complaints from other consumers with the same year and model online, and it appears there have not been enough issues yet for Nissan to take any really responsibility.

This is a concern. As a senior maintenance manger for the us army, recently retired, and a vast knowledge of mechanical, and safety training, I came across an issue that could be potentially fatal. The valve or rocker covers on the Armada slant down, away and back from the engine. The bottom back corner of the valve cover sits perfectly over the exhaust manifold and catalytic converter (drivers side). If the seal is broken and the oil seeps out it will drain to the lowest point and drip down onto the top of the heat shield for the catalytic converter and pool under the converter. When the vehicle is driven that oil gets hot and burns and can possibly catch fire. Depending on how much oil has dripped onto the heat shield and how long the vehicle is driven would determine the heat needed to generate a fire. Depending on the size of the fire it is possible it could burn the fuel lines that run in the same area.

The contact owns a 2008 Nissan Armada. The contact heard a loud noise when the vehicle was started. One mechanic stated that the exhaust manifold needed to be replaced. A second mechanic also inspected and diagnosed the vehicle. The vehicle was to be taken to a dealer for further diagnostic testing. The manufacturer was notified of the failure. The approximate failure mileage was 60,000.

Cracked exhaust manifold identified. Dealer took 2 months after requesting a trip to the dealership (200 miles rt) to deny any responsibility because vehicle is over 8 years new. Been cracked for years and they knew its age before requesting an inspection. We were told by dealership to be wary of exhaust leaking into the cabin.

My vehicle was making a noise like it had a hole in the exhaust. Come to find out, both of the exhaust manifolds are cracked. 3000 past the 80000 mile warranty and Nissan will not cover it. Needless to say, I sure wish there could be an extension to this warranty as there was with another manufacturer that extended it to 100000 miles. Something needs to be done. This is a failure to protect the american consumer.

10/28/09 right manifold and catalytic converter cracked between 3rd and 4th runners at 56k, 9/28/10 left side cracked at 67k. Both replace under warranty. 03/16, 135k kept complaining of exhaust in cab and being light headed. Brought to mechanic, right side is cracked again! I care for and transport our 2 year old granddaughter while our son is in the military and can't believe this isn't considered a manufacturer defect due to the safety issue. Have always had Nissan, love to get another one but not if Nissan doesn't back their product.

My problem started around 12/5/08 when my truck died unexpectedly. It restarted then later more of the same on the same voyage. Local Nissan was contacted that day and an appointment was set for 12/15/08. At that appointment it was determined that it was caused by the vehicle security function and was reset and key was reprogrammed. They had noted that the exhaust manifolds had failed and needed replacement. The mileage was 81,470, 1470 miles over the federal warranty. My mileage was arguably under the 80,000 warranty limit when the appointment was made a week prior. Two weeks later, the same symptoms occurred. This time it is added with power loss of mass proportion on and off again. Again back to Nissan were they are pointing at the manifolds. Other customers with the same exact symptoms have had the ipdm, bcm, ecm, manifolds, and the key reprogrammed and the dealerships still cant find there problem. The service department acknowledges my concern that this isn?t the part causing the intermittent issues. Nissan realized the problem with its manifolds and corrected by making them ?beefer? and adding a support brace in later production runs. I have tried to resolve the problem through Nissans consumer services, but was denied assistance (case #6392768). The internet is flooded with Nissan truck customers whose manifolds have failed in the same exact places on the part during the production run date. Nissan has even warranted this part to other customers after the expiration of the warranty but why not me? there suggesting ?starting? with the manifolds @ $2400 estimate I can?t afford, and if that doesn?t fix the problem im in the same boat as the other? throw parts you cant afford at it? crowd. I bought there flagship vehicle, expecting utmost service unlike there counterparts. Im ready to discourage anyone I cross from the Nissan product line, my lawyer has already been contacted, and if this isn't resolved swiftly being without a veh.

The contact owns a 2004 Nissan Armada. While driving 60 mph, a warning indicator illuminated on the instrument panel. The vehicle has been to the dealer approximately three times for repair. The first time it was taken to have the brakes repaired for making grinding noises. The contact stated that she was using the wrong brakes. When the accelerator pedal is depressed, the pressure goes down and the vehicle decelerates. The contact would have to bring the vehicle to the dealer in order to determine the cause of the failure. In addition, there is a clicking noise coming from the transmission. The dealer cannot locate the cause of the failures. The VIN was unknown. The failure mileage was 30,000 and current mileage was 84,000. Updated 05/08/09. The right side exhaust manifold was replaced and the engine light had illuminated. Updated 05/11/09.

Tl-the contact owns a 2004 Nissan Armada. The contact stated that while driving at unknown speeds, the vehicle was making an abnormal sound as exhaust fumes emitted into the cabin. The vehicle was taken to the dealer. The technician diagnosed that the right and left exhaust manifold were defective and needed to be replaced. The vehicle was repaired. However, the failure recurred. The vehicle was taken back to the dealer, where it was repaired under an unknown manufacturer satisfaction campaign. Six years later, the failure recurred a third time. The manufacturer was made aware of the failure and refused to provide any additional assistance. The vehicle was not repaired. The failure mileage was 70,000. Pm.

The vehicle's home-link system failed. The consumer stated that the memory seats for the driver does not work. A vibrating noise was heard from the heat shield from the exhaust manifold. Vibrating noise heard from the interior courtesy light lens. The liner on the roof passenger liner is separating. Tire pressure sensor malfunctioned.

The consumer stated that there is a problem with the radio reception. Cracks developing in the engine compartment heat shield. Headphones for the dvd system where not provided.

I am writing as a follow up to a news article out today that talks about how cracks in Ford exhaust manifolds are making vehicle owners/drivers/passengers sick through poisoning gases entering the cabin: https://www. Bloomberg. Com/graphics/2019-Ford-explorer-owners-say-suvs-making-them-sick/ this is not the only vehicle with this very serious problem. There are very serious problems with the Nissan Armada/titan exhaust manifolds cracking and emitting toxic gases, from 2004 on up. These vehicles, equipped with a 5. 4l engine, are highly susceptible to exhaust manifolds cracking and exhausting gas. This exhaust gas can easily make it's way into the vehicle passenger compartment, and cause sickness, dizziness, nausea, or possibly even death from co2 poisoning. The problem so bad on these vehicles, that aftermarket companies have for many years now started making exhaust manifolds that have reinforcements welded onto the areas of the stock manifold that regularly incur these cracks. The job is extensive, however, and many vehicle owners cannot afford these repairs. Many vehicle owners likely don't know what is making them sick.
