Manifold/header/muffler/tail Pipe problems of the 2006 Nissan Titan - part 1

The contact owns a 2006 Nissan Titan. While the vehicle was stationary, the exhaust manifold fractured. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the issue. The failure mileage was 96,000.

Tl-the contact owns a 2006 Nissan Titan. The contact stated that there was a strong fuel odor inside the vehicle. The failure was persistent. The vehicle was taken to an independent mechanic where it was diagnosed that both rear exhaust manifolds fractured and needed to replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 166,466. Ec.

Cracked exhaust manifold has been noted, and/or. Possible malfunction of catalytic converters welded to manifolds. 118,500 miles. Replacement manifolds/cats cost is very expensive and labor intensive. So-called "common problem" with Titans. Imo, this problem may possibly send co2 to passengers if not corrected, not to mention poor vehicle performance and possible severe engine damage if not corrected. Nissan should certainly initiate a recall on this dangerous problem.

My only complaint would be why hasn't their been a recall on any Titans that are having cracked exhaust manifolds, which cause check engine light and very expensive repairs.

I found my truck has 3 recalls that need to be done. But my exhaust manifold is also cracked I have heard of this bing a known problem as well. It has been cracked and leaking for a while but I haven't been driving it to much seens it's been leaking.

The contact owns a 2006 Nissan Titan. The contact stated that the odor of exhaust was present inside the cabin of the vehicle. The vehicle was taken to the dealer who diagnosed that the problem was due to a cracked exhaust manifold. The vehicle was not repaired. The manufacturer was notified of the problem. The failure mileage was 50,000.

Cracked exhaust manifolds. Both at the same time.

The exhaust manifolds crack and cause emissions leaks.

Was told during yearly state vehicle inspection that it would not pass due to cracked exhaust manifolds on both the driver's and passenger's side. I was 19 days out of warranty, but almost 23,000 miles under. This is a pleasure use truck that averages roughly 7000 miles per year and sometimes isn't driven for weeks. I have had it serviced by the dealership from the day I bought it. Sought assistance from Nissan America but was declined without explanation. It's clear that both did not crack after the expiration date of the warranty. It is also clear, based on only a few minutes of internet research, that this is a widespread and well published problem. The fact that it won't pass a state inspection speaks to the danger of serious personal injury due to exhaust fumes entering the cabin. Why have you not forced a recall? the manifolds being replaced have no design improvements to prevent future failures. Nissan needs to be forced to correct their design issues. Replacing failed parts with identical parts, that are sure to fail, is nothing more than retaliation for being forced to honor any sort of warranty and a "gotcha" to the consumer.

Crack on the exhaust manifold on passenger side.

Exhaust manifolds cracked leaking asked Nissan for help was rejected had manifolds replaced with aftermarket parts which cost 1/3 the price of Nissan work done by a master Nissan tech.

Both passenger and driver side exhaust manifolds are cracked and exhaust fumes are entering cab while driving causing engine check light to stay on and engine running rough.

Tl- the contact owns a 2006 Nissan Titan. The contact stated that upon inspection, it was found that exhaust manifold was cracked. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 80,025. Kmj.

2006 Nissan Titan exhaust manifolds cracked again. Fixed at dealer at 62,837, replaced both exhaust manifolds with new ones. Now at 118023 manifolds are cracked again, out of warranty and dealer will not replace. This is not a cheap repair somewhere around $2900 to fix both. I have heard many other complaints about this and had I known previously I would not have purchased this vehicle. Nissan replaced the faulty manifolds with the same new faulty manifolds.

Ticking noise from engine area especially under moderate acceleration, dealer inspected and said my exhaust manifolds are cracked and would cost 3k to fix . Nissan customer relations refuses to help in any way even though my truck is only 4000 miles past mileage limit. This is a known issue that is a safety hazard (exhaust fumes can enter cab) and Nissan refuses to take any responsibility.

The contact owns a 2006 Nissan Titan. The contact stated that an abnormal noise emitted from the exhaust system. The vehicle was taken to the dealer for inspection where the contact was advised that the exhaust manifold was cracked due to defective material. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 75,000 and the current mileage was 85,000.

The contact owns a 2006 Nissan Titan king cab. The contact was traveling 35 mph when a noise emitted from the engine. The vehicle was taken to the dealer who confirmed that the exhaust manifold was cracked and needed to be replaced. The manufacturer was contacted but the vehicle was not repaired. The failure mileage was 99,300 and the current mileage was 99,400.

Driving cross country in Nissan Titan. Truck floor got hot at one point. Later truck sputtered and shut itself down. I let it cool down and it drove fine for a while. Next day all of us in the car were a little sick and nauseated. Car drove fine the rest of the trip and it wasn't until after we arrived at our destination that the check engine warning light came up. Looked up the codes which were that the catalytic converters had loss efficiency. I took it to the deal for a complete diagnosis. Dealer confirmed all 4 cat converters were dead and it probably caused by a leak in the exhaust manifolds. Further research shows that Nissan Titans have a history of cracks in the exhaust manifold. This not only ruins the cat converters but exhaust fumes leak into the cabin causing a health risk. This is a known issue and I have contacted Nissan about this but have not heard back from them yet.

Left and right side exhaust manifolds are cracked. They are normally covered under the emissions warranty of 8yr/80k miles. I am out of warranty by 4,000 miles. I put 4k miles every 3 months and I have heard the ticking noise when the vehicle is cold for over this time period. I contacted Nissan USA for loyal customer assistance and was denied. I filed an appeal and was denied within 2 hours. I have owned (3) Nissans in the past 7 years and expect some compensation. This is a major problem on all Titans 2004 to 2007. This should be under recall for exhaust gases getting into the passenger compartment.

The contact owns a 2006 Nissan Titan. The contact stated that the passenger side manifold was cracked. A loud exhaust noise could be heard from the front passenger side of the vehicle. The failure existed for the past two years. An independent mechanic stated that the exhaust manifold was cracked and needed to be replaced. The vehicle was not repaired and the manufacturer was not notified. The VIN was unavailable. The approximate failure mileage was 117,000.

I have a 2006 se Nissan Titan truck, my concern is I just found out from my local dealer that I have a exhaust manifold leak. The main reason for my concern is. . . How this came about was because I was and still am getting exhaust fumes into driver compartment which in return gives me headaches, and on two occasions caused serve dizziness. When I explained this to the dealer the said there was nothing they could do! I have two children who I drive to school, I don't need them getting sick from these fumes from which I experienced! I'm asking for some kind of help!.

2006 Nissan Titan only 35,000 miles and both exhaust manifolds cracked and were leaking exhaust gases that could not be fed into catalytic converters. . Dealer replaced under emissions warranty since exhaust manifold/catalytic converter are a solid 1 piece unit. They replaced with identical defective pieces that I am positive will crack like the original ones. . Please check online Titan forums and you will see it is a very common problem with almost every Titan. . My local dealer says they "automatically check every Titan" for this issue. . I believe this should be a recall campaign because it is so common and not from driver error/abuse, and once any Titan is out of the 8 year/80000 mile coverage it is a very expensive repair totaling over 2,000 dollars! most Titan owners report a ticking sound from under the hood especially under cold start up-I didn't notice this on mine so I had no idea mine were cracked that's why I believe there should be a recall to inspect as many Titans as possible for this emissions issue.

The contact owns a 2006 Nissan Titan. The contact stated that while driving 55 mph, he could smell gasoline as the vehicle exhibited an abnormally loud clicking noise. The vehicle was taken to a dealer for diagnosis where the contact was informed that both exhaust manifolds were fractured. The vehicle had not been repaired. The failure and the current mileages were 135,000.

Noticed loud banging in rear of truck. Found the exhaust tailpipe broke off near the muffler and was hanging by a mounting post. Upon inspection after removal of the tailpipe from the underside of truck, it looked like a junction of the tail pipe to the muffler pipe had completely rusted through.

Both exhaust manifolds are cracked requiring replacement. Their failure emitted raw engine exhaust into the engine compartment potentially endangering the life/health of the vehicle occupants due to carbon dioxide exposure through cabin air inlets when the windows are down. At the very least, air pollution in violation of the epa occurred multiplied by the vast number of documented Nissan exhaust manifold failures across the country.

I bought this Titan at tri-state Nissan in winchester, va. My brake rotor were completely rusted due to bad metal used - I had to replace them at 30,000 miles. My left rear wheel seal was defective and started started leaking fluid at 70,000. Had to replace even though I had extended warranty. Catalytic manifolds went bad and they knew it when it was under warranty - but they didn't replace them. Paint problem when the truck is cold - big giant spots in the clear coat. The manifolds manifolds need to be recalled because the exhaust is entering the vehicle.

My 2006 Nissan Titan was taken in for recalls. Upon completion of the work, which was poorly performed, I was notified that both of my manifolds were cracked and would need to be replaced which would cost me over $2,000 but the dealer would cut me a deal for $1,700 if I wanted to do it right away and they also threatened me with the fact that I would not pass my smog so I had to do it now. I declined as I could not afford repairs like that. After a short search online I found that this was a regular issue with Titans but was not submitted for a recall. I have also sent a complaint to Nissan. I am quite disappointed with this issue as well as the lack of service I have received from the dealer. My family and I have always been strong supporters of Nissan and own many of their vehicles and have never had issues like this that have not been able to be resolved. I will continue to buy Nissans but hope that this will be reviewed and claimed as a recall. I cannot afford the repairs as my husband and I are both currently unemployed with 4 children and this is our only vehicle which we can no longer drive because we cannot have it smogged to renew registration. There is no doubt in my mind that the manifolds had been cracked for some time prior to the visit to the dealer. We had always taken our truck to the dealer because we had purchased a gold package for maintenance and I had complained about noise before and they could never find a problem. It figures that as soon as it is out of warranty they would magically find the issue.

The contact owns a 2006 Nissan Titan. The contact was driving approximately 55 mph when the engine exhibited severe hesitation without warning. The vehicle was taken to an authorized dealer for diagnosis, who stated that the exhaust manifold was fractured on both sides. The vehicle was in the process of being repaired. The manufacturer was not notified of the defect. The approximate failure mileage was 150,000. The VIN was unavailable.

I own a 4x4 loaded 2006 Titan le which is my primary family vehicle. Around 80k, ecm module went out causing car to stall out and lose all power in the middle of traffic (with my kids). Lucky not to be nailed by an on-coming car, I had the car towed to the dealership and module was replaced due to recall. One week later while vacationing in the mountains the battery randomly fried, we replaced it. However immediately following, the anti-theft alarm would randomly sound off, the dvd player wouldn't work (hasn't worked since), the sunroof was malfunctioning and wouldn't open and close properly. Once we returned, the dealership couldn't find anything wrong (except the dvd player, which no one could explain). About two weeks later the check engine light came on and we found that the first catalytic converter on the passenger side had blown. . Followed not long after by cracked exhaust manifolds and the drivers side catalytic converter bad. . Dealership wants $3000 just for the catalytic converters!!! I should not be responsible for the cost of replacement! this clearly is a manufacturers defect and not a isolated case, Nissan must do something about this! I hear rumors of a class action. . . It is a huge safety hazard!! I'm hoping they do the right thing and just fix it, without having to get lawyers involved.

The contact owns a 2006 Nissan Titan. The contact stated that while driving 30 mph, he heard an indescribable noise coming from the vehicle. The vehicle was taken to an authorized dealer where the contact was informed that the intake manifold was cracked. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

The exhaust manifolds are notorious for cracking on Titans, causing exhaust fumes to enter the truck cab. Very dangerous, loud and obnoxious. Un converted exhaust is leaking into the atmosphere so this effects the emissions laws. The manifolds are one-piece with the cats by the way. They should all be replaced due to extremely poor design and failure rate on many Titans on forums such as Titantalk. Com.

Leaking manifold; this part was recalled by Nissan but upon completion of form, I was informed they calculated the mileage to be beyond their warranty. The left side manifold was replaced at my expense. Now the right manifold has cracked also and is leaking exhaust fumes. Nissan is aware that I have the left side manifold for their inspection and their local dealership, where I purchased this vehicle, confirmed the right is also cracked. This is a danger and definite hazard due to the exhaust fumes and possible fire yet Nissan has declined any assistance in reimbursement or assistance in replacing the right side manifold due to their calculation that the mileage was beyond their warranty coverage. I could not find records as to the mileage when I replace the left manifold. The mechanic informed me when he replaced the left side manifold that he would expect that the right to do the same.

Tl-the contact owns a 2006 Nissan Titan. The contact stated that while driving approximately 50 mph, the contact depressed the brake pedal but the brakes failed to work immediately. The contact was able to stop the vehicle after a ten second wait. The vehicle was not diagnosed or repaired. The contact also noticed an abnormal noise and leak from the exhaust manifold. When the accelerator pedal was depressed, the contact noticed another abnormal noise from the converter. The vehicle was taken to the dealer and diagnosed for an exhaust manifold failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 65,000. Sms.

Exhaust manifolds left and right cracked and leaking less than 1 mos out of warrenty Nissan refused any assistance. I was a Nissan parts mgr for 50 yrs no consideration. When my wife needed a new car for her 2001 sentra we purchased a Mazda cx5 instead of a rouge.

Repeated cracked exhaust manifolds which can leak dangerous and lethal exhaust fumes and carbon monoxide into the cabin interior.
