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.

Noticed upon starting the vehicle, a clicking sound which became louder when driving. Vehicle was under warranty. The dealer stated the exhaust manifold was cracked. They fixed it. Shortly after the other exhaust manifold cracked and they fixed that as well. Since then, the warranty has expired and either one or both exhaust manifolds have cracked again. I was told it was going to cost literally thousands of dollars to repair. Unfortunately, I can not afford to repair the vehicle. I was upset, but was willing to accept the situation, until one morning I got a strong smell of exhaust in the cab of the vehicle. Being a mechanic, I had my hunches. It doesn't happen all the time, but on occasion I get exhaust emission in the vehicle. I have also recently found online that there are an abundant amount of other Nissan Titan owners complaining of the same thing. There is also the possibility that if the leak is around any wiring, the hot gas may cause the wiring to melt causing a possible engine fire. That of course is just an educated opinion. How many more exhaust manifolds have to crack before Nissan will admit they are a defective design. Is it about the money to recall the vehicle or is it about safety after all? in addition, I would have completed this form a lot sooner, but I was just recently informed about it. The vehicle obviously has more wear and tear and more mileage, but the fact remains that this happened many miles ago. Thank you for taking time to read my letter.

While waiting for my wife to come out of a store with truck running I noticed a light flickering in the store window. My wife came out of the store and got into the truck. While backing out I noticed the flickering light in the window coming with me. When I stopped the truck I noticed smoke coming up over my hood then the cab of the truck started to get warm. I noticed a burning smell and told my wife that I think my truck was on fire. I got out of the truck, went to the front and saw the condenser fan motor on fire. I was able to extinguish the fire with a can of coke that was on the ground. A little while later it flamed up again and had to get a bucket of water from the store clerk. The fire caused over $4100 in damage. I had a recall on this condenser fan motor, had it taken care of in February 2012. Caught fire on 09/02/2013.

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.

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 Nissan 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.

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.
