2006 Nissan Titan: gas smell in the cabin

Both exhaust manifolds are cracked. I was under the impression that this was a recall. When I called they said it was only a warranty issue up to 80,000 miles.both were cracked well before the 80,000 mile. While waiting on the recall 80,000 has since passed. By doing some research I found that nissan knew about the defect but did not recall fix the issues. I would thing that an exhaust manifold would need to be recalled and fixed. This could case several issues such as the possibility of exhaust fumes filling the interior, also with the extreme heat coming from the cracks could easily ignite a fire in the engine compartment.

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.

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.

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.

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!

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.

The exhaust manifolds on my 2006 nissan titan have cracked, causing toxic exhaust fumes to leak into the passenger compartment. The truck has less than 100,000 miles. I believe this issue to be caused by faulty parts supplied by nissan.
