Filed Jan 8, 2024 · CA

Hello my truck exhaust manifold had a crack and was leaking exhaust fumes, the good thing there was a recall and Nissan dealership replaced it but now the other manifold is leaking carbon monoxide into my cabin making it on save to drive. I call the dealership but the recall is over and my truck dose not have warranty.

2005 nissan titan 121k miles. Cracked exhaust manifold causing a exhaust leak. There is a strong exhaust smell in the cab when traveling at slower speeds (under 35mph). It has been so bad at times it makes you light headed and sick to your stomach. This could cause someone to pass out while driving causing them to loose control of their vehicle. Defiantly a safety hazard! Also causing a decrease in gas mileage as well as a loud knocking/puffing noise upon acceleration. I have searched the internet finding 100's if not 1000's of complaints about this! Why has this never been recalled? The safety issue alone should warrant a recall, its obviously a faulty component!

My nissan titan has roughly 31,000 miles on it over the last 12 years . The exhaust manifold is cracked . I did a search to see if this was a known problem and there are tons of complaints and pictures on the internet so I was amazed to see that there are no recalls . Many people have had the issue taken care of under the 8 year 80,000 mile emissions warranty . The only problem is many people ( including myself ) are past the 8 years even though way under the mileage . My truck is practically brand new inside and out and has been sparingly used and still now I have harmful exhaust fumes leaking out and the truck is robbed of power .

The exhaust manifolds are faulty and crack allowing deadly carbon monoxide exhaust gases to enter the cab of the truck while the vehicle is in operation. This could cause the driver to lose consciousness and crash. It was only after my 6th long road trip (3+ hours driving) did I discover I was being poisoned by carbon monoxide. I took my truck to an exhaust repair company and as soon as I mentioned my vehicle the technician told me he was 99% sure I had a cracked manifold. He later confirmed this with a diagnostic test which revealed both manifolds cracked and leaking exhaust fumes into the cab. This could have killed me just sitting in a parking lot! I thought I was just getting bad headaches from the long drive and my nausea was from the extreme headaches. After this happening so many times I knew there had to be more to this. Think about somebody driving, being poisoned to the point to where they pull off the road to rest and try to sleep off their headache in a running vehicle to stay warm and end up dying. Nissan needs to fix this. I don't want a new defective manifold, I want a fix!

The other day I was sitting in traffic for almost 30 min stopped with the engine running (lots of christmas traffic on the 5 south freeway), I put the truck in park because I notice an accident. I had my windows up and my cabin air on. Then a few min later I started feeling dizzy almost fainting. The car next to me saw that I was struggling, came to my window and asked me if I was ok. I rolled down my window and he noticed the smell of exhaust inside my truck. After my headache went away. I went to the dealership and they told me both of my exhaust manifolds were cracked and that's how the exhaust was entering near the front cabin.

Exhaust fumes in cabin due to cracked exhaust manifolds. I only use the truck for family trips, and on the last trip I notices a ticking noise coming from the engine, especially when cold, I also noticed exhaust fumes in the cabin when the truck was at a light or a long stop sign. I am the first owner of this truck and after some research it looks like this is a common problem with nissan titans but the worst part is that the replacements have the same issue, so now I can not use this vehicle. Looking to see what is the best permanent solution.

The passenger side exhaust manifold developed a crack and leaks exhaust fumes. We had the truck into the dealership several times complaining of an exhaust leak; however, the service department advised they could not locate any leaks. We had a family member, who is a mechanic, look at the truck recently and he located the crack in the underside of the exhaust manifold. This condition could leak exhaust fumes into the passenger compartment of the vehicle causing a dangerous situation.
