Vehicle exhaust manifolds on both sides cracked.

- Kingwood, TX, USA

Exhaust manifold cracks. The exhaust manifolds on Nissan Titans are defective. It is well documented that the majority of owners of Titans have, had or will have the issue of a cracked exhaust manifold. This is a dangerous situation, as an exhaust leak could introduce carbon monoxide into the cabin area with is lethal. There are forums that this issue is discussed well in detail requiring the owner to foot the bill for replacement at a price around $2500. If you contact Nissan, they will not acknowledge that it is a defect, except in reality they know because they have made subsequent changes on newer models to address the issue. They don't want to take responsibility for earlier models. You will not know if carbon monoxide has entered the cabin and could kill you in minutes. This is a serious safety issue. A recall needs to be issued in order to save lives and make Nissan responsible for defective products. This applies not only to Titans, but armadas as well.

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.

Cracked exhaust manifolds both sides. Noticed it around 60000 miles. Vehicle purchased from dennis dillon Nissan boise Idaho. Dealer has been no help as of yet even though the catalytic system has a 8/80 warranty.

- Mccall , ID, USA

Please issue a recall for the defective exhaust manifolds for the Nissan Titans. I know that there is a warranty up to 80000 miles but my truck is over that mileage. This is a known factory defect that can be very dangerous due to exhaust leakage.

After having ipdm module replaced (campaign number 10V517000), the ses light showed bad catalytic converters within a few thousand miles. The ipdm module failed before being replaced and it caused raw fuel to be dumped on the catalytic converters which caused them to fail. I think Nissan should be responsible for the cost of failed catalytic converters when their faulty part caused the damage. This is an expensive repair ($2,800). After looking at forums on the internet, I see many people having issues with the Titan catalytic converters and having them fail before the vehicle reaches 100K miles. I filed a complaint with Nissan and they would not help with the repair. They said the faulty ipdm would not cause cats to fail.

Truck in mid 50's randomly stalls at highway speed and will not restart. All symptoms identical to every other of the many thousands of complaints of ECM/ipdm failure. Nissan claims relay for recall was changed in 2011, that we have no open recall and no other recourse other than to call Nissan America--even for just a replacement relay that costs them pennies. Nissan America says the local dealership must rectify the problem. These huge trucks are stalling at highway speed all over the country. I specifically asked my local dealer to check for this known issue the last time it happened and they kept my truck for a week and changed the battery terminals--for $400 instead of checking the $4 relay. That's retail--it costs them about a quarter. Even with the.3 hours of labor, it would have been under $90 for me at full retail. Instead, I stalled again at highway speed 3 weeks later. I do not believe for a minute that there have been no deaths directly related to this problem. How has there not been a full investigation and news reports of this frequently reported problem?

Loud exhaust sound coming from the front, on both sides for the engine compartment. Due to a cracked manifold. I could also smell exhaust fumes inside. I keep the window cracked open when I drive for safety reasons, mostly when I have my wife and kids in the vehicle.

Radiator began leaking and had to be replaced due to cracks/separation of plastic components.

- Clearwater, FL, USA

While driving my truck home from work, I noticed the sound of the exhaust became progressively louder. I parked the truck for the night. Prior to leaving the next morning I tried to locate the source of the increased noise. However, I noticed after starting the vehicle the noised would decrease. Therefore, I took the truck to my mechanic for diagnosis. He told me that the header on one side is cracked and the other header on the other-side shows signs of stress. Also, he explained this a common issue with the Nissan Titan and I might want to explore my repair option with the local Nissan dealership. However, after discussing this issue with the Nissan dealership, I was told there is no recall for the notorious issue and the cost of the repair is my responsibility. Upon hearing this, I decide I would lodge my complaint about this issue here.
