Titan 4WD 8-cyl

  • 50,000 miles
About two years ago I started hearing a ticking noise on my 2005 Nissan Titan pu at start up. Couldn't for the life of me figure out what it was until Nissan sent me an owner notification card about cracks in the exhaust manifolds. Then it dawned on me what that ticking noise was when cold start up took place. I had the vehicle recently in the shop for 2 other recalls and mentioned this along with the notice I received about this problem from Nissan. The service manager said they would look into it but was concerned because I had 83,400 miles on the truck and warranty issues only would fix this up to 80,000 miles. I haven't ever had a exhaust crack on any vehicle that I have owned since 1972 and had some of these vehicle to upward of 250,000 miles. Why won't Nissan do something about this to fix this issue because it looks like it is all of them that crack. Seems to me for safety issues and exhaust fumes that should be routed to the rear of the vehicle are now being pushed into the engine compartment and not even getting to the catalytic converter. I'm very disappointed in Nissan for the absence of help in this issue and a serious one at that. This should be a recall and of all the watchdog areas of our life where is the epa on this one.

The contact owns a 2005 Nissan Titan. The contact stated that both exhaust manifolds cracked and the contact noticed that the vehicle had become very loud. There was also a fuel odor inside which alerted her to a potential failure. The vehicle was taken to a local mechanic who stated that the manifolds were cracked and would need to be replaced. The vehicle was repaired at a later date. The contact called the manufacturer who offered no assistance. The current mileage was approximately 100,000. The failure mileage was approximately 74,000.

My exhaust manifold/ cat has failed. There is a crack in my exhaust manifold and over warranty 15K. I have notice mpg loss and gases entering my cabin when I'm at a stop light and my window is down. I'm a father of 3 and worried for my children safety. Passenger is cracked and worried that the drivers is going to go soon. The dealership will not cover under warranty. This will cost me 600 per side + 600 for labor which brings the total to 1800+tax. I'm apart of a Nissan club/forum and this is a problem numerous people are having, 50+ in California. Some people have to go aftermarket or even pass it illegally through black market channels. Nissan is well aware of this problem and released a revised version which still have the same problem. Nissan is robbing their customers and need to be brought to justice. They should be responsible under the emissions law and for putting out a known faulty part. I don't know what to do I have many friends in other states that are on their 2nd set or going on their 3rd set. This should be addressed for the safety of people and the earth [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Exhaust manifold leaking for the second time. Bank 1 side was bad before the 80 emissions warranty was up, however dealership wouldn't do it, so we purchased another oem manifold/cat and had another shop replace it. Now 2 years later that side has failed and is leaking again. The catalytic converter has failed on that side also. Nissan has not offered a recall. Exhaust manifold leaking allows exhaust fumes to not be vented correctly and the fumes can come into the cabin of the vehicle. I have spoken with the dealership and it should be noted I'm out of the 80 K emissions warranty. The oem equipment is not up to par.

Exhaust manifold leaking for the second time. Both sides were replaced under warranty and then 1 year and 8 days later I was told they were leaking again. Nissan refuses to cover under warranty. Exhaust manifold leaking allows exhaust fumes to not be vented correctly and the fumes can come into the cabin of the vehicle. I have spoken with the dealership and also filed a request with the main Nissan corporation.

  • 83,000 miles
2005 Nissan Titan le had an exhaust tailpipe separation at a weld. The hanger than holds the tailpipe is designed wrong. The weight of the pipe causes the exhaust gases up into the passenger side rear fender melting wires, plastic, and potentially anything in the cargo box area (bed liner melted). The tailpipe was not damaged in any way prior to the incident. I have found many internet forums with the same problem occurring to other Titan owners. I am confident if I would not have noticed the problem earlier and had combustibles in the cargo area, the vehicle would have caught fire. My right turn signal did not work and that is what made me look for the problem.

The contact owns a 2005 Nissan Titan. While driving approximately 55 mph, the contact heard a loud noise coming from the rear of the vehicle. The vehicle was taken to an authorized dealer where the technician replaced the rear differential. The repair expense was partially covered under the service warranty and the owner was responsible for the difference. Recently, there was failure with the exhaust system. The vehicle was being repaired, and the contact was unaware of the extent of the repair. The failure mileage was approximately 70,000. Updated 01/13/11 updated 01/24/11.

  • 75,000 miles
My 2005 Nissan Titan has two cracked exhaust manifolds. They are cracked into two pieces and are allowing carbon monixide to escape from the exhaust system adjacent to the cab of the truck. This is a potentially lethal failure due to co poisioning. Nissan has been contacted and will not assist with repairs, even though there have been hundreds of similar reported cases. My vehicle is out of the warranty period and I understand Nissan's reluctance, financially, to repair the failure. However, due to the potentially dangerous nature of the designed flaw that caused the failure I believe that a recall is justified. I am very willing to take the steps required to initiate a recall, but I am not sure how to proceed.
