My 2004 Nissan Titan rear diff seals leak and has caused a brake failure. I pulled out of my driveway and was driving down the road when all of a sudden my rear end locks up. It took a few moments to get her going again in reverse. I jacked it up and removed the tires and removed the rotors. The pad on the emergency brake system fail off. It still had plenty of pad left on it. My father looked at it and noticed the fluid leaking from my rear end. He told me that probably caused the failure due to the contamination. Replaced the pad and added some oiled to the rear end. I have researched this issue online and found numerous complaints about this and other brake failures also. There should be a recall for this issue. My exhaust manifold leaks also. I am replacing it too. This is a known issue with the Titans. This may be of more concern with the epa. They have been know to crack.

I have had an odd exhaust sound from my Nissan Titan for over 18 months. When I finally took it into the dealer both exhaust manifolds were cracked and repairs cost $1400. I was told a the dealer and at several muffler shops that this is a very common defect due the cast nature of the manifold and the excessive weight of the catalytic converter welded onto the manifold. The replacement part were a new design and the dealer said they will not crack. Since my truck had 105,000 miles on it when the service was done there is no warranty coverage. I feel that this is a design flaw with the 2004 and 2005 Nissan Titan pickups and the cost of repairs should be borne by Nissan and not by the consumer. I am hoping that there will be a class action suite filed on the consumer's behalf either by an individual, the state or the federal government.

The vehicle ( a 2004 Nissan Titan) has 30 thousand plus miles, carefully maintained (no salt) and was pulling a 7500 pound boat on pa I-79 when it lost all power, including all lights (including rear and hazard).this resulted in a fire which totally disabled the entire vehicle. The tail pipe had fallen off and burned dozens of electrical wires. This manufacturing defect has been reported numerous times on the net and to dealers. It should strongly be noted that had the same incident occurred on NY I-90 where there is no safe place to pull off or at night anywhere, many lives would have been lost. This defect must receive immediate attention. Nissan has refused to acknowledge the defect or pay for repairs.

The tailpipe fell off of my truck. Resulting in the hot exhaust to be vented onto a rear wiring harness and thus melting it. Along with the melted wiring harnesses, the ECM and mass airflow sensor were shorted out and need to be replaced. This will be over $2000 to fix and will be paid for straight out of my pocket. The warranty does not cover exhaust because it supposedly is a regularly maintained part. This truck is a 2wd model with 305/50X20 wheels/tires, so it obviously is not used for off-road purposes nor has it been used to tow anything. When the tailpipe broke, the truck was being driven down a smooth black top highway and nothing was ran over in the road such as an animal or debris that would cause the tailpipe to fall off. I bought this truck used but with only 30K miles on it and only drove it 1500 miles since purchasing it.
