Design flaw on Nissan Titan due to exhaust leak which will then burn the electrical wiring and the truck will stop all of sudden with lost of power and brakes, which may cause accidents. We were on our way back from camping trip with travel trailer in tow. On interstate 81 near wilkes barre, pa...we were going 65 mph and all of a sudden the vehicle engine stopped, we had a lost of power and brakes and had to cripple towards the shoulder and couldn't start the engine again. What caused this failure is the tail pipe came loose due to rust and the heat from the exhaust burned the electrical wiring that was placed alongisde the exhaust causing the engine computer to malfunction. We had to pay $1,300 to get the vehicle repaired not including one night hotel stay and renting a car back home because the part was not available for a few days and having to drive back up to pick up the truck with the travel trailer and bring them all back home. The distance is 156 miles from where it broke down to where we live. I believe there's a design flaw that could be dangerous. This is not the first time it happened, service manager in wilkes barre acknowledged several other Titans with the same problem when there is an exhaust leak as well as our local Nissan service manager acknowledged the same. Nissan should have protected the wiring in the exhaust area with heat shield of some sort. Exhaust leaks over time, it's the nature of the exhaust but it should not require customers to pay $1,300 to get the electrical system repaired. I have reported this to Nissan Consumer Affairs asking for assisting in the repair cost due to design flaw, they declined assistance indicating that it is my negligence that the tailpipe separated from the muffler. No other cars on the road with a dangling tailpipe needs to have electrical wirings replaced because of that, it's because they don't run the wirings parallel to the exhaust.

1. truck will randomly stall while running or in idle position. This occurred starting around March 1st of 2010 and increased in occurrence up until it was towed to northern auto of berkeley Michigan the morning of May 28th. The vehicle had been in to northern auto twice between March 1st and May 28th, but could not be fixed because the problem could not be replicated by their mechanics. When it was towed in the morning of May 28th to northern auto, they were able to replicate the issue and recommended it be taken to the Nissan dealership. The vehicle was towed from northern auto of berkeley Michigan to the Nissan dealership of troy Michigan on the afternoon of May 28th of 2010. 2. the stalls would happen sporadically while driving at speeds below 40 mph or idle. The vehicle would lose all power, hence rendering the power steering and brakes useless. This did not cause any accidents but has the potential to do so, because the vehicle loses significant stopping and steering power while still moving. At one point the vehicle completely shut down while traveling at approximately 30 mph. 3. the Nissan dealership of troy Michigan reported the problem was a faulty ECM relay on the internal power distribution module (ipdm). The dealership recommended and is replacing the entire ipdm.

Nissan ipdm (intelligent power distribution module) which houses the fuel pump relay will inadvertently shut off power to the fuel pump. It has happened to me from a parked vehicle and has also happened to me while I was driving down the road. There is no timed sequence as to when this happens, but when it does you lose power to the vehicle immediately. The vehicle will re-start after sitting for 10 minutes, but may cut out again 15 minutes later.

I own a 2005 Nissan Titan king cab, which I purchased it in November of 2005. After, approximately 30days of ownership and 500 miles of travel; the front brakes began to experience complications (they would shudder while braking and create an unreasonable amount of brake dust.) I quickly return to my local dealership where I purchased it, for servicing. The Nissan dealership repaired the rotors. During the summer of 2006, I began to notice a musty odor emitting from the floor and carpeting of the passenger side. During a routine oil change and requested the mechanic to inspect the truck for the cause of the odor. They couldn't locate the source of the odor. I returned the truck to the dealership for the same problem on several other occasions, during the summer of 2007 odor reappeared; they replaced the rubber gasket around door windows in hopes of resolving the issue. Meanwhile the front brakes rotors were replaced again and the gauges (fuel, oil, tach, voltmeter) acting erratically. The dealership repaired the brakes under my extended warranty & prorated my purchase of a new Nissan auto battery; according to service dept. This was the cause of the gauges malfunction. Then again IN2008, I was told the brakes were no longer under warranty and that the musty odor was caused by water coming into the cabin via a small void in the window sealant around the "factory installed windshield' upon hearing this, I chose to take my truck to another mechanic due to Nissan mechanic inability to resolve the brake issue & locate the source of the water. This year 2009, the rear end was repaired due the seals leaking on the driver's side and preventive replacement on the passenger seals. However, a few old issues along with new ones that still exist. My new mechanic told me the source of the water & odor issue is the A/C condenser leaking into the cabin, the blinking air bag indicator light was due to a harness needing replacing in the rear doors.

Column shifter causes damage to wiring harness of the manual mode transmission button. When shifting vehicle into drive, column hits wiring harness, and over time causes wiring to the transmission manual mode button to break. Once this breaks, there is no means to down shift vehicle, causing a hazard especially when traveling roads where there are elevation changes. Was able to determine the cause of the manual mode button failure by researching Nissan Titan forums (club Titan and Titan talk). Upon removing steering column shroud immediately noticed chaffing of the wiring harness, and the broken wire. Contacted Nissan, was given file number 6550464, Nissan was not concerned with this issue due to the age (currently 4 years) of the vehicle.

The contact owns a 2005 Nissan Titan. The interior lights on the instrument control panel failed repeatedly. The dealer diagnosed the electrical failures 38 times. The over drive which is electrically bolted behind the transmission unit failed to engage and as a consequence the vehicle is unable to shift into gear. A technician from an authorized dealership replaced the wiring harness which has not sufficiently remedied the electrical problem. The vehicle has exceeded its warranty and the contact would be liable for the repairs. The manufacturer stated that they would not provide him with any assistance. The failure mileage was 500 and the current mileage was 57,000.
