Whether stationary or moving, the ac blower, defrost, etc won't work as it always runs cold and does not blow any hot air to defrost windows. This is especially problematic when car is foggin up on the inside and the defrost won't blow any hot air. Cabin of truck is especially cold now as it won't blow any hot air. There is a clicking sound when tying to turn the ac/heater control knob, like the blower door is stuck or the motor can't turn the door to let the hot air in.

I recently had air bag light start flashing. I took in to Nissan dealer to get checked and they said the "spiral cable" was bad, this is also known as clock spring. Nissan reset and said bring back if occurs again. It did and I took to another shop for second opinion and same result. I agreed to get part to fix the truck. After being told part was on back order no eta on delivery of parts from Nissan. After 4 weeks I checked and found out the same dealer has 6 other "spiral cables" on back order. As I stand now, according to Nissan my trucks driver side air bag will not deploy if needed, and no eta on parts.

Clicking noise coming from dash when switching from defrost to vent, then again after vehicle has shut off (last 10-20 seconds worth of "ticking" noise ), has done this since I had purchased it. Now there is no heat when heater is turned on, blows cold air. In reading forums, I am not the only one. This needs to be recalled. I saw the voluntary service campaign, but in talking with my Nissan dealer, they say this only goes until 72K. Kind of convenient when im at 73K.

During a road trip from fl to NY, I noticed a faint rattle underneath the truck but didn't think much of it. During that trip, I noticed my tailpipe didn't look like it was positioned properly. It was loose! the muffler to tailpipe mounting flange had completely rusted away from, which is apparently a common problem (reference blogs; titanspot, titantalk, clubtitan). I threw the tailpipe in the bed and kept driving. Throughout that weekend, the vehicle operated normally without any issues. On our return trip from NY to fl the vdc off, slip and ABS lights suddenly came on with about 100 miles left in the trip. The vehicle would not activate cruise control and 4WD wouldn't engage either. Brought truck to the dealership in coral springs, fl for what I thought would be warranty service, considering I had the gold preferred Nissan extended warranty. I was informed that exhaust components were not covered, and since the 'non' covered components caused electrical & sensor failures, they wouldn't warranty any of those components either. The heat damaged the plastic conduit, wires in the harness and the ABS wheel speed sensors (and associated wiring). Not to mention, dangerous exhaust gases can accumulate under the cab & bed of the truck without a proper means of exhaust routing. This is the third Titan I have owned. All 3 (2005, 2006, & 2010) have had the exact same failure at that exhaust flange. This vehicle was the only one that experienced corresponding electrical & sensor failures. Nissan must admit there is a problem with this flange connection design and materials. It is a poor design (when it fails, exhaust gases are pointed upward at the truck bed and sensitive electrical wiring). For Nissan to ignore this defect is unacceptable. A straight connection, or better flange materials would go a long way in rectifying this recurring problem.

They have been making Titan ics since 2004 and there have been re calls due to the trailer brake control circuit failing due to bad body control modules. I believe all Titan ics need to be re called for this issue. My Titan ic will not work with 2 different brake controllers by 2 different manufacturers. Best to not attempt to tow anything that requires a brake control due to this on going problem for any year Titan ic. 2 bad for me it is out of warranty by a few months and the re sale value is very low for all Nissan due to poor quality.
