Bought my Titan back in July and have enjoyed it. 2 problems with the Titan so far. 1 - Leak from the A/C drain into the passenger's side. Researching this has been a problem since 04 so should not have happened but did. 2 - Water leak from rear window. Took the dealer (Sheehy Nissan, MD) 3x's plus a call to Nissan USA to fix it. All in all no other problems and enjoy driving it. I have added a billet grille, chrome tube steps, tonneau cover and DVD system. Plan on keeping this truck for awhile.
Power, Power, Power. Truch if fun to drive and the power is there when you need it especially in traffic.
Some known problems that should be corrected before vehicles are sold. Check the TSB's and anyone can see that some problems have been around a long time and should be corrected at the factory.
