 I was initially excited about purchasing a 2006 Titan; however, on my way home from the dealership the vehicle started to experience brake problems and a vibrating steering wheel.  This vehicle has already been in the shop three times, all four rotors and pads have been replaced--to no avail.  Nissan has been uncooperative and the dealership is incompetent.  On paper, the specs look great, but I'm seriously concerned about the safety and reliability of this truck.  I've also started experiencing engine hesitation and rattling from underneath the bed.  This is my second and last Nissan.  I performed some research on the internet and these problems appear somewhat common.
