Tank Filler Pipe And Cap problems of the 2005 Nissan Titan

Purchased a new 2005 Nissan Titan 4-door pick-up truck in February 2005. Both the manufacturer as well as the dealership knew of an existing safety problem regarding the braking system of both 2004 and 2005 Titan pick-up truck models, but failed to alert myself of the problem. I had to threaten to sue the dealership to provide and install the manufacturer's suggested replacement parts to resolve the issue. The replacement parts were installed less than 60 days ago, and the problem has resurfaced. When I spoke with 2 separate Nissan corporation representatives, they provided me false information, and they told me they considered the matter closed and if I was not satisfied then I should contact a lemon-law attorney! I demand the manufacturer and the dealer to refund my money entirely! they fraudently sold me a vehicle that is not safe to be on the road. Additionally, 2 additional problems regarding the driver's power seat and the radio have surfaced and the both the dealer and the manufacturer have done nothing to fix these problems as well.
