Windshield problems of the 1999 Nissan Frontier

Problem 1) difficult to start when engine is hot and truck has sat for 1-4 hours problem 2) vibration in driveline under light acceleration in overdrive and when truck bed has weight in it viration occurs all the time. Dealer had truck for three times before deciding to shim the rearend which has not helped any. I believe the problem is with Nissans brand new transmission that is in this truck but it seems they dont want to accept that fact. I have gone as far as to have a Nissan engineer from denver look at this truck but still no fix. Problem 3) passanger side door glass is loose in the frame and rattles-dealer has not yet been notified about this latest problem on the crappy truck. Also to let you know there have been problems with the brakes that the dealer managed to fix after the 3rd trip for repairs.
