2003 Nissan 350Z transmission problems

Tl*the contact owns a 2003 nissan 350z. The contact purchased the vehicle only for long distance driving. As soon as she began driving the vehicle, she smelled rubber inside the passenger compartment. The dealer stated that the smell would dissipate and was present because the vehicle was new; however, the odor remained. While driving 60 MPH, the vehicle would not shift from second into third gear. The failure occurred without warning. The vehicle coasted to the side of the road and was towed to the dealer.

Bought a 2003 nissan 350z used from keyes nissan of woodland hills,ca. Tiptronic (auto/semi-manual) transmission needed to be replaced within 45 days. Now a whining noise that is still not fixed as well as excessive heat from shifter area that causes passengers to sweat & scalding hot to touch. Car hasn't seemed to run right since. Seems every 350z owner has the same atypical problems-tire feathering, transmissions replaced,rear axles, power window motors fail(the last 2 are my next trip to the dealer).
