2010 Infiniti G37 Other or unknown Problems

“The car has an erratic shifting of the 7-speed automatic transmission.

“Top of dash becomes extremely shiny and sticky after 1 hour of sunlight through the windshield casing unwanted glare in windscreen. Temporarily can be cleaned with soap and water and returns to dull non sticky appearance, but only temporary. Next time car is in the sun for about an hour of driving or parking, the the shininess and stickiness returns causing massive reflections in the windshield.
