2006 Toyota RAV4 wipers, windshield & visibility problems

On freeway, other motorist notified me my car was "on fire!" I saw excessive smoke in rearview mirror. I took the next exit which was dixon, ca off interstate 80 west in california. The side of the freeway there is grassy, did not think it was safe to stop...I stopped the car and smoke was everywhere, coming up through the hood & under the car. This was tues, 2/3/09. I has the car serviced the fri before, 1/30/09 at toyota vallejo in vallejo, ca. I called the dealership after calling aaa for a tow.

Driver visor unexpectedly fell down into drivers view while driving down freeway. It could not be moved to the side to stay out the way either as it seems to have just stripped out.it had to be removed completely in order to see out windshield properly. The same thing occurred on the passenger side about 2 weeks later. This creates a driving hazard both by the unexpected dropping of the visor creating a viewing obstruction and by not using the visor also because of glare from the sun.
