Problems with 2008 Toyota Highlander VISIBILITY

I have the sun visor on my toyota highlander that has fallen down and it doesn't stay up at all anymore. i am a single mother with three children and find this very unsafe because it obstructs my vision also when i look to the right or left i constantly hit my forehead on the visor that is constantly on the way. it is a hazard to me and my 3 children. *tr

My windshield wiper defroster started to crackle and smoke. i turned it off and back on and it started to do it again. *tr

The driver side sun visor keeps falling down. it does not stay up and impairs driver vision. *tr

The driver's sun visor does not stay up -- when either pulled back or pushed forward -- and falls in the driver's line of vision. this leads to a dangerous situation because it means the driver loses his field of vision for a few seconds at very unpredictable times. *tr

On 6/9/2010 asked dealer to ck. vehicle b/c air vents were throwing out white substance. dealer said the cabin filter was contaminated and replaced at 27,180 miles. on 12/9/2010 31,109 miles returned to dealer with same complaint white substance through vents. same response, cabin filter. i said how could filter be the problem after just 3929 miles, 6 mo service. dealer checked with toyota no record of issues here. we also own a 2007 lexus and had the same problem. on 1/14/2011 lexus service replaced the evaporater core with updated part as per tsb 0032-28. lexus said toyota dealer should do the same. toyota dealer has refused to replace. my concern, warranty expires in march 2011 and still having the problem. cannot continue to replace costly cabin filter. what should i do to get the repair completed? *tr

I bought a 2008 toyota highlander in december 2007. i did not test drive the vehicle at night. after a few weeks, i tried to back up at night. the lights are completely inadequate and they are a safety hazard. i have to get out of the vehicle every few feet and check to make sure there is nothing/no one in my path when backing up at night. i asked the dealer to check/repair the lights. they said this is a common complaint but there is nothing they can do to fix it. it is not safe to back up the vehicle at night because the lights do not illuminate enough to see if someone is in your path. i have asked the manufacturer for help fixing the problem but they said there is nothing they can do. *tr

We have a toyota highlander (2008) which is having safety issues. the passenger seat belt keeps going off. there is nothing in the seat but the bell keeps going off. it doesn't happen all the time but it does it often enough that it could be a safety issue. my second complaint is the window. the windshield keeps chipping when anything hits it. there are several times when i had to replace this window. there could be no other cars around but if something hits it will spider. my third issue is there is a noise that happens when we start the car. its in the engine and we cant find it. i have taken the car into toyota but of course they cant find anything. i have had nothing but expensive issues with this unsafe car. i want to know if there have been any recalls on these issues?

While driving on highway the sunroof exploded and sent glass fragment everywhere. fortunately the shade was pulled closed otherwise glass would have been blown into the driver and passenger compartment at 55 mph. glass was completely distributed throughout the headliner and it had to be removed to ensure glass would not interfere with air bag operation or become a projectile if the air bag actuated. the sunroof is made of tempered glass and not safety glass. when it exploded, the glass was not held captive by the safety film. only a two inch border of glass remained in the sun roof frame. this is a very significant safety oversight. if the sun roof shade had been open, the driver would have been hit with glass and an accident would likely have occurred. *tr
