Driver's side visor will no longer reliably stay up, so the visor sometimes falls down suddenly and blocks my view. When it does stay up, it only stays up part way.

The front window defroster and heater controller potentiometer assembly is defective. Ice build-up on the front window is known to impair a driver's visibility and cause an accident. The nut on my temperature controller was several turns loose! the original multi-stranded wires soldered to the temp-controller potentiometer were rigid because they were too well tinned with solder and broke from vibration fatigue; due to the loose nut on the temp-controller potentiometer shaft. Toyota or sumitomo (vendor) should cover this under an extended warranty due to the loose nuts (poor workmanship)! the problem is well documented with photos at "www.devalcourt.com/2010/03/fixing-2004-Toyota-highlander-ac-and-heat-issue/#idc-cover". over 385 people have left comments there; several other websites document the same problem.

The sun visor in my 2006 Toyota Highlander hybrid droops down from the ceiling on the driver's side. Apparently this is a common problem and you have received numerous complaints about this, yet Toyota has done nothing to remedy this problem.
