Sun visor failure - visor is no longer staying put and is a safety hazard as it falls into drivers line of vision randomly.

Tl* the contact owns a 2007 nissan titan. the contact stated that the driver side sun visor would continuously drop down, obstructing the contacts view of the roadway. the vehicle was not inspected by a dealer or repaired. the failure mileage was 57,000.

This is my 2nd nissan titan in less than 2 years! i traded in a 2005 with less than 20,000 miles because of 3 full tire set replacements and new brakes at 6,000 miles and problems that the dealer stated are currently fixed in the new 2007 models. my new 2007 at 1200 miles dealer replaced defective rims with a new set of defective rims that are a after market plastic hubcap glued to the steel rim which is clicking and popping while in motion and after 15 minutes driving when i park they still pop and click until they completely cool down which is about 30 minutes later. i also have the drivers side window go down by itself and stop exactly at 3 inches after i attempted to close it, my ac does not cool at all and often does not come on even when my gps screen says it is set on high and running i have to pull over turn off truck then restart truck to get ac to come on. dealer says they cannot find the problem even though there is a tsb on it that i gave them! dealer said window problem is due to georgia heat, it is doing what it is suppose to do but my other 3 windows don't have a problem! my rims they stated that they want to put more glue a tsb tech to fix the problem! that is not a repair that is a band aid that will not hold with the heat tires put off! as of now i will never ever purchase any nissan ever again and i will be buying new rims for my truck and nissan consumer affairs has not helped at all what so ever only tell me to do the tsb glue repair and even though i paid 1800.00 extra for chrome rim package they will not refund or purchase new rims at all so i am on my own. *tr
