I drive a 2005 3500 Chevy express van that has a driver's side mirror that moves while driving at highway speeds. I took the van to the local dealer who stated they ordered and replaced the mirror. After picking up the van I noticed it was no different. I took it back and they told me there was nothing they could do. I feel this is a safety issue because at highway speeds it is difficult to see vehicles coming up beside me. I would like help in getting the problem solved.

I am concerned about the field of vision provided by the mirrors on my van. I have owned three full sized vans since 1995, and have never had this problem before. My concern is with the style and size of the exterior mirrors. Most full size van manufacturers have horizontal mirrors, but Chevy opted for a vertical that has cut down on the peripheral vision field of the driver. This concerns me greatly as I perceive it to be a safety hazard especially when trying to merge onto a freeway, and keeping abreast of approaching traffic from the rear of the van. The reduced peripheral vision has caused a number of near miss collisions. I have had the van since August 2005, and have tried numerous mirror configurations to improve the situation to no avail. The mirrors as designed do not provide the peripheral vision that I had with my 2000 Dodge van that had horizontal mirrors. I have even tried the suggested mirror adjustment techniques on mygmlink.com to no avail. I have expressed my concerns to the manufacture, but they continue to refer me to their customer service department even when I've asked to speak to someone in engineering or design.
