The guy I spoke to at the DOT didn't tell me we could file via the DOT Auto Safely Hotline. But we can. Here's the link.

It takes about five minutes. You'll need your VIN #.

Here's what I wrote:

I own a 2000 Vehicross by Isuzu. I bought it new four years ago and have only 26,000 miles on it. A few months ago the power window mechanism on the driver's side had to be replaced due to a failure of the track alignment.

It cost me $800 to fix.

Upon coming in contact with an organization of several hundred Vehicross enthusiasts I discovered that this type of window failure is epidemic with this model car. Some of the owners have had multiple failures -- i.e., the windows have been fixed only to fail again, sometimes three or four times.

At the moment I have 27,000 miles on the car and now the passenger's side window is beginning to fail.

I have contacted Isuzu but they deny there is a problem. On the other hand I understand there are official documents by Isuzu that do recognize this problem.

Since there was a limited distribution of this particular model car -- somewhere in the area of 4000 plus over a four year period -- it appears the window failure rate is a high percentage of that total number. I would ask that the department investigate this problem, including investigation of the internal Isuzu document mentioned above.

If there is, as it appears, a design flaw in the window mechanism, then there are hundreds of Vehicross owners who have improperly been charged to repair it, sometimes multiple times.

I'm going to follow up by sending them a copy of the poll and comments from this site several weeks ago.
