In the summer of 2011, I had Harmon AutoGlass install a new windshield in my vehicle. After installation, my family & I noticed a 'whistling, rushing' sound as we drove down the freeway. This had never been present before the new windshield was installed. We then turned off any air flow, closed all windows tight, put towels over the dashboard air vents, and drove again down the freeway. The sound was still there - exactly as before, I took a match and, after lighting it, put it up by the top inside of the windshield, and put the match out. The smoke from the match immediately blew away from the top of the windshield, proving this was the location of the noise - and demonstrating the lack of a proper seal around the windshield. I contacted Harmon AutoGlass, and they came out and 're-sealed' the windshield. Again, the same noise was present, but a little more muted. When the colder weather hit the Twin Cities, the sound became very loud again.
I again contacted Harmon AutoGlass and, after explaining that there was still not a proper seal around the windshield and offering to bring the vehicle to their Roseville, MN location; I made an appointment for 3:00 pm, Tuesday, 12/20/2011. I arrived at Harmon AutoGlass at 2:56 pm, and was told, "We are very busy today; you need to wait 10 minutes and I can get your car in". By 3:34 pm, we were still waiting, and were told, "Well, I can't control how long things take".
I explained I had made a 3:00 pm appt. for a reason. Harmon made no attempt to do anything to move the process along. I was appalled at the ridiculously poor customer service. I left, as I had to pick up my daughter and would have been (very?) late if I had waited for Harmon to get things figured out.
That evening I e-mailed Harmon AutoGlass from their site, and asked them how they were going to resolve this. I also told them studies have shown a windshield is an integral part of a vehicle's safety, especially in a roll-over accident. I gave them the opportunity to correct things, and they chose to not respond - more than a week later. Apparently they either are not aware of, or do not care about, a little thing we call the internet. I mean, they didn't even respond!
Stay away from Harmon AutoGlass!
