Design Problem by rbowen1063
Feb 23, 2006 (4:04 am)
I recently discovered that while driving at different speeds in my HHR, when you roll down the rear windows, you get a very loud (unbearable) noise and wind vibration inside the car. The faster you go the worst it gets. I confirmed this with another HHR owner. They have the same problem and complained to the dealer, who tried the "eye brow" wind deflectors. They did not solve the problem. They have a sun roof (I don't), which reduces the problem somewhat, when opened. If you haven't experienced this problem, try opening your rear windows (while driving, naturally) and see what happens?

The air buffeting is far from unique with the HHR, it happens on many many vehicles. Its due to the way air moves around (and into) the vehicle. Best solution is to crack front windows enough to eliminate the effect. Sorta feels like whole car is vibrating and/or brain rattling around via your ears

I concur; you'll find that problem in many automobiles. It is NOT a defect.

I realize there is buffeting on several cars. I will research it some more. I have a Lexus that I will try it out on and we'll see. But, today I took the HHR out and at 45 mph I opened one back window and the buffeting on the ears and a siren-like sound (no, it was a cop behind me)were not tolerable, even cracking the front window. I usually don't drive with the windows open, but this problem was brought to my attention by another HHR owner, so I tried it. I was quite surprised at the intensity. That's all I am trying to relate. I think it's more noticeable on the HHR, that's all.

Guess I owe you guys an apology. I drove my wife's ES 330 today and the same noises occur when you open the back windows. So, I have concluded that problem must exist on many of today's cars. I have been driving vans for the last several years and of course, the back windows don't go down, just the rear window vents will open. I still think the auto industry could design something better to solve the buffeting/noise problem, other than driving with the windows closed.

rear quarter damage update by geemac
Mar 02, 2006 (4:50 pm)
My panels are getting worse by the day. The GM help line arranged a meeting between myself and my dealer rep (which I could have done myself) but refused any help in fixing the problem. My dealer rep was very nice but also refused to help,first offering to install boards for $685 and then referring me to the district service rep. A follow up call to the GM help line indicated that the district service rep has the final call on any repairs. I am waiting for a call from the rep to meet to discuss the problem. I still think GM owes me -- and all HHR owners -- runing boards to remedy the design defect. I wouldn't recommend that anyone purchase one without the boards.

I can back up geemac's issue with the rear corners. 5000 miles and my doors and rocker are silver on my Orange HHR.
