I have the same problem. I have replaced them twice in 30,000 miles. I have a 2006 and I was hoping that someone here might have an answer because it appears as though mine are starting to go again.

I had this problem. 23k miles the dealer resurfaced the rotors.. it helped but I know it will be back, probably sooner because they're even thinner now. The best thing to do would be just flat out replace them with GOOD aftermarket models... not stock GM.. or you'll get the same thing.

YES, we have had to trim the rotors twice and the third time (only 5000 miles) had to replace them. We are hoping this may be a fix. Very distrubing with only 73,000 miles on the car. I have never had this problem with any other cars we have owned

Yes we had the same problem as well. We had them machined twice and then had to replace rotors at only 60000km. Seems to be a very common problem.

We had the same problem with my wifes HHR. We took it to Midas and they replaced the front rotors and adjusted the back brakes. Haven't had a problem since. That was about 50,000 miles ago.

I'm in the same boat - I'm on my second turning at 66K and figure I'm going to have to replace them soon. It seems to be a HUGE problem with this car - CHEVY are you listening??

I am beginning a list of people that have had the ongoing problem of bad rotors on their HHR. I am replacing the rotors for a third time and GM said that they have never heard of this problem. The dealer states that he has never heard of this problem. What kind of a cover-up has happened at Government Motors. If you have had this problem and are interested in being involved in this proposal for law suit, please provide me with your VIN number and all contact information. I will be posting this at other HHR blogs as well. You can respond to me here or at

yes i have!!!!! omg.... when i first bought my car which is an '06, i took it right back into the dealership because of the rotars. They rotated them and now i am having the same damn problem

Jon Romero

If people stop driving this like a race car than maybe rotor warpage wouldn't occur...just sayin.

Maddie Riesland

fyi to the last guy who posted a comment. hey honey first i am a girl so i am not testosterone driven, and secondly it is lowered so anyone who has a lowered car knows that you can't drive a low baby like a race car because you got to pay attention for the dips and pot holes in the road so you don't fuck anything up, and my rotors are still warped, so kinda like suzuki sidekicks have the genetic flaw of having bad window regulators and the tranny's always seem to go out at about 120,000 miles, these cars have bad rotors.

Here is the problem – according to the service manager at my local Chevy dealership – the HHR was built on the same platform as the Cobalt. The HHR weighs around 1200 pounds MORE than the Cobalt – and shares the same brakes. Chevy denies the problem – but it’s obvious looking at this board that I’m not the only person that has had THREE brake jobs – the third including NEW rotors.

You go girl!!


I am going into my 4th visit for the rotars. I am at 80,000 miles now.

Deborah Polk

OMG!! That's just not right! I had to break down and invest in newer, heavier rotars - set me back about $125 but it drives like new (just hit 80K miles too). It's ashame Chevy hasn't picked up on this problem - the service manager at the dealership was clueless. Well, sorry about the problems - hope you get your wagon running soon! Take care - D.


My '08 Panel has 68800mls and I am on the 8th set of rotors! This car has always been serviced at the same dealer who insists there is nothing wrong! I have contacted GM online with absolutly no help at all an dthey have assigned a" district specialist" her name is Cindi Pakiv . Cindi doesnt even own a car , has never opened the hood on a car and is niether in the district( shes in Mumbay India) or a specialist in anything but getting rid of the blinking lights on her phone panel. Good luck , the only time GM will care about U.S. consumers is when they need there mis managed butts bailed out again. Do yourself a favor and lemon law the piece of crap before the dealer runs the mileage too high for a lemonlaw claim like they did with me, they are trained to do that.

yes i have and now i cant do anything about it i changed them and now i dont have a problem


I am on my 3rd set of rotors, 2nd were pos slotted EBC brakes and matching pads. Don't buy those! only lasted about 3000 miles, warped worse than the stock ones. Then i change to drilled and slotted Stop Rite Brakes and pads, I have about 15000 on them and need to get them turned. I always figured our problem is that we live in the mountains and my brake just get way too hot while driving down the mountain. Sounds to be a common problem.
