I have 16,000 miles. Had the rotors cut at about 9,000 and they need to be cut or hopefully replaced again now. I have a friend that also had his done twice already. Seems they are very thin, and warp very easily. For example, driving through a puddle when the rotors are hot could damage them, even though they should be able to withstand the quick cooling.

I plan on replacing the rotors with a nice set of slotted ones when the warranty is over. Or, hopefully before then, Chevy will take responsibility for this obvious problem and upgrade us with better rotors.

 

Part of being an SS. From Bob Lutz: "SS vehicles must turn, stop, and go substantially better than the base vehicle." Something they haven't always done in the past.

 

My LT had the same rotor problem. The dealer would only machine them, even though the car had only 28000 miles...too soon for quality rotors to be warped. When the rotors warped again, about 7000 miles later,I replaced them with after-market rotors. I hope they last. If not, I have a great supply of warped rotors to be machined until they're too thin.\ to machine.

 

have had mine turned twice already with less than 30k on the vehicle. Asked the dealer about this problem and he said all they can do is turn them. both times i've noticed a pulse in the brakes when slowing at highway speeds. Turned them and it's gone. I've *****ed about them turning them, but thats all they can do Gm will not let them replace them. I know that this is just going to be an expense i will have to deal with when my warranty is up. My rotors get rusted if i don't drive it for a few days and the humity is high. I've never had the problem before with any other gm car i've owned to i think they (gm) need to recall these rotors.... Is there anything we can do???

 

Try tightening the lug nuts in 3 stages...whatever the torque value for the lugs is should be divided by 3. Tighten the lugs evenly, always going to the opposite lug,up to the first 1/3 setting, then repeat 2 more times until you reach the final factory recommended setting. This MAY solve the "warped rotor"problem. If not, at least the lugs will be properly tightened. I bet most tire shops don't train their people to do this.

 

No issues at all with mine. But I don't wait till the last second to brake like most drivers these days seem to.

I see it a lot with our fleet vehicles, drivers that are hard on brakes go through pads and rotors faster than those they drive like you should

 

We had the rotors cut per the TSB at 16K miles when my wife was still the primary driver on the car. The car is now mine, and has about 24K on it. The rotors are still fine. To the person complaining about rust on a rotor in wet weather, every car I've owned will have the rotors rust in damp weather. Honda,Ford,GM, OEM+aftermarket it doesn't matter. Rotors are steel and they rust.

 

Due do brake vibration we had to have our rotors resurfaced at approx. 25K. It now has 40K and need it again. My wife is hard on brakes but I really think that the rotors are either made poorly or too small for the application. If I was going t keep the car I would upgrade to the larger rotors that are available on the higher end models.

 

Problem, is when you have the rotors cut the material gets thinner. They will warp just as easy. Better off replacing the rotors than having them cut. Autozone sells the rotors for 44.00 each. You already in there just replace them and put on new pads be done with it.

 

Agree, but how well of quality are the Autozone rotors? I was thinking about going this route, but was wanting to hear from someone who has used them. Are they just as prone to warping or is the durability at least a step above OEM?
