Too many people are to short sighted. As far as not being willing to pay for good quality, that's NUTS.
Look at all the people on these threads complaining about warped rotors.
I don't think they would baulk at paying $15 or so more per rotor on a New car purchase in order to save them all the grief and large premature brake repair bills for the life of their car.
Why is GM now recommending that I replace my warped factory rotors with New slotted rotors through there parts dept ????? HMMMM.....
Are they finally getting tired of turning these for free even though they only agreed to do it for me one time per Van. A Company in Denial......
It's a "sore subject with customers" that bought what the thought was a NEW CAR and not some used Junker with botched brakes.
The experts are the ones that should sort this out, not the hard working people that don't have time or knowledge to deal with it.

Please don't take my comments personal ...Unless your a GM dealer.

 

knock on wood...I have never had any rotor problems yet 06 cobalt ss 24K beat the hell out of the car...went through stock pad and half way through a set of hawk hps..and no problems with my hhr.

 

Neither GM or Chevrolet are recommending this. Your DEALER is. See comment below.

I have no problem with your comments. But neither I nor my owner is GM and we don't make policy for GM, we only abide by their decisions. We are a privately owned business that is franchised with GM.

 

Drilling makes for less metal, but also increases surface area for cooling, like the finned heads on a 2 stroke motor.

I though rotors were made of cast iron.

 

While I find this commentary VERY interesting and agree with SOME....disagree with others.....I don't believe the intent of the thread is to discuss rotors/brake issues.

I think offering suggestions as requested is a better "fit".

I would like to see this DEBATE continue with a thread dedicated to THAT topic, however.

 

Thanks Snoopy, my original reply (post #2) was in response to the OP's request. I wasn't looking to debate or hear other users opinions. I was hoping it would get asked and an answer would be given by Troy Clark.

Now I will sit back and see if the question was asked and what his reply was.

 

There might be a delay on your question's answer because Troy Clarke is actually a business-ops VP as opposed to an engineer. However, the wife has some contacts who know others within the engineering sector, who might have an answer for you. We'll see what happens - if he's unable to give an answer, she knows folks who will be able to.

 

ask him if I can borrow 100 bucks..

I just don't buy this survey and would like to know a lot more about it. Is someone really telling me that Lexus is one of the most troublesome cars on the road? Saab? Volvo? Hundai is the best, most reliable car on the road? Really..........

I too do not think GM is a bad company, but I don't understand this at all.

 

The thread went in the directon of Rotors due to my original question as to reliability of rotors in GM products. While it did go off on a tangent, I too would like to see it reintroduced into a new thread, especially the discussion of slotted/drilled vs. standard rotors. Anyone?
