Are there known issues with the brakes/rotors on Honda Ridgelines?

What is your question?

I purchased a new 2012 Honda Ridgeline and I am the only driver. It has just under 30,000 miles and I was due for oil change so I also had the 30k service done. Before the service I started feeling a slight vibration when braking; like the front rotors might be slightly warped. The Honda dealer service dept. checked and told me the rotors were warped and could be turned. The brake pads were still in very good condition so there wasn't a safety issue. I asked how the rotors could be warped so soon and was told they see this happen even at less mileage and is usually due to driving habits. Also said it is caused by excessive heat. Most of the 30k miles were highway and country roads. Only recently have I started driving to a new job where I'm in "aggressive" driving conditions where I might be going 70mph and then need to slow down quickly. A couple of times I've needed to break hard; but not lock your brakes hard. So I guess I'm wondering if just a few hard braking incidents could cause my brakes to warp? I'm also curious if others have seen this with their Ridgelines or other Honda models. It just seems to me that the rotors shouldn't warp this quickly and if there is a problem with excessive heat, is there another type of brake pad that will not produce as much heat in mostly "normal" driving conditions. Thanks!
