excessive rotor wear?

[Zed 71]

Replaced mine at ~22k due to warping and subsequent shimmy during braking. Upgraded to EBC and this was one of the best mods IMO. I go camping a lot in the mountains and wanted secure brakes with no fade.

The OEM rotors on the NNBS SUVs are complete garbage. If you don't warp them while torquing down your wheels you'll do it under normal driving.
When I replaced mine I went with EBC Sport rotors and Hawk pads in the front, OEM rotors and pads in the rear (didn't realize OEMs were so bad when I replaced those but the rear doesn't do much of the braking anyway). The cost of the EBC rotors and Hawk pads (bought online) was the same as it would have been if I used OEM parts (at slightly over cost since I'm a GM dealer employee).
It was a shock having them warp since I came from a 07 2500HD diesel and I think you'd have to stop a locomotive to wear out the OE rotors on those.

FWIW it seems to be another industry wide issue...over in the Tundra/Sequoia world we warp rotors like crazy over there too. We eat them up on our Charger cop cars well before we ate any up on a crown vic but thats the price u pay to play i guess. they have to cut weight someplace to help the CAFE mandated EPA ratings so i guess rotors would be a place to save some? i dunno. but its getting more and more common with large trucks or big power or large trucks with big power just in normal driving.

It goes into the shop tomorrow for the hitch cover, we'll see what they say about the rotors.

Got a call from the dealer and the rear pads have 2mm left and the fronts have 4mm left. He said the grooves on the rotor are due to the hard brake pads. 20k and the dang brakes are wore out on this car!!? And he says the pads are hard, but wouldn't a hard pad last longer? I know this is a heavy vehicle but her last car lasted 60k before doing the brakes. Of course the rotors are not covered.

Agreed!
Plus mine were nasty rusty at 5000 miles I felt like changing them jsut for that. Bro has 36000 miles on a R/T charger and the rotors look brand new with no grooves or rust.

The dealer is next to useless on this issues. They never admit design issues unless its a safety hazard like the heated washer fluid recall.
