2015 GMC Yukon Denali - 32k miles (6.2L + 8spd). I don't normally do highway speed but noticed yesterday that I had a slight pedal vibration when doing so and it only seems to happen at 60+ mph. My daily drive is under 40mph and no vibrations there. I'm assuming its likely a rear rotor since I don't feel it in the steering wheel.
I looked back on my records and it appears front brakes were at 7mm a year ago and rear at 4mm. Both in the "green" according to dealer. I'm not sure if its an eyeball check and they just mark good or if they actually measure but it was 10k miles ago and a year so I likely need new pads.
All this to say, with this life and mileage is anyone seeing pad life and possibly rotor life exhausted so quickly? This is a heavy vehicle and the 6.2L gets it up to speed quickly and it does seem to take a lot more to stop it(always this way so I don't think its the vacuum recall).
If anyone is getting a 4 wheel brake job at the dealer, what has it run you? Mine is running a special for $139 per axle for pads and $189 per axle for rotors but I'm hoping if it is a warped rotor I only need 1 pair.
Also noticed this on the front passenger rotor. Is that defined of a groove normal? To the touch it doesn't feel grooved.
Tire inflation is normal.
Just the other day I started to notice a vibration/rattle noise coming from the front passenger side around 70mph. It almost sounds like the windshield, or what you would expect something rattling against glass to sound like. I can’t pinpoint where it’s coming from, but’s somewhere within the vicinity of the passenger side dash/windshield/headliner area. Sounds more like it’s around the headliner area.
It it mostly only seems to happen at higher speeds (70+mph) although today I did just today hear it at 60mph for the first time. My guess is maybe the the windshield is leaking some air since it happens at higher speeds??? Because going over bumps doesn’t seem to have any negative or positive impact on the noise.
Anyone else have any issue like this, or any guess as to what it might be?

Anyone know what this noise is? It's very intermittent. Seems to do it most often between 40 and 50 MPH cruising with maybe a slight up hill. Never does it on coast or heavy acceleration. Very hard to tell where it's coming from.
