So I noticed today that when braking hard, the front driver side feels like there is a slight clunk or it’s having a harder time braking. Don’t get me wrong, I still stop on a dime and there is no screeching sound. I kept trying to duplicate the problem by accelerating to about 20-30 mph then braking with medium/hard pressure (not stomping hard) but applying decent pressure. It would happen about 3/5 times. Not sure if I’m just overthinking it.
The dealership (not Lexus) I picked the car up from replaced both front rotors/pads (only about 300 miles on them since replaced). But I guess they ran out of the same brand of rotor so the front left driver side (rusted looking one) is a different brand rotor than the front right. I don’t know if that is what is causing the issue or not.

Those don't look like the same rotor, that is for sure. I find it odd that it already looks that rusted. It is normal for it to look rusted, but that's a huge difference between the two. Do you know for certain it was replaced?
My two cents - go straight back to the dealer. A clunk while braking could be anything - at worst, something is not installed correctly.

Yeah I thought it was odd it was so rusted as well. I asked both the sales manager and the salesman who I talked to and they confirmed it was replaced. I asked for paperwork on top of that and they provided it, showing it was indeed replaced. Apparently their supplier ran out of the same brand of rotor so they used two different brands, one has that rubber coating to prevent rusting and the other doesn’t.
I also brought the car to my local Lexus dealership and had them do a full inspection/oil change because I don’t know what type of oil the other dealership put in and Lexus said everything looks good and confirmed that both rotors were brand new.
Again it’s not really a clunking noise per se, and it doesn’t happen consistently. It just feels like that front left driver side rotor sucks lol. Braking under normal or every day use it feels completely fine. But under harder brake usage, it feels weird but the issue is inconsistent. I can’t replicate it every time. So I’m thinking it’s just the brand of rotor is garbage. I wanted to use it until my next brake change but I just might swap out that front driver rotor/pads and keep the other one. Instead of replacing both.
