Rearview System Braking problems of the 2023 Toyota Highlander

There are two problems with our 2023 Toyota Highlander. 1) we only have 25k miles on our vehicle and the brake rotors became warped, to the point of causing severe chatter while downhill braking. Toyota stated that the warranty does not cover brakes. My argument was that the brake rotors should not be failing at 25k miles! they then stated that they would inspect the rotors and resurface them, if necessary. They did find that they needed to resurface the rotors. My contention is that this will be a recurring issue, especially since there is even less metal on the rotors now. I believe the original rotors are faulty to have failed prematurely. 2) we had a receiver hitch installed by a third party, which caused the kick sensor for the back hatch to be inoperable. This is expected and no big deal to us. However, when we put the bike rack in the receiver hitch, the backup warning sensors engage the brakes and cause the vehicle to not back up. The only way to back up with the bike rack on is to disable the backup sensors! now we have lost that backup safety feature! the backup sensors see the bike rack and engage the brakes. Additionally, this issue also caused all other sensors to malfunction by stating that the sensors were dirty and needed cleaning, with the backup sensor engaged. Toyota inspected the vehicle multiple times and finally reached the conclusion that there is no fix for the sensors to allow our bike rack to be installed. Toyota sells this vehicle with the option of having a hitch and bike rack installed, yet their safety sensors don’t allow this to happen. Now, we are unable to use the bike rack, unless we disable the sensors. The safety features we paid for are now useless!.
