On january 2, 2019, while driving, the "brake pads worn" light came on in my vehicle. i was on a city street, in motion without my brakes depressed, but rather my foot on the gas driving. i in turn contacted land rover customer service to see if this is a known issue as this light appeared when my vehicle had 13,680 driven miles on it. i was advised at that time to take the vehicle to the dealership for inspection of the brakes. i did as i was told, took the vehicle to the dealership 1.09.2019--their earliest date available. they advised my that my back rotors were rusting, that the left back brake was 2mm and the right was 4mm. they recommended at that time to replace only the left side. when i questioned why they were not wearing equally, the service advisor suggested that perhaps because it was my first time driving an suv--which was not the case and i told him this at that time. i also asked why the rotors were rusting so quickly, he stated that perhaps it was because of the area of the country where we live--i refutted this stating i have owned other suvs by other manufacturers all while living in the same area and did not have this issue. i did not accept their quote and took the vehicle to be repaired elsewhere--of which they too could not explain why the brakes went to quickly on the vehicle and commented to me that this is abnormal. i contacted land rover customer service, they stated they would investigate the issue--they simply called the dealership and nothing more, advising me that the brakes need repaired out of pocket. my concern is that this is a manufacturer defect where the rotors should not typically rust this quickly, the brake pads should not be, as the service advisor stated be "chewed up from the rusting rotors." last, the brakes should not be wearing unevenly on the vehicle.
