My Toyota Camry has been making funny noises for the last couple of months. It's sometimes a "groaning" kind of sound and other times a high pitched whine. It occurs some times when I'm braking, and when I'm at a standstill (e.g. at the lights) with my foot on the brakes and even when I'm driving along. The noises make me nervous and I always get weird looks from other drivers.
3 months ago, I had my rear brakes replaced when I complained of the noise(s). Last week, I sent it for servicing at a Toyota dealership and my front brakes & rotors were replaced. I was told the noise came from my tires. I found that explanation puzzling. I am still getting those noises which seem to be coming more frequently and louder.
Does anyone have any clue what could be causing these sounds and if it's indeed the tires, why would they be making those noises?
