I bought a 2004 ford focus se in March 2004. After three month, there was some noise coming from the front part of my car whenever I stopped at traffic light, like some vibration, not very loud. I sent the car to the dealership and the noise was gone after they lube the brake. But last week, I heard the noise again, people in the dealership told me there might be some problem with the transmission mount, totally different from what I heard last time.
Any ideas? I didn't expect to have a problem with my car only after such a short time.
