My year-old 2006 Matrix starts to vibrate quite loudly when stopped at a light. I can often feel the vibration in the steering wheel and the brake pedal. It's been in to the dealer twice. They replaced an engine mount the first time - no change. Second time they made me drive the car and point out the noise. The technician acknowledged the sound and then declared "that's just the normal engine sound." But I am skeptical that Toyota would decide it's "normal" for the car to vibrate as loudly as this.
Any ideas? I see people have had similar issues when accelerating, but this is the opposite - only when the car is stopped while in drive.
Thanks, Nick Beem
