I've had my MSP for about 3 weeks and I am already experiencing problems. I've had a pretty bad steering wheels shake and that was fixed due to wheel balancing. I am experiencing engine hesitation and my dealership is looking in to a reflash. Also, my rear bumper attachment is coming loose near the exhaust. And just this afternoon I began to experience a loud whistle noise similar to a siren at around 4 - 5k rpms. I understand that a turbo will be louder, but this is the first time I've heard it in 3 weeks. I've had 3 Mazdas now(MP3, P5, MSP) and never any problems till now. What gives? What exactly is this high pitched whistle? I thought it was a cop behind me!
