Loud Engine Noise problems of the 2005 Mazda Tribute

Big loud noise, car started to shake, speed and nearly lost control.

The contact owns a 2005 Mazda Tribute. While driving at 45 mph, an abnormal noise emitted from the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 75,000.

When accelerating greater than 30 miles per hour the car is so loud you can't hear the radio and its too loud for my son the dealer says there is nothing wrong. I just purchased this car (used) on Monday Jan 21,08 I have been calling the madza dealership they keep telling me to wait someone will get back to me. I took the car back in for service to have the sound re-evaluated the serviceman at Mazda dealership said there was nothing he could do because it was raining and that it may be causing the loud noise. What should I do? it is a 2005 Mazda Tribute.
