I took the vehicle to the lexus dealer when purchase. i told the repair person that there was a noise/roaring coming from the front of the vehicle and i was told that it was the suspension not to worry about it. for this inspection i paid over $300.00. now the noise is back and it is much louder and it is constant.from 45mph and higher.the noise occurs when i am driving straight and when i turn to the right.when turning to the left the noise stops. i sound like the noise is coming from the steering column mechanism. the vehicle has been well maintained.please note that this my complaint. *tr
