## NHTSA's summary

When the vehicle is driven between 35 mph and 75 mph, a noise can be heard in the front of the vehicle. The customer may say that the noise is coming from the steering column area, and may describe the sound as buzzing, humming, whistling, whining, grinding, howling, and/or droning. The best way to understand the complaint is to discuss it with the customer. Faulty wheel bearing\(s\) may cause the noise.
