Various noises, such as humming, vibration, and/or rattling are heard coming from under the vehicle or from near
the center console area. The noises may appear in the following circumstances:
• When the vehicle is driven at highway speeds.
• During hard acceleration when RPMs are high.
• During deceleration from 40 mph.
• During acceleration from a stop.
Technical Background
While these types of noises could be attributed to a number of components in the vehicle, misaligned front
exhaust hangers may be a contributing factor.
