Official summary
The customer complains of hearing a creaking or knocking noise from the front of the vehicle when the vehicle is twisted, such as when being driven into or out of a driveway. The customer may describe the location of the noise source as the front suspension area. This type of noise may be caused by the contact between the hood height adjustment stop buffers and the lock carrier. While noises originating from the front of the vehicle may have a number of causes, the repair described below will eliminate this possible cause.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
