Official summary
Supersedes Technical Service Bulletin Group 40 number 10-10 dated September 10, 2010. Light cracking or rubbing noises when steering. The noise emanates from the front suspension strut mounting. The complaint occurs most often when the vehicle is maneuvered at slow speeds (e.g., parking) or when the steering wheel is turned while the vehicle is not moving. The noise is not caused by extreme load on only one suspension strut (e.g., slowly driving uphill while turning the steering wheel).

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.
