Official summary
Some vehicles may exhibit a knocking noise from the rear coil spring and/or the vehicle body sits lower in the rear. These symptoms may be caused by a broken rear coil spring at its lower side. This is caused by corrosion from dust between the rear coil spring and the spring sheet, resulting in a broken rear coil spring. To eliminate this concern, the shape of the rear coil spring has been modified.

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.
