Official summary

Complaint Bulging and contact of the rear spoiler when hatch is opened (picture 1-1). When opening the rear hatch, the rear spoiler rests at the roof edge, which can result in damage to the rear spoiler and roof if the hatch is forcefully opened when the rear spoiler is bulged over (picture 1-2). Cause In the event of higher outside temperatures, the spoiler of the rear-end door thermally expands and may be above the roof by several millimeters. When opening the rear hatch when the rear spoiler is in a bulged condition, this can result in a collision between the rear spoiler and the roof edge.

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.
