Service bulletin Circular 40S9

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

During strut assembly, an issue may have caused a deformation of the strut mount. If the strut mount is deformed, it can lead to improper torque on one of the bolted connections on the right or left suspension strut mounting. Inspect and, if necessary, replace the right and/or left suspension strut mounting(s).
