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

Fitment of lower spring seat isolator to front damper assemblies to eliminate scraping noise whilst driving. Movement between the contact areas of the front damper spring seats and road springs can cause a scraping noise whilst driving. If this scraping action is occurring, then it will also cause visible witness marks on the spring seat/spring contact area. To prevent this scraping action on customer vehicles, the isolators already fitted to the upper spring seat, can now also be fitted to the base of the front road springs. As a production running change, lower spring seat isolators will also be fitted from: Emira V6 VIN: SCCLEKAX5PHN10585

- [131\-26017](/bulletins/11034557.md), 2026-07-07, Service bulletin: SUSPENSION. TITLE Availability of Emira service replacement lower front wishbone ball joint dust covers. REASON An unfinished rough edge, on the steering knuckle assemblies \(hub carriers\), can, under full suspension/steering movement, contact the lower wishbone ball joint dust cover, resulting in premature wear or damage to the dust cover. Service level dust covers are now available which prevent the replacement of complete front lower wishbones assemblies and associated labour times for suspension/steering alignment procedures because of split or damaged ball joint dust covers. ACTION If damage to the ball joint dust cover as shown above is seen during an underbody inspection \(such as routine servicing etc\), but the ball joint is still in a serviceable condition, then the rough edge of the steering knuckle casting should be smoothed and the ball joint dust cover replaced.
