Service bulletin 122-B8L7J-05

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

Concerns: Connecting links on anti-roll bar on rear axle Information: There is a possibility that the threaded joints securing the connecting links to the anti-roll bar on the rear axle were not tightened to the specified torque on the affected vehicles. This can cause increased play between the connecting link and anti-roll bar over the service life of the vehicle. As a result, noises can occur when driving on uneven road surfaces for example.

122-A7C8T-102018-10-15. Service bulletin. Informatin: Internal tests have shown that the longitudinal and transverse control arms installed on the affected vehicles may be prone to corrosion. The durability of these components cannot therefore be unequivocally guaranteed.
122-A8U3D-052018-05-21. Service bulletin. Condition Loose or Damaged M8 Threaded Inserts Technical Background The protective panel below the engine is actually an integral part of the rear CFRP monocoque. The rear suspension must never be ladened without this panel properly installed and at least the eight M8 fasteners installed and tightened to specification (see Figure 1).
122-E4S9A-042017-10-15. Service bulletin. During hard cornering maneuvers, a rhythmic clicking noise may be emitted from the rear axle hubs. This noise is a non-hazardous, non-destructive characteristic of the vehicle. The root cause is the relative movement of the wheel and brake rotor against the 5 drive pins of wheel hub. This tiny amount of movement produces vibrations that are propagated through the rigid suspension joints and carbon fiber reinforced structure of the vehicle. Improper wheel nut tightening or trace amounts of lubricants, debris and corrosion between the hub, brake rotor and wheel all can facilitate this movement. Procedure: If the clicking sound becomes unacceptable to the customer, repair actions may be attempted that may provide at least a temporary solution. These should be implemented in two successive scopes depending on severity and reoccurrence.
