Original document

Condition
The customer complains of clicking noises from the wheels while maneuvering at slow speeds. The clicking noises
can be traced back to the contact points between the carbon fiber aeroblade inserts and the 21” alloy wheel.

Figure 1 - Sound File

Technical Background
The clicking noises can be attributed to one or multiple of the following causes:
1.
Improper labelling of the parts at the supplier
2.
Improper packaging of the parts at the supplier
3.
Dimensional inaccuracies resulting in the parts being out of tolerance
Countermeasures for causes (1) and (2) have been implemented in production since December 2020. However,
spare parts should still be checked upon arrival to ensure that they are properly labelled and packed. Improperly
labelled and packed parts may still exist in the current stock.
Updated parts to address cause (3) are expected to be available by January 2022.
