Service bulletin Dealer Letter -

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

On a limited number of Audi Q5 vehicles manufactured within a specific period, the specification for the front bolted connection on the cross brace was not correctly documented. It is possible that the connections may have not been tightened to the correct torque specification.
