## NHTSA's summary

Center intake\-air distributor Information: This is to inform you of a voluntary Workshop Campaign on the above\-mentioned vehicles. An intake\-air distributor, on which the shaft for guiding the resonance flap does notmeet the required specifications, may have been installed on the affected vehicles. As a result, the shaftmay break and broken pieces may get into the intake duct and end up in the combustion chambers. This can cause loud noises. It can also result in mechanical damage if the engine is not stopped in time.
