APPLICABLE MODEL(S)NINS

DESCRIPTION
Some vehicles may exhibit a condition where the hood vibrates when driving at speeds of 110 Km/h (68 mph) or
more.
The amount of sealant used to fill in the space between the inner frame and outer panel at the bottom area of
the hood is insufficient. If the sealant detaches (as shown below on the left), it may cause the hood to vibrate.
The amount of sealant has been increased during vehicle production and the preload force of the cowl grill seal
has been increased to eliminate the concern .
