Condition
Some customers may comment that the driver's power bucket seatback moves forward about 25 to 38 mm (1 to 1-1/2 in) during moderate to heavy
braking.
Cause
To reduce the amount of vibration being transmitted through the seatback, a spring was incorporated into the driver's bucket seat recliner assembly. This
spring pre-loads the seatback to assist in absorbing and reducing vibrations being transmitted through the seatback and into the headrests when the
vehicle is in motion. The forward movement of the seatback during moderate to heavy braking is the result of the pre-loading.
Correction
Advise customers that bucket seatback movement of 25 to 38 mm (1 to 1-1/2 in) during moderate to heavy braking is considered normal. However, for
those customers who desire to have the seatback movement addressed, replace the driver's bucket seatback recliner assembly and attaching bolts. This
recliner assembly does not have the pre-load spring used to reduce vibrations. Prior to installation, customers should be advised that there may be some
vibration transmitted through the seatback and into the headrest with this recliner assembly.
