PRELIMINARY INFORMATION
Subject: Front Seat Lateral Movement and/or Click Type Noise While Driving
Models: 2015 Cadillac Escalade Models
2015 Chevrolet Silverado, Suburban, Tahoe
2015 GMC Sierra, Yukon Models
Condition/Concern
Some customers may comment that the driver and/or passenger seat lower cushion exhibits excessive lateral seat movement combined with a clunk type feeling, or generates a click type noise. This condition occurs when the seat is occupied and the vehicle is being driven on roads with multiple curves or during low speed maneuvers.
This condition may be caused by movement between the seat pan front pivot points and the seat frame pivot bar.
The plastic attachment points may “stick” then “slip” creating the condition. There may also be excessive clearance between the power seat vertical adjuster actuator and the attachment point on the seat frame.
Recommendation/Instructions
Use the following steps to lubricate the front seat pan pivot points, add a lateral retainer to the outboard pivot, and install a shim clip between the power seat vertical adjuster actuator and the seat frame (if required) to the affected seat(s):
