Multiple owners of the 2014-2017 Chevrolet Silverado and GMC Sierra have noted an odd occurrence. Around 45 MPH, the vehicle will begin to shake the entire vehicle, including the floor boards, seats, bed and cabin.
The AutoGuide goes on to describe the issue as:
Online forums and the National Highway Traffic Safety Administration’s (NHTSA) complaints database are flooded with posts alleging that GM’s full-size SUVs, including the Chevy Tahoe and Suburban, GMC Yukon and Cadillac Escalade, all exhibit the same off-putting traits: unexplainable wind buffeting and vibration. Many of the complaints allege that these problems also affect the Chevy Silverado and GMC Sierra.
GM issued a preliminary information bulletin (PIT) over the issue. Poorly attached roof sheet metal is the main issue that GM looked to fix and instructions for doing so are located in PIT5318B. To perform the fix, technicians have to remove the vehicle’s headliner and inspect the roof bows for proper bonding with the roof sheet metal. If there is an issue, the bonding must be completely redone, which means new panel control vibration material is packed into the roof of all SUVs that have received this fix.
The PIT is accessible here and only covers the 2015 Cadillac Escalade, 2015 Chevrolet Suburban, Tahoe and GMC Yukon.
