2014-2015 Chevrolet Silverado & GMC Sierra Shakes, aka The Chevy Shake
GM engineers can’t seem to pinpoint the cause of a systemic 'shaking' in vehicles riding on GM’s K2XX platform, such as the Chevrolet Silverado and GMC Sierra. Owners have aptly titled the issue "The Chevy Shake"
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.
PIT PIT5451A was also released and says it "This Preliminary Information communication provides information to the technician about vehicles that have a vibration at highway speed. Technician will need to replace the wheel for a rolled lip of aluminum in the hub opening." That covers the following vehicles:
- 2011, 2014 CHEVROLET SILVERADO 1500
- 2011-2016 CHEVROLET SILVERADO 2500
- 2013 CHEVROLET SILVERADO 3500
- 2014 GMC SIERRA 1500
- 2011-2016 GMC SIERRA 2500
- 2011-2013, 2015-2016 GMC SIERRA DENALI
