On
some 2008-2010 Escalade, Escalade EXT, Escalade ESV, Avalanche, Silverado,
Suburban, Tahoe, Sierra, Sierra Denali, Yukon, Yukon Denali, Yukon XL, and
Yukon Denali XL models, a buzz or rattle type noise during light acceleration
around 1200-1700 RPM may be heard. The noise may sound like it is coming from
behind the instrument panel.
The
buzz or rattle type noise may be caused by the fuel line bracket, above the
transmission, contacting the floor pan.
Reposition
the fuel line bracket down away from the floor pan.
