NHTSA has recalled 27,188 2009 GM models - Cadillac Escalade, Escalade ESV and Escalade EXT; the Chevrolet Avalanche, Colorado, Suburban and Tahoe; and the GMC Canyon, Yukon and Yukon XL. A problem in the fuel system control module, which has a vulcanizing seal that may separate, can allow water to seep into the module and cause a short circuit while driving.
Dealers will install a new fuel system module for free.
