Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2011 model year Cadillac Escalade, Escalade ESV,
Escalade EXT; Chevrolet Avalanche, Colorado, Express, Silverado, Suburban, Tahoe; and GMC Canyon, Savana, Sierra, Yukon, and Yukon XL
vehicles. Some of these vehicles have a condition in which the rear axle cross pin was not manufactured to specification. The pin may have been
improperly heat treated and could fracture and become displaced within the rear axle. If this were to occur, the driver may hear a banging noise coming
from the axle. If the pin shifts out of position, it could create an interference condition and cause the rear axle to lock. The driver may not be able to
maintain directional control of the vehicle and a crash could occur without prior warning.
Correction
Dealers are to inspect and, if necessary, install a new rear axle cross pin.
Vehicles Involved
Involved are certain 2011 model year Cadillac Escalade, Escalade ESV, Escalade EXT; Chevrolet Avalanche, Colorado, Express, Silverado, Suburban,
Tahoe; and GMC Canyon, Savana, Sierra, Yukon, and Yukon XL vehicles.
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Required Field Actions section in the Global Warranty system.
Not all vehicles within the above breakpoints may be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address
information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to
export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration
data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you
