2012 Buick Enclave
Documentation from General Motors (PDF) indicates that 2011 Buick Enclave, Chevrolet Traverse and GMC Acadia crossover SUVs involved in the recall were built from May 27, 2011 through June 1, 2011. The dates of manufacture for the 2012 models affected in the recall are February 15, 2011 through December 1, 2011 (Chevrolet Traverse); February 16, 2011 through December 1, 2011 (GMC Acadia), and February 17, 2011 through December 1, 2011 (Buick Enclave).
2011 GMC Acadia Denali
At issue is that snow or ice buildup on either the windshield or the wiper restricts wiper arm movement. This may lead to the wiper arm loosening and the wiper to become inoperative.
The potential consequence of this condition is a loss of driver visibility, which increases the risk of a crash.
According to GM, a routine analysis of windshield wiper warranty claims in November 2011 identified loose wiper arm nuts as the predominant cause of the claims. GM contacted the supplier and subsequent wiper arm strip-out tests resulted in the fix of increasing the wiper arm nut fastening torque. This change was implemented effective November 30, 2011.
What General Motors will do
General Motors will notify owners of affected vehicles, instructing them to bring them to an authorized GM dealer. The dealer will then tighten wiper arm nuts at no charge. The General Motors safety recall, No. 12036, is expected to begin on or about April 16, 2012.
