Wanted tailgate noise fixed while under warrantee, but was put off by dealer to wait for recall fix. Recall fix did not solve problem of loud noises when using power tailgate. After about 2 years I received recall letter from gm and dealer did recall work. However , the noise problem still exists and dealer tells me I will need to pay $725 to fix part # 23142258 because it is not covered under long awaited recall repair. I called gm customer assistance center and they cannot authorize repair either. I beleive the recall module by not working correctly caused the gear failure. That's why I believe gm should fix the tailgate. All this happened over a 2 year period. While car was in warrenty and now out of warranty. Since gm had to fix all 2011 Acadia's the process took too long and damaged the vehicle. I received my recall letter in November 2015 , years after announcement was made.
