One problem related to carrier/rack has been reported for the 2010 GMC Savana. The most recently reported issues are listed below.
I have 5 GMC vehicles 2007 yukon 2010 denali truck and 2011 yukon denali SUV all have cracked dashes. I replaced one, but realized its obviously a manufacturer issue. I am concerned I could cause an issue with the airbag. The rattling has caused issues with my onstar and radio. I have a 2001 1500 with no dash issues and a 2001 Savanah with no issues.
