ronna,,,best of luck. I have taken my 2011 LT sedan w/(5) speed on a similar trip with similar miles when I left. Far point was DeAnza Springs, Calif in the high Mojave dessert with stops in Las Vegas and Phoenix, etc. We came back thru the Rockies and I 70 into K.C. Not a single problem. Several years later a pass side wheel bearing failed so I had both replaced. Now that you are back, how was your trip? Good to know you bought your 2011 new. I bought mine in Nov., 2013 with 16.6K miles as a repo. Love that car for all these years!
