As a heads up our power lift gate started not closing the past month or so and finally took it in. The dealer determined the power mechanism of the driver side was failing and is being replaced under warranty as we had purchased the 7yr/125k warranty when we purchased new on 3/2014 and now have 104k on the clock. With that said on closer inspection I do believe if the pivot points where motor/strut meets the body had been kept properly lubricated this could have been prevented. I am sharing as this part costs $425 and most folks probably don't have an extended warranty. I have attached a video showing the pivot points and I do apologize for not shooting it in landscape.
