What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
I was driving on a free way during rush hour when I heard an explosion. I pulled over and discovered the moon roof to the car had shattered and created a vertical protrusion from the window. The temperature that afternoon was 109 and I had driven from an altitude of 7,000 feet to 1,200 feet. There was also a significant drop in temperature from the higher elevation. A highway patrol officer stopped to offer assistance and noted he had worked in dealership and the problem was common.
I was driving between 55-65 MPH on a two lane highway when the panoramic sunroof spontaneously exploded. The majority of glass blew up and out of the car, but small pieces were falling back into the car. The temperature outside was approximately 66 degrees. Traffic was moving well, but heavy.
The 2 rear seat belts (not the middle one) became detached at the connection point at the top of the seat. The belts appear to have been torn or severed as if they were cut at the point where they are attached.
The automatic liftgate would close all of a sudden when I'm reaching for item(s) deep in the cargo area. I was told by the dealer that since my feet are under the hands-free/ kick sensor for the automatic lift gate that that would activate it. However, the liftgate would also open or close when I'm not under the sensor such as filling up for gas or putting the car cover on. Fortunately, this only happens when the car is stationary.
