After a small pebble hit my windshield, an extremely large crack appeared and grew within moments of the impact. It has spiderwebbed all over the windshield and obstructed the vehicle's eyesight cameras. A second impact within a few days has done the same right in front of the driver's seat. The spiderwebbing of the cracks was near immediate and grew faster than 3 inches per minute.
On average about twice per month, the touch screen will lock up. This causes the entire system to crash turning off cruise control, emergency braking, lane departure, lane keep assist, and almost every other "Smart" function of the vehicle. There is no specific action that causes this, it is purely random. The "lock-up" can last anywhere from 30 seconds to several minutes. The dash notifications telling you that all of the assistance features have turned off don't come on until the system has rebooted, even though they stopped functioning at the same time the "lock-up" started. On a typical day, there is a significant delay in controlling these features via the touch screen. Minor issues where the assistance features are delayed by several seconds have happened often, but this does not result in a complete system reboot. The best way I can describe it is as if the vehicle is controlled by a computer running windows vista with so many viruses it can barely function. Even just adjusting the electric seats or stereo volume can have up to a 30-second delay from user input to the system response. I have noticed that during these delays, the assistance features (like lane keep and collision warning) are also delayed.
