There are two driver assistance features, lane departure warming and side collision warning. Neither of them seem to work on my car even though I have them activated in the settings menu. Lane departure is suppose to work when you are not in autopilot mode and you are going over 45 mph and you don't have your turn signal on. When you move across the marked pavement the stearing wheel us suppose to vibrate (not to be confuse with going across rumble strips). I have tried this on multiple occasions with no luck. Side collision warning is suppose to be an audible and visual warming if there is a car detected in your blindspot or close to the side of your car. This feature also doesn't work. I have accidentally almost hit a car in my blind spot with no warning. While there is a visual indication if there is a car close to the left side of my car there is never an indication if there is a car close to the right side and never an audible in any case. I thought it may be because my car was built early in January but according to my service center it works comparitable to the new cars coming from Fremont. If this is how these two features are suppose to work this function is useless. Have others tried these functions.
