The navigation system malfunctions with strange letters and imagery.

- Cary, NC, USA

The sunroof exploded while I was driving at highway speed in high winds. No object or debris struck the vehicle. The sunroof simply exploded, likely from an undetectable defect in the glass and air pressure differential, coupled with torsional or air pressure differential forces caused by the wind. The glass of the sunroof exploded outward, with most of the glass being thrown out and behind the vehicle, and some landing on the sliding sunshade that covers the sunroof, that was closed at the time. The glass clearly shattered outward, as you can see in the images taken immediately afterward, attached.

The collision avoidance system does not work. Has never worked since vehicle was purchased on April 1, 2017.

Was driving and the pre-collision system picked up a car in the left hand turning lane when I was going straight and brought my car to a dead stop. Happened a second time- same trip, different location. No pre-brake or warning, just brought my car to a dead stop when passing a car in a turning lane to my left and there were no vehicles in front of me either time- my car was in motion. 55mph the first time, 45 mph the second. Both times going straight. I took the car to the nearest dealership and they had a safety inspector from Toyota come out and run tests- they gave me my car back and said I would have the results of the test within 30 days. My concern is why this happened in the first place and what was done to ensure it won't happen again. I bought the car on 2/4/2017.

Lane deviation warning is not audible when veering either right or left at speeds over 32 miles per hour as stated in the owners manual. Our 2015 Toyota rav 4 lane deviation warning was loud and clear.
