I have had this new car for 10 months. Since last month, when i start the car, the rear traffic alerts light comes on on the dashboard and a warning message comes up saying that the rear traffic alert is not working. Then i turn off the car, open and close the driver's door, and start the car again. This happens every now and then. There is no problem with the car or the sensor. I searched the internet and youtube and found that there are some people who have the same problem as mine. I hope this can be fixed.
