I have been getting the "Service Front Park Assist" message for the past couple of days. I hear the chime and look down and I see the message. I have also noticed the lights below the off/on buttons are coming on and going off by themselves. I checked the sensors and they are clean. I am going to take it to the dealer tomorrow and see whats going on. I also made an appointment to do the recall on the cruise control, but thats not until the 23rd. I don't know if I can go without the Park Assist for that long, I love that feature. Any ideas what would cause the problem with them?
