This vehicle has the pro-pilot assist which keeps the vehicle between the lines centered. it is an auto steer. we have had numerous times where the steering will go from line to line, it will cross the line put you on shoulder, cross the center or even move you into another lane with traffic in it. we have complained to dealership, they took it for a week said they found nothing wrong. within 24 miles of getting it back it was doing it again. they said unless the engine light is on ( for engine code) they will do nothing. this is a feature used mostly on highway at highway speeds. this issue is most dangerous, at highway speeds if it does this could cause a multi vehicle collision resulting in serious injuries or death. i cannot pinpoint certain dates as it has happened enough where my wife will not use it.
Vehicle malfunctions randomly while driving or at a stop light and all of the driver assist/safety assist functions show error messages. it also happens while on the highway. i don't know if the car will stop on the highway.
