While driving the car at 70 mph on a freeway it suddenly veered to the right. quick action on my part kept the car from running off the road onto the shoulder. i took the car to the local subaru dealer at the first available appointment. they inspected the car and found the on-board computer showed an indication of a steering angle sensor fault. they kept the car overnight and road tested it but because they could to duplicate the problem they made no repairs to the vehicle. at a minimum, i feel they should have replaced the steering angle sensor and asked them to do so and they refused. i consider this car unsafe to drive.
