Example complaints

Steering: “When I make a left turn, my wheels and steering wheel get out of sync and this causes the car to temporarily become hard to steer. At this point, the car doesn't respond to normal steering gestures. It feels as if the car is going to veer out of the lane and it doesn't respond for me to correct it from veering off unless I turn the steering wheel completely towards the left hand traffic which is very unusual and very scary. When to correct itself, the car jerks itself as the steering wheel and tires re-allign themselves. …”
