Driving home from work in the snow on Friday, I thought the steering felt a bit loose.My wife went out for a haircut, said she was going really slowly round a roundabout & couldn't steer, so ended up going up the curb.She got home so I went out in the car & at first, couldn't turn out the drive. After going about 100 yards I turned round & came back. This happened when I was trying to turn round on the drive.I can't believe bumping up a curb would cause this especially when the wheel & tyre are fine.What do people think happened?I've read online about loads of control arm failures?Tesla are picking it up in the morning...
