Not sure if anyone else has noticed this, but when slow moving with almost full lock on there's a sort of bumping sound from the front wheels? Its fine on normal roads feels tight and planted but tight slow sharp turns throw this noise and feedback through the steering wheel. I borrowed a courtesy car which showed similar characteristics also.
That's not abnormal for any car actually. It only happens at full lock. It's caused by the front tires not being pointed in the correct direction for the arc they're on. There's nothing that can be done about it. It's a rather lengthy and involved explanation as to all the in's and out's about how the steering geometry works and why.
You could go to an independent alignment and insure that the wheels are aligned correctly. They will insure that the alignment is correct while going straight. The sharper you turn the wheel, the more incorrect the wheels will be. That's not usually a problem. At 'racing' speed, the inside tire is barely touching the ground and it doesn't matter what direction it points. At normal speeds, you're not turning sharp enough for this to be an issue. It isn't until parking lot speeds that the wheels get turned so sharp they can hop.
Some cars have the steering lock adjusted so the tires can't turn so sharp that they start hopping. This isn't the other steering lock that prevents a thief from steering your car without a key.
Some cars have been designed in such a way that the wheels won't get off-arc enough to hop. But, they drive like crap at speed in the canyons. It's a trade off. I prefer the better handling at speed and seldom experience the parking lot hop anyway. My 4C has this hop. Some call it the racer's hop. lol
