I can second that about the steering wheel jerk from experience of driving a lot of different cars.Steering wheel jerk comes from a bad battery. I already posted about it in another thread. When dealer replaced OEM battery with ACDelco AGM the jerk went away. But I agree, start-stop is annoying and it feels more rough on our Regals vs newer Buicks.
Anyone can try that on a vehicle equipped with EPS and a dead battery. Jump start it and then turn the wheel quickly, you will feel the jerk.
