Automatic Stability Control (asc) problems of the 2017 Nissan Maxima

The car is becomes unstable and difficult to control when going over bumps, even at moderate speeds (20+ mph). When going over bumps, there is a loud thump / clunk / bang from the rear suspension - and then the rear of the car looses traction/stability. Nissan must be aware of a design issue issue as it has issued a TSB trying to solve the inferior bushings it chose for the rear suspension - service bulletin ntb17-107. However this does not solve the instability problem. I find myself driving at half the legal speeds to keep the car stable - the need to slow down for each bump is creating a road hazard. Driving on the same roads with my other cars at much higher speeds (road legal speeds), I do not experience anything like that. The stability control function does not seem to help and it lights up frequently when driving on bumpy roads. I found myself veering of the road several times because of the difficulty to control the car. This must be a terrible and dangerous design flaw. In roads that I can drive the legal speed in a Hyundai sonana or Toyota 4runner (45 - 65mph) I sometimes need to cut speed in half when driving the Nissan Maxima sr just to keep the car stable on the road.
