XPS 13 trackpad problems

I've had my XPS 13 9360 for just about 2 months and the problems with the track pad are frustrating beyond belief.  I have made every possible combination of modifications to the controls suggested at various websites (with the exception of driver changes) yet problems both intermittent and constant continue at about the same rate. 

I have been a user of Dell Laptops with trackpads for at least 15 years. without any problems. I can use other trackpads without any issues (i.e. I don't have zombie fingers)

My problems include:

1) no response at all

2) erratic and slowing of pointer movement

3) pointer jumps randomly (when using Chrome most often to  zoom controls in address bar)

4) pointer drifts 

I currently have all gestures and pointer accuracy options OFF

I am using Window 10 Pro Ver. 1709 Build  16299.19 with all current updates installed.  (I have Dell auto update and installed all Dell updates)
