mac, If it's designated-capable of "Variable assist" , sounds like it's not "controlled" properly BY the controller (module here ,usually). Find out if any "re-program/update " can be done . Definitely test others-even if you HAVE to 'pretend' at a nearby Dealership to do comparisons.Remote possibility is changing ,slightly, the rack pre-load. Tires , I had Dunlop SP5000's on a car doing exactly what your talking,it was a CONSTANT chore keeping in lane , to correct - it would "overshoot" and I'd have to go back & forth CONTINUOUSLY!

Impossible to relax or even lookout for directions & landmarks ahead.Then I put on Goodyear F1 GSD3 Eagles - rode on rails. Tires = a crapshoot though.I sympathize,and I think "electronic steerig" sucks compared to "old school" hydraulic.My sister- Camry was "her car

" and looking for a third one , we both drove test on a "off the hauler- 3mi odo" at Toyota lot. It was all over the road (new tires? maybe) but salesman bragged electric steer.
