Steering too tight, wrist and hands get very stressed in short time, keeps pulling to a side, need to put force on steering to stay in lane, very stressful to make turns at all speeds, steering set to low stiffness by dealer, yet very painful, no fix from dealer, says thats how it is since its electronic steering. I see several blogs about the same issue, surprising that there is no remedy. Turbo failed twice before 50K.
