The AWD transfer clutch is always engaged to some degree when in D or R. When the transmission (in this case CVT) is in a relatively low gear, and the throttle is advanced significantly to accelerate, the pressure on the clutch plates is increased to proactively reduce the propensity for wheel slip (because of the high torque being applied to the wheels). When the clutch pressure is raised, the clutch plates are not as free to slip. Slip is needed when turning, so it’s quite possible that when making a tight turn and trying to accelerate rapidly at the same time, there could be symptoms of torque bind in the drive train until the car speeds up and/or the throttle is backed off so that the pressure on the clutch is reduced.
Have you checked for the symptoms by driving in a tight circle without applying any significant throttle?
How long have you had the car, and when did this symptom first appear in that time?
Is this your first Subaru and perhaps first experience with Subaru AWD?
Not intending to downplay the concern; just want to make sure we aren’t overlooking small details that could be significant.
That said, I vaguely recall seeing similar posts here in the years after the introduction of the CVT. I think there might have been mention of a reprogramming of the TCU to reduce this effect, but I could be wrong. Perhaps some searching of the forums here would be helpful, or someone who has had the same experience will be able to provide more information.
