Transmission Gear Slipping Problems of Subaru Ascent

The transmission occasionally slips, resulting in a momentary rise in engine revs and a slight lurch. I assume that this is related to the known transmission issue for earlier Ascents, but mine is not included in the affected VIN number group. Other people traveling in the vehicle with me have noticed the issue and remarked on it, so I am not imagining it! Subaru have not yet diagnosed it but will do so at the next oil change. This behavior has been a feature of the vehicle from new and it has now done about 12,000 miles. The event occurs maybe once a week or so.

The Subaru Ascent was purchased August 2018 (about 7 months ago) and the car currently has about 14,000 miles. The cvt transmission began slipping around March 16th, 2019, causing intermittent vibration and loss of power when accelerating. This would occur at both low and high speeds, and would occur more frequently after the car had been driven for about 15 minutes. At highway speeds, the car would struggle intermittently to maintain speed. Initially the problem was sporadic, but with every day grew more frequent. After being taken to dealership to be evaluated, the dealer reported that while the technician was test driving the vehicle, complete failure of the transmission occurred and the car was no longer drivable. The dealer has ordered a new transmission to replace this failed one. Total time from onset of problem to transmission failure is about 2 weeks with regular daily driving.
