One problem related to transmission gear slipping has been reported for the 2020 Subaru Ascent. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 Subaru Ascent based on all problems reported for the 2020 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.
