When operating the 2021 Ascent, I experience intermittent problems at various shift-points in the CVT and at various RPMs. The transmission seems to shudder and slip between shift-points, and the shuddering sensation is so severe that it transfers up through the steering column and the steering wheel shakes. I have brought the vehicle to my dealership (Kocourek Subaru in Wausau), and they have acknowledged that the shuddering is taking place and even documented it in the 18K service invoice. They ran it through the protocols for NHTSA TSB 10185089, and were not able to achieve fluctuation in the gear ratio. Since the TSB test, the dealership again took the vehicle and has had it for ca. three-weeks, and have tested it, replicated the issues described above, downloaded data, sent data to Subaru of America, replaced some kind of sensor associated with the CVT, and sent additional data to Subaru of America, and are awaiting a response from SOA as to the next steps.

On our first road trip in our new Ascent the windshield cracked. It rapidly spread about 18 inches. We heard no impact, saw no rock - just an ever spreading crack. We called a local Subaru dealer in Lexington, Kentucky who assured us the car was safe to drive home to Savannah. On the trip home we encountered a heavy rainstorm and noticed leakage at the crack. I am filing this after seeing the large number of Subaru owners reporting similar occurrences. We had just experienced another cracked windshield on a 2019 Subaru outback that we had repaired on 11 May 2021! There is something not quite right about this windshield in the Subarus.
