2022 Subaru Outback Suspension Problems

On 03Feb24, immediately following a 4-wheel alignment of my 2022 Subaru Outback Limited, my vehicle’s suspension feels unstable over patched potholes or rough/broken pavement. I can best describe the condition as similar to the movements felt while hydroplaning but it does it on dry road. It jerks side to side; 3 or 4 times; in rapid succession; just enough to command the driver’s full attention. The condition happens periodically at highway speeds. I’m afraid my vehicle might lose grip and crash. I have brought my vehicle in twice to my local Subaru dealership for inspection. The mechanics have been able to witness the condition. A few measures were taken to remedy the condition including, vehicle re-alignment, installation of one shock absorber on the rear suspension to no avail. The mechanic report, issued 10Apr24, states the condition may be due to the brand new tires installed on 19Feb24. However, this assessment is inconclusive and requires expensive trail and error tied to buying a new set of tires. The condition started on the OEM tires and still occurs with the new set of tires. The condition began 03Feb24, immediately following it’s first ever 4-wheel alignment at the dealership. I have been trying to get this fixed since then. The condition persists as of the date of this writing. On 16Apr24, I submitted a formal complaint through Subaru of America web form.
