Since last NOV 2021, I have had this Ascent into the shop several times due to a 'chirping' or 'speaking' sound that comes from the underside of the middle o/t vehicle. I have come to find out through the service department that the primary differential has a batch of defective parts, and the entire differential needs to be rebuilt (21 parts total are being replaced). It has taken about 3 months to get parts in. The squeak was an annoyance. HOWEVER the situation got SIGNIFICANTLY worse when the wheels would not synchronize when turning - which should be unheard of because there are supposed to be sophisticated traction controls and such in place to prevent that very condition.

The manufacturer has known about this at least since December 2021. Their solution is to reprogram the transmission control unit. Waiting nine months or more for a reprogram seems excessive to me.

On or around May 20, 2022, I was driving on a highway. I took an exit ramp to merge onto another highway. I accelerated and merged in front of a bus and was headed towards a toll plaza when I felt something and heard something. I took my foot off of the accelerator. My car stayed revving at 4500 RPMs with my foot off of the accelerator. I slammed my foot into the accelerator two times and the accelerator released so I could slow down for the toll plaza. I am concerned that my accelerator is going to stick again causing my car to break and be involved in a serious accident. My safety, my family's safety and others are at risk. The Subaru dealer has had the vehicle for multiple weeks and cannot recreate the issue. I was advised that the Subaru field technician inspected the vehicle and reset the programming for the torque converter. There is an open recall on the vehicle for a transmission issue with no fix yet available. There have been no warning lamps or any other messages. My car is available for inspection upon request.
