Consumer Description

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.
