NHTSA Complaint #11603947 — 2019 ACURA TLX

This car exhibits rumbling when goinin to a decreasing downward motion as if its trying to change gear but cant. coming home from a doctors appointment last month it was raining an coming up to the top of a very small hill and just as i hit the top at the point the shocks start to lift up I almost lost control. This is not the first time its happened. It usually happens in a decelerating turn. but I have tried to get appointments with Huntsville and nashvile dealerships. Hunstville had my appointment i waited for for 4 months and it was around june the 14th and they told me not to come in they were out of parts. So they had parts but ran out!
