NHTSA Complaint #11548410 — 2019 SUBARU IMPREZA

I brought my car into my family mechanic to get an inspection after I noticed severe shaking when breaking and a burnt rubber smell. They determined the left front caliper was hanging and needed to be replaced- the caliper is covered under my warranty, so I brought my car into the dealership - service department at dealership was UNABLE to detect the issue for weeks until I gave them detailed instructions on how to find the issue, once they agreed the caliper needed to be replaced, the part was backordered until late august - I got my car back after they changed the caliper and the issue is still happening after long drives- dealership is still UNALBE to detect the issue - I am being told after market brakes are the issue
