NHTSA Complaint #11512680 — 2018 HONDA ACCORD

When the engine is shut down, there is a squeak (have not been able to pinpoint the source). However, prior history on the vehicle considered, wanted to make a record. The vehicle has always had a burning smell to it and, at one point, a dealer's mechanic did replace the head gasket, claiming that was the source of the burning smell. However, the burning smell still persists and I've been wondering if something more serious is going on (as one mechanic did say, there is a possibility of the turbo burning oil due to some defect). Hence, the squeak is suspicious due to that.
