NHTSA Complaint #11497766 — 2019 FORD FIESTA

Catastrophic Engine Failure due to the manufacturer's recommendation and use of conventional motor oils in the form of Synthetic Blend Motor Oil or Super Premium Motor Oil, a specification WSS-M2C945-B1 , from the 2019 Ford Fiesta Owner Manual. It leaves the driver and occupants stranded in the middle of the road with an inoperable vehicle. Being a small 4 cylinder engine the engine is high revving and produces sludge. Whereas if the manufacturer recommended Full Synthetic oil as the car parts store do as part of the oils usable for that specific model. There would have been no engine failure as occurred with my vehicle on 11/22/2022. No sludge would form in the engine. Because synthetic oil is proven not produce any sludge in an engine. I believe a recall should result in the manufacturer recommending full synthetic in the owner manual and engine oil be replaced by dealer service to full synthetic as well as engine work be done due to damage from conventional oil.
