What owners wrote

“Refused to fix the issue because the OBD reader did not provide any codes OBD reader is not sending any signals, but there is power I called Sam’s Ford to send a service to fix the recall but told me they will not fix the issues because no codes were being provided And the check engine light is active”

“Check engine light on. Code is p0301 for multiple cylinder misfires. At startup I can hear coolant sloshing around and white exhaust. Coolant is leaking into cylinder 1. The Ford dealer says it needs a new engine. 2019 ford mustang ecoboost at 55k miles.”

“Coolant intrusion into cylinder 2 at 26,000 miles. Was told by mechanic this is due to thin cylinder wall design between cylinder 2 and 3. And the thin coolant channel cut between them. A new engine block manufactured after 2020 was recommended because the engine design was changed to fix this issue. My warranty expired 4 months prior so I had to fix myself.”

Should you keep driving it?

This page can't tell you that. 0 of 38 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
