Engine failure on other Mustang years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2017, 2020.
What this problem usually is
These are the reports nobody wants to file. The engine started knocking or ticking, the oil light came on, and then it seized or had to be replaced. Some owners had the replacement covered under warranty or an extension, and plenty were told they'd pay. Several narrower sheets split this group into knocking, seized engines and rod bearing failure.
What got replaced
Owners who name the part that was replaced mention the engine (26 reports).
Recalls and investigations
No recall on the engine covers the 2019 model year as of Oct 2, 2026.
NHTSA investigations into the engine on the Mustang

What owners paid
6 of the 29 reports quote a price. Each dot is one quote. The middle half runs $3,900 to $11,000.
When it happens
The middle half of failures fell between 26,000 and 56,000 miles, from the 19 reports that gave a mileage.
Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2019 Ford Mustang that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Some 2018-2019 F-150 and Mustang vehicles equipped with a 5.0L engine may exhibit a light to moderate knocking type noise at idle (600-700 RPM) that is sometimes described as a quiet diesel type sound.

Should you keep driving it?
This page can't tell you that. 0 of 29 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. How reports land on this sheet.
