Overheating 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
Most owners in this group notice the coolant before they notice the heat: a reservoir that keeps dropping, a sweet smell, or a bright puddle under the front of the car. Across the vehicles on this site, about four in five of these complaints mention coolant, a leak or a puddle, and roughly two in five mention the temperature gauge or overheating.
What got replaced
Owners who name the part that was replaced mention the head gasket (8 reports), the water pump (3 reports) and the coolant hose or reservoir (3 reports).
Recalls and investigations
One recall on the engine covers the 2016 model year. A recall on the same system isn't always the same failure, so read the defect text.
A hose may separate from the engine oil cooler tube assembly causing an oil leak.

What owners wrote
“My cars head gasket blew at only 45,000 miles. Replaced my a local well known mechanic for around $3500.00. Now my car at 96,000 miles has blown the head gasket again. I believe the car needs a whole new block. I have seen several lawsuits regarding this and just would love my car running again. This is NOT cheap to fix for me.”

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.
