Engine rattle on other Sonata 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, 2018, 2019, 2020, 2021, 2022, 2023, 2024.
What this problem usually is
Owners in this group hear something before anything breaks. Most describe a ticking or tapping at idle, a rattle that's worse on a cold start and fades as the engine warms, or a noise that comes and goes over weeks. Some report the check engine light following a while later. It's the early-warning end of the engine complaints, and the reports that end in a named part are useful to anyone hearing the same sound.
What got replaced
Owners who name the part that was replaced mention the engine (3 reports).
Recalls and investigations

Should you keep driving it?
This page can't tell you that. 0 of 48 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.
