Engine failure on other Wrangler 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: 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2025, 2026.
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 (44 reports).
Recalls and investigations
No recall on the engine covers the 2024 model year as of Oct 2, 2026.

When it happens

Should you keep driving it?
This page can't tell you that. 0 of 44 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.
