The Jeep Wrangler is iconic, but the years to avoid are well documented. The 2012 3.6L Pentastar had the cylinder-head rocker-arm recall. The 2018-2019 JL launch produced the 'Death Wobble' class action. Here is the year-by-year breakdown.
Avoid: 2012 (first-year Pentastar rocker arm), 2018-2019 JL (first-year defects), 2021 2.0T (oil pan recall)
Buy: 2015-2017 JK 3.6L Pentastar (post-rocker-arm fix)
Scores 1-10 based on NHTSA complaint volume, severity of reported issues, recall history, and class-action exposure. Higher is better.

The 2012 (Pentastar rocker arm recall) and 2018 (JL Death Wobble, frame weld recall) are the most-cited worst years.
A violent steering oscillation that starts when a front wheel hits a bump at 45+ mph. Causes include worn track bar, ball joints, steering damper, or improper lift. The 2018-2020 JL has the most complaints.
After the 2012 rocker arm recall, the Pentastar is generally reliable. 2014+ Pentastars are considered the sorted version.
2018-2019 had the most launch issues (Death Wobble, frame welds, touchscreen). 2022+ JLs are much more sorted.
Be cautious of 2021 models (oil pan recall). Verify recall completion. The 2.0T can be a good engine when properly maintained.
2015-2017 JK Unlimited with the 3.6L Pentastar is the consensus pick. Last of the simpler architecture before the JL touchscreen-heavy redesign.
