Summary

The 2012 Jeep Wrangler, while a capable and desirable vehicle, has some known issues that potential buyers should be aware of. The most significant concern is the potential for cylinder head failure on the 3.6L engine and TIPM failure that can cause a variety of electrical issues. The “Death Wobble” in the suspension is also a common problem that can be dangerous and costly to fix. Transmission issues, while less frequent, can also be expensive. Overall, while the Wrangler offers a unique driving experience, buyers should be prepared for potential repair costs and carefully inspect any used model before purchase. The TIPM recall should be checked to ensure the vehicle has had the repair completed.
