Overall Verdict
★★★★★3.4/5
The Wrangler is a lifestyle purchase with a durable body-on-frame chassis and cheap parts. The Grand Cherokee is a nicer daily driver with more complex electronics and powertrains. The Cherokee (KL, 2014–2023) has had documented ZF 9-speed issues.

Do your homework
Models to Research Carefully
Not deal-breakers — but they reward a careful buyer.
Cherokee KL (2014–2023)
The ZF 9-speed automatic had rough shifting complaints early. Multiple software updates and later builds improved behavior. Test drive under varied conditions.
Renegade (2015+)
Small crossover with 1.4T or 2.4L options. The 9-speed automatic has similar considerations to the Cherokee KL.
Grand Cherokee EcoDiesel (2014–2019)
Emissions settlement affected these years. Verify buyback status and any post-settlement updates.
Wrangler 4xe (2021+)
PHEV recall history — battery fire risk led to updates. Verify software has been performed.

Do your homework
Engines to Research Carefully
Not deal-breakers — but they reward a careful buyer.
3.0L EcoDiesel V6
Emissions settlement and EGR cooler concerns. Verify settlement and service.
5.7L HEMI with MDS
Lifter tick — same as RAM. MDS delete is a common preemptive fix.
2.0T (Wrangler JL, Cherokee)
Newer turbo — less long-term data. Direct injection carbon buildup is a future consideration.
