Known issues

High

Battery fire recall: 2020-2024 Wrangler 4xe and 2022-2024 Grand Cherokee 4xe were recalled (NHTSA 24V-091 and follow-ups) for HV battery defects causing fires while parked. Stellantis advised owners to park outdoors and not charge until repair. Multiple firmware and module-replacement remedies have been issued.

Low

Charging behavior under low temperatures has been refined via firmware; early 4xe vehicles failed to start charging on Level 2 in cold conditions.

Low

Real-world all-electric range falls short of EPA estimates in cold weather and at highway speeds, similar to all PHEVs. Hybrid mode reverts cleanly when pack depletes.

How this pack ages (industry context)

Industry fleet aggregates: 2.3% average annual capacity loss across 22,700 EVs / 21 models (Geotab, 2026), and 95% range retention at 5 years on average across 30,000+ vehicles (Recurrent, 2026).

OEM warranty floor on this pack: 10 yr / 100k mi to 70% capacity.

Public per-pack degradation curves are not available for most models. Individual results vary materially with climate, charging behavior, and DC fast-charge frequency.
