New vehicles from Jeep, RAM, Dodge, and Chrysler include a manufacturer warranty covering defects in materials and workmanship-typically three years or 36,000 miles for basic coverage, with longer terms for powertrain (engine, transmission). Warranty is non-transferable or limited if transferred, depending on the manufacturer.

### What's covered
Warranty covers unexpected failures: engine problems, transmission issues, electrical defects, and factory recalls. It doesn't cover maintenance (oil changes, filters), wear items (brake pads, tires), or damage from accidents or misuse. Regular scheduled maintenance is your responsibility.

### Used and certified vehicles
Used vehicles sold without certification have limited or no warranty. Certified pre-owned (CPO) vehicles include extended manufacturer-backed warranties-typically five years or 60,000 miles-giving you peace of mind on a recent-model used car.

### Making the most of it
Keep all service records and maintenance up to date; it protects your warranty. Use authorized dealers for service to ensure warranty compliance. Know your coverage terms and what's excluded.
