## Your Warranty Explained

Every new Jeep, RAM, Dodge, or Chrysler from Castle CDJR of Naperville comes with manufacturer coverage that protects your investment. Understanding what's included helps you plan maintenance and avoid surprises.

### Typical Coverage

**Bumper-to-bumper:** Usually 3 years or 36,000 miles; covers most non-wear parts and defects.

**Powertrain:** Usually 5 years or 60,000 miles; protects engine, transmission, and drivetrain.

**Rust perforation:** Often 5 years or 60,000 miles; covers corrosion from manufacturing defects (not road salt damage).

### What's Not Covered

Wear items (brakes, pads, wipers), routine maintenance, accidents, misuse, and aftermarket modifications typically aren't included.
