Extended service coverage picks up where your factory warranty ends, protecting you from unexpected repair costs.

**What's Covered**

Typical extended plans cover major components-engine, transmission, electrical, suspension, and air conditioning-for a set period or mileage limit. You choose your deductible; lower deductibles cost more upfront but mean less out-of-pocket per repair.

**How It Works**

When you need a covered repair, you visit an authorized Chevrolet service center (like ours at Castle Chevrolet of Villa Park). You pay your deductible; your plan covers the rest. There's no claim paperwork-it's seamless.

**What's Not Covered**

Wear items (brakes, wipers, oil changes) and routine maintenance aren't included. Cosmetic damage and damage from accidents or misuse aren't covered either.

**Is It Worth It?**

It depends on your mileage, how long you keep the car, and your comfort with repair risk. Our service and finance teams can break down options and costs. Call (630) 279-5200 to explore what fits your needs.
