The easiest way to check your car warranty is to find your VIN, record your current mileage, and contact the vehicle manufacturer or an authorized dealership. You can also review your warranty documents, owner’s manual, and purchase paperwork to confirm your coverage and expiration date.
How to Check Your Car Warranty Step by Step
Follow these simple steps:
1. Find Your VIN
Your VIN is a unique 17-character number. You can usually find it:
- On the driver’s-side dashboard
- Inside the driver’s-side door
- On your registration or insurance card
- On your title or purchase documents
2. Check Your Mileage
Many warranties have both time and mileage limits. Record your current odometer reading before checking your coverage.
3. Contact the Manufacturer or Dealer
Give an authorized dealership your VIN and mileage. They can usually check the vehicle’s warranty status and explain which coverage is still active.
Can You Check a Car Warranty by VIN?
A VIN can be used to identify your vehicle and help the manufacturer or an authorized dealer locate its warranty records. However, the VIN itself does not confirm that a factory warranty is currently active.
To verify your actual warranty status, provide the VIN along with your current mileage and, when available, the vehicle’s in-service date. The manufacturer or an authorized dealer can confirm the applicable warranty coverage, expiration date, mileage limits, and other conditions.
Can You Check a Car Warranty Online?
Some manufacturers offer online owner portals that show warranty information. Availability varies by brand. If the online information is unavailable or incomplete, contact the manufacturer or an authorized dealer.
How Do You Check Your Warranty Expiration Date?
Check your warranty documents or ask the manufacturer or dealer. Warranty coverage typically has a specific time and mileage limit, and the applicable terms determine when coverage ends.
What Types of Car Warranties Should You Check?
| Warranty Type | What It Generally Covers |
| Bumper-to-Bumper | Many vehicle components, subject to exclusions |
| Powertrain | Engine, transmission, drivetrain and related components |
| Emissions | Certain emissions-related components |
| Corrosion | Certain rust-through damage |
| Extended Warranty/Service Contract | Additional coverage under a separate contract |
Coverage varies by manufacturer and contract, so always check the specific terms.
How Do You Know If Your Car Is Still Under Warranty?
Check your:
- VIN
- Current mileage
- Warranty documents
- Vehicle’s in-service date
- Manufacturer or dealer records
Then confirm the active coverage, expiration date, mileage limit, and exclusions.
How to Check a Warranty on a Used Car
Use the VIN and current mileage to ask the manufacturer or dealer about remaining factory coverage. If the vehicle is certified pre-owned, also review the CPO warranty documents. Check whether the warranty is transferable and when it expires.
How to Check an Extended Warranty
If you purchased an extended warranty or vehicle service contract, review the contract for:
- Coverage period
- Mileage limit
- Covered components
- Exclusions
- Deductible
- Claims process
An extended warranty or service contract is separate from the manufacturer’s original warranty.
What If You Cannot Find Your Warranty Documents?
Contact the vehicle manufacturer or an authorized dealer with your VIN and mileage. For an extended warranty or service contract, check your purchase paperwork, emails, finance documents, or contact the contract provider.
What If Your Factory Warranty Has Expired?
First, confirm that the factory warranty has actually ended based on its time and mileage limits. Then check whether you have a CPO warranty, extended warranty, or vehicle service contract. If no coverage remains, you can compare available vehicle protection options based on your vehicle’s eligibility.
What Information Do You Need to Check a Car Warranty?
| Information | Why It Matters |
| VIN | Identifies your vehicle |
| Current mileage | Determines mileage-based coverage |
| In-service date | Helps determine warranty expiration |
| Year, make and model | Identifies the vehicle |
| Warranty documents | Shows coverage terms |
| Service contract | Confirms additional protection |
What Should You Ask the Dealer?
Ask:
- Is my factory warranty still active?
- What is the exact expiration date?
- What is the mileage limit?
- Which warranty types are active?
- Is the warranty transferable?
- What components are covered?
- Are there any applicable exclusions or limitations?
Does Maintenance Affect Your Warranty?
Keep your maintenance records and follow the manufacturer’s recommended maintenance schedule. Warranty terms can require proof of proper maintenance, so keep receipts and service records.
