Car Warranty Expiry Checker & End Date Calculator

The car warranty expiry checker works out when a manufacturer’s new-car warranty ends: usually a number of years from the date of first registration or a mileage limit, whichever comes first. Pick a preset or type the terms from your warranty booklet, enter the first registration date from the V5C and, if you like, the current mileage. It does not look up your car: it uses only what you type. The result shows the end date, the days left and, if you enter a mileage limit and a current mileage, the miles left.

Presets checked 3 November 2026. Manufacturers change terms, and parts such as paint, corrosion, the battery or audio can have different cover, so check the booklet or ask a dealer.

How to use the car warranty expiry checker

1. Pick the warranty terms from the list, or choose “Type my own terms” and enter your own. The presets are headline terms, so check them against your booklet.
2. Check the length in years. The tool accepts a whole number from 1 to 15.
3. Check the mileage limit. Leave it empty if the warranty has no mileage limit.
4. Enter the first registration date from box B of the V5C. The tool rejects a date in the future or a date it cannot read.
5. Add the current mileage if you want to see the miles left. Leave it empty if you only need the date.
6. Read the end date and the days left. The warranty ends at whichever comes first, the end date or the mileage limit. If the result says the warranty has ended, the car is no longer covered by that term.

For example, a car first registered on 1 March 2021 with a 7-year, 100,000-mile term runs to about 1 March 2028; the booklet gives the exact last day. At 45,000 miles, the tool shows 55,000 miles left. The tool compares the end date with today’s date, so the days left change each day. If your booklet gives a different length or mileage cap from the preset, choose “Type my own terms” and enter those figures instead.

Warranty end dates and preset terms

How a manufacturer warranty end date is worked out

The end date is the first registration date plus the number of years in the term. If the registration date is 29 February, the end date falls on 28 February in a year without 29 February. A mileage limit works separately: once the mileage reaches the limit, the warranty ends even if the date has not passed. The tool shows the end date and the miles left, and it marks the warranty as ended if either limit has been reached.

Preset terms

Many other brands give 3 years, some with a 60,000-mile limit and some with unlimited miles in all three years. Check your booklet, because the preset list is not a full list of brands.

Choosing the right terms

The preset you pick sets the length and the mileage limit. Type your own terms when your booklet says something different, for example a shorter length or a lower mileage cap. The tool does not check the booklet, so the terms you enter are the terms it uses.

Does the warranty pass to the next owner?

Manufacturer warranties normally stay with the car for the rest of the term; check the booklet for any conditions.

Common mistakes

• Using the purchase date instead of the first registration date. The warranty runs from registration, which is on the V5C.
• Forgetting the mileage limit. A car can reach the limit before the date runs out, which ends the warranty early.
• Assuming all parts are covered for the same length. Paint, corrosion, the battery and audio can have different cover.

Servicing at an independent garage

UK competition law protects this. The Motor Vehicle Agreements Block Exemption Order, in force since 1 June 2023 and overseen by the Competition and Markets Authority (CMA), keeps the rule that a manufacturer must let you use an independent repairer without losing warranty cover. Follow the service schedule, use parts that match the manufacturer’s specification, and keep the receipts.

Frequently asked questions

When does a car warranty start?

Usually on the date of first registration, which is in box B of the V5C.

Which brands have the longest warranties?

Among mainstream brands, Kia (7 years / 100,000 miles), MG (7 years / 80,000 miles) and Hyundai (5 years, unlimited miles) are the best known. Toyota Relax, launched in 2021, can extend cover to 10 years or 100,000 miles if the car is serviced at a Toyota centre.

Are wear items covered?

Usually not. Brake pads, clutches, tyres and wiper blades are normally excluded unless a manufacturing fault caused the failure.

Does the warranty end when the mileage limit is reached?

Yes, if the terms include a mileage limit. The warranty ends at whichever comes first, the end date or the mileage limit, so check the booklet for the exact wording.

What if the registration date is 29 February?

The end date falls on 28 February in a year without 29 February, which is how the tool calculates it.

Does the tool check my warranty with the manufacturer?

No. It works only from the terms, date and mileage you type in. Ask the manufacturer or a dealer to confirm the warranty on your car.
