A car that arrives with a problem can raise two separate questions: whether you can cancel a qualifying online sale within a short period, and whether the car fails the contract's quality or description requirements. The answers depend on the seller, the way the contract was made, the car's condition and the dates.
This guide is for a consumer in England who bought a used car from a trader. An online listing, home delivery or a payment taken through a website does not by itself prove that the legal seller was a trader or that the agreement is a distance contract. Start by collecting the order, invoice and messages so you can identify the route before sending a final demand.
First identify the seller and the contract
Find the full legal name and address of the business named on the order, invoice, finance paperwork and payment record. A website, marketplace, delivery company, showroom and seller may be different entities. Save the listing and any description of the car or included features. If the seller says it was a private sale, preserve evidence of how the car was advertised and whether the seller regularly sells vehicles. Do not assume a trader relationship from one advert alone.
Next, write a timeline: when you first contacted the seller, what you agreed, when any deposit was paid, when the seller accepted the order, when the car was delivered and when the fault was noticed. Record whether you visited, viewed or test-drove the car before the contract was concluded, and whether any part of the final agreement was made in person.
The Consumer Contracts Regulations, regulation 5 define a distance contract as one concluded between a trader and consumer under an organised distance sales or service-provision scheme, without their simultaneous physical presence and with only distance communications used up to and including conclusion. The consumer's order and seller's acceptance are important. An online advert followed by an in-person agreement may not meet this definition.
Check the separate 14-day cancellation route
If the contract was a qualifying distance sale, regulation 29 allows cancellation without giving a reason during the cancellation period. For a sales contract, regulation 30 usually sets that period at 14 days after the day the car comes into your physical possession. If the trader did not provide required cancellation information, regulation 31 can extend the period. Check what information and cancellation instructions the seller sent before relying on an extension.
To use the right, tell the trader clearly that you are cancelling under the distance-contract right. Under regulation 32, a model cancellation form is optional; another clear statement is allowed. Send it through a channel that preserves the date, wording and delivery or read receipt. Do not confuse asking for a repair or reporting a sensor fault with clearly cancelling the contract.
Cancellation does not mean that any use is irrelevant. The Regulations can allow a deduction where handling reduced the car's value beyond what was needed to establish its nature, characteristics and functioning. A car may need to be driven to assess how it works, but the line depends on facts and the seller's information. Keep mileage, condition, keys and documents recorded; do not assume either a full refund or an unlimited use deduction.
If the car was not sold under a qualifying distance contract
The distance-cancellation route is distinct from statutory remedies for goods that do not conform. Under Consumer Rights Act 2015 section 9, goods supplied to a consumer must be of satisfactory quality, assessed in context including description, price and relevant circumstances. A feature shown or promised in the agreed description may matter. A fault report is not itself proof that the car failed the contract; age, mileage, price, wear, condition and cause can all be relevant.
Where a trader-to-consumer contract is covered by the Act, the short-term right to reject is subject to section 22 and is generally 30 days after the statutory start conditions have been met. The date may depend on transfer of ownership, delivery and any required trader action. If the car was delivered recently, check the exact dates rather than estimating from when you first noticed the fault.
After the short-term period, section 23 can provide a repair or replacement. A consumer may have a right to a price reduction or final rejection under section 24 if its conditions are met, including where a repair or replacement fails, is unavailable, or is not completed within a reasonable time and without significant inconvenience. Do not assume that one minor issue automatically entitles you to reject a car. Equally, do not assume that a seller can insist on a repair in every situation.
The Act also has a motor-vehicle-specific point about final rejection. A refund may be reduced for use, and the general restriction on making a use deduction during the first six months has an exception for motor vehicles. That exception does not create an entitlement to reject, prove the car is faulty or determine a fair deduction. It affects the refund calculation only if the consumer has the relevant final right to reject.
For a private sale, the Consumer Rights Act trader standards described above may not apply in the same way. The contract description and other rules may still matter. Confirm who sold the car before relying on trader remedies.
Make a practical evidence file
Keep copies of:
- the advert, vehicle description, price, seller identity and any messages about the sensor system;
- the order confirmation, contract, invoice, deposit and balance payment records;
- delivery date, mileage at handover, photographs and any delivery condition form;
- a dated video or report showing what the parking sensors do and do not do;
- messages asking the seller to respond, arrange an inspection or confirm a remedy; and
- any cancellation information and distance-sale terms the trader provided.
Avoid altering the car or paying for a repair before checking what the seller will do, unless an immediate safety issue requires action. Do not drive a vehicle that appears unsafe. If you obtain a mechanic's report, ask for the observed fault, diagnostic steps and likely cause to be separated from the mechanic's legal opinion.
Write to the seller with one clear request
Use the seller's legal name and address from the purchase documents. State when you ordered and received the car, when you noticed the fault, what the advert or contract said and what you want the seller to do. If using the 14-day cancellation route, clearly say you are cancelling the distance contract. If you are reporting non-conformity under the Consumer Rights Act, identify the relevant fault and the remedy requested. Do not mix a cancellation notice and a repair request in wording that leaves your intended route unclear.
Ask the seller to confirm a safe inspection or collection plan, who will bear any return costs under the route you are using, and how it proposes to handle the outstanding payment or refund. If there is an unpaid balance, do not assume that withholding it is risk-free. Check the payment schedule, finance agreement, any acceptance terms and the seller's response with a qualified adviser before changing payment or possession arrangements.
If the business does not respond, preserve the unanswered message and use the complaint route in the contract. Depending on the seller, payment method and type of transaction, another complaint or dispute process may be available. Do not promise yourself that a bank or card provider will refund the purchase; ask the provider what process, if any, applies to the exact transaction.

Before escalating
Check whether the seller is a trader, whether the deal was concluded at a distance, the date the cancellation or short-term rejection period began, and whether the fault matches the car's agreed description. Keep the car's mileage and condition records, write one route-specific notice and request an inspection or collection plan. If the car is financed, the seller disputes the trader status, the fault may affect safety, or a substantial balance is due, seek advice before taking an irreversible step.
Next step
Put the contract, seller identity, dates, fault evidence and payment records in one file. Then decide whether you are giving a distance-contract cancellation notice or asking for a Consumer Rights Act remedy. A professional can review the exact documents and explain how the rules apply to that transaction.
Questions about a used car bought online
Does an online car advert always mean I have 14 days to cancel?
No. The Consumer Contracts Regulations define a distance contract by how the trader and consumer concluded it. An online advert or delivery on its own does not establish that the contract was made under an organised distance sales scheme using distance communication through conclusion. Check the order, conversations, any visit and when the seller accepted the deal.
How long is the online cancellation period for a car?
For a qualifying sales contract, the usual period is 14 days after the day the car comes into your physical possession. If required cancellation information was not supplied, a different extension rule may apply. Send a clear written cancellation notice in time and keep proof of when it was sent.
Can I cancel online even if the car is not faulty?
The qualifying distance-contract cancellation right does not require a fault or a reason. It is separate from Consumer Rights Act remedies. The Regulations allow a deduction for diminished value if handling went beyond what is needed to establish the car's nature, characteristics and functioning; the details and prior information matter.
What if the contract was not a distance sale?
A consumer buying from a trader may still have Consumer Rights Act rights if the car does not conform to the contract. The short-term right to reject is generally limited to 30 days after the statutory start conditions are met. Later remedies can involve repair or replacement first, then a price reduction or final rejection where the statutory conditions are met.
Can a dealer deduct use from a refund for a car?
A final rejection refund may be reduced for use. The Act's usual first-six-month protection against a use deduction has an exception for motor vehicles, so a deduction can be made for a qualifying vehicle within that period. This does not decide whether rejection is available or what amount is proper in a particular case.
What should I do if the car has a fault but the seller will not reply?
Keep the advert, order, invoice, delivery record, fault photos or video, diagnostic report and messages. Write to the legal seller with the dates, the fault and the remedy you are asking for. Do not treat a missed reply as proof of fraud or withhold an unpaid balance without checking the contract and getting case-specific advice.
General consumer information focused on a consumer purchase from a trader in England. It does not determine whether a particular car was faulty, whether the seller was acting as a trader, whether a contract qualifies as a distance contract, or which remedy is available. The order, seller, dates, use and evidence matter.
