If Your Car Has a Problem After Collection
A fault after collection is frustrating, but it doesn’t automatically mean somebody has acted badly. Start by recording what’s happening, speak to the seller promptly and give them a fair opportunity to understand the problem.
Explain the symptom clearly, keep the evidence and contact the seller as soon as you can. Avoid paying another garage to carry out non-urgent work before the selling dealer has had the chance to inspect it, unless there’s a safety issue that means you must act immediately.

Record the fault properly
Note when it started, mileage, warning messages, sounds, how the car drives and the conditions in which it happens. A short video or photograph can help where safe, especially for an intermittent warning or noise.
Don’t clear a warning light simply to make it disappear. Record the message, then check the handbook and seek suitable help if the warning or the way the car behaves suggests it’s unsafe to continue.
Contact the seller promptly
Use a clear description first, then follow up in writing so both sides have the same record. A helpful dealer is common, and the quality of the response often matters more than the fact that a complex used car has developed an issue.
Give the seller a reasonable chance to inspect or diagnose before authorising non-urgent third-party work. If a safety concern means the car shouldn’t be driven, say so and keep the evidence.
Keep the issue in proportion
A used car can need consumables or develop a minor issue without that automatically being a major dispute. Tyres, brakes and servicing need to be judged by their condition, documentation, what was represented and what was agreed.
Warranty cover and consumer rights aren’t the same thing, and warranty terms vary. Check the position that applies to your own circumstances before drawing conclusions.
For guidance on an individual consumer issue, use Citizens Advice consumer guidance or appropriate professional advice rather than relying on a general guide.
When an independent report helps
An independent report can be useful where the facts are disputed or the issue is significant, but it isn’t always the right first move. Start with evidence and a proper conversation; escalate only where the response or the seriousness of the issue makes that necessary.
Keep invoices, the advert, order form, preparation promises, warranty documents and written correspondence together. They make the timeline much easier to explain.
Before collection, reduce avoidable problems
Inspect the car again, including glass, wheels, tyres, interior, keys and agreed work. Confirm the warranty documents, keeper-change process, tax and insurance before driving away. A proper collection check isn’t confrontational; it gives both sides a chance to resolve something while the car is still there.
A fair way forward
A clear record, a proportionate response and a reasonable opportunity to put things right usually get further than accusation. The goal isn’t to turn every fault into a fight; it’s to understand what happened and reach the right next step.
