Beware Of The Sell Your ‘Faulty’ Car Scam
Selling a used car should be simple — but scammers are constantly inventing new ways to deceive unsuspecting sellers. One of the most alarming tactics on the rise is the “sell your faulty car” scam, where fraudsters deliberately tamper with a vehicle to make it appear broken, then pressure the owner into selling it for far less than it’s worth.
Here’s how the scam works, how to protect yourself, and what to do if you’re targeted.
How the Scam Works
This scam usually involves two or more fraudsters posing as genuine buyers. They ask to inspect the car, often appearing friendly and knowledgeable. While one distracts the seller — asking about paperwork, service history, or minor cosmetic details — the other secretly tampers with the engine.
A common trick involves:
- Pouring oil into the coolant system, causing smoke when the engine starts
- Loosening components to create rattling or knocking noises
- Interfering with sensors to trigger dashboard warnings
When the car is restarted, it appears to have a serious mechanical fault. The scammers then claim the vehicle is worthless and offer to “take it off your hands” for a scrap‑level price.
Real‑Life Cases Across the UK
This scam has been reported nationwide. In one case, a BMW owner caught two scammers on CCTV attempting to convince him his car was on the verge of engine failure — offering just £2,000 for a vehicle worth far more.
Similar incidents have been reported in Manchester, Kent, and other regions, all using the same tactic of tampering with the engine to create fake faults.
Why This Scam Works
Fraudsters rely on:
Shock and Panic
Seeing smoke or hearing strange noises can make even confident sellers doubt their vehicle’s condition.
False Expertise
Scammers often pretend to be mechanics or experienced buyers, reinforcing the idea that the car is unsafe or damaged.
Pressure Tactics
They may insist the car is moments away from breaking down, pushing sellers to accept a low offer quickly.
Convenience
Some sellers simply want a fast sale and accept the offer without seeking a second opinion.

How to Protect Yourself
You can avoid falling victim to this scam by taking a few simple precautions:
1. Supervise all inspections
Never leave buyers alone with your car — especially under the bonnet.
2. Stay calm if a “fault” suddenly appears
Scammers rely on panic. Take a moment to assess the situation.
3. Get a second opinion
If a buyer claims there’s a major issue, speak to a trusted mechanic before making any decisions.
4. Avoid rushed or aggressive offers
Genuine buyers won’t pressure you into selling immediately.
5. Use reputable selling platforms
Selling through trusted comparison sites or verified dealers reduces the risk of encountering fraudsters.
Reporting a Scam
If you believe you’ve been targeted:
- Report the incident to Action Fraud
- Contact your local police
- Provide any evidence, such as CCTV footage, messages, or descriptions
Reporting helps protect other motorists from falling victim to the same tactics.
Final Thoughts
The “sell your faulty car” scam is becoming increasingly common, but with awareness and caution, you can protect yourself. Always supervise inspections, question sudden faults, and seek professional advice before accepting any suspicious offers.
Selling your car should be a fair, transparent process — don’t let scammers take advantage of your trust.
