Common car problems and how to check them before buying
The expensive problems to ask about vary by model, engine, fuel type and mileage. Duewise does not assign faults blindly; it uses structured model profiles where available.

Guide
What to check
Understand common used-car problems, model-specific weak points and the service evidence to request before viewing.
Examples of weak-point categories
Some cars need timing chain, timing belt, wet belt, turbo, DPF, EGR, clutch, gearbox, cooling-system or electrical evidence. The exact checks depend on the model and engine.
Ask for proof, not reassurance
Seller confidence is not evidence. Ask for dated invoices, mileage, parts detail and garage information for major repairs or known weak-point work.
When to walk away
Walk away if serious symptoms appear, warning lights are dismissed, the seller refuses a cold start, or expensive known weak-point evidence is missing and the price does not reflect risk.
