Common questions
About this generation
Which years does this page cover?
2006–2014. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.
Does the fault apply to every car like this?
No. It depends on the engine and the transmission too.
Is it free?
The fault list is.
Information, not an expert opinion
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
- A fault on the list does not mean the car you are looking at has it.
- A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
- You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
