Advice for buyers
What should I look for in a used Mercedes B-Class hatchback?
All models have air conditioning, which is just as well, because the B-Class's large glass area means it can become quite hot inside on a sunny day.
There were two recalls for this generation of Mercedes B-Class, which were for potential fuel tank leaks and seatbelts that could possibly fail in an impact, so make sure any remedial work has been carried out.
Is a used Mercedes B-Class hatchback reliable?
As mentioned, at the time the B-Class entered production, Mercedes was getting over a period of reliability issues and there’s little doubt that extra effort was put into the B-Class to make sure that it would be solidly made. Mercedes even went so far as to offer tacit extended warranties on some components to make sure that customers would feel reassured.
That said, there are still some recurring problems. A loud whirring noise from the engines is usually a faulty pulley for the air-conditioning system, while a huffing noise from a diesel engine, or a smell of fuel inside the car, usually means leaky injector seals.
The central locking system and the lights by the sun visor mirrors can also give trouble, and they are surprisingly expensive to repair or replace.
