Mercedes-Benz A-Class (2012 – 2018) Review

Mercedes-Benz A-Class (2012 – 2018) At A Glance


+High quality interior. Strong diesels. A250 AMG Sport 4MATIC the best of the range. Big sellers and generally reliable.

-Handling not up to BMW 1 Series. Suspension fairly firm. Lot of complaints about 7G-DCT in B-Class, but not in A-Class.

Insurance Groups are between 13–33
On average it achieves 77% of the official MPG figure

After two incarnations of its sandwich-floor mini MPV, Mercedes Benz decided that its A-Class shoud be a conventional front wheel drive premium hatchback. It's lower and wider with a more muscular look as it aims to take on the likes of the Audi A3 and BMW 1 Series. (The B-Class retains the mini MPV design.)

The more purposeful look isn’t all for show though. Mercedes-Benz has put considerable effort into ensuring the body is stiff. This improves cornering and agility, making for a more engaging drive. Refinements to the suspension and steering have also been made with the aim of offering an involving, fun car. It’s effective – the new A-Class can be driven at speed with confidence.

While the shape of the car may be a radical departure, that doesn’t mean it's impractical. The boot is more than big enough for a trip away or a family shop plus the rear seats offer enough space for adults, even if headroom is a little tight. There’s plenty of technology on offer too and even basic models get a collision mitigating brake system designed to prevent and minimise low speed accidents.

Engines use the traditional Mercedes-Benz naming system. Six are available – A180 petrol and diesel, A200 petrol and diesel, A220 diesel and A250 petrol. The most efficient engine in the range is the A180 BlueEfficiency Manual which has CO2 emissions of just 98g/km. Enthusiastic drivers will go for the A250 ‘Engineered by AMG’ model which can accelerate from 0-62mph in 6.6 seconds.  

And don't worry if you've still got a soft spot for the old, more upright A-Class. Its spirit lives on in the B-Class, which gets many of the features of the new A-Class, but in a more spacious package.

Should I continue to have my car serviced by the dealer?
"I have a 2015 Mercedes-Benz A-Class with 10,000 miles, which has been serviced at a Mercedes dealership. Would you recommend I continue dealership servicing? My service plan has expired, should I pay annually or take out another plan? Thank you."
A premium car like the Mercedes-Benz A-Class will always be more desirable when it is sold with a full dealer service history than one without. That said, if you plan to keep the car for the long term then you may prefer to save money and have it serviced outside of the dealer network. There are some excellent independent Mercedes-Benz specialists out there. And the quality of the work will be just as good as the dealer and a lot cheaper. The only drawback will be the fact your car may miss out on updates that are usually applied by the dealer during the annual service.

My car isn't reliable and keeps refusing to start. Can I get my money back?
"I got my car - a 2015 Mercedes A-Class - at the end of January. Twice it’s been recovered from my drive as it wouldn’t start. The dealer I got it from is saying it’s a software update that needed doing that’s why it wouldn’t start the second time. I don’t understand how a software update will stop your car from starting! I’ve had a warning Light on saying “without changing gear consult workshop". Where do I stand? Can I ask for my money back? The dealer has covered the cost of everything so far but I have lost all faith and it’s not reliable."
If the dealer is unable to fix the car then you may be entitled to a refund, minus a fair deduction for the usage you've already had from the vehicle. However, given that these deductions can be quite expensive, it may be better to work with the dealer to find a solution. Personally, I would return the vehicle and ask them to replace it with another 2015 A-Class in similar spec. For your legal rights, see:

Can you trade-in a car that's worth more than the vehicle you are buying?
"A friend of mine has a three year old Mercedes-Benz A-Class, valued at around £16,000. She wants to buy a new Fiat 500 and expects to spend £14,000. Is this something a dealer will consider? "
They'll consider it. But the price they offer for the A-Class will probably be low, unless the dealer has a buyer lined up for the trade-in car. Your friend will be better selling it privately.

The turbo on my diesel car needed replaced after just five years. Should the manufacturer contribute?
"My five year old Mercedes-Benz A-Class diesel has done 36,000 miles. The turbo failed, resulting in a garage bill of £1700. It was repaired by a local Mercedes specialist as the dealer couldn't deal with the car for a month. Mercedes-Benz refuses to contribute. What's the general lifespan for a turbo on this model? Should Mercedes contribute in your opinion? Thanks."
The turbo is designed to last the life of the car. But problems in diesels usually develop when the vehicle is used for short journeys. Those 36,000 miles suggest that this car covers 7200 miles a year. This isn't enough for modern diesel engine. It has probably resulted in oil starvation to the turbo and/or oil contamination caused by the diesel particulate filter (DPF) failing to complete its regeneration cycle. Unless you plan to increase your mileage, my advice would be to sell the car and replace it with a petrol. Otherwise, further mechanical problems will be inevitable.
