Summary
First arriving on UK roads in the second half of 2012, the third-generation Mercedes-Benz A-Class was a five-door family hatchback pitched as a direct rival to the likes of the Audi A3 and BMW 1 Series. It was replaced by the current generation of the A-Class in 2018.
The range consisted of a selection of four-cylinder petrol or diesel engines, available with either a six-speed manual or seven-speed automatic gearbox.
“Whichever you get, it’s worth paying for the automatic gearbox”, Carwow said. “It’s smooth and changes gears quickly, unlike the manual gearbox, which is not so nice to use.” Other than the transmission, Parkers said that the A-Class had “compromised” ride comfort, which What Car? also called “unnecessarily firm”.
Many motoring titles also comment that the A-Class lacked practical space when compared to its key rivals, and that it was not all that fun to drive – The Telegraph argued that “the A-class isn’t the kind of car that will tempt you into taking the long way home.”
While a bit dated toward the end of its life, the interior build quality and refinement was a highlight, and many journalists were impressed by the exterior design of the A-Class through the years – both after its launch, and its mild facelift in late 2015.
And despite the range of efficient engines available, “The A-Class just isn’t quite as good as it should be”, Carwow concluded. “Yes, it looks amazing, but it’s not as classy or as practical as alternatives.”
As of May 2024, the third-generation Mercedes-Benz A-Class holds a Used Car Expert Rating of C, with a score of 60%. It gets good grades for its low running costs and strong reliability record, but its safety rating has long expired and its media review scores were poor.

“With decent tech and a broad engine range, the Mercedes A-Class is a strong premium hatchback – but it’s not quite the best of its era.”

“The good bits of the A-Class are really good, but there are some fundamental flaws, most importantly an average driving experience and mediocre cabin space.”

“The Mercedes A-Class impresses on interior quality and styling, and it’s as desirable as a Benz should be. It’s nowhere near good enough for ride or handling, though, and it also disappoints on refinement, ergonomics, practicality and value for money.”

“Mercedes-Benz finally hit the premium hatchback bullseye with this generation of A-Class. Even today, it still looks fresh and attractive, and has a coupe-like feel inside, yet is surprisingly affordable to run. It’s not the most practical of cars, which will hinder its appeal for some, but otherwise it’s hard to find fault with a model that proved to be deserved sales success.”

“The A-Class is a posh, easy-going Merc that should fit in city parking spaces and shouldn’t cripple you on company car tax. It’s no madcap hot hatch, the A-Class, but it’s a classy little thing.”

What Car?
Model reviewed: 2016 update
“The extra 7bhp that’s been gifted to the 174bhp A220d doesn’t make much difference to the A-Class on the road – this four-cylinder diesel is still decidedly gritty sounding, but it does deliver a healthy kick when you want it.”

“The third generation A-Class was longer, lower and infinitely more stylish, while conforming to the class norm, unlike its upright and stubby predecessors.”

Notes on safety rating
The Mercedes-Benz A-Class was originally crash tested by Euro NCAP back in 2012 and awarded a five-star rating. However, this rating expired in January 2019 and is no longer valid as the car no longer meets the standards required for such a rating. This is normal practice, as Euro NCAP reviews its ratings on most cars annually with most ratings expiring after about six or seven years.
However, if you are comparing a used A-Class to vehicles of similar age, whose ratings will have probably also expired, its safety rating score is still useful.
Eco rating

The third-gen Mercedes-Benz A-Class was not lab tested by Green NCAP during its life cycle as it pre-dated Green NCAP.

Reliability score
All data based on MotorEasy average workshop costs for extended car warranty claims
As of May 2024, the Mercedes-Benz A-Class is better-than-average in its reliability score, according to warranty data provided exclusively to The Car Expert by our partner MotorEasy. This data covers not only this A-Class (2012 to 2018) but also newer (2018 onwards) and previous (pre-2012) models.
The average repair cost of more than £550 is fairly high for a mid-sized car and also more than the cost of a used car warranty, which is worth bearing in mind.
The most commonly reported faults to date have been with the car’s braking system, which is a relatively cheap fix at less than £200. However, there have been a reasonable number of claims for gearbox faults, which has an average repair bill of about £2,000.
