Summary
The Mercedes-Benz GLA is a mid-sized crossover vehicle, based on the A-Class hatchback and similar models (B-Class, CLA). The current model is the second generation, which arrived in the UK in summer 2020.
The GLA was originally launched with a range of petrol and diesel engines, with a plug-in hybrid option added to the range later in 2020. A higher-performance model called the Mercedes-AMG GLA 35 is also available – we are building a separate page for this model, so check back soon.
The Mercedes-Benz GLA has received generally good reviews from the UK motoring media since launch. It is considered a significant improvement over the original GLA, with more space and far better driving characteristics. It has also been praised for its sophisticated technology compared to rivals.
The biggest criticism, and the factor that has dragged its overall Expert Rating score down significantly below most rivals, is its high price tag. As of November 2022, the Mercedes-Benz GLA has an Expert Rating of 64%, based on 22 reviews published by UK media sources.

“The new Mercedes-Benz GLA 250 e is a competent all-rounder that offers a decent range, predictable handling and a plush, tech-filled cabin – not to mention low emissions and favourable company car tax rates

“The latest Mercedes-Benz GLA is a huge improvement over its predecessor. It now looks, drives and feels like a small, premium SUV. It has one of the finest cabins in its class and can now comfortably accommodate a small family.”

Model reviewed: 1.3-litre petrol/electric plug-in hybrid GLA 250e
Score: 8 / 10
“The new Mercedes-Benz GLA 250 e is plug-in hybrid motoring at its best, and for many prospective buyers this could be the GLA to go for. Impressive all-electric running combines with surprisingly sporty yet economical hybrid drive when the petrol engine is brought into play.”

“From hybrids to hot-hatch derived performance models, there’s a Mercedes-Benz GLA to suit all tastes and the tech and quality impresses on all – it comes at a price, however.”

Model reviewed: 2.0-litre diesel automatic GLA 220d AMG Line
Score: 8 / 10
“Tough competition, undoubtedly, and both British and Swedish challengers arguably offer more of the desirability and ‘special’ feel looked for at this price point. But in other, more objective areas, the Mercedes-Benz GLA is wholly competitive and well worthy of consideration.”

“Mercedes must be complimented on the new GLA. It’s a far more rounded and complete car than its predecessor, with greater dynamism and maturity to the way it drives, a considerably richer and roomier interior and improved levels of versatility and quality throughout.”

“Good-looking and spacious and decent-ish to drive, the most (supposedly) on-trend small Mercedes actually loses out in the charm and practicality race to the new GLB.”

Score: 6 / 10
“Good-looking and spacious, the snazziest small Mercedes is overwhelmingly expensive yet not as appealing overall as the more purposeful GLB. It’s a decent small SUV, but by trying to offer everything to everyone, this small Benz has lost some of its focus.”

“The Mercedes-Benz GLA is a stylish small SUV with a posh interior and plenty of high-tech features. It’s not as practical nor as fun to drive as other premium SUVs, though.”

“PHEV makes company car sense financially, and the Mercedes GLA PHEV is priced within reach of the regular petrol and diesel models.”

Score: 6 / 10
“It’s a big improvement on the outgoing car, but still one that doesn’t measure up to its rivals in key areas. If you’re a Mercedes loyalist I’d strongly suggest having a look at the GLB before you sign up for a new GLA.”

“While the old Mercedes-Benz GLA was little more than an A-Class with a moderate increase in ride height, the new model is a genuinely desirable little premium crossover.”

“The Mercedes-Benz GLA throws into the mixing bowl everything you like about the Mercedes A-Class – its posh image, high-tech interior and strong range of engines – adds an extra spoonful of practicality and a dash of SUV ruggedness.”

Score: 6 / 10
“It’s hard not to smile when behind the wheel of this car, but it’s very expensive and around town the drivetrain and ride quality are uncouth. That it drives better than it has a right to doesn’t alter the fact the German rivals do the job just as well if not better, and for less money.”

Model reviewed: 1.3-litre petrol/electric plug-in hybrid GLA 250 e
“In plug-in hybrid form, the Mercedes-Benz GLA is a potent performer and has the potential for low running costs, as long as you mostly do short journeys. It’s also great for families with its spacious cabin and decent-sized boot. However, refinement and fuel economy over long distances are less impressive.”

“The Mercedes-Benz GLA is a smart premium crossover, with high levels of comfort and technology. It’s safe and relaxing to drive, with plenty of passenger space and a decent boot. Fuel economy and refinement could be better, though.”

Reliability score
All data based on MotorEasy average workshop costs for extended car warranty claims
As of November 2022, the Mercedes-Benz GLA has a better-than-average reliability score of 61%, according to warranty data provided exclusively to The Car Expert by our partner MotorEasy. However, this score is based on a relatively small number of vehicles compared to other models, so is subject to significant swings. This score and data cover both the current GLA and previous (pre-2020) models.
The average repair cost of just over £600 is also about average for a mid-sized car, although still more than the cost of a used car warranty, which is worth bearing in mind if you own a GLA or are considering buying a used one.
The most commonly reported faults to date have been with the car’s electrical system, although it’s a relatively inexpensive fix at less than £200. Gearbox faults have been the most expensive issues, with an average repair bill of more than £2,000. Thankfully these appear to be relatively rare.
If you’re considering a used Mercedes-Benz GLA, make sure that any used car warranty you buy covers all of these problem areas.
