Summary

The Mercedes-Benz CLA is a compact saloon and estate model, based on the 2018 Mercedes-Benz A-Class. The current model is the second-generation CLA, which was launched in 2019. It is due to be replaced by the third-generation model later in 2025.

Mercedes-Benz refers to the saloon model as a ‘four-door coupé’ and the estate model as a ‘shooting brake’, however neither is correct and it’s simply marketing spin based on the CLA being lower and sleeker (and more expensive) than the A-Class models that it’s based on. There are higher-performance models called the Mercedes-AMG CLA 35 and CLA 45, which are not covered here. We are building separate pages for these models, so check back soon.

The Mercedes-Benz CLA has received generally positive reviews from the UK motoring media. It has received praise for its styling and high levels of advanced technology. However, its sleek compromises its space and general practicality, and consumer titles have marked the CLA more harshly than its A-Class siblings as a result. The CLA is available with a choice of petrol, diesel or plug-in hybrid powertrains. The petrol and diesel engines were available from launch in 2019, with the plug-in hybrid version added in early 2020.

A facelifted version of the Mercedes-Benz CLA arrived in the UK in Autumn 2023. This consists of a collection of minor updates to the existing car, rather than a major upgrade.

An all-new CLA range, including the first all-electric versions, was unveiled in early 2025 and is set to go on sale in the UK over the summer.

As of July 2025, the Mercedes-Benz CLA has a New Car Expert Rating of B, with a score of 68%. It scores top marks for its low CO2 emissions (helped by the plug-in hybrid version), while its safety rating is also good. However, its media review scores have only been average and its reliability record has been poor.

Reliability rating

Reliability data provided exclusively for The Car Expert by MotorEasy

All data based on MotorEasy average workshop costs for extended car warranty claims

As of April 2025 (our most recent data point for reliability), the Mercedes-Benz CLA has a below-average reliability score of 59%, according to workshop and extended warranty data from our partner, MotorEasy, sourced from both official dealerships and independent workshops. This rating covers both this generation (2019 to 2025) and the previous model (2012 to 2019). 

The average repair costs to date are also fairly high for this size of car, at just under £700. The most expensive bills so far have been for gearbox repairs, with an eye-watering average bill of more than £3,000. Fortunately, they have not been common.

Engine problems, however, have been both common and expensive with an average bill of about £800.

If you’re thinking about buying a used car warranty for your CLA, make sure that it covers all of the problem areas shown above.

Running costs for the Mercedes-Benz CLA are slightly higher than for its A-Class sibling, according to numbers provided exclusively to The Car Expert by our data partner, Clear Vehicle Data.

Fuel consumption for petrol models is average, although diesels are better. The plug-in hybrid looks good on paper, but this is deceptive – every plug-in hybrid looks great in theory, but this is because of rubbish EU/UK government lab testing. You certainly won’t get 248 miles of driving from one gallon (4.5 litres) of fuel and a bit of electricity…

The battery range of the plug-in hybrid is reasonably good, at 42 miles according to the official tests. That’s better than most plug-in hybrids, but you’ll still need to charge it almost daily to get best use out of the electric motor and battery. By comparison, an equivalent mid-size full EV would get more than 200 miles out of its battery so most households would only need to charge it once a week.

Scheduled servicing costs have become more expensive in the last year or so, with our latest data showing that costs are now average over the first five years – having slipped from a B to a C grade.
