    Common Faults


    Guide Price £ TBC

    Navigation System – It can lead to some misunderstanding if voice operated. However, since there are many people complaining about it, especially compared to other navigation options, we feel confident that a software update should up the game in this respect.


    Transmission – There have been problems with engaging reverse gear. It lags and when a bit of throttle is applied, it engages violently. An owner reported that the problem has been solved using engine and transmission software update. Also, several owners complain of slow shifting of the automatic, as well as slow kick down.





    No recalls to report. Please let Star-Tec Engineering Ltd know if one has come out we have not shown.


    Model Types


    The GLA comes in one form alone. It is a compact crossover with four doors, with the engine mounted at the front and with front- or four-wheel drive. All of the currently available engines are I4, while there are two transmission options – manual and automatic. The car is heavily based on the A-Class, but it is also significantly different.


    The most powerful option comes in the form of the GLA45 AMG, packing again a I4 engine, but this time with two turbochargers for the power rating of 355 hp.


    Trim Lines & Engines


    There are two trim levels available for the GLA, but there are a significant number of equipment packages as well. The entry level trim is called SE and it includes things such as reversing camera, air conditioning, multi-function steering wheel and digital radio, as well as other comfort perks. The AMG Line trim level ups the aggression of the exterior and gives firmer suspension and larger wheels.


    Packages come as follows:


    Executive – includes heated front seats, folding mirrors and autonomous steering while parking (Active Park Assist).


    Premium – comes with bi-xenon lights for the front and electrical tailgate.


    Premium Plus – adds Intelligent Light System, panoramic sunroof and dual-zone air conditioning.


    Exclusive – adds additional colours for the interior leather, electric front seats and better floor mats.


    Driver’s Assistance Package – comes with adaptive cruise control, Blind Spot Assist and Lane Keeping Assist.


    If you opt for the AMG Line, you can also add Night package which gives black mirrors, bumper details, roof rails and 19” wheels.

    Model History


    The GLA part in the name tells a lot about this car’s origins. First of all, the “GL” stands for an SUV, while the “A” means that it is based on the A-Class. This is why the GLA is the smallest SUV in the Mercedes-Benz line-up, much like the A-Class is the smallest Mercedes offered. It shares the platform with the current A-Class and B-Class, while it is also similar to the CLA-Class sedan. However, being an SUV strongly distinguishes the Mercedes-Benz GLA and puts it in a class of its own to compete with other upmarket compact SUVs.


    After two concepts presented in 2013, the car became available a year later. Such a short time between the concepts and production cars means that these are very similar both in design and technical specifications and solutions.


    The same year saw the first AMG model which packs plenty of styling and performance additions which do not only serve to make the car look more aggressive, but also help it deal with class-leading 355hp of power.
