Used Mercedes GLS

Well known for blending power and practicality, the GLS offers robust engines alongside high-end comfort and technology. Positioned as the flagship SUV in the Mercedes line-up, it is built for big families and even bigger adventures, praised for its commanding presence, adaptable seating, upmarket technology, and impressive space for people and luggage. Introduced in 2016 as the successor to the GL-Class, the GLS received a significant update in 2020, making earlier models great value for those wanting luxury without the latest price tag. Competition includes the BMW X7 and Range Rover, but the GLS holds its own with advanced driver aids, powerful diesel and petrol engines, and a vast interior designed for daily life and long trips.

Pros

A roomy people-mover
Dependable build quality
Generous standard equipment

Cons

High running costs
Large size makes parking tricky
Thirsty for a diesel

What are the key safety features of the Mercedes GLS?

The Mercedes GLS comes with a full suite of safety kit as standard: multiple airbags, electronic stability control, automatic emergency braking and a 360-degree camera. Some contain technology that stops this high-sided SUV from being affected by crosswinds on the motorway. Modern driver aids include active blind spot assist and an exit-warning function.
What engine options are available with the Mercedes GLS?

Earlier GLS models are often powered by a 3.0-litre V6 diesel, while the latest generation offers a 3.0-litre petrol engine with mild-hybrid technology. Range-topping AMG versions use a 4.0-litre V8 petrol. All engines are paired with a smooth automatic gearbox.
What are the standard technology and infotainment features in the Mercedes GLS?

As a luxury SUV with a cockpit-like cabin, you can expect to find dual 12.3-inch screens, satnav, DAB radio, Bluetooth, Apple CarPlay and Android Auto in the GLS. Premium touches like ambient lighting, multi-zone climate control and electrically-adjustable seats are common. Some versions include Harman Kardon sound systems and heads-up displays.
What is the fuel consumption of the Mercedes GLS?

Fuel consumption varies by engine and year. Most diesels get between 27 and 37mpg, while petrol engines average 20 to 27mpg. More powerful AMG and Maybach versions are thirstier (20mpg at best on a good day). It’s not the most efficient SUV, but that's expected for its size and power.
What should I check when buying a used Mercedes GLS?

Inspect the bodywork and alloy wheels for scuffs from use – this is a supersized vehicle that's challenging to park. Check all electrical equipment works; pay special attention to the air suspension for leaks or warning lights. Examine the interior for wear and ensure service history is complete. A professional look by The AA Vehicle Inspection can offer extra reassurance.
Are Mercedes GLS cars reliable?

The GLS is a complex, luxury SUV – more features could mean more potential issues. Mercedes' reliability has improved, yet surveys still place it mid-table among premium brands. Repair costs can be high, but many owners report solid mechanical dependability if time and care are taken over maintenance.
