When the fourth-generation Mercedes-Benz GLE (W167) landed in South Africa in late 2019, it arrived with a mission: win back the premium-family-SUV crown from the BMW X5 and Audi Q7. Replacing the sturdy but aging W166, this version was a full rethink—structurally and electronically. Mercedes brought in a complex, “digital-first” setup that centers on screens, while also rolling out refined 48 V mild-hybrid tech. As these early W167s start to show up on the used market, here’s what you need to know before you buy.
A rundown on the Mercedes-Benz GLE
The exterior of the W167 is all about better aerodynamics, lowering the drag coefficient to 0.29. The wheelbase was stretched by 80 mm versus the previous model to boost interior space and high-speed stability. The AMG Line look is popular in South Africa, giving the SUV a bold stance with a diamond-pattern radiator grille, large air intakes, and big 20- to 22-inch wheels.
Inside, Mercedes’ MBUX infotainment system takes center stage. The dashboard features dual 12.3-inch high-resolution displays tucked under a single, wide glass panel. There are no traditional physical controls; instead you get capacitive touch surfaces, advanced voice tech, and steering-wheel haptic buttons. The extra 80 mm of wheelbase means more legroom in the second row, and boot space grows to 825 litres, expanding to 2 055 litres with the rear seats folded flat. An optional third row allows part-time seven-seat use, though the rear space is best left for smaller passengers.

At launch, the South African engine lineup featured smooth, torque-rich motors paired with Mercedes’ 9G-Tronic nine-speed automatic and fully variable 4Matic all-wheel drive. The entry GLE 300d 4Matic runs a 2.0-litre four-cylinder turbodiesel, producing 180 kW and 500 N.m of torque, with a claimed fuel use of around 6.1 L/100 km. For more refinement, the GLE 400d 4Matic uses a 2.9-litre inline-six turbodiesel, delivering 243 kW and 700 N.m.
Besides the diesel crowd, the petrol lineup is led by the GLE 450 4Matic. It has a 3.0-litre turbo inline-six, making 270 kW and 500 N.m, and it includes EQ Boost 48 V mild-hybrid tech, providing an extra 16 kW and 250 N.m for short bursts to reduce turbo lag and smooth engine start-stop operations.
Things To Look Out For When Buying Used
– 48 V mild-hybrid battery failure: The EQ Boost system in the GLE 450 relies on a dedicated 48 V battery, which can degrade quickly if the car sits idle.
– AIRMATIC suspension integrity: Models with the optional AIRMATIC air suspension are prone to leaking air struts or a failing compressor. Look for an uneven ride height, a car that sags after overnight parking, or hissing sounds from the wheel wells when the system kicks in.
– MBUX software instability: The highly digital cabin can suffer from software glitches. Early units may see screens freeze or touch inputs become unresponsive. Make sure the firmware has been updated to the latest version at a franchised dealership to reduce these issues.
– Transmission hesitation: The nine-speed automatic is generally solid, but some units experience jerky or hesitant shifts in stop-and-go traffic.
– DPF and AdBlue sensor malfunctions: On the 300d and 400d, short urban trips can clog the diesel particulate filter and trigger AdBlue sensor failures, which can push the engine into a restrictive limp mode.
Which one to get
The GLE 400d 4MATIC is the clear best buy. The 300d may be adequate in number, but a SUV weighing over 2 300 kg really benefits from the low-end punch of a large-capacity inline-six diesel. The 2.9-litre engine delivers a massive 700 N.m of torque, making overtakes and towing effortless, while still offering better real-world fuel economy than the petrol mild-hybrids.
