This page covers 19 recalls and 51 owner complaints for the 2020 Mercedes-Benz Glb 250.
For the 2020 Mercedes-Benz GLB 250, the dominant complaint pattern centers on structural issues, which account for the largest share of owner reports by a wide margin. Owners frequently describe squeaking, creaking, and cracking noises coming from the suspension and undercarriage, particularly when turning, going over speed bumps, or driving at low speeds. Some reports tie these sounds to the front suspension and steering area, with a few owners also noting what they describe as misalignment or wandering behavior. Engine-related complaints round out the smaller clusters, with owners describing fuel system concerns and, in a handful of cases, cylinder head or internal engine issues. Suspension complaints echo the structural theme, with squeaking noises from control arms appearing across multiple reports.

By System
The 2020 Mercedes-Benz GLB 250 has 19 recalls, the most serious involving water intrusion through the wheel wells that can damage electrical components, causing the instrument cluster to go blank or the engine to stall while driving.
A corroding front axle carrier is another critical concern, as it can fail and cause a sudden loss of steering control. There is also a fuel injector seal that can leak near hot engine components, raising the risk of fire. Several recalls involve the restraint system: the side curtain airbags may not deploy in a crash, the front passenger airbag cushion can tear on deployment, a catch strap on the window airbag near the A-pillar may disconnect in a crash, and the airbag control software may fail to trigger the front airbags and seatbelt pretensioners properly. The second-row seat may not lock correctly in its track, leaving occupants less protected in a crash. The rear accessory power outlet may deliver excessive voltage to connected devices, which can cause a fire.
On the exterior, the rear spoiler and tailgate side spoilers may not be adequately secured and can shed onto the road, as can front fender wheel arch covers. Visibility is affected by a potential rearview camera software fault that causes a black screen when reversing, as well as headlights that may have been set to an incorrect angle. Two recalls address the emergency call system, which may either fail entirely or report the wrong location after a crash. The vehicle may also be missing the tool and instructions needed to check rear brake pad wear.
