Summary
The Mercedes-Benz GLB 250 has 14 recalls spanning the 2020–2025 model years, with the most serious recent issue being a tire sidewall defect on 2025 models where the right-side front and rear tires can lose pressure suddenly, causing loss of vehicle control.
The 2025 model year also has that tire recall as its only filing to date. Stepping back to 2021 models, the electronic stability program control unit can fail, disabling both anti-lock brakes and electronic stability control while also creating an electrical short that raises the risk of fire. That same year, certain vehicles were fitted with an incorrect front driver's airbag module that may not restrain the occupant properly in a crash and can detach from the steering wheel during deployment. A rear suspension level sensor linkage installed out of position on 2021 models affects automatic headlight leveling, which can project glare into oncoming traffic. Wheel arch covers on 2020–2021 models can detach and become road hazards.
The 2020 model year carries the heaviest recall load. Water can enter the cabin through the wheel well area and damage electrical components, causing the instrument cluster to go blank or the engine to stall while driving. On the restraint side, the airbag control software may not correctly fire the front seatbelt pretensioners or front passenger airbag in a crash, side curtain airbags may not deploy as intended, a window airbag catch strap in the A-pillar area can disconnect during deployment, and the front passenger airbag cushion can tear when the inflator fires. The second-row power outlet on 2020 models uses an incorrect voltage converter that can push excessive voltage to connected devices and start a fire. The second-row seat can sit misaligned in its track, preventing it from locking and leaving occupants less protected in a crash. The rear spoiler on 2020 models can shed pieces while driving, creating a road hazard.
