Safety is paramount in any vehicle, and the Mercedes-Benz GLB, unfortunately, encountered airbag-related issues. In a recall in August 2021, certain GLB models were identified as having a potential design defect leading to malfunctioning seatbelts and airbags in the event of a crash.

This hardware and software-related flaw demands immediate attention from certified Mercedes-Benz mechanics. Instances where airbags fail to deploy and seatbelts malfunction could result in severe consequences, potentially endangering lives.

Addressing this problem may involve replacing or revising the airbag control module.

Fuel and oil leakage problems are not uncommon in the automotive realm. For the Mercedes-Benz GLB, some instances of fuel leakage have been identified, often linked to the flawed process in certain models.
