2018 Mercedes-Benz GLA 250: airbag warning light

Filed Sep 14, 2026 · Airbags, Electrical · FL

After the vehicle's main battery fully discharged and the vehicle was jump-started, multiple SRS / driver airbag warnings appeared immediately, the horn and steering wheel controls stopped working, and a clicking noise developed in the steering column when turning the wheel. None of these symptoms existed before the battery discharge / jump-start event. Mercedes-Benz of Sarasota (Repair Order / Invoice 675113) performed XENTRY diagnostics and documented fault codes B000113 and B000213 (driver airbag squib stage 1 and stage 2 malfunction - open circuit), U100800 (LIN bus 1 malfunction in the steering column module), and B1F4500 (starter battery excessive resistance current; 12V battery failed test). The technician documented the root cause as "defective steering angle sensor and internal wiring of steering column module, thus no completed electrical circuit to driver airbag and steering wheel," and noted that the vehicle is unsafe to drive because the driver airbag will not deploy in a crash. Mileage approximately 73,447. No crash, fire, or injury occurred - the defect was discovered as a non-functioning driver airbag. I am reporting this because the failure mode appears related to the steering column module / clock spring / driver airbag circuit addressed in the federal safety agency recall 17V627 (MB campaign 2017110011), for which this VIN is not included; this vehicle was produced after the recall's stated production cutoff. Three dealership managers stated in writing that the failure was mechanical and unrelated to the electrical event, which is inconsistent with their own technician's documented electrical root cause. The dealership's Service Director stated he could not determine why the failure occurred. Mercedes-Benz USA (case 24257427) has not performed any engineering or product safety review of this failure. I request that the federal safety agency evaluate whether steering column module / driver airbag circuit failures are occurring in vehicles built after the 17V627 production cutoff.

The vehicle experienced a sudden, total communication network crash on [XXX] the vehicle simultaneously triggered cascading critical safety system faults including “ inoperable” messages for the SOS system, Supplemental Restraint System ( SRS) and antilock brake system(ABS) along with check engine light on dashboard. The car locked itself in park and completely refuses to engage any drive gears. I took it to the dealer in Henderson, NV and they reported to me on Dec 24, 2025 that it will be a $1200 diagnostic and the repairs can be thousands of dollars. Since then I have taken it to 5 European and independent shops and have spent thousands of dollars for guess work. This happens sporadically I have been broken down where tow trucks have to retrieve my car and take to a shop where they have no clue of the issue. I am scared to drive it if it stalls on the streets and have a major accident. No problem has been resolved INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
