Failure Date: 08/17/2025

On August 17, 2025 I rearended a vehicle in front of me who jammed on their brakes for no apparent reason. We were the only two vehicles in the area. Upon impact, the following airbags deployed. . . . Steering wheel, driver knee airbag. I sustained injuries to my lower extremities from the exploded knee airbag which contained metal components that impaled my skin. I continue to receive treatment for multiple injuries and the wounds that have not healed. My safety was at risk due to the metal components (shrapnel) deployed via the exploded knee airbag. I also sustained injuries my left wrist from the steering wheel airbag, and my left chest from the tightening of the seatbelt. The local Mercedes Benz dealer recently towed the vehicle from my home address to their facility for inspection of said airbags. As of today, I have not received any report from mbusa.

4 Seat Belt problem of the 2010 Mercedes Benz GLK350

Failure Date: 04/21/2018

Takata recall: good car into south bay mercedes for srs replacement as instructed on recall letter. Service advisor initially told me to pay for diagnostic prior to moving forward, but after I insisted that the issue was related to a recall notice, I was told the replacement of the srs module would be free of charge. After completed, advisor showed me that the warning was no longer active as the problem was fixed; as soon as I left the lot, the srs warning reappeared so I returned. Service advisor instructed me to then pay for a diagnostic as previously suggested because it was unrelated to the recall. Service advisor, roger, would not inspect vehicle any further without collecting payment. On the drive home, car was smoking; discovered oil all over the engine once I arrived at my destination (oil change performed as well). No recourse after contacting south bay mercedes-benz. ; manager not available. I need immediate assistance as this is a safety issue that is not being addressed by mb USA.

5 Seat Belt problem of the 2013 Mercedes Benz GLK350

Failure Date: 06/13/2016

On may-June 2016 the vehicle was showing a warning light related to a malfunction of the driver's seat belt, the dealership found through a vehicle inspection that it was related to the steering module. One was ordered. The airbags were disable for a month, placing at risk my wife's life. The problem seems to be fixed but the airbags now could be disable or will malfunction in the future. Since this type of vehicle has takata airbags, I would like to request the replacements of all airbags, instead of a trial/waiting if this will malfunction in the near future, with a risk of a preventable death of me of my wife, as we both are driving this vehicle. I appreciate placing human lifes instead of monetary gain.
