Owner reports
Selected complaints filed with NHTSA by 2014 Mercedes-Benz C300 owners, lightly cleaned up (personal details are redacted by NHTSA).
While I was driving my car the driver side airbag abruptly deployed. The airbag inadvertently deployed; the car did not crash into anything to cause the airbag to deploy. When the airbag erupted it caused injury to my head, face, hand, arm and wrist. I believe the airbag is defective because I have lacerations on my face possibly due to sharp objects ejecting from the airbag and the impact as well as excessive smoke and fumes emitted after the fact. I believe there might be a manufacturing defect in the airbag because it seemed as if it exploded with excessive force causing harm to myself as well as inadvertent eruption. There have been some recalls issued on the motor vehicle and I did take the vehicle to the Mercedes car dealership to get all of the recalls repaired, however this incident occurred after the repairs were made at the dealership.
I received a notice several years ago for the airbag to be replaced due to a recall. Mercedes-Benz has not been able to remedy this issue for years. I have called for several years, but the Mercedes dealer near me continues to state that the airbag part is not available. I called Mercedes hotline [phone]) a month ago to report the issue. No one answered so I left a voicemail. I received no contact from them. I called last week 3 times in a row and finally someone answered. I opened a claim with them for the escalation team. They said I would receive a response in 48 hours. I received no response.
Takata recall. The contact owns a 2014 Mercedes-Benz C300. The contact received notification of NHTSA Campaign Number: 19V010000 (Air Bags) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.
I purchased my vehicle from the Mercedes Benz Dealership and received a recall letter in the mail stating that driver side deployment may occur. After receiving notice I brought the car to the dealership to get the recall repaired. I've been driving around with a false sense of security believing that this issue was repaired. However, recently, while I was driving the driver side airbag unexpectedly and abruptly deployed and injured me. This is a major safety concern and car owners should be notified and made aware that the issue can still occur after the recall was repaired. I contacted Mercedes Benz and they did not issue any additional notices to inform customers of possible recall issue reoccurring due to manufacturer defects even after the repair was made. …
While in motion (driving) another driver turned in front of me, causing me to t-bone her (police report with description attached). I slammed on brakes to to lessen the unavoidable impact. I estimate my speed at 30-35 MPH. My airbags failed to deploy. My car was totaled, as was the other driver I hit. I had 2 spiral metacarpal fractures in my left hand from hitting the steering wheel that required surgical placement of two plates and 12 screws, and my knees hit the dash board, my right hip bruised from seatbelt,I sprained neck and back and partially torn left rotator cuff. All of the other drivers airbags deployed, and she walked away from the accident. Not one of my airbags deployed.I was taken to the emergency room via ambulance from the scene. My left pant leg was cut by paramedics to see my knee that had obvious bruising and swelling. …
Takata recall - I received notification in October 2017 tk holdings inc.'s chapter 11 bankruptcy. This was the first notification that I received that my 2014 Mercedes C300 had a recall. The manufacturer and dealer never provided one. I looked up on-line regarding the recall and discovered my car is affected. I had scheduled services at the denver Mercedes dealership on 12/28/17 and took in the documentation I had received/discovered on-line and asked my service rep about it. He told me that I needed to go on-line and register. That was it. If my car has been recalled for a safety reason I certainly deserve more of an explanation than being told to go register on-line. When will the defect be rectified and when will the manufacturer/dealer correct the defect so that I am not in danger?

Takata recall. Consumers have been in a waiting period for a tragedy to happen with the SRS . When will a solution be provided by the manufacturer and available to consumers? I do not want anything to happen to me or my family members because of a slow or no response in solving this SRS problem. I do not need the money, but I do want to keep my health and life!!

NHTSA investigations
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
