NHTSA investigations into the 2016 Mercedes Benz GLC300

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

1 investigation is still open.

EA21002 Opened 17 Sep 2021 Still open AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE

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. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants.

STEERING

I am writing to express my deep concern and seek assistance regarding a potentially serious safety issue that I have experienced with my vehicle. I believe that my experience poses a significant risk to both my safety and that of other road users. In June, I encountered a distressing incident when my vehicle's steering wheel locked unexpectedly, leading to a hydroplaning incident that caused my vehicle to veer off the road. Fortunately, there were no injuries, but the situation was undeniably dangerous and alarming. My vehicle displayed a "steering wheel malfunction" message on the screen at the time of the incident. Following this event, I immediately contacted Mercedes Benz to report the issue and seek resolution. Subsequently, on August 1st, my vehicle was taken to a local Mercedes dealership as part of their investigation into the matter. On August 4th, I received a call from the dealership informing me that the inspection had been completed. However, they stated that they were unable to discuss the inspection findings with me directly, emphasizing that any communication regarding the investigation should come from Mercedes Benz USA. Despite my numerous attempts to communicate with Mercedes Benz USA through phone calls and emails, seeking information on the inspection findings and requesting a copy of the inspection report, there was no response or communication from the company. This lack of response and communication from Mercedes Benz left me deeply unsettled. However, I wish to update you that on August 31st, Mercedes Benz USA finally responded to my inquiries. While I appreciate their belated response, the substantial delay in communication further exacerbated my concerns about the safety of my vehicle and the responsibility of the manufacturer. Given the gravity of the incident and the potential risks associated with a steering wheel malfunction, I believe it is imperative that this matter is taken seriously and addressed promptly.

FUEL/PROPULSION SYSTEM

Mercedes-Benz USA (MBUSA) To whom It May Concern, Complaint through your dealer, regional MB and state AG. Going through MBUSA is a waste of time. You would be better off going to Sears and buying a shiny new hammer and banging your head every hour on the hour. A little over a year ago, I Purchase a previously owned 2016 GLC300 from a local DGDG dealership in San Jose CA. for the past few month, I started experiencing a heavy fuel odor generated from the fuel rail and fuel injectors. I initiated a leak detection to verify the above-mentioned defect. I became aware the Mercedes Benz has a major issue with the fuel rail and fuel injectors that caused a safety & emission recall campaign 2022030003 that is launched to replace the fuel rail and fuel injectors on 139 Model Year 2016-2020 that included my car GLC-class vehicle. To my surprise my car VIN number was not listed and flagged in this campaign. According to the campaign issue, a leak may develop between the fuel line and the fuel injectors due to trapped debris from the production process, which could affect the safety and emissions of the vehicle. according to the documents of the campaign, trapped debris might damage the seal between the fuel rail and fuel injectors, which over the life of the vehicle, might result in a fuel leak into the engine compartment. I informed Mercedes Bens that my vehicle fuel rail line and fuel injectors have shown to have a safety manufacture failure. Leaking fuel from this area might contact hot parts of the engine and therefore the risk of fire cannot be ruled out. It seems that the fuel pressure deviation has exceeded the thresholds because the fuel odor is perceptible to me. I had an appointment with Mercedes Benz of Stevens Creek, and they established that my vehicle VIN number was not affected by the recall even though the defects exist on my vehicle. I reached out to Mercedes Benz USA, LLC and filed case # [XXX] but they elected not to take responsibility to repair my ca INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I
