Description of the Problem: I am reporting a severe vehicle fire that occurred with my 2015 BMW X4 (VIN: [XXX}) on [XXX], while I was driving on [XXX] in Orlando, Florida. This was a life-threatening incident. I narrowly escaped death as flames suddenly engulfed the front of the vehicle while I was on the road. For nearly two hours, it felt like a horror show. I am still in shock. After checking my VIN on NHTSA’s recall database, I discovered that my vehicle is part of Recall Number 24V608, which is still "Incomplete" and had no remedy available. The recall clearly describes a fire risk caused by liquid from the PCV system dripping onto the engine coolant pump’s electrical connector, which may lead to a short circuit and possibly a fire. I strongly believe that this is exactly what happened in my case. I am not a technical expert, but based on the description provided by BMW and NHTSA, it appears this recall defect directly caused my vehicle fire. I had no warning, no remedy notice, and no chance to prevent this. This incident has been widely covered by local news and emergency response teams: WFTV News Coverage WESH 2 News Coverage Orlando-News Article Orlando Fire Department's Official Post on Twitter/X This could have been fatal. Thankfully, no one was injured, but the mental trauma, financial burden, and risk to others on the road were immense. I am requesting NHTSA to investigate this case thoroughly and ensure that BMW is held accountable. These kinds of delays in remedies and safety actions are putting lives at risk. If needed, I can provide photos, videos, or any documentation you require.
