My engine caught on fire in the middle of the night ([redacted] on [redacted]). The fire department was called by my building's security and they came to put out the fire. The security footage shows that the car engine caught on fire for no apparent reason. The fire department did not identify any foul play or vandalism nor did the security camera footage. Unfortunately since my car has been paid off, I only had liability coverage and could not get the coverage to assess. I had to junk the car. No one was hurt but there was broken glass and some parts around the parking lot due to fire and fire department having to shatter and pry open the engine bay. Please advise if someone can help me in my situation. Also this should be made aware to Hyundai. There was a recall but I was never notified. Nor does any recall history show up for this.
