Engine & cooling
My 2020 Lexus NX 300 caught fire overnight while parked and unattended outside my residence. I discovered the fire the next morning. The Seattle Fire Department responded (incident #SFD-26-0112715) and their report states the fire originated in the engine compartment, with the cause of ignition listed as 'failure of equipment or heat source.' There was no collision, no theft, and no visible external damage prior to the fire. I am the original and only owner of this vehicle, with approximately 48,000 miles, and 100% of scheduled maintenance was performed at an authorized Lexus dealership (Lexus of Bellevue), with no aftermarket modifications. The fire also caused heat damage to a neighboring parked vehicle. I have reported this incident to Lexus Corporate Customer Experience and am seeking further investigation into the cause.
