Tesla Reports Zero Spontaneous Battery Fires Across 265 Billion Miles

Tesla published a detailed engineering page on September 1 titled 'Engineering Tesla Vehicle Batteries for Safety, Durability and Longevity,' claiming no evidence of a single spontaneous battery failure leading to a vehicle fire across more than 265 billion miles of operation through the end of 2025 in Model 3, Model Y, Cybertruck and Semi. The company says its overall vehicle fire rate is roughly one fire per 140 million miles, about eight times better than the U.S. average of one per 17 million miles. Tesla highlighted its Passive Propagation Resistance design philosophy and dry electrode manufacturing, noting it is the only battery maker using dry cathode technology at scale, with 100% inspection via automated vision and X-ray scanning.
