June 28, 2019—Tesla said a single battery module caused a car to catch fire in Shanghai, and it had revised its vehicle settings to protect batteries, reported Reuters.

A parked Tesla Model S caught fire in Shanghai on April 21. 

Following an investigation and analysis of the battery, software, manufacturing data and vehicle history, the investigation found no system defect. The fire was caused by a single battery module located at the front of the vehicle.

The company has revised the charge and thermal management settings on Model S and Model X vehicles via an over-the-air (OTA) software update, to help further protect the battery and improve battery longevity.
