The spontaneous combustion of several Tesla vehicles in recent weeks has forced the automaker into action, issuing over-the-air updates in an attempt to snuff out the problem… and smother another round of bad PR. To its credit, Tesla seems to be taking the matter seriously.

The update covers the company’s Model S and X vehicles, regardless of country. Meanwhile, investigations continue into the cause of recent blazes in Shanghai, San Francisco, and Hong Kong.

Former Tesla PR man Daryl Siry’s Wired.com Autopia columns are always good for some interesting insights on the EV world… as long as you take them with the grain of salt that Siry’s status as “advisor” to EV startup Coda Automotive demands. This week Siry has it in for the mass-market EV frontrunner, the Nissan Leaf, accusing its makers of “cutting corners” and “overpromising” range specs. According to Siry:

First, Nissan overpromised on the realistic range by consistently quoting a number tied to the most optimistic benchmark, the LA4 cycle. Drivers who stick to stop and go traffic on city streets in temperate climates may indeed consistently see 100 miles of range, but most drivers will see significantly less in a mix of city and highway driving. Driving in California, the country’s top market for electric vehicles, involves a lot of time on highways where the 65 mph speed limit is rarely observed. The LA4 cycle Nissan quotes mostly stay below 30 mph with one two-minute “sprint” at 55 mph every 22 minute cycle.
