LEAF has the numbers, only one fire that I'm aware of, no determination as to the cause that I can find, and I've looked, a lot. The Bolt should have around 40K cars on the road by now, never heard of a fire.
40K is still too low to draw conclusions, given that there are something like 500,000 Teslas on the road.
There have been Volt fires. I also wonder what caused the apparently-spontaneous Leaf fire.
It shouldn't be a surprise, Tesla does use a more energy dense, and volatile cell chemistry.
I think Tesla also attracts more reckless drivers, which is frankly the cause of many of the reported Tesla fires.
Neither the Leaf nor the Bolt is advertised as a "speed demon" car, so they don't attract the reckless drivers.
There are a pretty small number of fires which don't fall in the reckless-driver category. The two underside puncture fires from before the titanium shield was added; the one in the garage which was on fire; the two wiring defect fires; and this one, which was probably improper towing, but might have been another wiring defect (given that it started in the front of the car).
At the same rate of non-reckless-driver fires, you'd expect the Bolt to have had less than half a fire so far (i.e. zero).
The Leaf does have the numbers to potentially say that it has a lower rate of fires than Tesla; 1 when you'd expect 4. Still not statistically very solid there...
Of course, gasoline cars have ten times higher rates of fires than Teslas do. And the fires are far more deadly. Nobody's died in an electric car which caught on fire except the reckless drivers & their passengers who were killed due to impact, and not even all of them.
