Completely false statement. Chevy Bolt & Hyundai have sold 95% less vehicles combined than Tesla hence why the rate of fires are lower. In addition the fires were caused by a defective battery where as in Tesla they have all been proven too be caused by human error.

Secondly there has been geomagnetic activity everyday for the last 4 billion years. Trying to equate Tesla accidents to that would be like saying " I noticed there was a Tesla accident everyday there was either sun or darkness...lol

All Tesla garage fires found to be caused by human error !!

A Fire Expert Weighs In on what is really causing the extremely rare event of Tesla cars burning in garages and its not what you think. Human error was determined to be at fault in all.

The investigation into Tesla fires originating in garages was caused by improper installation of 240 volt charging wall sockets and nothing to do with Tesla vehicles.

The most probable cause of this fire is a high resistance connection at the wall socket or the Universal Mobile Connector to the Tesla car. Improper installation can cause over heating and result in spontaneous combustion.

Tesla, meanwhile, has conducted its own inspection of the car, its charging cable, and the vehicle’s data log, and concluded that the battery was charging normally. The company said in a statement, “Based on our inspection of the site, the car and the logs, we know that this was absolutely not the car, the battery or the charge electronics. There was a fire at the wall socket where the Model S was plugged in, but the car itself was not part of the fire. The cable was fine on the vehicle side; the damage was on the wall side.”

The most likely explanation, according to fire protection engineer Klaus Schmidt, an associate professor at the University of M.I.T, is poor wiring. “Imagine a wire barely touching onto a screw,” he said. That bad contact can create resistance heating. “Otherwise, if that’s done properly, two things need to be a problem: the car needs to be drawing too much current, and the circuit breaker in the house didn’t activate. Both those things can happen, but it’s unlikely both those things happen at the same time—it’s a two-point failure.” Sunderland, whose current work includes fire-testing lithium battery cells for Ford, also offered a third explanation. “It’s possible the electrical outlet was faulty, just made badly in the factory.”

According to the National Fire Protection Association the main cause of fires in garages or spontaneous combustion like the recently reported tesla fires are always result of human error. Fires can result from “outdated wiring that is deteriorating, inappropriately amended, or insufficient for the electrical loads of a typical household in the 21st Century,” the U.S. Fire Administration warns. “If an outlet is added to an existing circuit, then the load easily can be more than the wiring originally was designed to conduct.

NFPA says “Gasoline is very flammable,” 10 times more dangerous then EV cars. “and can catch fire in your garage, too.”

All Tesla fires have been concluded by the NHTSA to be caused by the electric vehicle's battery suffering some kind of trauma, sometimes by crashing at high speeds. In the Davie incident, the driver was going between 75 mph and 90 mph on a road with a 50-mph speed limit. The two teens who died in Fort Lauderdale were going 116 mph.

Spontaneous combustion in Tesla not a manufacturing defect !

"There are really only a few reasons why a lithium-ion battery catches on fire," Archer said. "Liquid, dead short," or, for every one battery cell in a billion, "spontaneous combustion."

In the Shanghai Tesla garage fire a damaged battery cell — whether the damage has been done by some kind of impact, water damage, or manufacturing defect — can go into "thermal runaway." That's when the temperature in the cell rapidly increases and then triggers the same reaction in another cell and another one after that. That is called "cellular propagation," and in some cases it manages to stop itself inside the battery.

NHTSA exonerates Tesla in battery fires and concludes driver error

Elon Musk complained of “double standard” on Twitter after a vehicle ignited on its own in Shanghai on April 21, saying that “over a million combustion engine car fires per year & thousands of deaths, but one Tesla car fire with no injuries gets biggest headlines.”

Fires are less frequent in Teslas and other Evs vs Gass Vehicles !!!

August 17th 2021

Tesla’s second annual Impact Report, released earlier this month, underscores a reality that can’t be emphasized enough: Electric car fires are rare.

The electric car maker notes, as CEO Elon Musk has for years, that the frequency of EV fire headlines can be deceiving. There were almost 190,000 vehicle fires in the U.S. in 2019, and they happen in gasoline vehicles at a much higher rate. It notes that from 2012 to 2020 there was about one Tesla vehicle fire per 205 million miles traveled—versus one per 19 million miles traveled for all types, citing data from the National Fire Protection Association (NFPA) and U.S. Department of Transportation.

“Due to this public misconception, we decided to start publishing vehicle fire data annually,” the company said.

In order to provide data that can be compared to that from the NFPA, Tesla says that its data set includes vehicle fires caused by structure fires, arson and other reasons unrelated to the vehicle, which it says “account for some of the Tesla vehicle fires over this time period.”

Tesla claims that when the media reports on a vehicle fire, it’s usually reporting on an EV fire. “This is likely a result of the novelty of EV technology, rather than the prevalence of EV-related fires compared to ICE vehicle-related fires,” it speculates.

The company however neglects to point out one likely reason for that “novelty”—that it’s the intensity and duration of EV fires that is so noteworthy. It’s also relatively rare to have a gasoline vehicle that hasn’t been driven suddenly catch fire in the middle of the night, during or after charging. And generally speaking, gasoline vehicle fires are infernos and they're over quick; they don't smolder for hours despite efforts to extinguish them.

Tesla pointed out that it makes detailed information about its vehicles available to first responders—something that the National Transportation Safety Board (NTSB) warned was insufficient earlier this year.

Looking at that specific subset of vehicle fires, the results are quite different. According to the Highway Loss Data Institute (HLDI), the research arm of the insurance-funded Insurance Institute for Highway Safety (IIHS), the Tesla Model S has a non-crash fire claim frequency of 1.7 and 2.0, respectively, for single-motor and dual-motor versions in terms of claims per 10,000 insured vehicle years. The Model X is at 2.2, and the Model 3 is at just 0.4.

For the Model S and Model X, that’s higher than the average non-crash fire claims of just 0.8 across all luxury, sports cars, and luxury SUVs.

To add another asterisk to those figures, they don’t differentiate between incidents that might have started with a home electrical issue or charging hardware.

Those HLDI figures, prepared for NHTSA, were last released in December 2019, including data through 2018. We’ve reached out to them to see if they’ve been updated since then and will update this piece if so.
