How often do garaged ICE vehicles catch fire. Ever?
It happens. Search https://abcnews.go.com/US/mysterious-bmw-fires-continue-calls-investigation-grow/story?id=60843215 for garage.
The above story was from Feb 2019. It says:
The luxury automaker wasn't the only vehicle producer to take that step. Car manufacturers collectively have issued 62 parked-car-fire-related recalls since 2017. Just last month, for example, Hyundai and Kia recalled 168,000 vehicles for fire risk.

It also says "Two weeks ago, Hyundai and Kia alerted the U.S. National Highway Traffic Safety Administration about a rare but dangerous defect discovered in 10 Hyundai Elantras that caught fire while parked and off.".

Still, the coverage of EV fires may be overblown, said Sam Abuelsamid, lead auto analyst for Guidehouse Insights. Seven Chevy Bolts have caught fire, or about 0.006 percent of those on the road. By comparison, the National Fire Protection Association said 212,000 gas and diesel vehicles caught fire in 2018, or about 0.07 percent of those on U.S. roads.
“Yes, we’ve seen some battery fires, but the numbers are small, and they need to be put into perspective,” Abuelsamid said.
It's actually about 20 Bolts (possibly a couple more) that have sustained battery fires. The other number probably comes from page 2 of https://www.nfpa.org/-/media/Files/News-and-Research/Fire-statistics-and-reports/US-Fire-Problem/osvehiclefires.pdf.
20 / 140,000 * 100 = 0.014% <-- % of Bolts worldwide that have had battery fire since Bolt was began shipping in Dec 2016.
212,500 / 290,000,000 * 100 = 0.07% <-- % of highway vehicles that catch fire in a single year in the US
