NHTSA complaint #11246041, filed 2019-08, 2,000 miles“Toyota Avalon hybrid with keyless ignition. Car is silent but may stay on when parked in garage. There is no warning sound or light if car is left on and car is silent, but as battery drains, the engine may come on 20 min later and generate carbon monoxide. I am an alert driver but this has happened twice. More than 17 Toyota owners have died of carbon monoxide poisoning. This is an easy software fix. Toyota says it will fix in 2020, but there is no software fix coming for hybrids already sold.”
