“Hybrid vehicle + kelsey ignition = deadly combination. We accidentally left our 2010 Lexus rx450h in the garage with the ignition on and turned in for the night. Since it is a hybrid, it makes no sound - even when running . So we were unaware the ignition was still on. Much later in the evening, after the battery had depleted, the gas engine came on, filling our garage with carbon monoxide. Had I not gone back out to retrieve something from the garage and noticed that by this time the car's gas engine was running, I likely wouldn't be writing this e-mail. …”
