NYT: 28 people killed by carbon monoxide after leaving on keyless cars

Drivers of keyless cars may want to be a little more cautious.

A report from the New York Times found that dozens of people have been poisoned by carbon monoxide after failing to shut off the keyless ignition on their vehicles.

Since 2006, the Times reports at least 28 people have died and 45 others have suffered injuries from the gas after it seeped into their homes.

Keyless ignition allows drivers to start their cars with the press of a button while an electronic key fob remains in their pocket or purse.

But some people wrongfully assume the car turns itself off when you exit, not realizing they need to press the button again.
