Since 2006, at least 28 deaths and 45 injuries have been linked to keyless engines that do not automatically shut off after the driver exits the car, even if the driver leaves with the fob required to activate the engine, a review by The New York Times found.
In each case, the driver was found to have inadvertently left the car running in a garage. Many keyless vehicles do not need the fob nearby to remain running. The error caused the attached homes to fill up with the exhaust’s toxic carbon monoxide gas, which is odorless and colorless.
In 2016, a similar review of car poisoning deaths by the nonprofit safety group KidsAndCars.org found that there were at least 20 deaths involving keyless ignitions from 2009 to 2016.
Almost half the fatalities and injuries reviewed by the Times involved Toyota models, including Lexus, a luxury vehicle division of Toyota.
In 2015 a class action lawsuit that was filed against 10 automakers cited 13 deaths that it said were caused by keyless ignitions. The lawsuit was dismissed in 2016 after a judge ruled that it’s only “speculative” that the keyless feature causes death or injury, Law360 reported.
