Dozens of people have been poisoned by carbon monoxide after not being able to turn off the keyless ignition car, according to the New York Times.
Its report found that 28 people were killed and 45 others had suffered injuries from the year 2006.
More than half of the 17 million vehicles sold annually in the united states now have keyless ignition.
The Society of Automotive Engineers (SAE) said that he had published safety recommendations in 2011.
“Our standards are of a voluntary nature. Corresponds to the manufacturers to use them when it is necessary”, said the director of the SAE’s Jack Pokrzywa.
It is difficult to put figures on the exact number of deaths related to carbon monoxide keyless ignition left running as no central records of the agency.

A spokesman for Toyota told the BBC: “Customer safety is always our top priority, and the Toyota Smart Key System has been, and continues to meet or exceed all relevant safety standards.”
In 2015 a group lawsuit was filed in the US against 10 of the world’s largest manufacturers of automobiles in the issue, which described the technology as “deadly”. The case was dismissed by a judge, the following year.
