NHTSA banned the sale and import of DTN-marked air-bag inflaters in April after they were tied to at least 10 U.S. deaths and multiple severe injuries since 2023, exposing a gray-market supply chain that regulators say they cannot fully trace.

The National Highway Traffic Safety Administration in April banned the sale and import of air-bag inflaters bearing a part number linked to Chinese manufacturer Jilin Province Detiannuo Safety Technology, known as DTN Airbag, after the components were tied to at least 10 fatalities and three severe injuries in the U.S. since 2023, according to agency filings and a Wall Street Journal investigation.
"The worry here is that a bunch of consumers are going to unwittingly purchase bombs and put them in their steering columns," said Ellis Boyle, U.S. Attorney for the Eastern District of North Carolina, whose office prosecuted a case involving a state employee who sold roughly 3,000 counterfeit air-bag modules with DTN-marked inflaters.
The banned inflaters — a component that ignites and rapidly fills an air bag during a crash — were likely imported illegally into the U.S. and installed in aftermarket replacement air bags sold online through platforms including eBay and Facebook Marketplace, NHTSA said. The agency found that some inflaters entered the country concealed inside items such as toys and dollhouses, making them nearly impossible to track through normal customs channels. NHTSA Administrator Jonathan Morrison called the situation "unprecedented," noting that a traditional recall is unlikely because regulators cannot determine who imported and distributed the parts.
The deaths include a 22-year-old mother in Florida, a 17-year-old girl in Utah whose mother bought her the car for her birthday, a middle-school English teacher in Oklahoma, and a 20-year-old man in Mississippi. An autopsy report on an Arizona man who died in a crash noted a large metal shard in his neck inscribed with a DTN serial number. In June, a Florida jury awarded $603 million to the family of Destiny Byassee, the 22-year-old mother who died in 2023 after the air bag in her Chevrolet Malibu exploded during a crash. The vehicle had been repaired with a counterfeit air bag purchased on eBay for roughly $100 — one-tenth the cost of an authentic replacement, according to court records.
The Gray-Market Supply Chain
Counterfeit air bags have circulated in the U.S. for years, but the DTN-linked deaths mark the deadliest episode to date. Over a two-year period through spring 2024, Mateen Mohammad Alinaghian, a former North Carolina Department of Transportation employee, imported about 2,500 counterfeit air bags into Raleigh with fake logos of automakers including Chevrolet and Honda, then sold them on Facebook Marketplace. He was sentenced to a year and a day in prison.
DTN, which has 29 employees and produced 16,000 inflaters of various models last year, told NHTSA in April that it does not do business in the U.S. and believes the parts in question are counterfeits manufactured by another company. The agency acknowledged the counterfeit argument but proceeded with the ban, saying the parts are clearly defective regardless of origin.
NHTSA has sought information from eBay and Facebook owner Meta about their ability to police counterfeit air-bag sales. EBay said in a letter that courts have held it is not liable for defective products sold on its platform. Meta said it provides digital infrastructure for third-party listings but does not handle warehousing or delivery. Both companies said they are cooperating with the investigation.
What Drivers Face
The only way for drivers to know whether their vehicle contains a DTN-marked or counterfeit inflater is to pay a mechanic to inspect the air-bag module. NHTSA has created a dedicated webpage about the risk and is working with Carfax to allow car owners to check vehicle identification numbers for prior crash history that may have triggered air-bag deployment.
The agency's enforcement challenge reflects a broader gap in oversight of aftermarket auto parts. Roughly 4 million vehicles are recycled annually in the U.S. and Canada, generating more than $32 billion in recovered parts sales, according to the Automotive Recyclers Association. Unlike automaker-certified replacements, aftermarket air bags sold online face minimal regulatory scrutiny before reaching consumers.
"NHTSA investigators have been forced to play a game of whack-a-mole against a complex, gray-market supply chain," according to an internal January email reviewed by the Journal, in which an investigator wrote that predicting future rupture events "would be close to a wild guess as many of the factors cannot be determined."
