The seat belt and seat anchoring bracket may have been improperly welded during production.
Polaris has issued a recall for the 2015-2018 Slingshot after discovering a problem with the seat assembly.
A bracket anchoring the seat belt and seat back may have been improperly welded and variations during assembly can prevent proper latching of the seat slider.
"If the seat slides unexpectedly, this may increase the risk of a loss of control or the risk of injury in the event of a crash," the company warns. "If the seat belt buckle and seat back dislodge from the seat base, this may increase the risk of injury in the event of a crash."
It is unclear if the issue is related to an NHTSA investigation involving fatal accident last year. A driver was ejected and killed after losing control and sliding sideways into oncoming traffic. The Slingshot's seatbelt retractor had shattered, allowing the belt to release during the crash.
The recall campaign affects around 24,000 vehicles sold in the US.
