A small batch of inflators may have been improperly welded, potentially affecting deployment.

Fiat Chrysler Automobiles is preparing to recall a small batch of Jeep Cherokee crossovers to replace the knee airbags.

Some vehicles from the 2017 model year were assembled with a faulty driver's knee airbag. The airbag inflator, produced by ARC Automotive in Knoxville, may have been manufactured with an improper weld.

"The consequence of improper welds on the KAB inflator and potentially inadequate knee blocker cushion inflation is a potentially compromised safety system with possible additional injuries to the driver in certain types of vehicle crashes," FCA warns.

The campaign affects just 88 vehicles sold in the US market. Each will receive a new knee airbag to prevent failures.

FCA has not publicly cited any injuries related to the issue.
