Acura is recalling about 106,000 SUVs because an air conditioner pulley can fall off, creating a hazard for other motorists.
The Honda luxury brand says the recall covers 2014 and 2015 MDX SUVs.
The air conditioner clutch drive bolt can loosen or break, which could cause a pulley to fall under the vehicle.
Acura says no crashes or injuries have been reported. The problem was discovered through warranty claims.
Dealers will replace the bolt at no cost to owners. Acura says it will start notifying owners in late July.
