Known issues on the 1990 240SX. One recall is on federal record for this model year, covering the front seat belt buckle assemblies: the red plastic "PRESS" release buttons can break, and the broken pieces can fall into the buckle assembly and keep it from latching or releasing properly, so the belt fails to protect the occupant in a crash. Owners have filed 47 complaints for the year. The factory diagnostic and repair procedures behind that system are here.
From a seat belt buckle inspection to a full KA24E tune-up, it keeps you on the OEM procedure and the correct specification for your specific 1990 240SX.
