Known issues on the 1990 Sentra. Two recalls are on federal record for this model year. The first covers the shoulder safety belt webbing, which can fray near the retractor due to improper belt guide performance, leading to improper belt retraction and inadequate occupant protection in a sudden stop or accident. The second covers the front safety belt buckle assembly, where the red plastic release buttons marked "PRESS" can break and shed pieces into the buckle, causing it to operate improperly and leaving the belt unable to adequately protect an occupant in a crash. Owners have filed 41 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From a front or rear seat belt inspection to routine engine service on the GA16I four-cylinder, it keeps you on the OEM procedure and the correct specification for your specific 1990 Sentra.
