Known issues on the 1991 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, causing improper retraction and inadequate occupant protection in a sudden stop or accident. The second covers the front safety belt buckle assembly: the red plastic "PRESS" release buttons can break, with pieces falling into the buckle and causing it to operate improperly, so the belt fails to provide adequate crash protection. Owners have filed 72 complaints for the year, and no technical service bulletins are logged for it. The factory diagnostic and repair procedures behind those systems are here.
Whether you're inspecting the front seat belt buckles, tracing webbing wear at the retractor, or working through a routine service interval, this manual keeps you on the correct OEM specification for your specific 1991 Sentra.
