What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1991 Nissan 240SX, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Seat belts
Reports naming seat belts, buckles, retractors and pretensioners.
From owner reports, verbatim
TL* THE CONTACT OWNS 1991 NISSAN 240 SX. THE CONTACT STATED THAT THE SEAT BELT WAS INOPERABLE. HE CONTACTED A LOCAL DEALER AND THE MANUFACTURER AND THEY BOTH DIAGNOSED THAT THE CONTROL MODULE WOULD NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 190,000.
THE LAP BELT UNBUCKLES WHEN PRESSURE IS APPLIED SUCH AS HARD BRAKING WHERE THERE IS STRESS PLACED ON THE COUPLING. *MJS

Transmission
Reports naming the automatic or manual transmission, including shifting behaviour, shudder, slipping and transmission control modules.
From owner reports, verbatim
THE AUTOMATIC TRANSMISSION UNEXPECTEDLY STOPPED WORKING WHILE I WAS DRIVING THE VEHICLE. NO ACCIDENTS OR INJURIES RESULTED, BUT THIS COULD EASILY HAVE OCCURRED UNDER DIFFERENT CIRCMSTANCES. WHEN I BROUGHT THE VEHICLE TO A KNOWLEDGEABLE TRANSMISSION REPAIR SHOP, THE CHIEF MECHANIC INFORMED ME THAT THERE IS A KNOWN DESIGN FLAW IN THIS TRANSMISSION. IN FACT, HE HAD REBUILT MANY OF THESE AND KNEW HOW TO "MODIFY" THE UNIT TO PREVENT FURTHER PROBLEMS. MY QUESTION: DOESN'T THE MANUFACTURER HAVE SOME RESPONSIBILITY HERE? I AM IN THE PROCESS OF CONTACTING NISSAN AND WILL AWAIT THEIR FORMAL RESPONSE. IN THE MEANTIME, CAN YOU HELP ME GET THIS PROBLEM RESOLVED? I AM CONVINCED THERE ARE MANY MORE CONSUMERS OUT THERE DRIVING THESE VEHICLES WHO ARE AT RISK. *AK
TRANSMISSION WAS WASHED AND NOW TRANSMISSION WILL NOT SHIFT OUT OF 1ST. VEHICLE HAS SAT FOR OVER A WEEK AND STILL WILL NOT SHIFT OUT OF LOW WHEN IT IS IN DRIVE.

From owner reports, verbatim
NEED ALL INJECTORS TO BE REPLACED...WAS INFORMED THAT LEAKY INJECTORS MAY CAUSE FIRE. *AK

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
