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
My seatbelt motor and rail has a recall that the dealer confirmed it when I took it to them. My seatbelts get stuck sometimes causing safety concerns. The recall sent in 1996 from Mazda states the cable can wear sufficiently that the cable which retracts the buckle assembly will jam in the rail making it inoperative, if a collision the occupants will not be properly restrained.Recall states the dealer will extend warranty and replace shoulder belt rail and motor for the life of the vehicle. I took my car around October of 2021 they had the car and confirmed recall said they will call me when they get the parts, it’s September of 2022 and I haven’t gotten a call from them, when I call they tell me they don’t have them yet or say they know nothing regarding this car. Can someone help me to get this recall taken care of since I still own the car and have safety concerns with the seatbelts. Sometimes they get struck and don’t want to release properly.

AS I WAS DRIVING HOME ONE EVENING AT APPROXIMATELY 11:30PM IN MY 1991 MAZDA RX7, MY INTERIOR GAUGE LIGHTS SUDDENLY WENT OUT. I PULLED OVER TO CHECK THE OTHER LIGHTS ON THE OUTSIDE OF MY CAR. THE PARKING LIGHTS, TAIL LIGHTS AND ALL SIDE MARKER LIGHTS WERE NOT WORKING. I CHECKED FOR A BLOWN FUSE AND THE FUSE WAS OK. I HAVE TALKED WITH MY "MAZDA" MECHANIC AND HE SAID THAT HE HAS COME ACROSS MANY RX7'S THAT HAVE THE SAME PROBLEM.
