1993 Mazda RX-7 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

What this page shows

Everything below is an owner-reported complaint submitted to NHTSA about the 1993 Mazda RX-7, 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.

NHTSA ID 10006667 · filed Dec 26, 2002

I NOTICED WHITE SMOKE COMING INTO THE CAR WHILE DRIVING TO WORK. I STOPPED THE CAR RIGHT AWAY AND OPENED THE HOOD TO SEE THE BACK OF THE ENGINE ON FIRE. I PUT THE FIRE OUT WITH A FIRE EXTINGUISHER AND HAD THE CAR TOWED TO A MAZDA ROTARY ENGINE SPECIALIST. I WAS INFORMED BY THE MECHANIC THAT THE FIRE WAS A RESULT OF THE FAULTY FACTORY FUEL LINE AND THE FUEL INJECTION SYSTEM, WHICH ARE A WELL KNOWN PROBLEM BY MAZDA MECHANICS. THE MECHANIC TOLD ME THAT THESE FIRES HAPPEN QUITE FREQUENTLY IN 1993-1996 RX-7'S AS WELL AS IN THE PRIOR BODY STYLE. I COULD HAVE BEEN SERIOUSLY INJURED FROM THIS INCIDENT, AND MY CAR NOW NEEDS OVER $3,000 WORTH OF REPAIRS, ALL DUE TO A KNOWN PROBLEM THAT HAS NEVER BEEN RECALLED. PLEASE HELP ME. DT
