- What is wrong
- Residual engine heat can cause premature deterioration of the fuel hose causing the hose to leak. Also, removing and reinstalling the deteriorated fuel hoses increases the likelihood of a leak.
- Risk
- This condition can result in an engine compartment fire.
- Remedy
- Dealers will install an additional control unit for the electric cooling fan. The fan will then activate after the engine is turned off when the coolant exceeds a specified temperature. The fuel hoses will also be replaced with revised hoses.

Most recent owner complaints, unedited.
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

The lower intake manifolds supplied oem on these cars consistently fail. The material used by the manufacture has since changed to compensate for their mistake however, all of the owners of these cars are forced to pay the cost of repair for their poor design. At least 90% of these cars have had to have this part replaced and I am positive that that number will increase to 100% of the vehicles on the road. Some compensation should be made.
