Even the 'newest' FD (1995 model) is now 22+ years old. ANY car this age will have problems but with the FD you have an increasing limited availability of OEM parts to keep it "like new".
Unique to the FD are problems associated with the 13BREW rotary engine. While extremely simple (3 moving parts - eccentric shaft and two rotors); the engine's main failure points are:
1. cooling system 'O'rings
2. apex seals on the rotors
These engines do not tolerate pre-detonation or "pinging"...at all. Not once. So it is critical to keep air-fuel ratios perfect. Lean out and you can go boom.
The sequential twin-turbo system is complex and subject to failures in the solenoids and rubber hoses.
The stock exhaust system retains an incredible amount of heat, especially the pre-cat unit. This heat contributes to extreme underhood temperatures and is the main cause of rubber hose failures.
With that said, a properly maintained and basically stock or lightly "modded" FD is extremely reliable and will give you years of fun, fun, fun. The links that 7 Rocket gave are the culmination of hundreds of thousands of man hours of experience and trial-and-error and real-world learning. Just a few 'reliability mods' will help insure your FD is running for another 25 years.
Those of us that have had our cars for 10, 15, 20 or more years are usually on our second (or more) engine, but have made all the necessary changes to insure far longer life than the Mazda engineers designed into the powertrain.
