What Problems Does the 2004 Mazda RX-8 Have?
The most frequently reported problem for the 2004 Mazda RX-8, and RX-8s in general, centers around the RENESIS rotary engine. Apex seal failure is a significant concern, often leading to low compression and requiring engine rebuilds or replacement. This issue stems from the engine's design and lubrication system. Oil consumption is also common, requiring owners to check and top off oil frequently. Hot start problems, where the engine struggles to restart when warm, are another well-documented issue. Ignition coil failure is relatively common and can cause misfires and poor performance.
Recalls for the 2004 RX-8 have included issues related to fuel leakage and potential engine stalling. Owners should check with Mazda or the NHTSA to confirm if their specific vehicle was affected by any recalls and that the necessary repairs were performed. Long-term reliability is a major concern due to the rotary engine's inherent weaknesses. Proper maintenance, including frequent oil changes and pre-mixing oil into the fuel, can help prolong engine life, but rebuilds are often necessary at some point. Rust can also be a concern, especially in areas with harsh winters where road salt is used. While later model years saw some improvements, the core rotary engine issues persisted throughout the RX-8's production run.

While later model years saw some improvements, the core rotary engine issues persisted throughout the RX-8's production run.
How long will the 2004 Mazda RX-8 last?
A well-maintained 2004 Mazda RX-8 can potentially reach 100,000 to 150,000 miles before requiring a major engine overhaul, provided diligent maintenance is performed. However, many owners report engine rebuilds being necessary much sooner, sometimes as early as 60,000 miles, if maintenance is neglected. Long-term durability is heavily dependent on the owner's maintenance habits. Frequent oil changes (every 3,000 miles) with the correct type of oil, pre-mixing oil into the fuel, and avoiding short trips are crucial. The rotary engine's apex seals are the primary weak point, and their lifespan is significantly impacted by driving style and maintenance. Rust, particularly in areas with road salt, can also affect long-term durability.

This is a great car to drive. Black leather seats all around. Front bucket seats with built in heat for cold days. Has extra storage and plugs to charge up your phone even in the back seats. Has plenty of leg room and is a 4 door. This car is so smart, it'll tell you if your running low of air in the tires. All my friends like to drive it too.
Paul Rx8
This little coupe has great use due to 2+ 2 passengers abbility. Generous leg room for both frint and back passengers. Also has a good size boot.

My RX8 was one of the best cars I have ever owned, and the one I have owned the longest. It's fun to drive with quick pick-up and great handling. It looks cool and has been reliable.
Negative Owner Reviews
Ex RX-8 owner
I purchaed my 2004 Rx8 with 40K miles on it. It ran good for the first 6 months then there were one problem after another. Thought maybe I bought a lemon but there was always another RX8 at the repair shop when mine was there. I got rid of it when the 60K mile warrenty ran out.

Well what can I say, they don't call them rotary experiments for nothing. You will be lucky if you can get 60,000 miles out of the car. I am also very surprised on how slow they are. Mods will not do anything to this car, you will have to replace the whole engine. This car is the perfect example of all bark and no bite. If you are going for looks this car is okay I guess, but don't plan on racing it.
TJ
I bought my 2004 Yellow RX-8 in 2006 and have never truly been satisfied. I have had problem after problem. First less than a year of owning it I stall at a red light. Come to find out there is a recall on the engine. I am by no means a mechanic but things I have noticed are severe shaking when in idle, rapid changes in RPM's while in idle, and slow acceleration/clicking noice while accelerating. I would recommend having your oil changed more frequently than every 3,000 miles with this car. If going for looks, this car is great, everyone comments and gives compliments, as far as reliability, I would not recommend it to anyone...
What Technology & Safety Features are Included?
The 2004 Mazda RX-8 came with relatively basic built-in tech for its time. Standard features included an AM/FM radio with a CD player. Higher trims like the Grand Touring offered a Bose premium audio system with a subwoofer. There was no navigation system available from the factory in 2004. Driver-assistance features were limited compared to modern cars; there were no advanced features like lane departure warning or adaptive cruise control.
Safety features included standard front airbags, side airbags, and anti-lock brakes (ABS). Traction control was also standard. Vehicle Dynamic Control (VDC), Mazda's version of electronic stability control, was available as an option.
Crash-test ratings from the IIHS (Insurance Institute for Highway Safety) and NHTSA (National Highway Traffic Safety Administration) varied. The RX-8 generally performed well in frontal crash tests but had mixed results in side-impact tests. It's important to consult the specific ratings for the 2004 model year on the IIHS and NHTSA websites for detailed information. The available safety features were adequate for the time, but the RX-8 lacked the more advanced driver-assistance systems that are common in modern vehicles. The focus was more on the driving experience than cutting-edge technology.

2004 Mazda RX-8 Prices and Market Value
When new, the 2004 Mazda RX-8 had an MSRP ranging from approximately $27,000 to $32,000 depending on the trim level and options. Currently, used market prices typically range from $3,000 to $10,000, depending on condition, mileage, and maintenance history. The RX-8 has depreciated significantly due to its rotary engine's reputation for unreliability and the associated maintenance costs. Factors affecting resale value include engine health (compression test results are critical), overall condition, mileage, service records, and the presence of any modifications. Cars with documented maintenance and strong engine compression command higher prices.
2004 Mazda RX-8 Cost of Ownership
The 2004 Mazda RX-8 is generally considered a costly vehicle to own long-term. Insurance costs are moderate but can be higher for younger drivers due to its sports car classification. Fuel economy is poor for its size and performance. Maintenance and repair costs are significantly higher than average due to the complexities of the rotary engine and the potential for expensive repairs, particularly apex seal failure. Long-term ownership requires budgeting for potential engine rebuilds. It is not an economical choice.

How Does the 2004 Mazda RX-8 Compare to Other Coupe?
The 2004 Mazda RX-8 competed with cars like the Nissan 350Z, Honda S2000, and Subaru WRX. In terms of performance, the RX-8 offered unique handling and a high-revving engine, but it lacked the torque of the 350Z. The S2000 provided similar handling but with a more reliable engine. The WRX offered all-wheel drive and turbocharged power, making it a more practical choice for some.
In terms of features, the RX-8 was reasonably equipped, but the Nissan 350Z offered a more luxurious interior. Reliability is where the RX-8 fell short compared to its rivals. The 350Z and S2000 are known for their greater reliability. The WRX, while not as reliable as the Japanese sports cars, is easier and often cheaper to repair.
In terms of price, the RX-8 was competitive when new, but its rapid depreciation makes it attractive on the used market. However, potential buyers must factor in the higher maintenance costs. If reliability is a major concern, a Honda S2000 or a well-maintained Nissan 350Z would be better alternatives. If all-weather performance is a priority, the Subaru WRX is a compelling option.

Final Verdict: Is the 2004 Mazda RX-8 a Good Coupe?
The 2004 Mazda RX-8 is ideal for driving enthusiasts who appreciate unique engineering and are willing to accept the risks and responsibilities associated with a rotary engine. It's worth buying *if* you are mechanically inclined, can perform routine maintenance, and are prepared for potential engine repairs. It's best purchased used, given the significant depreciation. A well-maintained example with documented service history and strong engine compression is crucial. Avoid neglected or modified cars. The Shinka or Grand Touring trims offer more desirable features, but engine health should be the primary consideration. If you prioritize reliability and low running costs, look elsewhere; but if you crave a unique and engaging driving experience, the RX-8 can be rewarding.
