Mazda Rx-8 problems

The Mazda RX-8 is a sports car manufactured by Japanese automobile manufacturer Mazda between 2003 and 2012. It was first shown in 2001 at the North American International Auto Show. It is the direct successor to the RX-7. Like its predecessors in the RX range, it is powered by a rotary Wankel engine. The RX-8 was available for the 2003 model year in most parts of the world.
The Mazda RX-8 utilizes a rotary Wankel engine, and the non-reciprocating piston engine uses a triangular rotor inside a near oval housing, producing from 141 kW (189 hp) and 164 lb⋅ft (222 N⋅m) of torque, to 177 kW (237 hp) and 159 lb⋅ft (216 N⋅m) of torque from launch. A myriad of various drivetrains are available in the Mazda RX-8.
The RX-8 was discontinued for the 2012 model year without a successor. It was removed earlier from the European market in 2010 after the car failed to meet emissions standards. Due to falling sales from Europe coupled with rising Yen prices, Mazda could not justify the continued sale of the RX-8 in other markets. 192,094 units were produced during its 9-year production run.

Common Mazda Rx-8 problems
The Mazda RX-8 is a four-door sports coupe known for its unique rotary engine and sleek design. However, it has been plagued with several common problems that have affected its reliability and overall owner satisfaction.
- Engine Problems: The Mazda RX-8's rotary-style engine is widely reported to be unreliable. The engine's check engine warning light on the dashboard is a key indicator of a faulty engine. Other common signs include a smoking exhaust, overheating, and poor fuel economy. The engine's susceptibility to problems increases once it reaches 60,000 miles, making it pricey to run.
- Power Steering Problems: Mazda RX-8 power steering problems have been reported by some owners, with the power steering going in and out randomly. This issue can be dangerous, especially at high speeds or in tight parking spots.
- Airbag Issues: The Mazda RX-8 has had airbag issues, with excessive pressure causing the inflator to rupture during airbag deployment, posing a risk of injury to occupants.
- Fuel Cap and Fuel Tank Problems: The Mazda RX-8 has had issues with fuel caps cracking and fuel tank caps loosening, leading to a risk of fuel loss and fire.
- Steering Problems: Steering issues have been reported in the Mazda RX-8, with cracks forming on the front lower transverse link socket, impairing steering.
- Catalytic Converter Failure: The Mazda RX-8's catalytic converter is prone to failure, which can be costly to replace. This issue is often caused by jumpy acceleration, which can damage the converter.
- Ignition Coil Failure: The Mazda RX-8's ignition coils can fail, particularly as the engine reaches the 30,000-mile mark, leading to engine problems and increased emissions.
In summary, the Mazda RX-8 has several common problems, including faulty starter motors, unreliable engines, power steering issues, airbag problems, fuel cap and fuel tank issues, steering problems, catalytic converter failure, and ignition coil failure. These issues have contributed to the car's poor reliability and high running costs, making it a less desirable choice for many car buyers.

One of the most reported RX8 problems revolves around its engine. Its unique high-performance rotary-style engine has proven to be more unreliable than expected, particularly after 60,000 miles.
What year Mazda RX-8 to avoid?
RX-8 Generations
The RX-8 has 2 generations, each with their own issues. Using the same PainRank™ system we've determined that you're better off avoiding the 1st generation (2004–2008).
Is a Mazda RX-8 a good car?
Mazda's design for the RX-8 was notable for its similarity to European coupes, a small yet potent sports car. But while its profile and power pleased many, the RX-8 proved to be a costly ride when it came to running costs, particularly at the pump.
How long will a RX-8 engine last?
It's no secret that the RX-8 has had a spotty record with engine life. While many have 100,000+ mile lifespan, far too many have gone far less. There is no single item that can be changed to double the engine life.

Mazda Rx-8 2004
- Date Of Incident: 2023-03-09
- Date Complaint: 2023-03-29
- VIN: JM1FE173440
- Components: ENGINE
- Summary: Engine naturally wears out especially after 200k miles due to friction in the natural design of the Rotary engine, resulting in losing its overall function such as turning off in the middle of a drive due to loss of compression from worn Apex Seals of the Rotary. The rotary engine requires a replacement of the Apex Seals to continue functioning normally to avoid any unpredictable accidents due to engine failure. An event occurred where my RX-8 went into limp mode in the middle of the freeway as i was commuting due a misfire from poor compression, this is more then likely a common event nowadays for RX-8 owners starting at the S1 2004 models with newer models soon to follow the same incident as me. This is completely unsafe especially traveling at 65 MPH

Ok, I purchased a 09 with 503 miles on it: Used. I guess a guy bought it for a month and traded it, so I ended up with great deal for 19k out the door. Besides price the car is basically a Mazda 3 with a very nice body style. Having owned a Mustang GT, Pontiac Grand Prix GXP, Maxima, G35 in recent years, this vehicle tops bang for the buck. Style is key since laser radar is everywhere now a days, but cruising in this is awesome. Smooth and you get plenty of looks, just don't race anyone unless you buy the higher end model. Interior is tight, drives on rails: reminds me of my G35. Reliability seems to be good, 95% of it is made in Japan.

Just bought this 2 weeks ago and have already put 1200km on it. The car is absolutely beautiful and amazing to drive. Handling is better than anything I have ever experienced and it has some get up and go once you hit the power band... all I can say is wow, thank you Mazda for this amazing car.

The 2009 RX8 is a fun car to drive, but it requires a certain level of commitment. If you're willing to drive it the way it's meant to be driven, you'll have a blast. However, keep in mind that the heavier your foot is, the more oil it consumes, and gas mileage is not great. Additionally, if you don't drive it hard, you risk flooding, fouling, and carbon build-up. I personally run mine hard all the time and still need to clean the spark plugs every 6,000 miles, but it's worth it for the driving experience. In terms of drivability, it's one of the best cars I've ever driven. The handling and forgiveness are great, and the top end is good too. The only downside is the lack of torque. As for comfort, the seats hold you in, but they are a little hard. Overall, the RX8 offers a lot of fun for your money, unless you're only interested in straight-line driving.

Vehicle year: 2007
I bought this car used with only 7500 miles on it. As of writing this, the car has just over 20k miles and I haven't had any reason to take it in for unscheduled visits to a mechanic. The best fuel mileage I got was 24.63mpg doing a constant 75mph on the freeway the day after I purchased the vehicle. However, daily commuting in traffic has resulted in 16-17mpg six months later. Compared to other vehicles in its class, it requires more attention on maintenance such as checking the oil level every other fill-up, premixing to preserve apex seals, and spark plug replacement should be more frequent than the manufacturer's specification. Despite these minor issues, I have thoroughly enjoyed my purchase. It's a very willing dance partner on a good road.

Hi there! I can totally relate to your love for the Miata - I've had 3 of them myself! However, with 3 kids, I had to let them go. That's why I switched to the RX-8, which still provides the same driving thrills but with the added bonus of being able to seat 4 people. It's perfect for picking up and dropping off the kids at school while still having fun driving. I know some people worry about rotary engine issues, but Mazda offers a 100K mile warranty on the engine, so there's really nothing to worry about. Sure, you might need to top off the oil every 2nd or 3rd fillup, but it's really not a big deal at all. In fact, it makes you feel more involved with your car! I do miss the convertible part of the Miata, but who knows - maybe Mazda will build a rotary Miata someday. Thanks for reading!

Hey there! I wanted to share my experience with my car. I bought it on a whim because it was so much fun to drive, without doing much research. After purchasing it, I spoke to several mechanics who told me that these rotary engines aren't the best. Unfortunately, my engine blew at 80k miles, but it lasted longer than most. Looking back, I can see that buying this car may not have been the best financial decision, but I still had a lot of fun with it!

Our vehicle seems to be using more oil than expected, about 1 quart every 600 miles. It's a bit frustrating, but we'll make sure to keep an eye on it. According to the manual, the oil should be changed every 5000 miles, but we've noticed it needs to be changed more frequently. We hope Mazda Corp can address this issue and improve their selling practices. Despite these challenges, we're still enjoying our car and its 15 mpg. It may not be the most fuel-efficient, but it gets the job done!

I have had a very negative experience with this car. Since purchasing it brand new in 2004, I have had to replace two engines and have encountered numerous other issues. The car frequently makes rattling noises and breaks down while I am driving, which is a serious safety concern. Unfortunately, the dealership has not been helpful and I have had to argue with them to get any assistance. While the car may look nice, it has been a constant source of problems and frustration.

Hi there! I noticed that you're interested in the '06 RX8 with the six-speed manual. I completely agree that the manual is the way to go, as it has more power (238hp and redlines 1500rpm higher) than the automatic. Before you make your purchase, there are a few things to keep in mind. Rotaries tend to consume more oil and gas than similar-sized piston engines, so be sure to check those levels often. While the standing-start acceleration may not be the most impressive, once you hit 30mph, get ready for an exciting ride! To get the best performance, make sure to rev the engine above 5000rpm. Also, be sure to run the car for at least 5 minutes to avoid flooding the engine. One thing that Mazda is known for is phenomenal handling, and the RX8 is no exception. Just keep in mind that this car isn't designed for snow or ice, so it's best to avoid driving in those conditions. Let me know if you have any other questions!

I purchased this stunning car brand new. Unfortunately, after only 20,000 miles, it had to be taken to the shop over 30 times. Even after a new engine was installed at 30,000 miles, the issues persisted. While it is undeniably a beautiful car, I cannot recommend it unless you are willing to spend a significant amount of money and not drive it often. Personally, I buy cars to drive them, not to keep them in the garage. I expected the car to have many more miles left in it at 30,000 miles. Regrettably, I had to get rid of it due to its unreliability, which cost me a total of 20 grand.
