The 2010 RX-8 is Mazda's last mass-production rotary sports car, powered by the 1.3L Renesis 13B twin-rotor engine. While characterful and fun, it demands meticulous maintenance and suffers from inherent rotary engine wear issues that can make ownership expensive past 60,000 miles.
Apex Seal and Rotor Housing Wear Leading to Engine Rebuild
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Hard starting, especially when hot, Loss of compression (below 6.5 kg/cm² per rotor face), Excessive oil consumption (more than 1 quart per 500 miles), Rough idle and poor low-end power, White or blue smoke from exhaust on startup
Fix: Complete engine rebuild or reman replacement required. Apex seals wear prematurely if owner doesn't let engine warm fully or revs below 3,000 rpm constantly. Carbon buildup accelerates wear. Rebuild includes new apex seals, side seals, rotor housings if scored. 16-24 labor hours for removal, rebuild, reinstall.
Estimated cost: $4,000-7,000
Ignition Coil and Spark Plug Fouling
Common · medium severity
Typical onset: 30,000-60,000 mi
Symptoms: Misfires and CEL with codes P0300-P0302, Flooding after short trips or failed hot starts, Hesitation under acceleration, Difficulty starting after sitting
Fix: Rotary engines run rich and carbon-foul plugs quickly. Leading and trailing coils also fail frequently due to heat. Replace all four coils and plugs as a set every 30k miles preventively. 2-3 hours labor. Use OEM Mazda coils—aftermarket units fail within months.
Estimated cost: $600-900
Catalytic Converter Failure from Oil Ingestion
Common · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: CEL with P0420 catalyst efficiency code, Rattling from underneath at idle, Loss of power and poor fuel economy, Sulfur smell from exhaust
Fix: Rotary engines inject oil into combustion chamber by design, which eventually clogs and destroys the cat. Requires OEM or high-flow aftermarket replacement. 3-4 hours labor. Often discovered when diagnosing rough running—check cat before condemning engine.
Estimated cost: $800-1,500
Engine Flooding from Short Trips
Common · medium severity
Symptoms: Cranks but won't start after being shut off cold, Strong fuel smell from exhaust, Wet spark plugs after failed start attempts, Happens after moving car short distance in driveway/parking
Fix: Rotaries flood easily if shut down before reaching full operating temp. Deflood procedure: remove fuel pump fuse, hold throttle wide open, crank 8-10 seconds. Replace plugs if saturated. Prevention: never shut off until coolant reaches 180°F+. 1 hour labor if plugs need replacement.
Estimated cost: $100-200
Oil Metering Pump Failure or Lines Clogged
Occasional · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Accelerated apex seal wear, Low oil level without visible leaks, Rough running and loss of power, Carbon buildup visible in intake ports
Fix: OMP injects 2-stroke oil into combustion chambers for apex seal lubrication. When it fails or lines clog, seals wear catastrophically fast. Test OMP flow at throttle body ports. Replacement involves manifold removal. 4-5 hours labor. Some owners premix 2-stroke in fuel as insurance.
Estimated cost: $800-1,200
Starter Motor Failure from Heat Soak
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Slow cranking or clicking when hot, Starts fine cold, fails after heat-soaking, Grinding noise during engagement, Intermittent no-start after shutting off hot
Fix: Starter mounted close to exhaust manifold and heat-soaks after shutdown. Fails more often than typical cars. Requires replacement, not rebuild. 2-3 hours labor—tight access under intake manifold area. Upgrade to gear-reduction style helps longevity.
Estimated cost: $500-800
Transmission Oil Cooler Line Leaks
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Red fluid puddles under engine bay, Transmission slipping or delayed engagement when hot, Low ATF level on dipstick, Lines corroded or cracked at fittings
Fix: External cooler lines for 6-speed auto rot at connections. Manual transmission doesn't have this issue. Replace lines and top off fluid. 1.5-2 hours labor. Check whenever doing spark plugs—easy to spot early.
Estimated cost: $300-500
Owner tips
Check compression at pre-purchase—each rotor face should be 6.7-8.5 kg/cm² and within 10% of each other. Below 6.5 means rebuild imminent.
Never shut off engine cold. Always warm to full operating temp (5-10 min minimum) and cool down after hard driving.
Run engine to redline at least once per drive to burn carbon. Rotaries need high RPM to stay clean.
Premix 4 oz of 2-stroke oil per tank as insurance against OMP failure—many enthusiasts do this religiously.
Replace coils and plugs every 30k miles preventively. Use only OEM Mazda coils.
Check oil every fillup—these engines consume oil by design. Top off with 5W-20 or 5W-30, keep above halfway mark.
Buy only if you're a rotary enthusiast willing to do frequent maintenance and accept a likely engine rebuild before 100k miles—budget $5k+ for that inevitability.

Consequence: A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy: Dealers will install new fuel pump mounting rings. Dealers will also add a thermal insulation pad to the fuel tank on RX-8 vehicles. Repairs will be performed free of charge. Owner notification letters were mailed November 17, 2021. Owners may contact Mazda customer service at 1-800-222-5500, Option 4. Mazda's number for this recall is 5121I.
AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE · 19V488000
2019-06-24 · EA15001
Mazda North American Operations (Mazda) is recalling certain 2010-2011 Mazda RX-8 vehicles that were previously recalled under recall 18V-716 but have not yet been repaired.
These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Owners are advised not to drive their vehicles until the repair has been performed. Mazda will notify owners, and dealers will replace the front passenger air bag inflator with an alternate one, free of charge. The recall began July 9, 2019. Owners may contact Mazda customer service at 1-800-222-5500, option 4. Mazda's number for this recall is 2618F.
