The G80 M3 is BMW's most capable M3 to date, powered by the S58 twin-turbo 3.0-litre inline-six. Europe gets three combinations: 353 kW, 480 PS, with the six-speed manual and rear-wheel drive; 375 kW, 510 PS, with the eight-speed automatic and rear-wheel drive; and, from July 2024, 390 kW, 530 PS, with the eight-speed automatic and M xDrive. It addresses many of the F80's weak points — the crank hub issue is eliminated and the engine internals are reinforced. The ZF 8HP76 automatic is one of the best torque-converter gearboxes in production. Still relatively new, long-term data is accumulating but early indications are positive.· more· less

Buy if: You want the most refined and capable M3 yet and can budget for M-car maintenance costs and potential cooling system or brake module repairs.
Avoid if: You cannot absorb repair bills in the €1,500-3,000 range or want a car with decades of proven long-term reliability data.
Pumps in the cooling system degrade over time, risking overheating and a roadside breakdown · more· less
BMW's S58 technical manual describes a belt-driven mechanical main coolant pump plus separate electric pumps for the turbocharger and charge-air circuits, so this is not one electric unit doing everything. Specialists still recommend preventive replacement of the pumps around 80,000-100,000 km. The pump's plastic impeller can crack or deform under prolonged thermal stress, and the motor bearings can seize. Symptoms include fluctuating coolant temperature, coolant warning light, and a whining noise from the front of the engine. If the pump fails completely while driving, the engine can overheat within minutes, potentially warping the cylinder head. The auxiliary electric pumps can fail on their own, which is a different job from the belt-driven main pump. Replacement costs €1,200-1,800 at a specialist including parts and labor. Many owners choose to replace the pump proactively at around 80,000 km to avoid being stranded.
Carbon buildup on intake valves
up to €1,5002 of 7
Direct injection causes carbon deposits on valve backs, reducing performance over time · more· less
The S58 uses direct injection only, meaning no fuel washes over the intake valves during normal operation. Oil vapors from the crankcase ventilation system gradually deposit carbon on the valve stems and ports, restricting airflow and causing rough idle, reduced power, and occasional misfires. This is inherent to the design and affects all direct-injection engines to varying degrees. Walnut shell blasting is the standard cleaning method, typically needed every 60,000-80,000 km depending on driving style. Short trips and gentle driving accelerate buildup. Independent BMW specialists charge €800-1,000 for the procedure, while BMW dealers quote €1,200-1,500. Regular spirited driving at higher RPM helps slow the accumulation but cannot prevent it entirely.
Integrated Brake System (IBS) module failure
up to €4,0003 of 7
Brake-by-wire module can malfunction, reducing brake assist and triggering safety warnings · more· less
The G80 M3 uses BMW's integrated brake system which combines the brake booster, ABS module, and stability control into a single electronic unit. The often-quoted campaign is a US filing that names only five 2021 M3 and M3 Competition cars built 29 October to 6 November 2020, so it is not a general European action, and the other number quoted for it does not include the M3 at all and concerns signal disturbances inside the integrated brake system rather than an engine position sensor. While most affected cars are covered under recall, if the IBS module fails outside warranty coverage, replacement costs €2,500-4,000 at a dealer. Verify with BMW using the VIN that all brake system recalls have been completed.
iDrive 8 software glitches and screen blackouts
up to €3004 of 7
Infotainment screen randomly goes black, phone connectivity drops, stereo cuts out · more· less
This is the most commonly reported G80 M3 complaint and affects all iDrive 8 BMWs to some extent. Symptoms include the screen going completely black during driving, Bluetooth devices being forgotten, Apple CarPlay dropping out, and the stereo cutting out mid-playback. This concerns cars from July 2022, when BMW brought Operating System 8 and the Curved Display to the G80; earlier cars run the previous system. Most issues can be resolved by holding the volume knob for 30+ seconds to reset the system. BMW has released multiple software updates that improve stability. A dealer software update costs €150-200 if out of warranty, but some persistent cases have required replacement of the head unit wiring harness under a technical service bulletin. While annoying, this issue does not affect the car's mechanical function or safety systems.
S58 main bearing shell defect (built July to September 2021)
up to €5,0005 of 7
Manufacturing defect in main bearing shells on a limited number of model-year 2022 cars · more· less
BMW identified a manufacturing defect in the upper main bearing shells of certain S58 engines. Bulletin SIB 11 07 21 puts the delivery stop on model-year 2022 G80s built 13 July to 23 September 2021 rather than on early 2021 cars. The issue was significant enough to trigger a delivery stop and subsequent tech campaign. The repair involves dropping the oil pan and inspecting (and if needed replacing) up to 6 bearing shells — it does not require a full engine removal. BMW maintains a VIN-specific list of affected vehicles. Not every car on the list actually needs repair; BMW inspects first and only replaces bearings if wear is found. If caught early and performed under warranty or the tech campaign, the cost is zero. If the bearings fail on a car that missed the campaign, engine damage can require a rebuild costing €5,000+. This affects a very small number of cars from that build window.
Turbocharger wastegate or actuator wear
up to €4,0006 of 7
Wastegate components develop play at high mileage, causing inconsistent boost or rattle · more· less
The S58's twin-turbo system uses electronic wastegate actuators that can develop wear over time. Symptoms include a metallic rattle at partial throttle (2,000-3,000 rpm), inconsistent boost delivery, and potential limp mode under full-throttle acceleration. This typically manifests after 100,000+ km, particularly on cars that have been driven hard or tuned. If only the actuator or solenoid needs replacement, costs run €1,500-2,000. If turbocharger internals are damaged from prolonged overboost, a single turbo replacement costs approximately €2,000-2,500 per unit. Allowing the engine to idle briefly before shutdown after spirited driving helps preserve turbo life. For stock cars driven normally, this is an uncommon failure within the first 100,000 km.
Oil consumption above normal
up to €5007 of 7
Some owners report needing to top up oil between service intervals, especially after spirited driving · more· less
An estimated 15-20% of S58 owners report higher-than-expected oil consumption. BMW considers up to 0.7 litres per 1,000 km acceptable for high-performance engines, though most owners see significantly less under normal driving. Oil consumption increases notably during track use or sustained high-RPM driving, where oil temperatures can exceed 120 degrees Celsius. The S58 holds approximately 7 litres of oil. Monitoring the oil level regularly via the iDrive system is recommended. If consumption exceeds 1 litre per 1,000 km under normal driving, this may indicate valve stem seal wear or piston ring issues that should be investigated. For most owners, occasional top-ups between services are the only cost involved.
Strong engine, but cooling and brake electronics need watching
The S58 is widely considered BMW's best M engine in years, addressing the S55's crank hub weakness with a reinforced design and closed-deck block. Early reliability data is encouraging, with most owners reporting trouble-free ownership. The main concerns are the cooling system pumps, carbon buildup inherent to direct injection, and the integrated brake system module. The ZF 8HP automatic is one of the most proven gearboxes available. For a car of this performance level, the G80 M3 is surprisingly dependable when properly maintained.
Service history
Complete BMW dealer or authorized M specialist records essential. Verify oil changes at maximum 10,000 km intervals with BMW Longlife-01 FE specification oil.
Tires
Staggered setup, but the sizes follow the specification: European rear-wheel-drive cars are standard on 275/40R18 front and 285/35R19 rear, while 275/35R19 and 285/30R20 are standard on M xDrive and optional on rear-wheel drive. Check tread depth, date codes, and uneven wear. Rear tires wear faster, especially on RWD models.
Cold start
Start the engine completely cold. Listen for unusual rattling, knocking, or turbo whine in the first 30 seconds.
Test drive
Minimum 30 minutes including highway speeds and firm acceleration to bring engine, gearbox, and brakes fully up to temperature.
Specific for this vehicle
Check coolant level and water pump condition
Low coolant with no visible external leak warrants investigation. Ask whether the water pump has been replaced. Listen for whining from the front of the engine.
Verify all brake system recalls completed
Contact BMW with the VIN to confirm what applies to this car. Two US campaign numbers circulate widely for this car: the first covers five US cars built in late 2020, and the second does not include the M3.
Test iDrive system thoroughly
Navigate through all menus, test phone connectivity, Apple CarPlay, and media playback. Watch for screen blackouts or system restarts during the test drive.

Check for S58 main bearing campaign (model-year 2022 cars)
Cars built 13 July to 23 September 2021, sold as model-year 2022, may be affected by the main bearing shell tech campaign. Verify with BMW using the VIN whether the car was on the affected list and whether inspection or repair was completed.
Listen for turbo wastegate rattle at partial throttle
At steady 2,000-3,000 rpm under light load, listen for metallic rattling from the engine bay. Lift off the throttle gently and listen again.
Inspect for oil leaks underneath
Put the car on a lift or look underneath for any oil seepage around the valve covers, turbo oil lines, and engine-to-transmission junction.

Contact a BMW dealer with the VIN. The transmission item covers a one-week build window and the main bearing work is VIN-listed, so both are questions for the dealer rather than assumptions from the model year. Numbers that circulate but do not belong here: one is a US filing naming five cars built in late 2020, another does not include the M3, and BMW UK's Takata population covers models built between 1999 and 2018, which does not reach the G80.
Warranty Status
Factory warranty (3 years from Nov 2016, no km limit)Expired on 2021-2022 models, may apply to 2023+
Rust perforation warranty (12 years)Active on all G80 M3 models
BMW Extended WarrantyAvailable through BMW dealers for cars up to 10 years / 200,000 km
BMW offers a 3-year factory warranty (2+1 program since November 2016) with no kilometre limit. Early G80 M3 models (2021-2022) are now outside this period. Given the potential cost of IBS brake module replacement (€2,500-4,000) and water pump failure (€1,200-1,800), an extended warranty or dedicated repair fund is advisable for out-of-warranty cars.
