The F80 M3's S55 twin-turbo inline-six is a potent performer, but early production engines (pre-mid-2017) suffered catastrophic rod bearing failures. Post-refresh cars improved significantly, though transmission coolers, crank hub issues, and driveline vibrations remain common headaches.
Connecting Rod Bearing Failure (Early Production)
Occasional · high severity
Typical onset: 30,000-60,000 mi
Symptoms: metallic knocking on cold start, low oil pressure warning, metal shavings in oil filter, sudden catastrophic failure with no warning in some cases
Fix: Full engine-out teardown, crank polishing or replacement, new bearings, typically 25-35 hours labor. Many owners preemptively upgrade bearings around 40k-50k. Post-July 2017 production has revised bearings and is significantly less affected.
Symptoms: sudden loss of power, check engine light with multiple misfires, accessory belt shredding, loud slapping noise from front of engine, oil leaking from front main seal area
Fix: Crank hub bolt stretches and allows harmonic balancer to walk forward, damaging front main seal and timing components. Requires engine-out service, crank inspection, new bolt and balancer, 20-30 hours. Preventive torque check at 30k recommended.
Estimated cost: $6,000-10,000
Transmission Oil Cooler Failure (ZF 8-Speed)
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: transmission slipping or harsh shifts, pink or milky transmission fluid, coolant loss with no external leaks, overheating under hard driving
Fix: Internal cooler develops leaks allowing coolant and ATF to mix. Requires cooler replacement, full trans fluid flush, sometimes radiator replacement if contaminated. 6-10 hours labor depending on additional cooling system damage.
Estimated cost: $1,800-3,500
Driveshaft Center Support Bearing / Guibo Failure
Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: clunking on acceleration or deceleration, vibration at highway speeds, visible rubber deterioration at flex disc, center bearing play or noise
Fix: Flex disc (guibo) and center support bearing wear prematurely under aggressive launches. Replace both as a set, 3-5 hours labor. Covered by a recall for some VINs, but many fall outside recall parameters.
Estimated cost: $800-1,500
Rear Subframe Mounting Point Cracking
Rare · high severity
Typical onset: 70,000-120,000 mi
Symptoms: clunking from rear on uneven roads, visible cracks at subframe mounts, unusual rear-end handling or instability, alignment issues that won't hold
Fix: Hard launches and track use can crack chassis mounting points. BMW issued a recall for inspection/reinforcement plates on some VINs. Repair requires subframe removal, welding reinforcements, realignment. 12-18 hours if welding needed.
Estimated cost: $2,500-5,000
Fuel Injector Carbon Buildup (Direct Injection)
Common · low severity
Typical onset: 50,000-80,000 mi
Symptoms: rough idle when cold, hesitation on light throttle, misfires under load, gradual power loss, fuel trim codes
Fix: DI engines have no fuel wash over intake valves. Walnut blasting intake valves every 50k-60k is recommended preventive maintenance. 4-6 hours labor, includes new gaskets and throttle body cleaning.
Estimated cost: $600-1,200
VANOS Solenoid Failure
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: rough idle, loss of power especially in midrange, check engine light with cam correlation codes, cold start rattle lasting more than 2-3 seconds
Fix: Solenoids fail or get clogged, typically both banks simultaneously. Replace both solenoids, clean screens, verify timing. 3-5 hours labor. Use OEM parts only—aftermarket fails quickly.
Estimated cost: $800-1,400
Owner tips
Check production date—cars built after July 2017 have updated rod bearings and are significantly more reliable
Send oil samples to Blackstone Labs every 5k miles to monitor bearing wear, especially on pre-refresh engines
Budget for walnut blasting intake valves every 50k-60k miles as preventive maintenance
Inspect crank hub bolt torque and driveshaft guibo at every major service—cheap insurance against expensive failures
Verify recall completion for driveshaft and subframe—some VINs eligible but not all owners were notified
Avoid extended oil change intervals—5k maximum with quality synthetic, preferably 10W-60 for track use
Check for full service history including transmission fluid changes at 40k-50k intervals
Buy a post-July 2017 car with documented maintenance and bearing checks; avoid early production unless engine has been rebuilt with updated parts—when maintained properly, it's one of the best-handling sedans ever built.

BMW of North America, LLC (BMW) is recalling certain 2016-2017 BMW M3 Sedans, 2016-2017 BMW M4 and M4 GTS Coupes and 2017 BMW M4 Convertible vehicles. The connection between the driveshaft and the flange may fail resulting in a loss of propulsion.
Consequence: A loss of vehicle propulsion can increase the risk of a crash.
Remedy: BMW will notify vehicle owners, and dealers will replace the driveshaft, free of charge. The recall began April 9, 2019. Owners may contact BMW customer service at 1-800-525-7417.

BMW North America, LLC (BMW) is recalling certain model year 2016 BMW M2 Coupe vehicles, 2015-2017 M3 Sedan vehicles and 2015-2016 M4 Coupe and M4 Convertible vehicles. During servicing of the rear differential for a prior service action, the rear sub-frame bolts may have been reused instead of being replaced. Reuse of the existing bolts may cause the bolts to loosen.
Consequence: Loose rear sub-frame bolts may adversely affect vehicle handling and control, increasing the risk of a crash.
Remedy: BMW will notify owners, and dealers will replace the rear sub-frame bolts with new bolts, free of charge. The recall began on November 3, 2016. Owners may contact BMW customer service at 1-800-525-7417.
