The 2015 and 2016 BMW M4 share a platform, an engine, and a price range with the 2017. They don't share a reliability profile. NHTSA complaint filings drop from 21 on the 2016 to two on the 2017. The same engine, but with a critical revision to how the crank hub attaches to the crankshaft. A change made in March 2017 on the production line, not at a model year boundary.
That build date distinction is the most important fact in this guide. A 2016 M4 with the preventive crank hub fix documented in the service history is a better buy than an early-build 2017 that never had the car inspected. The door jamb sticker tells you the production month. The service records tell you what was done about it.
The F82 M4 is a legitimate driver's car. The S55 engine is one of BMW's best straight-sixes. The 6MT is a mechanical highlight. The DCT is quicker but riskier. The Competition package changes more than just the power number. This guide covers what separates a good F82 from a financial hazard.
This Generation at a Glance
The F82 M4 Coupe ran from 2015 through 2020 in the US market. The F83 M4 Convertible shared the same platform and powertrain. The F80 M3 Sedan — covered separately — uses the same S55 engine and has identical mechanical issues. This guide is coupe-focused, but the powertrain and inspection advice applies to all three body styles.
The generation splits into two distinct periods:
Pre-LCI (2015-2017): Halogen taillights, Fujitsu head unit on base trims, carbon fiber driveshaft on all variants.
Post-LCI (2018-2020): LED taillights, revised infotainment with Apple CarPlay on some trims, steel driveshaft replaced carbon (due to exhaust packaging requirements), updated interior trim. The LCI cars also lost some visual sharpness from the facelift according to longtime owners, but mechanically the 2018+ is the cleaner buy.
| Powertrain | Years Available | HP | Transmission | MPG (Combined) |
|---|---|---|---|---|
| M4 Coupe – 6MT | 2015–2020 | 425 hp | 6-speed manual | 20 (city/hwy: 17/26) |
| M4 Coupe – DCT | 2015–2020 | 425 hp | 7-speed DCT | 19 (city/hwy: 17/24) |
| M4 Competition – 6MT | 2017–2020 | 444 hp | 6-speed manual | 20 (city/hwy: 18/25) |
| M4 Competition – DCT | 2017–2020 | 444 hp | 7-speed DCT | 19 (city/hwy: 17/23) |

Powertrain and Trim Breakdown
S55 3.0L Twin-Turbo I6 — The Engine in Every F82
Every F82 M4 uses the same S55 B30 engine: a 3.0-liter twin-turbocharged inline-six producing 425 hp in base tune and 444 hp in Competition spec. The block is shared with the N55 but reworked significantly with stronger internals, individual throttle bodies, and higher compression. It's one of BMW's genuinely great M engines. It's also the engine with the crank hub problem.
The Crank Hub Issue
BMW's S55 secures the crank hub to the crankshaft with a single bolt and friction alone. No keyway. No roll pin. Just friction and torque. Under hard acceleration — especially the kickdown events that the DCT executes automatically — the hub can slip on the crank. Timing retards. The ECU logs a drivetrain fault. The dashboard lights up with an EML. In severe cases, the timing slips far enough that the pistons contact the valves. The engine does not survive that.
Cars produced before March 2017 carry this risk. The friction material used on those early builds was inadequate under sustained high-load use. BMW revised the specification in March 2017 without a formal recall.
The fix for pre-March 2017 cars is a preventive capture plate that pins the hub to the pulley assembly. Installing it before slippage occurs costs $800–1,500 in parts and labor and takes about a day. After slippage, the cost rises to $1,800–3,600 for full hub replacement and re-timing. After catastrophic failure, you're looking at an engine replacement or rebuild at $10,000–20,000 or more.
Forum consensus going back to 2016 on BimmerPost identifies manual transmission cars as significantly less prone to the issue. The DCT's automatic kickdown creates the exact loading condition that causes slippage — a sudden, unmodulated torque application the driver doesn't control. Manual drivers can manage throttle inputs to avoid that condition.
Before you buy any F82, check the production month on the door jamb sticker. If it's before March 2017, ask for documentation that the preventive capture plate has been installed. If the seller can't produce it, price the car assuming you'll have the work done.
Rod Bearings
The S55 rod bearing situation is less dramatic than the notorious S54, S65, and S85 failures in older M cars. Evolve Automotive tore down a 130,000-mile S55 and found bearings in serviceable condition. That said, preventive replacement every 50,000–60,000 miles is standard advice in the community, particularly for cars that see any track use. Symptoms of wear are engine knock at startup that persists after warmup, and metallic particles in the oil. Cost for preventive rod bearing replacement: $800–1,500.
Carbon Buildup
The S55 uses direct injection only — no port injection to clean intake valves. Carbon deposits build on the valve heads over time and restrict airflow. Walnut blasting the intake valves is recommended around 60,000–80,000 miles. Labor runs $400–800. Most high-mileage examples haven't had this done. Ask.
Oil Leaks
Valve cover gasket, oil filter housing gasket, and oil pan gasket are common failure points on higher-mileage S55 cars. A burning oil smell from the engine bay at operating temperature indicates an active leak onto the exhaust. Check around the valve covers and at the bottom of the engine before any purchase.
PCV Valve
The crankcase ventilation valve can fail on higher-mileage cars, causing oil consumption, vacuum leaks, and rough idle. It's an inexpensive part but requires partial engine disassembly to access. Budget $400–700 for parts and labor.
DCT (7-Speed Dual Clutch Transmission)
The DCT is quicker than the manual in every objective metric and more complex in every maintenance metric.
Common owner-reported issues: jerky shifts when cold, clunky engagement exiting reverse, clutch overheating under sustained aggressive driving. The mechatronic unit — the electronic control assembly for the transmission — is the expensive failure point. Repair runs $2,000–4,000. A full transmission rebuild costs $3,500–7,000.
DCT fluid needs to be changed every 30,000 miles or two years. Many owners skip it. Pull the dipstick on any DCT car you're considering and look for a metallic sheen in the fluid. That's transmission wear in progress.
The DCT also puts more stress on the crank hub than the manual. If you're buying a pre-March 2017 car with a DCT and no documentation of the preventive hub fix, walk away unless the price reflects the work needed.
Self-contained verdict: The F82 M4 DCT is the faster choice and the higher-maintenance choice. On a pre-2017 car, it's also the choice that creates maximum crank hub risk. If reliability matters more than lap times, the 6MT is the right answer.
6-Speed Manual Transmission
The manual is less common in the F82 than the DCT, which makes it more desirable to enthusiasts and harder to find. It's also more reliable. The clutch wears faster than a civilian car's under M-car driving — expect replacement around 60,000–80,000 miles on a car that's been driven spiritedly. Replacement cost: $1,500–2,500 parts and labor. The flywheel is a dual-mass unit that may need replacement at the same interval.
Testing for clutch wear: accelerate hard in third gear from 2,500 rpm. The car should pull cleanly without any RPM-vs-speed mismatch. Any slip indicates a clutch that's near the end of its life.
Competition Package
The Competition package is more than an advertising descriptor. It adds 19 hp over the standard M4, revised suspension with new springs, dampers, and anti-roll bars, adaptive M suspension as standard, and a re-tuned electronic differential and DSC calibration. The wheels are Style 666 — 19-inch front, 20-inch rear — derived from the M4 GTS. The ride is noticeably firmer. Many owners prefer it. Some find it too stiff for daily driving.
The Competition suspension revision makes the car handle differently enough that a pre-purchase drive in both variants is worthwhile if you have the option. The Competition's suspension tuning was also better-engineered for the power output — it's not just a cosmetic package.
Competition coupes command a $3,000–8,000 premium over equivalent standard M4s in the used market. The mechanical improvements justify it for drivers who push the car.
M4 CS (2018-2019)
The CS was a limited variant that sat between the Competition and the road-legal GTS. It added 9 hp over the Competition (453 hp total), shed roughly 130 lbs through carbon fiber body panels, a fixed carbon roof, bucket seats, and deleted rear seats. It used the GTS-derived front splitter and rear diffuser. Used prices in 2026 run $65,000–95,000 for clean examples. It's a special car for a specific buyer. The powertrain and engine issues are identical to the standard Competition.
M4 GTS (2016)
Approximately 700 built for the US market. Water injection, 500 hp, roll cage-ready interior, fixed rear wing, $134,000 new. Used examples now ask $90,000–140,000+. Not a daily driver. Mechanical issues mirror the standard S55 but with additional complexity from the water injection system. Out of scope for most used car buyers; mentioned for completeness.
Trim-Specific Notes
The base M4 and the Competition both come in Coupe (F82) or Convertible (F83). The convertible adds roughly 200–250 lbs over the coupe and has slightly different structural rigidity. Convertible prices typically sit $3,000–6,000 above comparable coupes in the used market. The added weight is measurable but not dramatic.
The M4 has no four-cylinder or hybrid option. Every car is the same engine. Trim selection (base vs. Competition) and transmission (6MT vs. DCT) are the two decisions that matter most for the ownership experience.
Options worth paying up for:
- Executive Package (2015-2017): Adds adaptive cruise control, surround view camera, heated steering wheel
- M Driver's Package: Removes the 155 mph speed limiter (available as standalone option)
- Adaptive suspension on standard M4: Only standard on Competition; worth adding on base if you can find it
Options that add cost without proportional value:
- Individual paint colors: Adds $3,000–6,000 new, doesn't recover that premium used
- Carbon ceramic brakes (optional CCMR): $8,000 new, impressive at track but overkill for street. Servicing them costs more and they're cold-weather sensitive.
Which Model Years to Target Within This Gen
| Year | Recalls | Key Facts | Verdict |
|---|---|---|---|
| 2015 | 3 | First year. Three recalls. Highest crank hub risk. Pre-LCI. | Caution |
| 2016 | 3 | 21 NHTSA complaints (peak). Two driveshaft recalls. Competition package arrives. | Caution |
| 2017 | 2 | Post-March 2017 build: crank hub revised. Pre-LCI styling. Driveshaft recall covers some build dates. | Good (check build date) |
| 2018 | 1 | LCI refresh. Steel driveshaft. LED taillights. CS model introduced. | Best value |
| 2019 | 0 | Competition package standard on many trims. Zero recorded NHTSA complaints. | Best overall |
| 2020 | 2 | Final year. Fuel injection recall (20V666) on some builds. Clean examples on market. | Good |
The sweet spot: 2018 and 2019 M4 Competition with DCT or 6MT. The 2018 eliminated the carbon fiber driveshaft issues. The 2019 recorded zero NHTSA complaints. Both carry the post-March 2017 revised crank hub. Prices for a clean 2018 Competition coupe with the DCT run $42,000–58,000.
Avoid: Any 2015 or 2016 with a DCT that has no documentation of crank hub preventive work. The combination of pre-revision hub and DCT kick-down is the highest-risk scenario.
Pre-Purchase Inspection Checklist
Before you touch the car:
- Note the production date on the door jamb sticker. Anything before March 2017 requires documented crank hub preventive work.
- Run the VIN through recall lookup. Verify recalls 15V782000 (driveshaft grease), 16V653000 (frame/members), and 18V713000 (driveshaft flange) are marked complete on any 2015-2017 car. The 2018V713 recall affects 2016-2017 production dates specifically March through September 2016.
- Pull the service history. Oil change intervals matter. M cars need oil changes every 5,000-7,500 miles, not the BMW Condition Based Service interval of 15,000 miles that the computer often shows. Evidence of 12,000-15,000-mile oil changes is a red flag.
Cold start inspection:
- Start the engine cold. A brief VANOS rattle that clears within 30 seconds is acceptable. A rattle that persists past warmup indicates VANOS wear or low oil pressure issues.
- Listen for a metallic tick at idle that follows RPM changes. That's different from VANOS and points to crank hub movement or valve train issues. Have a specialist check before proceeding.
- Look for white or blue smoke from the exhaust at startup. Blue smoke at startup = oil burning. White smoke under hard acceleration then lift-off = turbo seal issue.
For DCT cars:
- Warm the transmission to full operating temperature (20+ minutes of driving).
- In a parking lot, cycle repeatedly between drive and reverse. Note any clunks, delays over 1.5 seconds, or rough engagements.
- Check the DCT fluid dipstick for metallic sheen. If it's metallic, the transmission has seen wear. Budget $400-600 for fluid service minimum, more if the fluid indicates internal debris.
- Ask specifically whether DCT fluid has been changed. If never, or beyond 40,000 miles, add $400-600 to your offer as a negotiating point.
For 6MT cars:
- Hard accelerate in third gear from 2,500 rpm. Any engine RPM rising faster than vehicle speed indicates clutch slip.
- Test every gear for clean engagement. Grinding into second or fourth with aggressive shifts may indicate synchro wear from track abuse.
Engine bay walkthrough:
- Check coolant expansion tank: level between MIN and MAX when cold, clear amber/green color. Brown or milky coolant means oil contamination. That's a head gasket or oil cooler issue.
- Squeeze the charge pipes (the rubber/silicone pipes connecting intercoolers to the throttle body). Cracks or softness are early signs of failure.
- Look at the valve cover perimeter and oil pan for seepage. A damp, oily residue is normal on older cars. Dripping or pooling is not.
- Check oil condition on the dipstick. Black with metallic glitter? Rod bearing wear in progress.
Ask these questions:
- Has the crank hub preventive capture plate been installed? Any specialty BMW shop did this work will have an invoice.
- Has walnut blasting been performed? Important for any car above 60,000 miles.
- Has the car been tuned? Avoid tuned cars unless you can verify the tune was done at stock power and the crank hub work was completed before tuning.
- Has the car been on track? Track use accelerates wear on clutch, brakes, tires, cooling system, and rod bearings.
Running Costs
| Item | Standard M4 | M4 Competition | Notes |
|---|---|---|---|
| Combined MPG | 19-20 | 19-20 | 91 octane minimum, 93 recommended |
| Oil change | $150–250 (dealer) | $150–250 (dealer) | Every 5,000-7,500 miles recommended |
| Spark plugs | $300–500 | $300–500 | Every 30,000 miles |
| Brake pads (all four) | $500–1,200 | $500–1,200 | Rear wears faster; track use dramatically shortens interval |
| DCT fluid (if applicable) | $400–600 | $400–600 | Every 30,000 mi / 2 years |
| Carbon walnut blast | $400–800 | $400–800 | Once, around 60k-80k miles |
| Rod bearing inspection | $400–700 | $400–700 | At 50,000 miles, every 30k after |
| Est. annual repair cost | $1,500–3,500 | $1,500–3,500 | Excludes major repairs |
Major repair reserve to keep in mind: The crank hub fix ($800-3,600 depending on whether it's preventive or post-slip), a DCT mechatronic rebuild ($2,000-4,000), or a valve cover gasket ($600-1,200 with labor) can hit in any given year. Budget $3,000-5,000 in reserve for unexpected repairs and you'll be less surprised.
FAQ
Is the BMW M4 F82 reliable? At stock power with disciplined maintenance, the S55 is a capable engine that regularly crosses 100,000 miles without catastrophic failure. The highest-risk scenario is a pre-March 2017 DCT car with no crank hub preventive work and extended oil change intervals. Avoid that combination and reliability improves significantly.
What year BMW M4 F82 should I avoid? The 2015 and 2016 model years carry the most risk due to first-year issues, three recalls each, peak NHTSA complaints (12 and 21 respectively), and pre-revision crank hub specification. A 2015 or 2016 with complete service records, documented crank hub fix, and verified recalls can still be a good buy — just at a discount that reflects the work needed.
Is the BMW M4 F82 manual or DCT more reliable? Manual transmission cars are more reliable. The 6MT has no mechatronic unit to fail and is less prone to the crank hub slippage issue. The DCT is quicker but requires more maintenance and creates higher crank hub stress on pre-March 2017 cars. Forum consensus on BimmerPost has favored the manual for reliability since 2016.
Does the BMW M4 F82 have a rod bearing problem? The S55's rod bearing situation is less severe than the S65 (E90 M3) or S85 (E60 M5). A 130,000-mile S55 teardown by Evolve Automotive found serviceable bearings. Preventive replacement at 50,000-60,000 miles is widely recommended for peace of mind, especially for tracked cars, and costs $800-1,500. It's not the catastrophic failure risk that older BMW M engines carried.
How many miles do BMW M4 F82s last? Well-maintained F82s with stock power and regular oil changes regularly reach 120,000-150,000 miles without major engine failures. The limiting factors are typically maintenance neglect, crank hub issues on early cars, and DCT wear on high-mileage examples. Cars with documented service history, no track abuse, and verified crank hub preventive work are the long-mileage candidates.
Bottom Line
The 2018 or 2019 M4 Competition is the sweet spot in this generation. The 2018 LCI eliminated the carbon fiber driveshaft recalls that hit 2015-2017 cars, carries the post-March 2017 revised crank hub, and added Apple CarPlay. The 2019 recorded zero NHTSA complaints for the year. Either year in Competition trim with either transmission is a driver's car that rewards maintenance.
The one thing to always check: production date on the door jamb sticker, then service records for crank hub preventive work. A 2015 with the hub fix documented is safer than a 2017 that's never been inspected.
