On the 2019-2020 BMW M2, the M2 Competition shares the S55 engine with M3/M4 and inherits the catastrophic crank hub failure issue. The crank hub (harmonic balancer) is press-fit onto the crankshaft and can slip under high load, especially with upgraded software or track use. When the hub slips, timing is lost and valves contact pistons, destroying the engine. This is the same critical failure point as the F80 M3 and F82 M4. The OEM crank hub has inadequate interference fit. Most failures occur on tuned cars or during hard track use between 30,000-70,000 miles.

This issue also affects: Buick Enclave, Buick Encore, Buick LaCrosse

Common Symptoms

Sudden catastrophic engine failure with no warning
Rough idle or vibration (early warning if hub is starting to slip)
Check engine light with timing correlation codes (P0016, P0017)
Misfire codes across all cylinders
Metal-on-metal noise from front of engine

How to Fix

MANDATORY preventive replacement with upgraded pinned or keyed crank hub. Pure Turbos, VTT, and S55 Crank Hub Fix all sell upgraded solutions with mechanical retention (pin or keyway). Installation requires crankshaft pulley removal and careful torque specs. This is considered essential maintenance for any S55-powered car, especially if tuned or tracked. Many M2 Competition owners perform this upgrade immediately after purchase.

On the 2016-2018 BMW M2 N55, the N55 engine in the F87 M2 (2016-2018) suffers from accelerated rod bearing wear, though not as catastrophic as the S65 V10. Track use, aggressive driving, and extended oil change intervals accelerate bearing wear. Tight bearing clearances and high cylinder pressures in the M-tuned N55 contribute to the issue. Symptoms typically appear after 60,000-80,000 miles or after multiple track days. Unlike M3/M5, most M2 owners catch this before complete failure, but preventive replacement is strongly recommended for track-driven cars.

This issue also affects: BMW 5 Series, BMW M4, BMW M5

Common Symptoms

Metallic knocking noise at idle (especially when warm)
Oil pressure fluctuation or low oil pressure warning
Metal particles visible in oil (send oil sample to Blackstone Labs)
Engine noise increases with RPM
Low oil pressure at hot idle (below 14 PSI)

How to Fix

Preventive rod bearing replacement recommended at 60,000 miles or before track use. Upgraded aftermarket bearings (ACL Race, King Racing) provide larger clearances and better durability. Oil analysis every 5,000 miles to monitor bearing wear (check for copper/lead particles). Use high-quality 5W-40 oil (Liqui Moly, Motul) and change every 5,000 miles max for track cars. Some track-focused owners replace bearings every 50,000 miles preventively.

On the 2016-2020 BMW M2, both the N55 (M2) and S55 (M2 Competition) engines use plastic charge pipes that fail under boost pressure and heat cycles. The charge pipe routes pressurized air from the turbocharger(s) to the engine intake. Plastic becomes brittle and cracks, especially on tuned cars running higher boost. Failure causes sudden loss of power and limp mode. The N55 has a single large charge pipe, while the S55 has multiple boost pipes that can fail. Aftermarket aluminum pipes are considered mandatory for any tuned M2.

This issue also affects: Audi A3, Audi A6, Audi A8

Common Symptoms

Sudden loss of power while driving
Loud hissing or whooshing sound from engine bay
Check engine light with boost pressure codes (P0299, P0234)
Limp mode activation
Visible crack in plastic charge pipe
Boost gauge shows loss of pressure (if equipped)

How to Fix

Replace with upgraded aluminum charge pipe. Popular brands: ARM Motorsports, VRSF, BMS (Burger Motorsport). Aluminum pipes eliminate the plastic failure point permanently and support higher boost levels for tuned cars. Install is straightforward DIY. For M2 Competition, also consider upgrading all boost pipes while engine bay is accessible. Many M2 owners install aluminum charge pipes preventively before failure.

On the 2016-2021 BMW M2, the 7-speed M-DCT dual-clutch transmission in F87 M2 models can develop mechatronics unit failures, causing harsh shifting, failure to engage gears, or transmission fault warnings. The issue is related to the solenoid pack and hydraulic valve body within the mechatronics sleeve.

This issue also affects: Acura TL, Acura CL, Acura ILX

Common Symptoms

Harsh or delayed shifts
Transmission malfunction warning
Failure to engage gear
Grinding noise during shifts
Limp mode activation
Check engine light
Jerking at low speeds

How to Fix

Replace or rebuild the mechatronics unit. In some cases, a transmission adaptation reset via ISTA can resolve early-stage symptoms. Severe cases require full mechatronics replacement, which involves dropping the transmission. Fluid change every 30k miles helps extend life.

On the 2016-2020 BMW M2, the Getrag DCT (dual-clutch transmission) in the M2 and M2 Competition experiences clutch pack wear from aggressive driving, launches, and track use. The DCT has two clutches (odd and even gears) that wear over time. Symptoms include shuddering during low-speed acceleration, rough shifting, and slipping under hard acceleration. Track use and repeated launch control engagements accelerate wear. DCT fluid degradation also contributes to poor shift quality. This transmission is shared with M3/M4 and has similar failure patterns.

This issue also affects: Acura TL, Acura CL, Acura ILX

Common Symptoms

Shuddering or judder when accelerating from a stop
Rough or harsh shifting between gears
Slipping sensation under hard acceleration
Burning smell from transmission
Check engine light with transmission codes
Clutch slip warnings on iDrive

How to Fix

Replace DCT clutch pack ($4,000-6,000 parts + labor). Change DCT fluid every 30,000 miles with BMW-approved fluid to extend clutch life. Avoid excessive launch control use. Transmission adaptation reset via BMW software often improves shift quality temporarily. Some performance shops offer upgraded clutch packs for track use. Extended warranty coverage highly recommended for DCT-equipped M2s.

On the 2016-2020 BMW M2 S55, the F87 M2 and M2 Competition have marginal cooling capacity for sustained track use. The small grilles and compact engine bay restrict airflow to the radiator, oil cooler, and intercooler. On track, oil temperatures commonly exceed 280°F and coolant temperatures spike, leading to heat soak and power loss. The M2 Competition with S55 engine runs even hotter. Extended track sessions can cause cooling system component failure or engine damage from overheating. This is well-documented on M2 track forums and affects all F87 M2 models when pushed hard.

This issue also affects: BMW M3, BMW M4

Common Symptoms

Oil temperature exceeding 280°F during track sessions
Coolant temperature warning on track
Noticeable power loss after 3-4 hot laps (heat soak)
Limp mode activation from overheating
Intercooler heat soak (reduced power on turbocharged models)
Fan running constantly after track session

How to Fix

Install aftermarket cooling upgrades for track use: CSF radiator (higher core density), aftermarket oil cooler (Mishimoto, CSF), upgraded intercooler (Wagner, CSF), and coolant reroute kit. Remove kidney grille blockage for better airflow. Install oil temperature and pressure gauges to monitor. Limit track sessions to 15-20 minutes with cool-down laps. Many serious track M2 owners install full cooling system upgrades ($2,500-4,000 total). For street use, stock cooling is adequate.
