2016 BMW M2 Problems: 9 Known Issues

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.

On the 2016 BMW M2 N55 3.0L turbo I6, bMW SIB 12 17 16 defines an F87 M2 path for vehicles produced through August 3, 2016 when a Drivetrain Malfunction message, reduced power and DME faults 120208 and 120408 occur. BMW identifies an overly sensitive DME diagnostic threshold that can switch off turbocharging-pressure control. The bulletin does not establish a cracked plastic charge pipe.

On the 2016-2018 BMW M2 N55B30T0, the N55 oil filter housing bolts to the side of the block and seals with a moulded silicone gasket. Heat cycling hardens and shrinks that gasket, and it starts weeping oil - a leak BMW inline-six owners see across the N52/N54/N55 family, commonly starting from roughly 45,000-60,000 miles. On the M2 it is significant beyond the mess: the housing sits above the accessory belt path, and oil contaminating the serpentine belt is the documented precursor to the N5x belt-ingestion failure, where a shredded belt is pulled past the front crank seal into the timing case. That turns a few-hundred-dollar gasket job into an engine-out repair. This is an F87 N55 issue; the S55 (M2 Competition/CS) has a different arrangement and is instead known for valve-cover leaks.

On the 2016-2018 BMW M2 N55B30T0, the 2016-2018 F87 M2 uses the N55B30T0 turbo inline-six, whose charge pipe (the boost tube from the intercooler outlet to the throttle body) is molded plastic. Under repeated boost cycling and underhood heat the plastic embrittles and either cracks at the elbow or blows the quick-disconnect coupler off entirely. On the M2 forums this is treated as a when-not-if item, and it happens more or less immediately once the car is tuned or running higher boost. The failure is instant and total: all boost pressure vents to atmosphere, the DME throws underboost/charge-air-pressure faults and puts the car in reduced power. It is not a safety recall item and BMW replaces it with the same plastic part under warranty.

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.

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.

On the 2016-2018 BMW M2 N55B30T0, the N55 uses an electrically driven coolant pump rather than a belt-driven one, and its brushless motor/control electronics are a known wear item across the N54/N55 family, with failures reported anywhere from roughly 30,000-40,000 miles to beyond 120,000 miles. When it fails there is no gradual warning - coolant circulation stops and the engine can reach overheat temperature within minutes of the warning appearing. The characteristic fault codes are 2E81 (electric coolant pump speed deviation) and 2E82 (electric coolant pump shutoff). The pump and the thermostat share the same housing location on the N55, so a pump failure frequently damages or disturbs the thermostat as well. This is distinct from the F87's track-use cooling capacity issue: this is an outright component failure that happens on street-driven cars.

On the 2016-2020 BMW M2, 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 received the M4 Competition cooling package (central radiator, two side radiators and an additional engine oil cooler) with larger grille openings to cope with its higher cooling demand. 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.

On the 2016-2021 BMW M2, the F87 M2 carries its rear differential on rubber mounts, and BMW's service bulletin SI B33 03 18 attributes a hard knocking noise from the rear axle during load reversals to the tuning of the rear differential suspension mount; from 7/2018 BMW's replacement part is a polyurethane mount. The signature symptom is a hard clunk or click from the rear when shifting between reverse and drive, when getting on and off the throttle, or at low-speed manoeuvring, sometimes with a droning vibration at cruise. BMW addressed the complaint through service information rather than a recall, and NHTSA holds a bulletin covering knocking noise and vibration/droning from the rear axle with instructions to replace the rear differential suspension mount. The complaint appears on both manual and DCT cars and is aggravated by track use and tuning.
