BMW M42016 · 3.0L Petrol

The same S55 crank-hub concern that affects F80 M3s also hangs over the F82/F83 M4, especially on tuned cars making repeated hard launches.

Stiff suspension, large wheels, and poor UK roads can leave M4s with worn dampers, noisy top mounts, or poor wheel alignment that chews through tyres.

The folding-roof M4 Convertible can suffer from blocked drains, wet boot electronics, or roof-cycle faults if the mechanism has been neglected.

Turbocharged M4s can lose coolant from expansion tanks, front coolers, or hoses. It is a common nuisance fault on hard-driven examples and should not be ignored.
