Bmw 4 Series years to avoid BMW 3 Saloon (F30, F80) (03.2011 - 10.2018)

Thinking about getting a BMW 4 Series? Sweet ride, but like any beauty, some model years have had their drama queens of issues.

The models to be a bit cautious about tend to be the earliest ones, especially 2014 and 2015. These years, especially the 428i with the N20 engine, are notorious for timing chain issues that can cause major engine damage if ignored. Owners have reported rattling noises on cold starts and sometimes costly repairs to fix what BMW eventually updated in parts only after early 2015.

Other common headaches across 2014 to 2017 include oil and coolant leaks (rubber gaskets and seals taking a hit), faulty high-pressure fuel pumps especially on turbocharged engines, and some finicky electrical issues with sensors and infotainment freezing. The 2017 model also missed out on some tech upgrades and Apple CarPlay, which might feel a bit dated now.

The 2021 model (first year of the newer G42 generation) brought teething issues such as electric power steering faults and less impressive interior tech, with some owners noting steering quirks at speed.

On the plus side, the more recent models from 2018 onward, especially 2019, 2020, and 2023, have generally improved reliability and better tech overall. But keep in mind that BMW repairs can get pricey, so always a smart move to get a thorough pre-buy inspection.

So, quick advice: steer clear of the early years 2014-2015 due to timing chain and engine problems, be cautious with 2017 and 2021 for tech and steering quirks, and look towards later models for a smoother and more reliable ride. Think of it like dating — avoid the drama-filled years unless you're ready for the commitment (and the repair bills).
