BMW Série 4 F32/F36 (2013–2020) (2013 – 2020)

Reliability score : 7.8/10

The BMW 4 Series F32 (Coupe) and F36 (Gran Coupe) represents the first generation of the 4 Series, marking the separation of coupes and convertibles from the 3 Series. Launched in 2013, it is based on the F30 3 Series platform, but with a lower, wider chassis and specific suspension settings for increased driving dynamics. The Coupe (F32) and Convertible (F33) were followed by the Gran Coupe (F36) in 2014, a four-door sedan with a coupe profile and a practical tailgate. A minor facelift (LCI - Life Cycle Impulse) occurred in 2017, bringing minor aesthetic touches, technological improvements, and an engine update (transition from Nxx to Bxx engines). The 4 Series F32/F36 is renowned for its balance of sportiness, comfort, and build quality, offering a typical BMW driving experience. Overall

✅ Strengths

Exceptional driving dynamics (chassis, steering)
Quality of interior finish and materials
Wide choice of powerful and efficient engines (especially B-series)
Elegant and timeless design (Coupe and Gran Coupe)
Comfort on long journeys (except for overly firm M Sport suspensions)
Highly successful ZF 8HP automatic gearbox

⚠️ Weaknesses

Reliability of N20/N26 (timing chain) and N47 (timing chain, EGR) engines on early models
Cost of options and maintenance at BMW
M Sport suspension sometimes too firm on degraded roads
Limited rear passenger space on the Coupe (F32)
Rear visibility on the Gran Coupe (F36) and Coupe (F32)
Oil leak issues on N20/N55 engines

🎯 Verdict

The BMW 4 Series F32/F36 is an excellent choice for those looking for a car that is elegant, powerful, and enjoyable to drive. Reliability is generally good, but it depends heavily on the engine and production year. For a confident purchase: * Prioritize post-LCI models (from 2017 onwards) equipped with B-series engines (B48, B58, B47, B57). These engines are considered very reliable and offer an excellent compromise between performance and consumption. The 440i (B58) is a favorite for its reliability and performance. The 430i (B48) is an excellent versatile choice. * If you opt for a pre-LCI model (2013-2016): * Petrol (N20/N26): Be extremely vigilant about the service history and any timing chain replacement. A model whose chain has been replaced with an improved version is preferable. Otherwise, negotiate the price heavily to anticipate this costly repair. * Diesel (N47): Imperatively check that the EGR cooler recall has been performed. Pay attention to chain noises, although the risk is lower than on N47s of previous generations. * Regardless of the model: A complete and clear service history is crucial. The ZF 8HP automatic gearbox is robust, but a preventive fluid change ever
