BMW X4 F26 (2014–2018) (2014 – 2018)

Reliability score : 8.2/10

The BMW X4 F26, launched in 2014, marked the arrival of the first generation of the Bavarian brand's "Sports Activity Coupé" (SAC) in the premium compact SUV segment. Based on the X3 F25 platform, it distinguishes itself with its sloping coupé-like roofline, offering a more dynamic and sporty aesthetic, at the expense of slightly reduced rear passenger space and trunk volume. Positioned as a more emotional alternative to the X3, it targets customers seeking a blend of SUV versatility and coupé dynamism. Overall, the X4 F26 benefits from the proven technical foundations of the X3, offering satisfactory reliability, although certain engines and the first years of production require particular attention.

⚠️ Weaknesses

🎯 Verdict

The BMW X4 F26 is an attractive choice for those seeking a compact SUV with a strong personality, assertive design, and dynamic road handling. Its reliability is generally good, especially with the 6-cylinder engines (N55 petrol and N57 diesel), which are safe bets, known for their robustness and driving pleasure. The 4-cylinder diesel versions (B47) are also reliable, provided that the EGR recalls have been carried out and the usage is appropriate (avoid frequent short urban trips). Caution is advised with the first versions of the N20 4-cylinder petrol engine (before mid-2015) due to the risk of timing chain issues. If you opt for an N20 from this period, ensure that the chain has been replaced or negotiate the price accordingly to cover any potential intervention. A complete service history and a thorough pre-purchase inspection by a professional are absolutely crucial to minimize risks. If these conditions are met, the X4 F26 can be an excellent road companion, offering undeniable driving pleasure and appreciable comfort on long journeys. It is a vehicle that requires rigorous maintenance but repays it in return.
