BMW Série 5 F10/F11 (2010 – 2017)

Reliability score : 7.2/10

The sixth-generation BMW 5 Series (F10 sedan, F11 Touring wagon, and F18 long-wheelbase version for China) marks a return to classicism after the controversial Chris Bangle era (E60). Positioned as a benchmark premium executive car, it shares its architecture with the 7 Series (F01), which gives it imperial comfort, high-level sound insulation, and impeccable finish quality. On the other hand, it carries a significant weight. The mid-2013 facelift (LCI) is crucial: it corrects many early flaws, modernizes the infotainment (transition to the iDrive NBT system), and gradually introduces new, much more reliable engines (notably the transition from the criticized N47 to the robust B47 diesel).

✅ Strengths

Exceptional ride comfort and sound insulation worthy of the 7 Series
Masterful ZF 8-speed automatic gearbox (ZF8HP) (responsiveness and smoothness)
Enjoyment and fuel efficiency of 6-cylinder diesel engines (530d)
Interior finish quality and material aging
iDrive infotainment system (especially the NBT version from 2013 onwards)
Imperial road handling on the highway

⚠️ Weaknesses

Disastrous timing chain reliability on the 2.0d N47 (2010-2014)
Catastrophic reliability of the 550i's V8 (N63)
Very high weight (often > 1800 kg) leading to rapid wear of brakes and tires
Rear air suspension on the Touring wagon (F11) prone to leaks
Very high maintenance and spare parts cost at official dealerships
Imposing size making urban use tedious

🎯 Verdict

The BMW 5 Series F10/F11 is a fantastic executive car, but its reliability record is split in two. Early production models (2010-2013) are plagued by costly problems (N47 diesel timing chain, N63 V8 gasoline). In contrast, facelifted versions (LCI from mid-2013, and especially 2014 for the arrival of the B47 engine) are excellent choices. The best diesel buy is a 520d (B47 engine with 190 hp, post-2014) for practicality, or a 530d (N57 with 258 hp) for passion. Avoid 550i models and 520d models from before 2014 without a clear service history. Demand a vehicle with the EGR recall performed and an automatic gearbox that has been serviced.
