Mazda BT-50 II (UP/UR) (2011 – 2020)

Reliability score : 7.7/10

The second-generation Mazda BT-50 (UP and UR series) marks a stylistic departure from its predecessor. Developed in close collaboration with Ford, it shares its platform (T6), engines, and transmissions with the famous Ford Ranger. While its curvy design (nicknamed the 'smiley face') divided traditional pickup customers, its underpinnings are extremely robust. It boasts excellent towing capacity (up to 3,500 kg) and a generous payload. Data from ADAC and TÜV confirm good overall reliability, inherited from this joint design, with a 3-year defect rate of 11% (TÜV) and a breakdown rate of 2.5/1000 vehicles/year (ADAC).

✅ Strengths

Very robust ladder chassis (Ford Ranger T6 platform)
Excellent towing capacity (3,500 kg on the 3.2L)
Smooth and very reliable 6-speed Aisin automatic gearbox
Very capable 3.2L 5-cylinder engine under load
Often cheaper on the used market than its twin, the Ford Ranger

⚠️ Weaknesses

Polarizing exterior design (especially phase 1 before 2015)
Very firm rear suspension when unladen (leaf springs calibrated for load)
Dangerous oil change procedure on the 3.2L if executed poorly (risk of engine failure)
Quality of some interior plastics below usual Mazda standards
Imposing size making urban parking difficult

🎯 Verdict

The Mazda BT-50 (UP/UR) is an excellent choice for those seeking the undeniable qualities of the Ford Ranger T6 (robustness, off-road and towing capabilities) at an often lower price on the used market, due to its less consensual design. The 3.2L 5-cylinder engine is the preferred choice for high-mileage drivers and those who tow heavy loads, but it requires rigorous maintenance, especially during oil changes (risk of the oil pump losing its prime). The automatic gearbox is highly recommended for its drivability and reliability. It is a formidable workhorse that ages well if maintenance is not neglected.
