Quick summary
Total: 325 cars
The 2009 Mazda BT-50 has an overall defect rate of 338 per 100 vehicles, which is 9% higher than the average for cars of the same year. Notably, it performs better than average in the Wheels, Suspensions & Axles category, with a defect rate significantly lower than expected. However, it shows weaknesses in several areas, particularly in Brakes, Steering, and Lights & Electrics, where defect rates exceed the average by substantial margins. Mileage trends indicate a rising defect rate with higher mileage, particularly in the 93,000–124,000 mile range. Overall, while the BT-50 has some strengths, it also presents several significant concerns that car owners should monitor.
