BMW X1: Pre-Purchase Inspections Recommended for Engine Reliability
BMW X1 owners and potential buyers should be aware of potential engine and drivetrain issues across different generations. A pre-purchase inspection is advised to ensure the specific vehicle's reliability.
The first-generation BMW X1 (E84) offered reliable engines, including the N20 and N55, but may require attention to the timing chain and oil leaks around the turbocharger. The second-generation (F48) is considered the most reliable overall, with a low defect rate according to the 2025 TÜV report. However, it may require regular coolant and oil level checks. The third-generation (U11) uses the B48 engine, with the M35i xDrive model having significant mechanical improvements. Pre-purchase inspections are recommended to assess the specific condition of each vehicle.
Second-generation X1s may face engine mount issues causing knocking during acceleration and rear differential fluid and vent line issues in xDrive models. The BMW X1 has evolved from a rear-wheel-drive, 3 Series-based crossover to a modern, tech-filled compact SUV over three generations.
Potential buyers should consider the reliability of each generation and the specific condition of the vehicle. Regular maintenance and pre-purchase inspections are crucial to ensure a reliable BMW X1 ownership experience.
