BMW build quality is high but reliability suffers from complex turbo direct-injection engines (N20, N55, B58), known timing chain guide failure on N20 (2012-2015), high-pressure fuel pump failures on N54 (2007-2013), oil filter housing gasket leaks, electric water pump failures, and Valvetronic motor issues. The B58 inline-6 (2016+) is the brand's most reliable modern engine. iDrive infotainment is excellent. Out-of-warranty repair costs are 2-3x mainstream brands.
BMW typically ranks in the bottom third of J.D. Power's Vehicle Dependability Study. Consumer Reports rates BMW mid-pack but flags very high repair costs.
Inline-6 B58 is one of the most reliable BMW engines ever built.
B58 + ZF 8HP - bulletproof drivetrain combo.
N55 or S55 / S58 - performance cars but with attentive owners.

Build quality is high but mechanical reliability is below average. Expect more repairs than a Toyota or Honda, but they are well-built when working.
The 2012-2015 N20 2.0T had timing chain guide failure as early as 60K miles. Repair runs $4-7K. Class action settled.
