Is the BMW N62 / N63 reliable?

The N62 (naturally aspirated V8, 2001-2010) is considered a solid engine, with the coolant hoses and valve stem seals as points to watch. The N63 (twin-turbo V8, since 2008) has a worse reputation: oil consumption from the seals, the timing chain and coolant loss; the post-July 2013 N63TU is considered more reliable.^{[1][2][3][4][5]}

Is the 1.5 VC-Turbo e-Power reliable?

There is still little reliability data: the three-cylinder 1.5 VC-Turbo only generates electricity and no mechanical faults are known in Europe. The documented weak points are in the e-Power electronics: battery campaigns and isolated cases of immobilisation.^[6][7][8]
