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 E-Tech Híbrido reliable?

The E-Tech combines a combustion engine (1.6 H4M naturally aspirated or 1.2 HR12 turbo) with electric motors and a multi-mode gearbox with no clutch or torque converter. Its best-documented weak point is the gearbox itself: reports from the Clio, Captur, Arkana, Austral, Duster and Jogger describe warnings of a risk of breakage, and Renault has launched two campaigns since 2020 (an electrical fault and a primary shaft seal). The 12 V battery also fails fairly often.^[6][7][8]
