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.[1][2][3]

Is the Rover K-Series reliable?

The Rover K-Series has one very well-known fault: the head gasket, which according to Diariomotor can fail at under 100,000 km and which technical sources link to a small cooling circuit and a badly placed thermostat. The usual repair uses the multi-layer (MLS) gasket developed for the Freelander; the other two documented faults (sunken liners and coolant leaks) are related to that same circuit.[4][5][6][7]
