2017 BMW 3 Series 330e review - price, specs and release date

Score 96.6%

Only 14% of 3 Series we were told about had a problem, with two areas the most frequently cited: non-engine electrics and the engine. The vast majority of cars could still be driven and were repaired the same day. All work was carried out under warranty.

Score 96.9%

Alfa Romeo has hardly been historically renowned for reliability, but the Italian brand’s new Giulia saloon is bucking that trend so far. While 17% of cars had a fault, most were minor, such as issues with the air conditioning, brakes and exterior lights (all 4%). Three-quarters of these Giulias could still be driven and all were fixed under warranty.
