Best and worst executive cars for reliability
The best executive cars must be rewarding to drive, practical, economical and dependable...
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.
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.
Although 19% of Vauxhall Insignias had a fault, most cars were fixed the same day. Engine electrics accounted for the highest number of problems (8%), while other issues were divided between the wheels and tyres, fuel system and exterior lights (all 4%). All work was carried out for free.
