What's good
All models in the line-up, including the Sorento ‘2’, feature LED technology for the headlights and rear combination lights, as well as for the daytime running lights, front and rear fog lights and high mounted brake light. 17-inch alloy wheels and a temporary space saver spare wheel are standard equipment, with roof rails not only boosting the the Sorento visually, but also adding versatility if there is ever a need to carry additional loads. A black front radiator grille is married to wheel arch body mouldings and side sills in the same colour, with all versions featuring front and rear skid plates in silver.
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Sorento 4 Hev Awd Auto and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
