Used buying checklist
KIA Sorento reliability, common problems and used buying checks
A used KIA Sorento looks worse than average for reliability in UK MOT data: 21.5% of 44,545 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for corrosion and structure, suspension and steering, and lights and electrical.
It can be, if the exact car has a clean history for corrosion and structure, suspension and steering, and lights and electrical.
Start with corrosion and structure, suspension and steering, and lights and electrical, then compare the car's mileage and recall record below.
Sources used: DVSA MOT tests (Apr 2026); vehicle recalls (Apr 2026); MOT fault wording (May 2025). MOT data does not capture every reliability issue, especially intermittent engine, gearbox or infotainment faults that do not appear during the test.
- 21.5% MOT failure rate
- Median tested mileage 80,127 miles
- 9,565 failed MOT tests analysed
Corrosion and structure is the clearest area to check
Corrosion and structure is the clearest named problem area in this model's MOT history (42.4 MOT notes per 100 tests). Example MOT phrases from this area include excessively corroded, corroded and seriously weakened, and corroded to the extent that the rigidity of the assembly is significantly reduced.
Example MOT phrases to search in the car's history:
- excessively corroded
- corroded and seriously weakened
- corroded to the extent that the rigidity of the assembly is significantly reduced
- or chassis has excessive corrosion, seriously affecting its strength within 30cm of a cab mounting
- ball joint has excessive play
- ball joint dust cover damaged or deteriorated, but preventing the ingress of dirt
- ball joint excessively worn
- ball joint dust cover no longer prevents the ingress of dirt
- warning lamp indicates a fault
- has a product on the lens so that the light output is severely reduced

Should you buy a used KIA Sorento?
78.5% of the MOT tests we analysed for this model passed. The model's recorded failure rate is 21.5%, +2.7 percentage points compared with the average across all models. This is a buying brief for the exact car in front of you: clean repeat history matters more than badge reputation.
- Repeat unresolved MOT notes for corrosion and structure, suspension and steering, and lights and electrical
- corrosion and structure appearing across more than one MOT
- Any dangerous MOT failure on the exact car, especially if the same area appears again later
- No paperwork showing applicable recall work has been completed
- A seller who cannot explain MOT wording such as "excessively corroded"
It can be, if the exact car has a clean history for corrosion and structure, suspension and steering, and lights and electrical.
Start with corrosion and structure, suspension and steering, and lights and electrical, then compare the car's mileage and recall record below.
Corrosion and structure is the clearest named problem area in the MOT history (42.4 MOT notes per 100 tests). These counts are issue notes, not failure rates, because a single MOT can list several faults.
Past 100k miles on the KIA Sorento, MOT records most often point to corrosion and structure, suspension and steering, and lights and electrical.
The MOT failure rate rises from 7.8% at 0-3 years to 31.2% at 15+ years. Compare the car with the nearest age range before treating a fault as normal wear or a warning sign. The average MOT failure rate across all models in the same dataset is 18.7%.
Start with corrosion and structure, suspension and steering, lights and electrical, and emissions, engine, and exhaust. The checklist on this page explains why each area is being recommended, what to inspect, and what to ask the seller.
6 relevant recall notices appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.
