- Brake pads: wearing thin149.6
- Rigid brake pipes: corroded, covered in grease or other material108.0

Checking a used Kia Sorento before you buy
Against cars of the same age, the Kia Sorento fails more often than average on suspension, brakes and steering. Start there.
Suspension
Drive over speed bumps with the radio off and listen for knocks. Look at the car side on: a corner sitting lower than the others often means a broken coil spring.
Brakes
Look through the wheel spokes at the discs for a deep lip or scoring, check the handbrake holds the car on a slope, and feel for a pull to one side when braking hard.
Steering
With the engine running, rock the wheel gently: there should be almost no free play. Listen for knocks on full lock and look for power steering fluid leaks.
Averages only take you so far. The specific car's MOT history shows whether it has already failed on any of these, how often advisories were ignored, and whether the mileage climbs steadily from test to test. Read our guide to reading a car's MOT history before you go to view it.

How these figures are calculated
Source: DVSA Anonymised MOT tests and results, 2025 release. We count first tests of cars and small vans (class 4) aged 3 to 20, so a car that fails and is retested is counted once. A failure includes faults fixed and passed within the same visit. The same age average weights the national failure rate for each age by how many Kia Sorento cars of that age were tested, so a model is never penalised for having an older fleet. Make and model are as recorded at the test; trim levels are combined. Full method and rankings.
